You can delete your game account by going to the game settings (the gear icon on the top right of the game screen), selecting "Account settings," and after that, "Delete account."
Please note that deleting your account through the game settings is irreversible. Once the account is deleted, it can no longer be recovered.
If you want to delete all your data, please contact us via the in-game support. If you need assistance finding this option, check our guide on how to contact support through the in-game settings. Please note that we can't grant your data deletion request if your account has been banned.
