Gravity Icon is an offline Android physics playground and live wallpaper by NightLight Developers.
Data stays on your device
The app has no internet permission, accounts, advertising, analytics or tracking. It does not upload information to us or operate a collection server.
App icons, photos and motion
The app reads the launchable app icons you select for the playground. Your selection and settings stay in private device storage. If you choose a photo through Android's system picker, the app reads only the selected image and keeps a small private copy for the toy icon. It does not request access to your photo library. Restoring an app icon deletes its replacement photo copy.
Tilt and shake input from the device's sensors drives the on-device simulation. It is not sent anywhere. Live wallpaper is applied through Android's own controls, and your launcher decides which touches reach it.
Deletion and backups
Clearing app storage or uninstalling removes app-private selections, settings and photo copies. The Android app disables app-managed backup. Original photos and installed applications are not changed by choosing a toy image.
Third-party software
JBox2D runs locally as the physics engine. App icons remain the property of their owners.
