Snaps run out of a squashfs partition, but the app may save app config in the user's home directory (if they request the HOME interface, I believe).
After fighting with node, vlc and ffmpeg snaps not working reliably, I had to add a warning for my PhotoStructure users on Ubuntu to avoid those packages (and how to install them via apt).
I agree with a bunch of people here: snap promises some great features, but in practice the horrible performance, additional resource consumption, and spotty reliability led to me actively avoiding snap packages and looking for an alternative installation.
