Privacy Policy

Last updated: March 29, 2026

Calibro is a calisthenics training tracker for iOS and Apple Watch. Your privacy is important to us. This policy explains what data the app collects, how it is stored, and your rights.

Data Storage

All your workout data, exercise progression, and settings are stored locally on your device using an on-device database. No data is sent to external servers. The app does not use user accounts or authentication.

Data Deletion

You can permanently delete all your data at any time from within the app:

Profile → Delete All Data

Confirming this action will erase the following from your device:

• All workout sessions and exercise logs
• All exercise progression levels (your current level for each exercise)
• All personal records
• All app preferences and settings (rest pace, weekly goal, travel mode, onboarding state)

Built-in exercise definitions and progression ladders (the catalog of movements the app ships with) are not personal data and are kept so the app remains usable. They will remain available exactly as they appear on a fresh install.

Once deleted, your data cannot be recovered. Because nothing is stored remotely, you do not need to make any further request to us. The deletion is final and complete as soon as you confirm it.

If you would prefer to remove the app entirely, you can uninstall Calibro using iOS's standard app deletion. This removes the entire local database and has the same effect as Delete All Data.

Apple Health (HealthKit)

The Apple Watch companion app can read heart rate data during workouts and write workout sessions to Apple Health. This data stays on your device and in Apple Health. It is never transmitted to us or any third party. You can revoke HealthKit access at any time in Settings > Health > Data Access.

Backup & Restore

The app offers a manual backup and restore feature that exports your data as a JSON file to a location you choose on your device. No cloud sync or automatic uploads occur.

Analytics & Tracking

Calibro does not use tracking frameworks, advertising identifiers, or cross-app tracking. We do not collect analytics data.

Third-Party Services

Calibro does not currently use any third-party services that collect user data. If this changes in the future, this policy will be updated accordingly.

Children's Privacy

Calibro does not knowingly collect personal information from children under 13. The app does not require personal information to function.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated date.
