Privacy policy
Last updated: October 20, 2026
Jimzo is a workout tracker made by Pierre Mouchan. It works without an account and without an internet connection.
Data Jimzo collects
None. Jimzo has no server, no analytics, no advertising, and no third-party SDKs. The developer cannot see your workouts, your settings, or how you use the app.
Data stored on your iPhone
Your workouts, sets, exercises, and settings stay on your iPhone, in the app’s private storage. Deleting Jimzo deletes them; workouts already saved to Apple Health stay there.
Apple Health
If you allow it, Jimzo saves each finished workout to Apple Health and runs a Health workout session while you train, so the rest timer keeps running when your iPhone is locked. Jimzo writes workouts only; it does not read any data from Health. You can change this permission at any time in the Health app, under Profile > Apps > Jimzo. Data from Health is never used for advertising and never shared with anyone.
Backups
You can export your workouts as a file and import it later. Jimzo creates the file only when you ask for it, and you choose where it goes (for example Files or iCloud Drive). The developer never receives it.
Support form
The Support tab opens a form hosted by Tally (tally.so) in your browser. Only what you choose to type there is sent, to Tally, under Tally’s privacy policy. The developer uses it only to answer you and improve Jimzo.
Children
Jimzo does not collect data from anyone, including children.
Changes
If this policy changes, the new version will be published at this address with a new date.
