Live sensor samples
Accelerometer and gyroscope samples are processed in memory during a session and are not persisted.
Privacy boundary
What stays on your device?
Wrist Trainer treats offline training as the default. Here is the boundary between live samples, local summaries, and optional account features.
Three layers
Know what is processed, and what is not.
Local session summaries
Times, targets, direction counts, and maximum estimates stay on the device, with up to 100 summaries.
Account and membership
Core training works without sign-in. If you choose to sign in, Wrist handles identity, sessions, and entitlement checks.
Outside the purchase path
Training is not a purchase attribute.
Training, sensor, angle, count, target, theme, and language data are not sent as RevenueCat or Google Play purchase attributes.
- No raw training video upload. The app does not use camera, microphone, or cloud workout video sync.
- No training data sent to the store. Google Play handles products and checkout only.
- Sign-in is not purchase. Sign-in establishes an app account; membership is selected and verified separately.
- Local deletion is available. Deleting local records does not delete Google Play or RevenueCat transaction history.
