Private by default
No ads and no cross-app tracking. Signed out, your Journal and collections stay on this device. Signed in, workouts, history, Journal entries, goals, collections and their drills sync to your private account and are deleted with it. Photo, video and voice recap files stay on your device unless you choose to stream a demonstration video to your TV. Health data stays on your device; a Journal recap of an imported workout syncs its activity, source and timing. Analytics and crash reports help improve the app, and you can turn them off in Settings. Read the privacy policy.
