Privacy policy

Last updated 2026-10-28

Keel is a personal project, run by one person and offered to a small group of invited people. This page says what Keel stores about you, where it goes and how to remove it.

What Keel stores

• Your account: the name and email address of the Google (or Apple) account you sign in with.
• What you enter: your training program, the sets you log, check-ins, body measurements, meals, targets and the messages and voice notes you send the coach.
• Photos you choose to add: meal photos and check-in progress photos. Progress photos are kept in private storage that only your account can read.
• Health data you connect: with your permission, read-only activity, exercise, sleep, heart-rate and body measurements from Google Health, and body measurements from Withings. You can disconnect either one at any time in the app.

How it's used

Only to run Keel for you: to show your plan and progress, to log what you eat and lift, and to let the coach suggest changes that you review first. Keel does not sell your data, show ads, or use advertising or analytics trackers.

Who processes it

• Supabase hosts Keel's database, file storage and sign-in.
• Keel's own server. The coach runs an open-weight language model on a computer operated by Keel, not on a third-party AI service.
• TypeSafe runs Keel's structured decisions, for example which of your usual meals a description matches or how a program change should be applied. It receives the text needed for the decision, which may include a meal photo.
• Langfuse stores traces of coach and meal-logging steps, including the content of those messages. They're used only to find and fix mistakes.
• Google and Withings send the health data you connect. Apple may process voice notes when iOS turns them into text.
• Claude (Anthropic), if you add the Keel connector to Claude. Claude reads and updates your Keel data through it when you ask, and Anthropic handles your Claude conversations under its own privacy policy.

Google user data

Keel's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google Health data is used only to provide Keel's features to you. It is never used for advertising or sold, and people read it only with your permission, for security, or where the law requires.

Keeping and deleting

Your data is kept while you have an account. To delete everything, use You → Delete account in the app, or write to ymendesf@gmail.com. Your account and data, including photos and stored connections to Google Health and Withings, are removed within 30 days. Disconnecting Google Health or Withings in the app stops new data from arriving and revokes Keel's access.

Security

Data travels over encrypted connections. Connection credentials for Google Health and Withings are stored encrypted, and every row in the database is readable only by its own account.

Children

Keel is not meant for anyone under 18.

Changes and contact

If this policy changes in a way that matters, the date above changes and you'll be told in the app or directly. For questions, write to ymendesf@gmail.com.
