This deletes the account itself, not just the app. You do not need the game installed, and you do not need to ask us.
Signing in below disables the account immediately and signs out every device it is on. Thirty days later a scheduled job erases what identifies you:
The account row itself is kept in an anonymous state, because removing it would tear holes in the match history of every player you ever played against. After the erasure it holds nothing that identifies you.
The thirty days are a grace period, so that an account deleted in anger or by somebody who got hold of the phone can still be recovered. Write to contact@amcrafts.in from the account's e-mail address within that window to undo it — or to ask us to bring the erasure forward, which we will also do.
Everything in the account: coins, gems, every unlocked board theme and token, your level and experience, your rating and rank, season progress and tournament entries. None of it is refundable and none of it can be moved to another account. Progress stored on the phone itself is not touched by this; uninstalling the game removes that.
A guest account has no e-mail address and no password, so there is nothing to sign in with here and no way for us to tell which account is yours. Uninstalling the game abandons it and it is removed in the ordinary course.
E-mail contact@amcrafts.in from the address on the account and we will delete it within 30 days.
