Stays on your iPhone
- Head movement from your AirPods. It's read on your iPhone to work out your head angle, and never sent anywhere.
- Your sessions and history. They're stored on your iPhone only.
- Your settings, calibration and goal.
There's no account and no sign-in.
Sent to help improve the app
So we can see what's working, the app sends a few usage events, such as finishing a setup step, starting or ending a session (with its length, good-posture percentage and number of nudges) and a nudge playing. If the app crashes, a crash report is sent. These carry a random identifier made for this app on your iPhone, not your name, email or Apple Account, and they're never used for advertising or tracking.
