What is it?

ShizuWall is an Android firewall for Android 11 and later that blocks networking per app without creating a VPN tunnel or intercepting packets. It works by calling Android's connectivity chain 3 through a privileged backend: Shizuku, LibADB (paired over Wireless Debugging, no computer required), or root.

Rules are applied per package, including work-profile and clone copies of an app. The app offers a Quick Settings tile, a widget and a floating button for fast toggling, and it can be controlled from adb, Tasker or MacroDroid through broadcasts that switch the firewall, block specific apps or activate saved profiles. Rules are cleared on reboot, and the project states it works offline with no analytics or telemetry.
