Tally Mark beta · last updated November 9, 2026
Tally Mark is a calorie and workout tracker. This page says what it stores, where, and how to get rid of it. It is written for the beta and will be updated before the public launch.
What we store
- Account: your email address and a password (stored hashed; we never see it).
- Profile: what you enter at sign-up: goal, sex, age, height, weight, goal weight, activity level, and the calorie and protein targets worked out from them.
- Logs: the foods and numbers you log, your saved usual foods, your workout sets and weights, your log book, and any custom plan you build.
- Feedback: anything you send through the feedback box, with your browser type and screen size.
We do not use advertising trackers or analytics cookies in the beta. The only thing kept in your browser is your sign-in session and two display settings.
Photos and questions you send to the AI
When you look up a food, attach a label photo, or ask the coach a question, that text or photo is sent to Anthropic's Claude API to produce the answer. Coach questions include that day's log, your targets and your usual foods so the answer fits you. We do not keep the photos. Do not send anything you would not want processed this way.

Deleting your data
In the app, open Account & feedback and choose Delete all my data. That erases your profile and every log immediately. To have the account itself removed, email us from the address you signed up with.
Not medical advice
Calorie targets and coach answers are estimates for general fitness. They are not medical or dietary advice. Talk to a doctor before a big change in diet or training, especially with a health condition.
