You can freely create files in $SNAP_USER_DATA - the per-user data directory or $SNAP_DATA - the global data directory (for daemons).
If you want to write to other locations you need an interface to do it. For example you can use the home interface to get write access to most of the $HOME directory.
You can do this by just defining a „home” plug on your application.
