What we store

Your account: your email address and password. It’s a Ken’s Toolbox account, the same sign-in as Broadser and the other Ken’s Toolbox products; the password is kept by our account provider (Supabase Auth) only as a one-way hash, and we can’t read it.
Your training: the plan you chose and your changes to it, weight / reps / RIR / time for each set, when workouts start and end, skipped or swapped exercises, and each exercise’s current working weight.
Your settings: language, weight unit, theme, and your setup answers (experience, goal, days per week, equipment).
Optional body-weight entries: saved only when you enter them.

We don’t ask for height, body weight, medical history or other health information, and the web app doesn’t read Apple Health or any other health platform.
We don’t show ads, sell or share your data, or run third-party analytics or tracking scripts.

Not signed in: only in this browser’s local storage on this device. Clearing the browser’s data removes it.
Signed in: with your account (a Supabase-hosted database), with a copy in your browser for offline use. Database access rules let each account read and write only its own records.
Netlify hosts the site, and the typeface loads from Google Fonts; those services see your IP address.
Your sign-in is kept in the browser’s local storage and in a cookie for this site, to keep you signed in on this device.

Signing out first syncs this device’s workouts to your account, then removes training data from the device, so the next person using it can’t see your records.
Workouts logged on a device before you sign in are never merged automatically — you’re asked whether to add them to your account.

Settings → Data: export a full backup (a JSON file) at any time, or clear this device.
Deleting training data: signed in, choose Settings → Data → Delete my training data. It’s removed from your account and this device right away.
Deleting the Ken’s Toolbox account itself (shared with Broadser and others): send us a message from the help page with your account email.

If this policy changes in a meaningful way, the date at the top of this page changes too.
