The terms that govern BarkLens.

1. BarkLens Terms of Use

Effective: September 16, 2026

These Terms of Use (the “Terms”) are a binding contract between you and ThinkTanc LLC, a Delaware limited liability company doing business as BarkLens (“BarkLens,” “we,” “us,” or “our”). They govern your use of the BarkLens mobile application, the barklens.com website, and every related feature, tool, and service we make available (together, the “Service”). “You” means the individual who accesses or uses the Service and, where applicable, the account owner who invites another person to a Care Team.

🚨 EMERGENCY USE — READ FIRST

BarkLens is not for emergencies. BarkLens does not monitor your dog, does not watch for problems, and will not tell you when something is wrong.

If your dog is or may be in a medical emergency — collapse, difficulty breathing, non-productive retching or a distended abdomen, seizure, uncontrolled bleeding, suspected poisoning or toxin ingestion, inability to urinate, trauma, heatstroke, sudden severe pain, or any change that frightens you — stop using the app and contact a licensed veterinarian or an emergency animal hospital immediately. Call your veterinarian, call the nearest emergency animal hospital, or call an animal poison control center. Do not wait for an answer from BarkLens, do not use BarkLens to decide whether the situation is urgent, and do not treat the absence of an alert, a flag, a notification, or any other output from BarkLens as an indication that your dog is not in danger.

Silence from BarkLens is never clearance. BarkLens is never the watcher.

BarkLens does not contact veterinarians, emergency services, animal poison control centers, or any other person on your behalf. It does not place calls, dispatch help, notify a clinic, or transmit a record to anyone unless you take the action that does so yourself.

1.1 Acceptance of these Terms

By downloading, installing, creating an account on, subscribing to, or otherwise using the Service, you agree to these Terms and to the Privacy Policy at §2, the Subscription and Billing Terms at §3, the Email and Waitlist Terms at §4, the Data Retention and Deletion Schedule at §6, the Vendor and AI Processing Disclosure at §7, and the Care Team Sharing Terms at §8, each of which is incorporated into these Terms by reference and forms part of your agreement with us. If you do not agree to all of them, do not use the Service.

If you are accepting these Terms on behalf of an organization — for example, a rescue, a breeder, a boarding facility, or a veterinary practice — you represent that you have authority to bind that organization, and “you” means both you and that organization. BarkLens is presently offered as a consumer service; it is not offered as a clinic, veterinary-practice, employer, or enterprise system. You also agree to any additional terms we present for a specific feature or promotion at the time you use it, and only a written amendment signed by an authorized officer of ThinkTanc LLC may modify these Terms.

1.2 Eligibility; who may use the Service

1.2.1 Age. You must be at least eighteen (18) years old to create an account or use the Service. The Service is not offered to, and must not be used by, anyone under 18. We do not knowingly permit accounts for minors, and we do not knowingly collect personal information from anyone under 18. If we learn that an account belongs to someone under 18, we will close it and delete the associated data as described in §6.

1.2.2 Geography. The Service is offered only in the United States, in all fifty states and the District of Columbia. We do not offer, market, or support the Service outside the United States, and we make no representation that the Service or its content is appropriate or lawful anywhere else. If you access the Service from outside the United States, you do so on your own initiative and at your own risk, and you are responsible for compliance with local law. Content in the veterinary source library is drawn from published sources that may reflect regulatory approvals, product availability, and clinical practice that differ from those in your location.

You must be located in the United States when you create an account or use the Service, and you may not use the Service for or on behalf of a person under 18. If we reasonably believe that you do not satisfy the eligibility conditions in this §1.2, we may suspend or terminate access.

1.2.3 Capacity and authority over the animal. You represent that each dog for which you create a profile is a dog you own or for which you are lawfully responsible, and that you have the right to upload the records, labels, invoices, images, and other materials you submit about that dog.

1.2.4 Account requirement. Some features require an account. You agree to provide accurate registration information, to keep it current, and to be responsible for everything that happens under your account, as described in §1.11. You represent that the information you provide is accurate and that your use of the Service complies with applicable law.

1.3 What BarkLens is, stated precisely

1.3.1 The two things the Service does. BarkLens does two things, and it is important that you understand both of them exactly.

First, it holds and organizes your dog’s history. You photograph or upload the documents you already have — veterinary records and lab reports, prescription and supplement labels, food packaging and guaranteed-analysis panels, product and treat packaging, and photographs of your dog’s stool — and BarkLens reads them, extracts the values printed on them, and arranges them into a chart that grows over time. Every fact in that chart carries a pointer back to the document it came from, or an explicit statement that you entered it yourself. The chart is a record-keeping and preparation tool. Its purpose is to let you, and any veterinarian you choose to show it to, see what your dog’s own documents actually say and when.

Second, it answers questions with published veterinary literature. When you ask a question, BarkLens draws on a curated library of passages quoted from published veterinary sources — veterinary journals and peer-reviewed literature, the Merck Veterinary Manual, professional-association guidelines and consensus statements, teaching-hospital and university references, and drug labeling — and gives you an educational answer that links to the passage it relied on so you can read the original yourself. Answers become more specific as your dog’s chart fills, because a question asked with a lab report on file can be answered against the numbers on that report, while the same question asked with nothing on file can only be answered in general terms.

1.3.2 Two things BarkLens may do with your own documents. Within the Service, BarkLens may read and repeat what a document says and attribute it to that document (“the label states,” “as printed on the report”), and it may perform arithmetic against an instruction your veterinarian already gave (“the label directs one tablet twice daily; you have recorded eleven tablets remaining”). Repeating and calculating are not the same as advising. BarkLens does not originate clinical instructions, and the arithmetic it performs is a convenience, not a verification. You remain responsible for checking any number against the original document and against your veterinarian’s directions.

1.3.3 What BarkLens is not. BarkLens is not a veterinarian, a veterinary practice, a telemedicine service, a diagnostic tool, a monitoring or alerting system, a substitute for examination of your dog, or a source of treatment. It does not examine your dog, it does not know anything about your dog other than what you or the people you invite put into it, and it cannot see anything a photograph does not show. It is an organizing and educational tool for informed owners, and nothing more. It is not a veterinary practice, a clinic, a pharmacy, a laboratory, a medical device, an emergency service, or a remote-monitoring service. Feature descriptions in this §1.3 and in §3 describe what the Service does today; they are not promises of indefinite availability or of performance in every circumstance.

1.3.4 Photo capture is limited to supported categories. The camera and image-processing features support: (a) stool, (b) food labels, guaranteed-analysis panels, and photographed meals, (c) medication and supplement labels, (d) product, treat, and chew packaging, and (e) veterinary records and lab reports. BarkLens does not assess skin, coat, wounds, lumps, masses, eyes, ears, teeth, gums, gait, posture, or body condition, and it does not evaluate photographs of your dog’s body. If you submit an unsupported image, the Service may refuse it or misread it. Do not rely on image output for diagnosis, urgent review, or physical examination.

1.3.5 No email or inbox integration at launch. BarkLens does not connect to, read, or import from your email account. There is no email or inbox integration of any kind in the Service at launch. Any statement or expectation to the contrary — including in earlier marketing material, press coverage, beta communications, or community discussion — is wrong. Records enter the Service only when you put them there. We do not undertake to locate a missing record, to obtain records from your veterinarian, to synchronize an inbox or a clinic portal, or to determine whether what you have submitted amounts to a complete chart. You must deliberately choose and submit each supported item through the methods the Service makes available.

1.4 No veterinarian-client-patient relationship

Using BarkLens does not create a veterinarian-client-patient relationship (“VCPR”) between you and BarkLens, between you and any veterinarian who reviewed material in the source library, or between you and any author of any source cited in the Service. No veterinarian employed or engaged by BarkLens examines your dog, takes responsibility for your dog’s clinical care, or assumes any duty toward you or your dog. A VCPR under applicable state law requires a licensed veterinarian to assume responsibility for clinical judgments about a specific animal, with sufficient knowledge of that animal to make at least a general or preliminary diagnosis, ordinarily following examination or medically appropriate visits. Nothing in the Service satisfies that standard and nothing in the Service is intended to. No such relationship arises between you or your dog and BarkLens, any BarkLens employee or contractor, any veterinarian who reviews sources for the library, any author or publisher of a source, or any model or technology provider, and none arises merely because a source was reviewed, displayed, quoted, linked, summarized, or used by the Service. Library reviewers assess sources for admission to the library; they do not know your dog’s facts and they do not provide consultation, diagnosis, prescription, or individualized care. You should maintain a relationship with an appropriately licensed veterinarian who can examine your dog.

It follows, and you agree, that:

• BarkLens cannot and does not prescribe, dispense, recommend, adjust, discontinue, or authorize any medication, supplement, diet, therapy, procedure, or test for your dog;
• no output of the Service is a veterinary order, a prescription, a treatment plan, a discharge instruction, or a clinical recommendation, and no output may be presented to any pharmacy, retailer, insurer, laboratory, or clinic as though it were;
• only your own veterinarian, having examined your dog, can make clinical decisions about your dog; and
• your veterinarian’s instructions always govern. If anything in the Service appears to conflict with what your veterinarian told you, follow your veterinarian and contact your veterinarian’s office. Do not resolve the conflict yourself using the Service.

1.5 No diagnosis, prognosis, treatment, dosing, or clinical recommendation — the six limits

The Service is built and operated within six hard limits. These limits are not marketing language; they are constraints on what the product is permitted to say, and they define the boundary of what you may rely on. We state them here verbatim as they are written into our internal answer doctrine, and they apply to every screen, answer, chart row, notification, label, and output of the Service:

1. No diagnosis for this dog.
2. No dose, interval, or schedule originated by the app.
3. No clearance for this dog — the Service does not say that anything is “safe,” “fine,” “normal,” “okay,” or “adequate” for your dog.
4. No prediction for this dog.
5. No “no action needed.”
6. The app is never the watcher.

Read as operative contract terms, those six limits mean the following.

1.5.1 No diagnosis. The Service does not diagnose, and does not attempt to diagnose, any disease, condition, injury, infection, deficiency, toxicity, or abnormality in your dog. When the Service shows that a value on your dog’s report sits outside the reference interval printed on that report, it is repeating the report — not making a finding. When the Service describes what a published source says about a condition, it is describing literature — not telling you your dog has that condition. Any statement in the Service that resembles a diagnosis is an error; do not act on it, and please report it to us at info@barklens.com.

1.5.2 No dose, interval, or schedule of our own. The Service never originates a dose, a dosing interval, a frequency, a duration, a titration, a taper, or an administration schedule for your dog. It will quote a dose printed on a label or written in your dog’s record and attribute it to that document, and it will do arithmetic against a schedule your veterinarian already set. It will not tell you how much to give, when to give it, when to stop, or whether to change anything. Dose calculators are deliberately absent from the Service. If you need a dose, an interval, or a change to either, that comes from your veterinarian.

1.5.3 No clearance. The Service does not clear your dog, your dog’s food, your dog’s medication, a product, a value, a trend, or a situation. It does not say “safe,” “fine,” “adequate,” “nothing to worry about,” or any equivalent, about your dog. The absence of a caution is not a clearance. The absence of an answer is not a clearance. Silence is not clearance. If you want to know whether something is safe for your dog, ask your veterinarian.

1.5.4 No prediction. The Service does not predict what will happen to your dog. It does not forecast disease onset, progression, remission, survival, response to treatment, life expectancy, or outcome. Published statistics about populations of dogs, when the Service shows them, describe those populations as reported in the literature — they are not statements about your dog, and they must not be read as statements about your dog.

1.5.5 No “no action needed.” The Service will never tell you that nothing needs to be done. It cannot know that. Escalation is always available to you and always appropriate when you are concerned: you may always call your veterinarian, and nothing in the Service should ever discourage you from doing so. If you are wondering whether to call, call.

1.5.6 The app is never the watcher. BarkLens does not monitor your dog and does not undertake to notice anything. It has no ability to observe your dog, no continuous data feed, no clinical oversight, and no duty of vigilance. Watching your dog is your job and your veterinarian’s job. Anything the Service surfaces is surfaced from what you gave it, when you open it, and nothing more.

1.5.7 Educational purpose. All content in the Service, including chart projections, question-and-answer output, source passages, summaries, comparisons, “questions to ask your vet,” trend indications, and library articles, is provided for general education and record-keeping only. It is not a clinical recommendation, and you use it at your own discretion and risk.

1.5.8 What you must not do with the Service. Do not use the Service to start, stop, change, substitute, combine, or time a medication, supplement, diet, treatment, or procedure, and do not use it to delay an examination, a test, a treatment, a refill, a recheck, or an emergency call. If source material displayed in the Service appears to conflict with your veterinarian’s instructions, the veterinarian’s instructions govern, and you should contact the veterinarian.

1.6 No detection, alert, notification, completeness, or timeliness guarantee

1.6.1 No detection. We do not represent, warrant, or promise that the Service will detect, identify, catch, surface, flag, or bring to your attention any condition, abnormality, error, interaction, contraindication, missing record, overdue item, deteriorating trend, or risk of any kind, whether or not the underlying information is present in your dog’s records or in our source library. The Service may miss things that matter. It may miss things that are plainly visible in a document you uploaded. You must not use the Service as a safety net, a second opinion, a review process, or a check on anyone’s work.

1.6.2 No alerts or notifications. Any reminder, badge, indicator, “changed and open” item, trend indication, or push notification the Service may provide is a convenience feature offered without warranty. We do not guarantee that any notification will be generated, delivered, delivered on time, delivered to the right device, or seen by you. Notifications depend on your device, operating-system settings, network conditions, battery and background-activity settings, app-store platform behavior, and third-party services outside our control. Never rely on a BarkLens notification for anything that matters to your dog’s health. Conversely, the absence of a notification means nothing at all. You must not structure care, medication administration, recordkeeping, or emergency planning around the receipt of a BarkLens notification. Any notification is a supplemental convenience only.

1.6.3 No completeness. We do not warrant that your dog’s chart is complete, that it contains every record, value, medication, allergy, vaccination, visit, or instruction relevant to your dog, or that it accurately reflects your dog’s medical history. The chart contains only what you and your Care Team put into it, as read by automated systems. Gaps are expected, common, and often invisible. Where the Service displays a coverage statement — for example, that a chart was built from four records with an eleven-month gap — that statement describes the documents on file, not your dog’s actual history.

1.6.4 No timeliness. We do not warrant that information in the Service is current. Source literature is versioned, drug labeling changes, guidelines are revised, and our library is updated on our own schedule. Your own records reflect the date they were created, not today. Values change; the chart does not know that until you upload something new.

1.6.5 No uptime guarantee. The Service may be unavailable, delayed, degraded, or interrupted at any time, with or without notice, for maintenance, updates, vendor outages, or reasons outside our control. Do not build any care routine on the assumption that the Service will be available when you need it. Keep your own copies of anything you cannot afford to lose; export is always available to you under §3.9.

1.7 Your uploads, and the limits of reading a photograph

1.7.1 You are the source. The Service operates on material you supply. You are solely responsible for the accuracy, legibility, completeness, and lawfulness of everything you upload, photograph, type, or import, and for confirming that each item is attributed to the correct dog.

1.7.2 Optical character recognition and extraction are imperfect. BarkLens reads documents and photographs using automated optical character recognition and machine-learning extraction. These systems make mistakes. Known and expected failure modes include, without limitation:

• misread characters and numbers — a digit, a decimal point, a unit, a minus sign, or a reference-range bound read incorrectly, which can change a value’s meaning entirely;
• obscured or unreadable print — glare, shadow, blur, motion, fold lines, staples, thermal-paper fading, low-contrast printing, handwriting, stamps, watermarks, small-point footnotes, and text running off the edge of the frame;
• partial capture — a multi-page record photographed incompletely, a second page never captured, a column cut off, or a continuation page missed, with no indication that anything is missing;
• structural misreading — a value associated with the wrong analyte, the wrong date, the wrong specimen, the wrong reference interval, or the wrong laboratory;
• wrong-dog attribution — a record filed to the wrong dog profile in a multi-dog household, particularly where the document does not clearly name the patient or names more than one animal. Where the Service suggests a dog, it asks you to confirm; the confirmation is yours, and so is the consequence of confirming wrongly;
• stale or superseded documents — an old label or discontinued prescription read as current because it was uploaded today.

1.7.3 Your obligation to verify. Every value that matters must be checked against the original document, and every clinical question must be taken to your veterinarian. Do not rely on a transcribed value in the Service for any purpose where an error would matter — including administering medication, deciding whether to seek care, or reporting history to a clinician — without confirming it against the source document, which the Service links for exactly that reason.

1.7.4 Reference intervals belong to the laboratory that printed them. A reference range is a property of the laboratory and method that produced the result. The Service preserves the range printed on each report and does not substitute a universal range. For the same reason, results from different laboratories or different methods may not be comparable, and the Service does not warrant that any comparison, trend, or series it displays is clinically meaningful. Interpretation of laboratory data is a veterinary act.

1.7.5 Owner observations are yours. Where the Service invites you to record an observation — including a suggested stool score offered against a published scoring chart — the suggestion is a prompt and the recorded value is your observation, attributed to you, not a finding by BarkLens. You may accept, change, or reject any suggestion.

1.7.6 An accepted upload is not an assessed upload. Image handling is scoped to the five capture categories in §1.3.4. If the interface accepts an image outside those categories — because of an error, an ambiguous upload, or a permissive file picker — that acceptance does not mean the image was clinically assessed, reviewed, or evaluated for any purpose. Do not submit photographs for diagnosis, urgent review, or physical-examination purposes.

1.7.7 Other people’s information in your dog’s paperwork. You are responsible for confirming that each upload belongs to the correct dog, is lawful for you to submit, and does not contain information you lack authority to share. Veterinary records often carry personal information about you, about clinic staff, and sometimes about third parties. Before uploading, review the material and remove unrelated Social Security numbers, payment-card numbers, human medical information, and information about people or animals who are not part of your authorized account. The Service is not designed, configured, or contracted to receive human medical records or protected health information about people.

1.8 The source library and the limits of generated answers

1.8.1 What is reviewed, and by whom. Every source in the BarkLens veterinary library is reviewed by a licensed veterinarian before it is admitted, and every claim in the library is tied to a specific passage in a named, published source that you can open and read. That review is real, it is documented, and it is a gate: material that fails it is withdrawn or marked unproven rather than quietly kept.

1.8.2 What is not reviewed. Answers generated for you are not individually reviewed by a veterinarian. No veterinarian reads your question, no veterinarian approves the response before you see it, and no veterinarian confirms that the passage retrieved for your question is the right passage for your dog. The veterinary review described in §1.8.1 is scoped to the library, not to individual answers. Any statement anywhere — in the app, in the store listing, on the website, in advertising, or in a review — that describes BarkLens answers as “vet-reviewed,” “vet-approved,” “vet-checked,” or “reviewed by a veterinarian” is inaccurate, is not authorized by us, and must not be relied on. If you see such a statement in our own materials, please tell us at info@barklens.com so we can correct it.

1.8.3 Automated generation and its failure modes. Answers are produced with the assistance of third-party artificial-intelligence models (see §7). Those systems can retrieve the wrong passage, apply a passage outside the population or life stage it covers, misstate a source, omit a material qualification, or produce fluent text that is wrong. Output may be inconsistent between sessions. Fluency is not accuracy, and a citation is not a warrant that the cited source applies to your dog. Read the linked passage; it is there so you can check us.

1.8.4 Sources describe populations, not your dog. Published literature describes studies, cohorts, breeds, species, and labeled products. A source that is correct about a population may be irrelevant, misleading, or harmful if applied to an individual animal. The Service does not, and cannot, decide whether a given source applies to your dog. Only a veterinarian who has examined your dog can do that. Facts shown next to one another do not establish causation, diagnosis, interaction, clinical significance, or a recommendation, and arithmetic performed against an instruction may rest on a wrong transcription, date, unit, or premise. Verify the source and the original document.

1.8.5 Third-party content and links. The Service quotes and links to material owned by third parties. Those quotations are provided for reference and attribution. We do not control third-party sites, we do not endorse them, and their content is governed by their own terms. Links may break, and cited pages may change or be withdrawn. A source’s review status reflects the source as it stood when it was admitted; it may not reflect later changes to that source, and it does not speak to every jurisdiction or circumstance.

1.9 Care Team access, and what you accept when you invite someone

The Service allows you to invite other people — a spouse or partner, an adult child, a dog walker, a sitter, a co-owner, a rescue coordinator, or your veterinary practice — to see and, if you choose, to contribute to a dog’s record. The full terms are in §8 (Care Team Sharing Terms), which is incorporated here. In summary, and as operative terms:

Care Team access is a coordination convenience. It does not make BarkLens the custodian of a formal veterinary chart, and it does not make any Care Team member a veterinarian, an agent, a fiduciary, an emergency contact, or a legally authorized decision-maker for your dog.

1.9.1 You control the invitation and the scope. Access exists only because you granted it, only to the people you named, and only to the parts of the record you selected.

1.9.2 You are responsible for whom you invite. You represent that you have a legitimate basis for sharing your dog’s record with each person you invite, and you accept responsibility for their access, their conduct within the shared record, and anything they add. We do not screen, verify, credential, or supervise invited people.

1.9.3 Contributions by others are not verified. Anything a Care Team member adds — a value, an observation, a confirmation, a document — enters the record as their entry. We do not check it, and it may be wrong.

1.9.4 Revocation is prospective only. You may remove a member at any time, and access to the record ends. But information a person has already seen cannot be un-seen. We can end access; we cannot retrieve what someone remembers, wrote down, screenshotted, exported, forwarded, or printed. Share accordingly.

1.10 Acceptable use

You agree that you will not, and will not attempt to, and will not permit anyone using your account or your Care Team access to:

1.10.1 Upload other people’s information. Upload, submit, or enter any human medical record, protected health information, human laboratory result, human prescription, insurance identifier, government identifier, financial-account number, or other personal information about any person other than yourself, except information about yourself that appears incidentally on your dog’s own veterinary paperwork (for example, your own name and address on a clinic invoice). Do not upload a person’s medical records to BarkLens. The Service is for dogs, it is not a HIPAA-covered environment, and it is not designed, configured, or contracted to hold human health data.

1.10.2 Upload material you do not have the right to upload. Submit content that infringes any copyright, trademark, trade secret, publicity, or privacy right, or that you are contractually prohibited from disclosing.

1.10.3 Use the Service for clinical practice. Use the Service to practice veterinary medicine; to diagnose, treat, prescribe for, or advise on any animal other than your own; to provide veterinary advice to third parties; to substitute for examination of an animal in your professional care; or to generate content presented to any person as veterinary advice, a prescription, a veterinary order, or a clinical recommendation. You also may not use the Service for a clinic, a commercial veterinary practice, a pharmacy, an insurer, an employer, a researcher, a data broker, or any other institutional purpose without our written agreement.

1.10.4 Extract, scrape, or copy the library. Access, index, harvest, mirror, or systematically copy any portion of the Service or the veterinary source library, whether manually or by any robot, spider, crawler, headless browser, script, API client, or other automated means; circumvent rate limits, page limits, or access controls; or use the Service to build, train, fine-tune, evaluate, or benchmark any machine-learning model, dataset, index, or competing product.

1.10.5 Reverse engineer. Decompile, disassemble, reverse engineer, or attempt to derive the source code, model prompts, retrieval logic, ranking rules, schema, or internal doctrine of the Service, except to the limited extent that applicable law expressly prohibits this restriction.

1.10.6 Interfere or intrude. Probe, scan, or test the vulnerability of any system; breach or circumvent any authentication or security measure; access any account, data, or record that is not yours or shared with you; introduce malware; or impose an unreasonable load on our infrastructure or that of our vendors.

1.10.7 Share or resell access. Share account credentials, sell, resell, sublicense, rent, lease, or provide the Service to third parties; create accounts by automated means; create multiple accounts to evade page limits, free-tier limits, or trial limits; or use the Service to provide a service to others for a fee. Care Team invitations under §8 are the only authorized way to give another person access.

1.10.8 Misrepresent our outputs. Present any BarkLens output as veterinary advice, as reviewed or approved by a veterinarian, as a diagnosis, or as clearance; remove or obscure source attributions, disclaimers, or provenance indicators; or republish library passages stripped of their citations.

1.10.9 Abuse, harass, or spam. Use referral, invitation, or waitlist features to send unsolicited messages; harvest addresses; or harass any person, including our staff and our reviewers.

1.10.10 Break the law. Use the Service in violation of any applicable federal, state, or local law, including veterinary-practice acts, consumer-protection statutes, and export-control and sanctions laws.

We may investigate suspected violations, and we may suspend or terminate access under §1.11 without prior notice where we reasonably believe there is a risk to users, animals, our systems, or our vendors. We may also preserve evidence of suspected misuse, restrict functionality while we investigate, and cooperate with lawful process. Keep independent copies of any original document you cannot afford to lose.

1.11 Your account, security, suspension, and termination

1.11.1 Credentials. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account, whether or not you authorized it. Notify us immediately at info@barklens.com if you suspect unauthorized access. Authentication is provided through our identity vendor (see §7). We may require additional protective authentication steps where we reasonably believe an account is at risk.

1.11.2 Accuracy. Keep your email address current. Notices to you are effective when sent to the address on file (see §1.20.5).

1.11.3 Your right to stop. You may stop using the Service, cancel a subscription (see §3.6), or close your account at any time. Closing your account does not automatically cancel a store-billed subscription; subscriptions are canceled through the app store that sold them, as described in §3.6.

1.11.4 Our right to suspend or terminate. We may suspend or terminate your access to all or part of the Service, with or without notice, if we reasonably believe you have violated these Terms, if your use creates legal risk or a risk of harm, if required by law or by an app store, if we discontinue the Service or a feature, or if payment for a paid plan fails or is reversed. Where we can do so consistent with law and safety, we will give notice and an opportunity to cure.

1.11.5 Effect of termination. On termination, your license to use the Service ends immediately. Your records remain yours. Consistent with §3.8, §3.9, and §6, you retain access to your stored records and to export for the period described in those sections, and you may request deletion at any time. Sections that by their nature should survive — including §1.7, §1.8, §1.12, §1.14, §1.15, §1.16, §1.17, §1.18, §1.19, and §1.20 — survive termination.

1.11.6 Discontinuation of the Service. If we decide to discontinue the Service entirely, we will make reasonable efforts to give at least thirty (30) days’ advance notice by email and in-app notice, and to keep export functionality available through the end of that period, so you can retrieve your records before shutdown.

1.12 Intellectual property; your content and the license you give us

1.12.1 Our property. The Service, including its software, design, user interface, text, graphics, the organization, selection, structure, curation, tagging, and arrangement of the veterinary source library, our internal doctrine, our scoring and provenance systems, and the BARKLENS and THINKTANC names and logos, is owned by us or our licensors and is protected by copyright, trademark, trade-secret, and other laws. Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the Service for your own personal, non-commercial use in caring for your own dogs. No other rights are granted.

1.12.2 Third-party source material. Passages quoted in the library remain the property of their publishers and are used with attribution for reference. You may use them for your own personal reference and may show them to your veterinarian. You may not republish them commercially or strip their attributions.

1.12.3 Your content stays yours. You retain all ownership of the records, documents, photographs, values, notes, questions, and other material you submit to the Service (“Your Content”). We claim no ownership of Your Content. You may export Your Content at any time, including after you cancel a paid plan and after you close your account, as described in §3.9 and §6. An export may not reproduce third-party library content beyond what the applicable publisher license permits.

1.12.4 The narrow license you grant us. You grant us a limited, worldwide, royalty-free, non-exclusive license to host, store, back up, transmit, reproduce, reformat, and process Your Content, and to create derived technical artifacts from it (for example, extracted text from a photograph and structured data fields derived from that text), solely for the following purposes: (a) providing, maintaining, and securing the Service for you; (b) producing answers, chart projections, exports, and other output for you and for the Care Team members you have authorized; (c) making backups and ensuring disaster recovery; (d) complying with law and enforcing these Terms; and (e) diagnosing and fixing errors reported by you or detected in your account. The license permits us to make Your Content available to the subprocessors listed in §7 that act for us under contractual restrictions, and you represent that you hold the rights necessary to grant it. It does not transfer ownership of Your Content to us, it does not authorize any sale of Your Content, and it does not authorize third-party model training. This license exists only to run the product for you. It ends when Your Content is deleted, except for copies retained in backups until they age out under §6 and copies we must keep by law.

1.12.5 What the license does not permit. For the avoidance of doubt, the license in §1.12.4 does not permit us to sell Your Content, to share Your Content with advertisers or data brokers, to publish Your Content, or to provide Your Content to any third party for that party’s own purposes. We do not sell or share personal information as those terms are used in state privacy laws (see §2.10). With respect to artificial-intelligence model providers, see §2.7 and §7: user content is transmitted to model providers only to produce output for you, and it is our position and contractual requirement that user content is not used to train third-party models.

1.12.6 Product improvement. We may use de-identified and aggregated information derived from use of the Service — for example, error rates in reading a class of document, retrieval quality metrics, and feature-usage counts — to improve accuracy, safety, and reliability. Where we would use identifiable content from your account for improvement beyond fixing a problem you reported, we will do so only with your consent, and you may withdraw that consent at any time.

1.12.7 Feedback. If you send us suggestions or feedback, you grant us an unrestricted, royalty-free right to use it without obligation or compensation. Please do not include confidential information in feedback.

1.12.8 Copyright complaints. If you believe material in the Service infringes your copyright, send a notice containing the elements required by 17 U.S.C. § 512(c)(3) to info@barklens.com and by mail to ThinkTanc LLC d/b/a BarkLens, 7804 Fairview Rd C-162, Charlotte, NC 28226.

1.13 Fees, plans, and subscriptions

Paid features are sold as auto-renewing subscriptions purchased through the Apple App Store or Google Play. Plan definitions, pricing, the free tier, the free trial, renewal, cancellation, refunds, price changes, and what happens after cancellation are set out in full in §3 (Subscription and Billing Terms), which is incorporated into these Terms. In summary: Plus is $14.95 per month or $149 per year for one dog; Family is $24.95 per month or $249 per year for up to four dogs; a free account may extract up to 125 pages within a 7-day window; billing, renewal, and refunds are governed by the store that sold the subscription; and your records and your ability to export them remain available to you free of charge after cancellation. Selecting a plan authorizes the store to charge you under the store’s terms. BarkLens does not control store billing, renewal processing, or refunds, and deleting the app, stopping use, or closing your BarkLens account does not cancel a store-billed subscription.

1.14 Disclaimers of warranty

1.14.1 As is. THE SERVICE, INCLUDING ALL CONTENT, CHART OUTPUT, ANSWERS, SOURCE PASSAGES, EXTRACTED VALUES, TRENDS, EXPORTS, NOTIFICATIONS, AND OTHER OUTPUT, IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND.

1.14.2 Disclaimed warranties. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY, AND OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, ACCURACY, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING, USAGE, OR TRADE PRACTICE.

1.14.3 Specific non-warranties. WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT: (a) the Service will be uninterrupted, secure, error-free, or available at any particular time; (b) any value extracted from any document is accurate, complete, correctly attributed, or associated with the correct dog; (c) any answer, passage, comparison, or trend is accurate, current, complete, or applicable to your dog; (d) the Service will detect, flag, surface, or alert you to any condition, error, interaction, omission, or risk; (e) any notification will be generated or delivered; (f) any chart is a complete or accurate medical history; (g) defects will be corrected; or (h) the Service will produce any particular health, behavioral, financial, or clinical outcome for your dog. NO STATEMENT BY US OR BY ANY EMPLOYEE, CONTRACTOR, REVIEWER, OR VENDOR CREATES A WARRANTY THAT IS NOT STATED IN THESE TERMS.

1.14.4 No medical or veterinary warranty. THE SERVICE IS NOT A MEDICAL OR VETERINARY SERVICE AND WE MAKE NO WARRANTY OF ANY KIND CONCERNING THE HEALTH, DIAGNOSIS, TREATMENT, PROGNOSIS, SAFETY, OR WELFARE OF ANY ANIMAL. No output of the Service is a substitute for examination, diagnosis, or treatment by a licensed veterinarian.

1.14.5 Statutory limits. Some states do not allow the exclusion of certain implied warranties, so some of the exclusions above may not apply to you. In that case, the disclaimers apply to the fullest extent permitted by the law of your state, and any warranty that cannot be disclaimed is limited in duration to the shortest period permitted by law.

1.15 Assumption of risk and your responsibility for your dog

You acknowledge and agree that you, together with the licensed veterinarian who cares for your dog, are solely responsible for every decision made about your dog’s health, care, feeding, medication, and treatment. You assume all risk arising from your use of the Service and from any decision you make with the Service in front of you, including the risk that the Service is wrong, incomplete, out of date, or silent when it should not be. You agree that you will not use the Service in place of veterinary examination, and that you will seek veterinary care promptly when your dog needs it, without regard to what the Service does or does not show.

1.16 Limitation of liability

1.16.1 Exclusion of indirect damages. TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER BARKLENS NOR ITS MEMBERS, MANAGERS, OFFICERS, EMPLOYEES, CONTRACTORS, ADVISORS, REVIEWERS, LICENSORS, OR VENDORS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR ANTICIPATED SAVINGS, OR FOR THE COST OF SUBSTITUTE SERVICES, VETERINARY EXPENSES, DIAGNOSTIC OR TREATMENT COSTS, EUTHANASIA OR CREMATION EXPENSES, LOSS OF OR HARM TO AN ANIMAL, OR EMOTIONAL DISTRESS OR LOSS OF COMPANIONSHIP, OR DAMAGES ARISING FROM DELAYED CARE, RELIANCE ON CONTENT, FAILURE TO SEND OR RECEIVE A MESSAGE, UNAUTHORIZED ACCESS, DATA LOSS, OR THIRD-PARTY CONDUCT, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, ON ANY THEORY OF LIABILITY (CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, STATUTE, OR OTHERWISE), EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND EVEN IF A LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

1.16.2 Aggregate cap. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS ($100) OR (B) THE TOTAL AMOUNT YOU ACTUALLY PAID TO US OR TO AN APP STORE FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM.

1.16.3 Basis of the bargain. The disclaimers in §1.14 and the limitations in this §1.16 are essential elements of the agreement between us and reflect a reasonable allocation of risk in a low-cost consumer information service that does not examine animals and does not deliver veterinary care. Without them, the Service would not be offered at these prices or at all.

1.16.4 Carve-outs and state law. NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT LAWFULLY BE EXCLUDED OR LIMITED, including, to the extent applicable, liability for our own fraud or fraudulent misrepresentation, for willful misconduct, for gross negligence where a limitation is unenforceable, for death or personal injury caused by our negligence, or for any liability under a statute that expressly prohibits limitation. Some states do not allow the exclusion or limitation of certain damages; in those states, our liability is limited to the smallest amount permitted by law. Applicable consumer law may give you rights that cannot be waived; where it does, this §1.16 applies only to the maximum extent that law permits.

1.16.5 Time limit. To the fullest extent permitted by law, any claim arising out of or relating to the Service or these Terms must be brought within one (1) year after the claim arises, or it is permanently barred.

1.17 Indemnification

You agree to defend, indemnify, and hold harmless BarkLens and its members, managers, officers, employees, contractors, advisors, reviewers, licensors, and vendors from and against all claims, demands, actions, proceedings, losses, liabilities, damages, penalties, fines, costs, and expenses (including reasonable attorneys’ fees) arising out of or relating to: (a) Your Content, including any claim that it infringes a third party’s rights or that it contains another person’s personal or health information uploaded in violation of §1.10.1; (b) your use of the Service, including any decision you or anyone else made about an animal with the Service in front of them; (c) your breach of these Terms or of any law; (d) your invitation of, sharing with, or conduct toward any Care Team member, and any Care Team member’s use of access you granted; (e) any representation you make to a third party about the Service, including presenting Service output as veterinary advice or as vet-reviewed; and (f) your use of the Service on behalf of any organization without authority. You are not required to indemnify us to the extent a claim arises from our own fraud, willful misconduct, or other conduct for which indemnification may not lawfully be required.

We may assume the exclusive defense and control of any matter subject to indemnification, at your expense, and you agree to cooperate. You will not settle any matter that imposes an obligation on us without our prior written consent.

1.18 Dispute resolution — arbitration agreement and class-action waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS. IT REQUIRES THAT MOST DISPUTES BETWEEN YOU AND BARKLENS BE RESOLVED BY BINDING INDIVIDUAL ARBITRATION RATHER THAN IN COURT, AND IT WAIVES YOUR RIGHT TO A JURY TRIAL AND YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION. YOU MAY OPT OUT OF THIS SECTION WITHIN THIRTY (30) DAYS, AS DESCRIBED IN §1.18.8.

1.18.1 Informal resolution first. Before starting an arbitration or a court proceeding, you and we agree to try to resolve the dispute informally. Send a written notice to info@barklens.com (or, if we are notifying you, to the email address on your account) describing the dispute. The notice must state the claimant’s name and contact information, the email address associated with the account, the facts and the legal basis of the dispute, the relief requested, and a good-faith calculation of any monetary demand. Notices to us must be sent to info@barklens.com and to the mailing address in §1.20.5, and we may send notice to the email or mailing address associated with your account. Both parties agree to negotiate in good faith for sixty (60) days from the date the notice is received. This informal-resolution period is a condition precedent to commencing arbitration, and any applicable limitations period is tolled while it runs.

1.18.2 Agreement to arbitrate. Except as provided in §1.18.5 and §1.18.8, you and BarkLens agree that any dispute, claim, or controversy arising out of or relating to the Service, these Terms, any incorporated policy, any communication we send you, or the relationship between us — including questions of the formation, scope, interpretation, enforceability, or breach of this arbitration agreement — will be resolved exclusively by final and binding individual arbitration, and not in a court, except that a court of competent jurisdiction will decide any dispute about the enforceability of the class-action waiver in §1.18.4.

1.18.3 Administration, rules, and seat. The arbitration will be administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules in effect when the arbitration is commenced, as modified by this section. The rules and filing forms are available at adr.org. The arbitration will be conducted by a single neutral arbitrator. The arbitration will be seated in the state where you reside, and you may elect to proceed by telephone, videoconference, or written submission, or in person in the county where you reside, unless you and we agree otherwise. The arbitrator may award any relief available in a court under applicable law to you individually, including statutory damages and attorneys’ fees where a statute provides for them, but may not award relief on behalf of anyone else. The arbitrator’s award may be entered as a judgment in any court of competent jurisdiction. The Federal Arbitration Act governs the interpretation and enforcement of this section. We will pay AAA filing, administrative, and arbitrator fees as required by the AAA Consumer Arbitration Rules, and we will pay more than the rules require where necessary for this section to be enforceable.

1.18.4 Class-action and class-arbitration waiver. YOU AND BARKLENS AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, MASS, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate the claims of more than one person and may not preside over any form of class or representative proceeding. If this waiver is held unenforceable as to a particular claim or a particular request for relief, that claim or request for relief will be severed and litigated in the courts specified in §1.19, and all other claims will proceed in arbitration. If a final judicial decision holds that applicable law prevents waiver of a particular claim or of a request for public injunctive relief, that claim or request will be severed and heard in a court of competent jurisdiction after all arbitrable claims have been resolved, and the remainder of this §1.18 remains enforceable.

1.18.5 Carve-outs. Notwithstanding §1.18.2: (a) either party may bring an individual claim in small-claims court in the county where you reside or in New Castle County, Delaware, if the claim qualifies and remains in that court on an individual basis; (b) either party may seek temporary or permanent injunctive or other equitable relief in the state or federal courts located in New Castle County, Delaware, to prevent or stop actual or threatened infringement, misappropriation, or violation of intellectual-property rights, unauthorized access to systems, or breach of §1.10; and (c) either party may bring an action to compel arbitration or to enforce an arbitration award. Seeking relief under this §1.18.5 does not waive either party’s right to arbitrate any other matter.

1.18.6 Jury-trial waiver. TO THE FULLEST EXTENT PERMITTED BY LAW, YOU AND BARKLENS EACH WAIVE ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, whether that proceeding arises under the carve-outs in §1.18.5 or because this arbitration agreement is held not to apply.

1.18.7 Confidentiality of the proceeding. Neither party will be required to keep the existence or outcome of an arbitration confidential, except that each party will protect the other’s confidential business information and any individual’s personal information consistent with applicable law and any protective order.

1.18.8 Your right to opt out of arbitration. You may reject this arbitration agreement, including the class-action waiver in §1.18.4, by sending written notice within thirty (30) days after you first accept these Terms. Send the notice by email to info@barklens.com with the subject line “Arbitration Opt-Out,” and include your full name, the email address associated with your account, and a clear statement that you decline arbitration. A timely opt-out is effective as to all claims and does not affect any other part of these Terms, and it will not affect your access to the Service or your subscription in any way. If you do not opt out within thirty (30) days, you and we are bound by this section.

1.18.9 Changes to this section. If we materially change this §1.18 after you accept these Terms, the change will not apply to any dispute of which we had actual notice before the change, and you may reject the change by notifying us at info@barklens.com within thirty (30) days of the change taking effect, in which case the version of §1.18 in force immediately before the change will continue to apply to you.

1.18.10 Survival. This §1.18 survives termination of these Terms and closure of your account.

1.19 Governing law and venue

These Terms and any dispute arising out of or relating to them or to the Service are governed by the laws of the State of Delaware, excluding its conflict-of-laws rules, and by the Federal Arbitration Act and other applicable federal law with respect to §1.18. For any claim not subject to arbitration — including claims brought under the carve-outs in §1.18.5(b) and (c), any claim severed under §1.18.4, and any claim if §1.18 is held unenforceable in its entirety — you and we consent to the exclusive jurisdiction and venue of the state and federal courts located in New Castle County, Delaware, and each party waives any objection to that venue and any claim of inconvenient forum. Nothing in this section deprives you of the protection of any mandatory consumer-protection law of your state of residence that applies notwithstanding a contractual choice of law.

1.20 General provisions

1.20.1 Changes to these Terms. We may modify these Terms. If a change is material, we will provide at least thirty (30) days’ advance notice by email to the address on your account and by in-app notice before the change takes effect, and we will update the “Effective” date and the revision history at the end of this document. Non-material changes (for example, clarifications, formatting, or contact-information updates) take effect when posted. Your continued use of the Service after a change takes effect constitutes acceptance of the changed Terms. If you do not accept a change, stop using the Service, cancel any subscription through the app store, and export your records. Changes to §1.18 are governed by §1.18.9. We will not apply a change retroactively to a dispute of which we had actual notice.

1.20.2 Changes to the Service. We may add, change, suspend, or remove features at any time. Where a change removes a feature that a paid plan materially depends on, we will give notice and, where required by law or by the app store, an opportunity to cancel.

1.20.3 Entire agreement. These Terms, together with the documents incorporated by reference in §1.1, are the entire agreement between you and us about the Service and supersede all prior or contemporaneous statements, marketing materials, beta communications, and understandings. No statement by any employee, contractor, reviewer, or advertisement modifies these Terms unless in a signed writing from an authorized officer of ThinkTanc LLC.

1.20.4 Assignment. You may not assign or transfer these Terms or your account, by operation of law or otherwise, without our prior written consent; any attempted assignment is void. We may assign these Terms in connection with a merger, acquisition, reorganization, financing, or sale of all or part of our assets, in which case we will provide notice as described in §2.5.4.

1.20.5 Notices. We may give notice to you by email to the address on your account, by in-app message, or by posting on the Service; notice is effective when sent or posted. You must give notice to us in writing by email to info@barklens.com, with a copy by mail to ThinkTanc LLC d/b/a BarkLens, 7804 Fairview Rd C-162, Charlotte, NC 28226. Notices to us are effective on receipt.

1.20.6 Severability. If any provision of these Terms is held invalid or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or if it cannot be modified, severed, and the remaining provisions will remain in full force. Severability within §1.18 is governed by §1.18.4.

1.20.7 No waiver. Our failure to enforce any provision is not a waiver of our right to enforce it later. A waiver is effective only if in writing and signed by an authorized officer.

1.20.8 No third-party beneficiaries. These Terms create no third-party beneficiary rights, except that Apple Inc. and Google LLC are third-party beneficiaries of §1.21 and of the corresponding provisions of §3, and may enforce them.

1.20.9 Relationship. Nothing in these Terms creates a partnership, joint venture, agency, employment, or fiduciary relationship between you and us. We are not your agent and we are not your veterinarian’s agent.

1.20.10 Force majeure. Neither party is liable for any delay or failure to perform caused by events beyond its reasonable control, including acts of God, natural disaster, epidemic, war, civil unrest, labor action, utility or network failure, vendor or cloud-provider outage, cyberattack, or governmental action. This does not excuse your payment obligations.

1.20.11 Headings and interpretation. Headings are for convenience only. “Including” means “including without limitation.” The Terms will not be construed against the drafter.

1.20.12 Export and sanctions. You represent that you are not located in, and are not a national of, any country or on any list that would make your use of the Service unlawful under U.S. export-control or sanctions laws.

1.20.13 Contact. Questions about these Terms: info@barklens.com. Privacy questions and rights requests: info@barklens.com. Mail: ThinkTanc LLC d/b/a BarkLens, 7804 Fairview Rd C-162, Charlotte, NC 28226.

1.21 App-store specific terms

1.21.1 Apple. If you obtained the app from the Apple App Store, you acknowledge that these Terms are between you and BarkLens only, not with Apple; that Apple has no obligation to furnish maintenance or support for the app; that in the event of any failure of the app to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price, if any, and to the maximum extent permitted by law Apple has no other warranty obligation with respect to the app; that Apple is not responsible for addressing any claim by you or a third party relating to the app, including product-liability, regulatory-compliance, and consumer-protection claims; that Apple is not responsible for the investigation, defense, settlement, or discharge of any third-party intellectual-property claim relating to the app; that you will comply with applicable third-party terms of service when using the app; and that Apple and its subsidiaries are third-party beneficiaries of this §1.21.1 and may enforce it against you.

1.21.2 Google. If you obtained the app from Google Play, your use is also subject to the Google Play Terms of Service, and Google is not a party to these Terms and has no responsibility for the app. Refunds and billing for purchases made through Google Play are governed by Google’s policies, as described in §3.7.

1.21.3 Store rules govern billing. All purchases, renewals, cancellations, and refunds for subscriptions sold through the App Store or Google Play are processed by, and governed by the policies of, the store that sold them. See §3.

3. Subscription and Billing Terms

Effective: September 16, 2026

These Subscription and Billing Terms are part of the Terms of Use at §1 and govern paid access to BarkLens.

3.1 Free tier

You may use BarkLens without paying. A free account may extract up to 125 pages within a rolling 7-day window. The limit is measured in pages, not documents: there is no cap on the number of documents, no per-document page cap, and no monthly allowance. When you reach the limit, extraction pauses until the window resets or you subscribe. Records you already have, and your ability to export them, remain available to you at no cost. We may apply reasonable technical rules to prevent duplicate, fraudulent, or abusive page processing.

3.2 Paid plans and prices

Plan	Dogs covered	Monthly price	Annual price
BarkLens Plus	1 dog	$14.95 / month	$149 / year
BarkLens Family	up to 4 dogs	$24.95 / month	$249 / year

Prices are in U.S. dollars and exclude any tax the app store collects. Paid plans unlock the premium features described in §3.8, including Ask, Care Team invitations, and connect-the-dots analysis across a dog’s records.

If you have more than four dogs, contact us at info@barklens.com.

Plan names describe software features only; they do not describe insurance or veterinary services. A Family plan does not create a shared legal account among household members — the subscribing account owner remains responsible for invitations and permissions under §8. The store purchase screen controls the plan, the billing period, the price, the trial, and the material limits of what you bought.

3.3 Free trial

A 7-day free trial is available to new subscribers. The trial gives you access to the features of the plan you selected. Unless you cancel before the trial ends, the trial converts automatically into a paid subscription for the plan and billing period you selected, and the app store charges your payment method at the then-current price. The store will tell you the price and the conversion date at purchase, and the trial’s end date is visible in your store subscription settings at any time. If you cancel during the trial, you keep access until the trial’s scheduled end date and are not charged. Only one trial per person or per store account; we and the stores may refuse a trial to anyone who has already had one. The store purchase screen and the store receipt state the authoritative trial end time, and repeated-trial abuse may result in suspension under §1.11.4.

3.4 Billing through the app stores

All subscriptions are sold as in-app purchases through the Apple App Store or Google Play. The store that sold your subscription processes your payment, stores your payment method, handles taxes, sends purchase receipts, applies its own currency and pricing rules, and manages renewal and cancellation. BarkLens does not receive, process, or store your payment card details. Your purchase is also governed by that store’s terms, and where its rules differ from these Terms with respect to payment, renewal, cancellation, or refunds, the store’s rules govern. You must maintain a valid store payment method; a failed or disputed charge may end paid access, and restoring a purchase requires the same store account.

3.5 Automatic renewal

Subscriptions renew automatically. A monthly subscription renews every month, and an annual subscription renews every year, on the anniversary of your purchase, at the then-current price, until you cancel. The store charges your payment method within 24 hours before the start of each new period, or on the schedule the store applies. You authorize that recurring charge when you subscribe.

Pre-renewal notice. Where required by law or by store policy, and as a matter of practice for annual plans, we will send an email reminder before an annual subscription renews, telling you the renewal date, the amount, and how to cancel. The stores also send their own renewal notices and receipts; those are outside our control. The store’s subscription settings and receipts control renewal status; the status shown inside the app may lag behind the store.

3.6 Cancellation

You may cancel at any time, and you cancel through the store that sold the subscription — in iOS Settings under your Apple Account subscriptions, or in the Google Play app under Payments and subscriptions. We cannot cancel a store-billed subscription for you. Cancellation stops future renewals; it does not shorten the period you already paid for, and your paid access continues to the end of that period. After that, your account moves to the free state described in §3.8. Deleting the app does not cancel a subscription, and closing your BarkLens account does not cancel a subscription — you must cancel with the store. Reinstalling the app does not reverse a cancellation, although restoring an active purchase may restore paid access.

3.7 Refunds

Refunds for purchases made through the App Store or Google Play are governed entirely by the policies of those stores, and we do not process refunds directly. To request one, use Apple’s “Report a Problem” process or Google Play’s refund request process. We may, at our discretion, advocate for a refund with the store on your behalf if you write to info@barklens.com describing the problem, but we cannot compel a store decision. Nothing in this section limits any non-waivable refund or cancellation right you have under the law of your state, including any statutory right to cancel within a stated period. Refunds, credits, billing disputes, and accidental-purchase requests are governed by Apple App Store or Google Play policy and must generally be submitted to the store; BarkLens does not promise and does not independently issue a refund for a store-managed transaction. If BarkLens receives a payment reversal or chargeback for a transaction, the paid entitlements associated with that transaction may be revoked.

3.8 What changes when a paid plan ends

When a paid plan ends — whether you cancel, the trial does not convert, payment fails, or the plan lapses:

What you keep, free of charge:

• Your records. Every document, photograph, extracted value, and chart entry stays in your account and remains viewable.
• Your chat and answer history. Retained and readable; we do not delete your history to pressure you into resubscribing.
• Export. Full export of your records at any time, in the formats described in §3.9.
• Your account. You keep it, and you may resubscribe at any time.

What turns off:

• Ask — asking new questions of the veterinary library.

• Care Team invitations — you cannot issue new invitations, and existing Care Team access is suspended.

• Connect-the-dots analysis — cross-record analysis, trend surfaces, and derived comparisons.

• Any other premium feature identified as such in the app and in the store listing at the time of purchase.

• New extraction beyond the free-tier limit — the 125-pages-per-7-days limit in §3.1 applies again.

3.9 Export, including after you leave

You own your records and you may take them with you. Export is available while your subscription is active, after cancellation, and after you close your account.

• Formats: PDF (human-readable), RTF (editable), and JSON (structured, machine-readable).
• Scope: your dog’s records, extracted values with their source attributions, chart sections, coverage statements, and — where the format supports it — the original uploaded images.
• After account closure: export remains available for ninety (90) days after closure, so that a decision made in a difficult moment is reversible. After that window, data is purged as described in §6, and we cannot recover it.
• No charge: we do not charge for export, and we do not degrade export as a retention tactic.
• Conditions: export remains subject to account security, lawful suspension, scheduled maintenance, format availability, reasonable identity verification, and the continued operation of the Service. Unlicensed third-party library content may be omitted from an export.

3.10 Price changes

We may change prices. We will give you at least thirty (30) days’ notice by email and in-app notice before a price change applies to your subscription, and the change will take effect only at the start of a renewal period. You may cancel before then, through the store, and the store’s own price-change consent rules also apply — in some cases a store will require your affirmative consent before charging a higher price, and if you do not consent your subscription may not renew. Founding-member pricing is locked as described in §4.6. Promotional prices apply only for the stated promotional period and revert to the standard price afterward, which we will tell you at purchase. We will not retroactively shorten a period you have already paid for. Remedies for a discontinued feature remain subject to applicable law and store policy.

3.11 Failed payments; taxes; other

If a payment fails, the store may retry, and premium features may pause until payment succeeds. Prices exclude taxes, which the store calculates and collects. If you dispute a charge with your card issuer rather than the store, we may suspend paid features while the dispute is pending. Plan changes (upgrade, downgrade, monthly to annual) are made through the store and take effect as the store’s rules provide.

---

---

4. Email and Waitlist Terms

Effective: September 16, 2026

These terms govern the BarkLens waitlist, our email communications, the founding-member offer, and referrals. Email is delivered by Mailgun on our behalf (see §7).

4.1 Two kinds of email, and the difference matters

4.1.1 Transactional and relationship email. If you have an account, we send messages necessary to the relationship: account confirmation and sign-in, security notices, trial-conversion and renewal notices, receipts and billing problems, Care Team invitations and revocation confirmations, export confirmations, service interruptions, and changes to these Terms or the Privacy Policy. These are not marketing messages, and the primary purpose of each is transactional or relationship-based, as CAN-SPAM uses those terms. You cannot unsubscribe from them while you hold an account, because they carry information you need. You can end them by closing your account.

4.1.2 Marketing email. Product news, launch announcements, founding-member offers, educational content, feature announcements, and promotions. We send these only if you asked for them, and you may unsubscribe at any time with one click. We do not send marketing email to anyone who has unsubscribed, and we do not resubscribe you because you later created an account, bought a subscription, or contacted support. If a form collects your address only to carry out a transaction — a password reset or a record export, for example — we do not treat that action alone as consent to unrelated marketing.

4.1.3 Hybrid messages are treated as marketing. If a message combines transactional content with promotional content, we treat it as marketing for compliance purposes: it carries the unsubscribe mechanism and the sender identification described below.

4.2 Consent — joining the waitlist and the welcome email

When you join the BarkLens waitlist on barklens.com, you give us your email address and you opt in to receive: (a) a welcome email confirming your sign-up; (b) launch and availability updates; and (c) the founding-member offer described in §4.6, if it is open. The opt-in is presented as an affirmative, unchecked action on the sign-up form, with plain text next to it describing what you will receive. We do not pre-check consent boxes, we do not bury consent in a privacy policy link, and we do not add anyone to the waitlist who did not enter their own address.

Consent records. For each sign-up we retain the email address, the date and time, the page or source, the IP address at sign-up, and the exact consent text displayed, so we can demonstrate consent later.

No purchased lists, no harvesting. We do not buy, rent, exchange, or harvest email addresses, and we do not use dictionary attacks or address generation. Every address in our system came from the person who owns it, or from an account owner who invited that person to a Care Team (§8).

4.3 Sender identification and honest headers

Every commercial email we send:

• identifies the sender as ThinkTanc LLC d/b/a BarkLens;
• uses accurate “From,” “Reply-To,” and routing information, and a From address at a domain we control;
• carries a subject line that is not deceptive and that accurately reflects the content of the message;
• clearly identifies the message as an advertisement where required; and
• includes our valid physical postal address: ThinkTanc LLC d/b/a BarkLens, 7804 Fairview Rd C-162, Charlotte, NC 28226.

The “From” name may display BarkLens, but the footer of every commercial message identifies the legal entity, ThinkTanc LLC d/b/a BarkLens. Mailgun sends waitlist, welcome, transactional, and permitted marketing email on our behalf, and we may use delivery, bounce, complaint, open, and click events to administer the list and evaluate our communications where that is permitted and disclosed. Email content is informational; it is not veterinary advice and it is not emergency monitoring.

4.4 Unsubscribe

Every marketing email includes a clear and conspicuous unsubscribe link in the footer and a one-click List-Unsubscribe header, both of which work without requiring you to log in, create an account, provide a reason, or take more than one step. Unsubscribing from marketing does not close your account and does not stop transactional messages under §4.1.1.

Timing. We process unsubscribes immediately in the ordinary course, and in every case within ten (10) business days of receipt, which is the outer limit CAN-SPAM allows. We also honor an unsubscribe request sent to info@barklens.com, or a reply asking to be removed, even if it does not use the link.

Preference options. Where we offer topic-level preferences (for example, product news but not educational content), a global unsubscribe is always presented alongside them and always available. A preference center never replaces the one-click opt-out. We may also stop sending to an address that repeatedly bounces or generates spam complaints.

4.5 Suppression records

When you unsubscribe, we add your address to a suppression list that we retain indefinitely. We keep it for one reason: so that we can continue to honor your unsubscribe, including after a database migration, a change of email vendor, or a new campaign. A suppression record is used only to prevent email — never to market to you, never to profile you, and never for any other purpose. We do not delete a suppression record on a deletion request unless you ask us specifically to remove your address from the suppression list, which we will explain carries the risk that a later sign-up or import could email you again. See §6.

4.6 Founding-member offer

If we make a founding-member offer to waitlist subscribers, these terms apply, subject to the specific offer text presented at the time:

4.6.1 What it is. Early access to the app before general availability, and a locked subscription price for twelve (12) months from the start of the first paid term — meaning that a general price increase under §3.10 will not apply to a founding member during those twelve months.

4.6.2 Conditions. The offer is available to waitlist subscribers who enroll during the stated offer window, is limited to the number of memberships stated in the offer, requires an active paid subscription purchased through an app store, and applies to the plan selected at enrollment.

4.6.3 What happens after twelve months. At the end of the lock period, the subscription renews at the then-current standard price for the plan, and we will give the notice required by §3.10 before that happens.

4.6.4 Lapse and plan changes. The founding-member price is lost if the subscription lapses. During the original twelve-month lock period, a change between Plus and Family or between monthly and annual billing preserves the equivalent founding-member discount where the app store permits it.

4.6.5 Transferability. The founding-member benefit is personal and non-transferable. It cannot be sold, assigned, or moved to another person or store account.

4.6.6 Our rights. We may modify or end the offer prospectively at any time before you enroll, and we may revoke a benefit obtained through fraud, multiple accounts, or violation of §1.10. Void where prohibited. The offer is not a lifetime price guarantee, and it is not a warranty about future features. Acceptance occurs only when an eligible person completes the stated store purchase or redemption process; joining the waitlist alone does not guarantee price, availability, or membership. Any benefit described as “lifetime” must define its duration, the product it attaches to, the account continuity it requires, and what happens if the Service is discontinued, and no offer may imply a health outcome, emergency review, or veterinary care.

4.7 Referrals and invitations

4.7.1 Referral rewards. A reward is earned only when the qualifying event actually occurs, is void if the underlying subscription is refunded, canceled during a trial, or reversed, has no cash value unless the offer says otherwise, and may not be sold or transferred. A referrer who promotes BarkLens publicly must clearly and conspicuously disclose any material reward. A reward is not payment for health information, and it does not entitle the referrer to access the referred person’s account or records. We may deny a reward for self-referral, duplicate accounts, returns, chargebacks, manipulation, or fraud.

4.7.2 Anti-spam rules for referrals and Care Team invitations. When you invite someone — as a referral or to a Care Team under §8 — you must have a personal relationship with that person and a reasonable basis to believe they want to hear from you. You may not: post referral links to unrelated forums, comment sections, coupon sites, or social feeds in a way that constitutes spam; send bulk or automated invitations; use purchased lists or harvested addresses; misrepresent yourself as BarkLens or imply that we endorse your message; use paid search or advertising on our name or trademarks to distribute referral links; or invite anyone who has asked you or us to stop. We send one invitation email per invitation and, where applicable, at most one reminder; we do not send unsolicited follow-up campaigns to invited addresses who never accept, and an invited person may decline and be suppressed from further invitation email.

4.7.3 Enforcement. We may void rewards, disable referral links, and suspend accounts for violations of §4.7.2, and we may report abuse to the relevant platform.

4.7.4 Care Team invitation messages, and SMS. When an account owner directs us to invite someone to a Care Team, the owner represents that the owner has a lawful basis to give us the recipient’s contact information and reasonably believes the invitation is welcome. We use that contact information only to send the invitation, a limited reminder, security notices, and acceptance status; an invitation does not enroll the recipient in marketing email. The recipient may decline, ask for no further invitations, and report abuse to info@barklens.com. Invitation messages may not harass a recipient and must not disclose sensitive facts about a dog or an owner in preview text.

4.8 Deliverability and third-party mail systems

Email depends on systems we do not control. We do not guarantee that any email will be delivered, delivered on time, or land in your inbox rather than a spam folder. Do not rely on our email for anything time-critical about your dog’s health; see §1.6.2.

8. Care Team Sharing Terms

Effective: September 16, 2026 These terms are part of the Terms of Use (§1.9) and the Privacy Policy (§2.5.2).

8.1 What Care Team is

Care Team lets an account owner give specific people access to a specific dog’s record. It exists because dogs are cared for by more than one person — a spouse or partner, an adult child, a co-owner, a sitter or walker, a rescue coordinator, or a veterinary practice preparing for a visit. Care Team is not a social feature and it is not public. Nothing in a BarkLens account is visible to anyone the owner has not invited.

Only an account owner may invite a Care Team member, and the owner selects the access the member receives from the permissions the product presents. Access is personal to the invited recipient and may not be shared, reassigned, or exercised through another person’s credentials. BarkLens does not verify a family relationship, ownership of a dog, veterinary employment, or legal authority from the fact of an invitation, and BarkLens may freeze sharing that is disputed, insecure, or unlawful.

8.2 What an invited person can see and do

8.2.1 Access is owner-selected and scoped. When you invite someone, you choose what they can see from the options the app provides, which may include: the dog’s records and uploaded documents; specific chart sections such as instructions in force, allergies and adverse reactions, or the changed-and-open items; and the question-and-answer history for that dog. The interface should state the effective permission level on screen before a member gains access. Shared records may incidentally reveal information about the owner, the clinic, or a third party; redact unrelated information before sharing, and note that BarkLens conceals content only where an express redaction feature does so.

8.2.2 What they can add. If you grant contribution rights, an invited person may be able to upload documents, record observations, and confirm suggested values (for example, confirming a stool score) for that dog. Anything they add is attributed to them in the record, so the chart shows who asserted what and when. We do not verify anything a Care Team member adds. A contribution can be wrong, and a wrong contribution can propagate into what the chart shows and what an answer is built on. Each addition or confirmation identifies the contributing member and the time, and a member’s entry is that person’s report — it is not a veterinarian’s instruction and it is not a BarkLens clinical finding. A member may not overwrite provenance, alter an original document, impersonate the owner or a veterinarian, or use the chart to originate a medication dose, interval, or schedule. Where feasible the product records a correction as an appended entry, so that an original statement and the entry that superseded it both remain traceable.

8.2.3 What they cannot do. Unless you grant it, an invited person cannot change your account settings, manage your subscription, invite other people, remove other members, delete the dog, or see other dogs in a Family plan that you did not share.

8.2.4 Premium dependency. Care Team invitations are a premium feature. See §3.8 for what happens to Care Team access when a paid plan ends.

8.3 The account owner is responsible

8.3.1 You are the controller of your sharing. As between you and us, you decide who sees your dog’s record, and you are responsible for that decision. We provide the mechanism; we do not choose the people, we do not screen them, we do not verify their identity or credentials, and we do not supervise what they do with what they see.

8.3.2 Your representations. By inviting someone, you represent that you have the authority to share the dog’s record; that you have a legitimate reason to share it with that person; that the email address you entered belongs to the person you intend to invite; and that you are not sharing another person’s personal information in violation of §1.10.1 — remember that clinic paperwork often carries your name, address, and phone number, and sharing a record shares those too.

8.3.3 Indemnity. §1.17(d) applies: you are responsible for claims arising from your invitations, from a Care Team member’s use of the access you granted, and from anything a Care Team member adds to the record.

8.3.4 If you are the invited person. Access you receive is granted by the owner and is limited to what the owner selected. You must use it only to help care for that dog, you must not copy, export, publish, or repurpose the record for any other reason, and you are bound by the Terms of Use — including the six limits in §1.5, the emergency warning, and the acceptable-use rules in §1.10 — when you use it. You are not the account owner and you cannot control retention or deletion; if you want your own contributions removed, ask the owner or write to info@barklens.com. You may use shared information only as the owner authorized, and you must protect it: no public posting, no sale, no profiling, no employment or insurance use, no use to train a model, and no disclosure to anyone the owner did not authorize. Accepting access does not create a duty on BarkLens or on you to monitor the dog. If you become aware of a possible emergency, contact a veterinarian or an emergency animal hospital immediately, and do not assume that BarkLens will alert anyone.

8.4 Removing access

You may remove any Care Team member at any time, for any reason, without notice to them. Removal takes effect immediately: the member’s access to the dog’s record ends, pending invitations can be canceled, and the revocation is recorded with a timestamp in the account’s access log. You may also change a member’s permissions at any time without removing them, and you may re-invite someone you removed. A member may also remove themselves.

We may suspend or remove Care Team access ourselves, without notice, where we reasonably believe access is being used in violation of §1.10 or presents a security risk.

8.5 What removal cannot undo

This is the most important paragraph in this section, and it is stated plainly because the alternative is a false sense of control.

Removing a Care Team member ends their future access. It does not un-see what they have already seen. A person who had access may have read the record, remembered it, taken notes, taken screenshots, photographed the screen, exported files, printed pages, or forwarded material to someone else. We can revoke access. We cannot revoke memory, and we cannot retrieve, delete, or track copies that left the Service. BarkLens has no ability to reach into another person’s device, notes, email, or files, and no ability to know that a copy exists.

The practical consequences you accept when you invite someone:

• Assume permanence. Anything you share should be information you are prepared for that person to know indefinitely.
• Scope narrowly, and re-scope early. Grant the least access that lets the person help, and adjust permissions as soon as their role changes rather than at the end of a dispute.
• Removal is prospective only. It is a stop, not a rewind.
• Deletion has the same limit. If you delete a record, it is removed from the Service and from what any member can see going forward, but a copy a member already exported is not reachable by our deletion process (see §6.2.5).
• We will help where we can. If you believe a former member is misusing exported material, contact info@barklens.com; we will provide the access-log information we hold, to the extent we lawfully can, but the dispute is between you and that person.

8.6 Changes, cancellation, and account closure

An account owner may change or withdraw a member’s access at any time while the account is active. Cancellation of a paid plan ends the ability to issue new Care Team invitations at the end of the paid entitlement and may change the access of existing members as described in §3.8. Closure of the account terminates in-product Care Team access when the closure takes effect, subject to the grace period in §6.1 and to our security controls. A member who needs an authorized copy of something should export it before access ends, and closure of the owner’s account does not reach a copy a member has already taken outside the Service.
