Track is a personal calorie and macro tracker. This page describes what happens to your data when you use the app.

What stays on your phone

• Your profile (name, height, weight, age, sex, activity).
• Daily food log entries and the photos you took of food packages.
• Your goals, notes, and coach chat history.

All of this is stored in a local SQLite database on your device. None of it is sent to a server we control, and there is no account system. If you delete the app, the data is gone.

What is sent off-device

• Photos of food packages and nutrition labels are sent to Anthropic’s API for parsing into structured macros. Anthropic processes these images to return text/JSON; per their policy, API inputs are not used to train models. Photos are not retained beyond the request.
• Coach prompts (your message plus a short context block — recent log totals, current goals) are sent to Anthropic for the chat response.
• Goal recommendations and insights send a small JSON snapshot of your profile and recent logs to Anthropic.

Calls to Anthropic are proxied through a small Cloudflare Worker we host so the API key never lives on your device. The Worker logs request counts (for rate limiting) but not the content of your photos or messages.

Crash reporting (beta only)

The TestFlight beta build includes Sentry to capture crashes and JavaScript errors. Sentry receives stack traces, device model, OS version, and a synthetic install ID — no profile fields, photos, or chat content. The public 1.0 release will not include Sentry.

Third parties

• Anthropic — image parsing, coach, recommendations.
• Cloudflare — Worker hosting, KV (rate-limit counters and per-tester access codes).
• Sentry — crash reporting in the TestFlight beta only.

Your controls

• Export: You tab → Export CSV writes your full food log to a file you can save or share.
• Delete: You tab → Reset all data wipes the local database and cached photos.
• Revoke server access: Tell me and I’ll revoke your access code on the Worker; the app will stop being able to call the AI features.
