Help, frequently asked questions, and contact information.
Frequently asked questions
My best score or settings disappeared.
ONE BUMPER stores gameplay settings and progress locally on the device. Deleting the app or clearing its local data can remove that information.
Why am I seeing an advertising or tracking permission?
ONE BUMPER uses Google AdMob for advertising. On iOS, the system may ask for App Tracking Transparency permission. You can allow or deny the request; the game remains playable either way.
Why is an ad not appearing?
Ad availability can vary by region, network conditions, consent status, and advertising inventory. The game is designed to continue even when an ad is unavailable.
Sound or haptics are not working.
Check the in-game settings, device volume, silent mode, and iOS haptic settings. Restarting the app can also resolve temporary audio issues.
How do I report a bug?
Email the support address with your device model, iOS version, what happened, and the steps that caused the issue. A screenshot or screen recording is helpful when available.
