A separate purchase of MobileSheets is required per platform. So if you purchased through Google Play, that can be used to install on your Android tablets, but if you are wanting to use a Windows device, that would require a purchase through the Microsoft Store. If you log into your Google account, you can check your list of purchases for the account. The same is true of the Microsoft Store. Just tap your profile icon in the store app, click Manage account/devices, scroll down and expand Order history, then you can view all of your purchases.

If you install on multiple devices, you will need to transfer your library which can be done with a library backup file or the sync library feature. To transfer your library using a backup file, open MobileSheets on your old tablet, tap the three dots at the top right of the library screen and then tap Settings->Backup and Restore->Backup Library. This will generate a .msb file in the folder you select which can be on the device or in the cloud. If you selected a local folder, transfer the file from that folder to the other tablet. Open MobileSheets on the new tablet, then go to Settings->Backup and Restore->Restore Library from Backup. After the restore completes, you will have access to your entire library on that device.
