Terms & Conditions — Libtail

Effective date: 2026-11-05

These Terms & Conditions (“Terms”) govern your use of Libtail (the “App”), operated by Mariusz Uziębło (“we”, “us”, “our”). By using the App you agree to these Terms. If you do not agree, do not use the App.

How we handle your personal data is described in our Privacy Policy: https://twelveappschallenge-platform.web.app/legal/a3c3c68a-25a3-47d4-ae38-0071faaa20e6/privacy-policy

1. What Libtail is

Libtail is a health record for dogs and cats. You add photos or PDFs of vet documents, the App suggests structured entries, and after you approve them they are kept on your pet’s timeline together with the source document. The App also keeps lab results with the lab’s reference ranges, vaccinations and reminders, planned visits, an emergency card, a PDF report for your vet and, with Pro, shared care, medications and symptom notes.

2. Not veterinary advice

Libtail is a record keeper, not a vet. It does not diagnose, does not suggest or assess treatment and never calculates or sets doses. Marking a value as outside the range only compares it with the range printed on your own lab report; it is not a medical assessment. Charts and symptom summaries only show your own records.

Always ask a veterinarian about your pet’s health, treatment and medication. In an emergency, contact a vet or an emergency clinic straight away.

3. AI document reading

Documents are read by AI (Google Gemini) only after you give your consent in the App. AI can misread a document or miss information. Every suggested entry has to be checked and approved by you, and uncertain fields are marked. You are responsible for checking that the entries you approve match the original document. Keep the original documents; the App is not a substitute for them.

4. Who can use the App

You must be at least 18 years old. You may use the App only for your own pets or pets you care for, and only for lawful purposes.

5. Accounts

• Guest. You can use the App without an email address. A guest account cannot be recovered after you sign out, uninstall the App or lose your phone. Save your account with your email in the Profile to keep your data.
• Registered account. You sign in with a one-time code sent to your email. Keep access to your email secure; anyone who can read your email can sign in to your account.
• Signing in to another account from a guest account switches accounts; it does not merge their data.

6. Free features and Libtail Pro

The core of the App is free, within limits shown in the App (for example the number of documents and pets). Libtail Pro removes these limits and adds features such as lab trends, the full vet report, dark mode, shared care, medications with dose reminders and symptom notes. The current list is shown in the App before you buy.

• Pro is available only to registered accounts.
• Pro is an auto-renewing subscription, monthly or yearly, bought through the App Store or Google Play. The price is shown before you confirm the purchase and is charged to your store account.
• The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. You can manage or cancel it in your App Store or Google Play account settings. Deleting the App or your account does not cancel it.
• Payments, refunds and billing questions are handled by Apple or Google under their terms.
• When Pro ends, your data stays. You can still read and edit it, but adding new items returns to the free limits and Pro features are locked again.
• Your statutory consumer rights are not affected.

7. Shared care (Pro)

• Only the owner of a pet can invite other people to its record: up to 3 co-owners and 1 pet sitter at a time, including pending invites. The person invited needs a registered Libtail account and the one-time code sent to their email.
• Co-owners can view, add and edit entries in the record. A pet sitter can only read it, and only until the date the owner chose.
• Everyone with access sees the pet’s record, the first name and email address of the other caregivers, and who saved each dose.
• On a shared pet the owner’s Pro status and limits apply.
• The owner can remove access at any time, and any caregiver can leave. If the owner deletes the pet or their account, the pet’s record is deleted for everyone.
• Invite only people you trust and share only what you have the right to share.

8. Your content

Everything you add stays yours. You give us a limited licence to store, process and display it only to provide the App to you: to keep it, to show it to the people you share a pet with, and, with your consent, to send documents to our AI provider for reading. You confirm that you have the right to add the documents and photos you upload.

You agree not to upload content that is unlawful, that infringes other people’s rights, or that contains malware, and not to try to access other users’ data, overload or attack the service, or misuse invites.

9. Reminders and availability

Reminders are notifications scheduled on your phone. They can be delayed or blocked by your device settings, battery saving, a disabled permission or the time zone. Do not rely on the App as the only reminder for giving medication or for vaccinations.

We work to keep the App available and your data safe, but we cannot guarantee that it will always work without interruptions or errors. Some features need an internet connection. You can export a PDF report of your records at any time.

10. Intellectual property

The App, its design, code and content provided by us belong to Mariusz Uziębło and are protected by law. You may not copy, modify, distribute or reverse-engineer the App, except where the law allows it.

11. Liability

The App is provided “as is”. To the extent permitted by law, we are not liable for indirect damages, lost profits or decisions about your pet’s health or treatment made on the basis of entries in the App. Nothing in these Terms limits liability that cannot be limited by law, in particular liability for intentional harm or gross negligence, or your rights as a consumer.

12. Ending the agreement

You can stop using the App and delete your account at any time in Profile → Delete account. We may suspend or close an account that seriously breaches these Terms, for example by attacking the service or misusing other people’s data. Where possible, we will warn you first.

13. App Store

If you downloaded the App from the App Store, Apple’s Standard Licensed Application End User License Agreement also applies (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). Apple is not responsible for the App or its support.

14. Changes to these Terms

We may update these Terms when the App or the law changes. We will change the effective date above, and we will mention significant changes in the release notes of the App in the App Store and Google Play. If you continue to use the App after the change, the new Terms apply; if you do not agree, you can delete your account.

15. Governing law

These Terms are governed by Polish law. If you are a consumer, you keep the protection of the mandatory laws of the country where you live, and you can bring a claim in the courts there.
