Yes, save files are compatible between all OS's, so you can move from Android to PC, Mac to Linux, Linux to Android... any combination you like :)
Here's the locations of all the save folders on each OS. Just take the contents from one location and copy-paste them into the other:
WHERE ARE SAVES LOCATED ON PC?
PC > Local Disk (usually C:) > Users > USERNAME > AppData > Roaming > RenPy > CorruptedKingdoms-1547378918
WHERE ARE SAVES LOCATED ON MAC?
~/Library/RenPy/CorruptedKingdoms
WHERE ARE SAVES LOCATED ON LINUX?
~/. renpy/CorruptedKingdoms/
WHERE ARE SAVES LOCATED ON ANDROID?
Android/data/com.domain.corruptedkingdoms/saves
NOTE: If you're running Android 11+ then Google has hidden your data folder. To access it you need to connect your phone to your PC with a USB cable or use an app like Solid Explorer or X-Plore to give you access to the folder again.
