Someone already answered so I'll just give the same information but with a bit more detail. Due to the fact that I have a copypasta from the discord.
WHERE ARE SAVES LOCATED ON ANDROID? Android/data/com.domain.corruptedkingdoms/files/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.
