DoodleBolt has no sign-up. To run the leaderboard it creates an anonymous account automatically and stores a display name, your scores and a country code. Game progress and drawings never leave your device.
Open DoodleBolt → Settings (⚙️ on the home screen) → Leaderboard → Delete my leaderboard data. This deletes your leaderboard entry and the anonymous account immediately.
If you no longer have the app, email [email protected] with the display name shown on the leaderboard. We delete the entry and the account behind it within 30 days and confirm by reply.
Anonymous usage counts cannot be linked to you, so there is nothing per person to delete. Local progress is removed by uninstalling the app.
