A guest account is an account within a game that is not linked to an external service like Facebook or LINE. With a guest account, all game progress and data are stored locally on your device. However, it's crucial to be aware that this data is not backed up on external servers.

This means that if you ever reinstall your phone's operating system or manually delete game-related files from your device, all the game data associated with the guest account will be permanently erased, and there won't be a way to recover it. Therefore, it's recommended to consider linking your game account to WolffunID to safeguard your progress.
