Wallz is operated by HistorySim LLC. Wallz helps you block selected distracting apps and complete timed wall sessions.
The app stores onboarding completion, wall-session preferences, selected Screen Time app/category/domain tokens, and subscription status on your device.
Wallz uses the camera and ARKit/LiDAR sensor data to detect whether the phone is pointed at a flat wall. Wallz uses motion data to detect when the phone is picked up during wall time. Camera, LiDAR, and motion data are processed on device and are not uploaded by Wallz.
If you grant Screen Time permission, Wallz uses Apple Family Controls and Managed Settings to shield selected apps, categories, and web domains. Screen Time tokens are handled locally by iOS and are not sold by HistorySim LLC.
Subscriptions are processed by Apple and managed through RevenueCat. RevenueCat may receive purchase identifiers and subscription status needed to unlock paid access.
Wallz does not track you across apps or websites and does not sell personal data.
