Where is my progress saved, and how do I move it to a new device?
Progress is saved on your device only. There is no account and no game server, so the game plays fully offline. To move it, open Settings, Progress, Make a backup code on the old device and keep the code safe. On the new device open Settings, Load a backup code, paste it and confirm. Loading a code replaces the progress on that device, and anyone who has the code can load your progress, so keep it to yourself.
