Draft, under legal review
Consumer Health Data Policy
Last updated: 28 September 2026
Some US states, including Washington (the My Health My Data Act) and Nevada, give extra protection to health data. This policy says what health data Tartaris collects, why, who it goes to, and what you can do about it. It adds to our Privacy Policy.
What we collect
- Training: lifts, sets, weights, reps, effort (RPE), workouts and notes.
- Body: body weight readings and the scoring category you choose.
- Food: what you eat, calories and macros, and meal photos you send for an estimate (not stored by us).
- Activity and recovery, if you connect Apple Health: daily steps are stored; sleep, resting heart rate and heart rate variability stay on your phone and never reach us.
- What we work out from it: estimated maxes, predictions, streaks and badges.
We collect it from you, and from Apple Health only if you connect it.
Why
Only to run Tartaris for you: to show your training back to you, estimate your strength, track food and body weight, and share what you choose with your followers and coach. We don't use it for advertising, and we never sell it.
Who receives it
- Supabase, which stores it for us.
- Anthropic, which receives the food description or photo you send for an estimate, only if you've allowed AI estimates.
- Your coach, who can see your training log and body weight while you have one.
- Other users, who see only what you choose to share: posts, your best lifts on leaderboards, and badges you show.
Crash reports go to Sentry, our crash-reporting service. They are not meant to carry any of the above: the app strips health readings, meals and food photos out of them before they leave your phone (see the Privacy Policy).
Your consent
We ask for your consent in the app before collecting any of it. You can withdraw it at any time by deleting your account in Settings › Account, which deletes the data permanently. You can also turn AI estimates off separately in Settings › Privacy & data.
Your rights
You can see and export your data (Settings › Account › Export my data), correct anything you've logged, and delete it. For anything else, or to appeal a decision we make about a request, email us and we'll answer within 45 days.
