They can’t access all the files on your computer - if they want to access a file, they have to pop open an Open dialog and you have to choose that specific file. As on Apple’s iOS, apps listed in the Mac App Store must run in a restricted sandbox environment.

The main reason many apps aren’t available on the Mac App Store is the “ sandboxing” requirement.
