Privacy Policy

Last updated: 13 July 2026

Tavi ("we", "our") is a pet-health tracking app for dogs and cats. This policy explains what we collect, why, and your choices. Tavi is offline-first: your data lives on your device by default, and cloud features are optional.

Data you provide

Pet information — names, species, breed, dates, weight, medications, vaccinations, vet visits, symptoms, notes, photos and documents you add.
Account (optional) — if you sign in for cloud sync, your email address (via email/password or Google Sign-In).

How your data is stored

On your device — all records are stored locally (SQLite) and work fully offline. This is the source of truth.
Cloud sync (optional) — if you sign in, your records are synced to our backend (hosted in the US on Railway, with a MongoDB Atlas database) so they're available across your devices and restorable. Every request is authenticated and scoped to your account, so you can only access your own records.
Photos & documents — files you attach are stored on Amazon S3 via short-lived signed URLs, referenced only by your account.

AI features

AI insights, the symptom checker, breed guidance and document scanning are processed by Anthropic's Claude via our secure server function. We send only the pet-health context needed (e.g. species, age, weights, the text/photo you submit) — never your name, email or device identifiers. AI output is informational only and is not veterinary advice.

What we do not do

We do not sell your data.
We do not use your data for advertising, and the app contains no ad tracking.

Third-party services

We rely on: Railway (application hosting), MongoDB Atlas (database), Amazon Web Services (S3) (file storage), Anthropic (AI processing), Google Sign-In (optional login), and the Apple App Store / Google Play (purchases). Each processes data under its own terms.

Payments

Premium subscriptions are handled entirely by Apple or Google. We never receive or store your payment-card details.

Data retention & deletion

Local data remains until you delete it or uninstall the app. If you use cloud sync, you can delete your account and all associated cloud data at any time — see Delete your account. Deleting your account removes your pets, records, files and profile from our backend.

Your rights

You can access, export (PDF/JSON), correct, or delete your data from within the app. For any request, contact us below.

Children

Tavi is not directed to children under 13 and we do not knowingly collect their data.

Changes

We'll update this page and the "last updated" date when this policy changes.
