Data sync is available for membership grades.

 

You can get the same grade if you will do the Data sync through Facebook, Google, Apple login.
If you've been playing for a long time, but you've reinstalled it without syncing, please contact us individually through the "Contact Us" button at the top right.

If you want to know how to sync the game progress, please refer to "I'd like to save the progress" on the Data Sync Page.
