If you have cookies enabled it should save the progress from recent auto saves but depending if you like to remove cookies alot or if you have software that deletes it for you you might get raped by bad luck if anything you can create a folder to hold your exported saves for easy storage by right clicking> create new> folder then name it how ever you like even override saves by naming the new save over it (think there is something similar on mobile too but idk)
if you’re gonna do this i will give advice save frequently I can say from a guy that had to export from coc(corruption of champions) you’ll thank yourself for saving so frequently
