It is possible to save your game data on the Cloud Server by accessing "Cloud Sync". When you perform "Cloud Sync", the date and time of the save data on the device and the Cloud Server is compared, and the latest data is synced.
*It is not possible to select an old data.

By logging into the account used to save data on the Cloud Server and accessing "Cloud Sync", one is able to continue playing from where they left off even after re-downloading the app.
*Please note that only the latest data on the Cloud Server will be used.

"Cloud Sync" can be accessed without the Apple ID or Google account used to purchase the app, and by logging into
the account used to save data on Cloud Server and performing "Cloud Sync", one is able to play the game with the same data on multiple devices.
*As only the save data is synced, you are still required to download the app separately in order to play the game on multiple devices. If you are on the same account that was used to purchase and download the app initially, you may re-download it free of charge from the Appstore or Google Play. Attempting to download the app from a different account will result in a charge being incurred.
