You can disconnect from Facebook or Apple ID in the game settings menu. Tap the cogwheel icon on the game’s home screen, then tap the disconnect button.

We strongly recommend keeping the game connected to your Facebook or Apple ID account to back up the progress to our cloud. When you disconnect the game from Facebook or Apple ID, your progress can no longer be restored. If you reinstall the game, the progress cannot be transferred to other devices, and any purchases tied to the account can no longer be restored.
