Delete your Brassline Salvage account
This removes your account, signs out every device, removes your leaderboard entries and deletes your email address and display name. Your offline campaign save on your phone is not affected. You can also delete the account inside the game under Account.
A record that a Google Play purchase token was used stays attached to the deleted account so it cannot be claimed by another account and so refunds can be reconciled. For a purchase made on a deleted account, write to hello@thecoffeelayer.com with the Google Play order number.
