Flatpak Permissions and Sandboxing
One of the main goals of Flatpack is to increase the security of desktop systems by isolating applications from each other. This is achieved using sandboxing and means that, by default, applications running Flatpack have very limited access to the host environment. this includes:
- No access to any host files except runtime, app, ~/.var/app/$FLATPAK_ID, and $XDG_RUNTIME_DIR/app/$FLATPAK_ID. Only the latter two are writable
- There is no access to the network
- No access to any device nodes (other than /dev/null, etc.).
- There is no access to processes outside the sandbox.

Flatpak’s strength lies in its up-to-date approach to software software delivery. It removes traditional constraints and provides a simple answer for computer programs, regardless of the programming language they use, the hardware they use, or the frameworks they use.
