Delete my data
Brick Quad Rush has no accounts, so there is no account to delete. Your data lives in two places:
On your phone
Uninstall the game. This removes your stars, unlocked stages and settings from the device immediately.
Analytics and crash reports
Email brickquadrush-support@v15hnu.dev with the subject "Delete my data". We'll reply with how to find the app-instance ID on your phone and delete the associated analytics data within 30 days. Otherwise Google deletes it automatically after its retention period.
