Delete accounts
To give your players more control over their personal data, you can provide a way to delete their own account by using the DeleteAccountAsync() API. This permanently deletes the player’s account. You should inform and prompt the player before calling this API.
Offering this option is a requirement for iOS applications as part of the App Store Review Guideline 5.1.1.
Note: DeleteAccountAsync() only deletes the player’s Unity Authentication account. Upon such a deletion request, you must delete all associated player data connected to the player’s Unity Authentication account and other UGS services you use.
