Delete your Windbound Letters data
This removes the player record stored for this game. It does not delete your Google account.
In the game, you can delete the player record for the account you are using. The game sends that request with your session. We then delete that record for Windbound Letters: the session, the Play Games link for this game, the nickname, a stored Play Games player name, and stored leaderboard results.
If you cannot open the game, email support@lowinhand.com. Include Windbound Letters, your Google Play Games player name if you linked one, and the anonymous nickname shown for you in the game. We may need to confirm that the request is yours before deleting anything.
Saved Games files are kept by Google. To delete that file outside this game, delete your Google Play Games profile data as described by Google.
