You can permanently delete your Froggrid account and associated data from within the Froggrid Android app.
Open Froggrid → sign in → tap your name in the top-right corner of the main menu → check “Yes, I want to delete my account” → DELETE ACCOUNT → Yes.
Deleting your account permanently removes your Froggrid player account, login credentials, Play Games association, game results, leaderboard entries, and other data associated with that account.
Froggrid does not retain a backup copy of the deleted account data.
If you cannot access the app, contact privacy@lowexpectations.dev to request deletion.
