can i sync savedata from android to pc? is it saved in a file somewhere?
You can't sync them, however you can import them to another platform.
Click on the book on the menu and go to the Stat tab. From there you should be on the unlock tab and you can see a button "Copy achievments". It will give you a text that you just have to use in the "Load achivement" button on the device you want.
It will not take your current progress in a dungeon but at least you have all the games modes, heroes, items and monsters that you have unlocked so far
