Boom Duel (Google Play package com.quarterpi.boomduel, and on the App Store) is developed by Quarter Pi. Playing offline needs no account. When you first play online, the game creates an account for you automatically; you can also link it to Sign in with Apple or Google Play Games.

Delete your Boom Duel account in the game

  1. Open Boom Duel and tap the gear icon to open Settings.
  2. Tap Delete account.
  3. Read the warning and confirm.

Your online account is deleted straight away and the game starts fresh on this phone.

Can’t open the game?

Email support@quarterpi.com with the subject “Delete my Boom Duel account”. Include your display name (shown on the game’s Online screen) and, if you signed in, whether you used Apple or Google Play Games. We’ll confirm and delete the account within 30 days.

What gets deleted

  • Your account, display name, rating, wins and losses
  • Your cloud save (stars, coins, unlocked items)
  • Notification tokens, and the link to your Apple ID or Play Games profile (we also revoke Sign in with Apple)
  • Your matches in progress, which end as a forfeit

Finished matches stay in your opponents’ history with your name replaced by “Deleted player”. We keep purchase records only as long as tax law requires. Progress saved on your phone stays until you uninstall the game. Purchases remain tied to your Google Play or Apple account, so “Restore purchases” in a reinstalled game gives back one-time items.
