Android AccessibilityService usage disclaimer (optional): O3’s optional Focus Protection uses the AccessibilityService API during user-started study sessions to detect which app is visible. If you open a distracting app, O3 returns you to your device’s Home screen and shows a focus warning. App identifiers are processed on-device; O3 does not read, store, or share screen content. You can disable access anytime in Android Settings.
The world is your oyster. You’ve got this!
