The essentials
Shadow Trainer is designed to work on your phone. Your streak, training sessions and record are stored locally on your device.
Training data
Estimated calories, counted punches and your progress are computed and stored on your device. We do not collect or sell them.
No account, no server
The app has no accounts and no sign-in, and uploads nothing to any server. Everything lives on your phone; if you delete the app, that data goes with it. You can erase it beforehand from Profile → Delete my data.
Purchases
Payments are processed by Apple. We use RevenueCat to validate your purchase; RevenueCat receives an anonymous transaction identifier, never your card or identity.
Usage statistics
We log anonymous usage events (e.g. "completed a session") to improve the app. No advertising, no cross-app tracking (no ATT, no IDFA).
