Android firewall without root or VPN.
Privacy-first, local-only, powered by Shizuku / local ADB daemon.
- No root / no VPN: avoids packet interception and persistent VPN tunnel side effects.
- Per-app network control: toggles app networking through Android's
connectivitychain-3 controls. - Privacy-first by design: offline-first, no analytics, no telemetry, no tracking.
- Automation ready: supports
adb broadcastcommands for scripts and task automation.
- Android 11 (API 30) or higher
- One control backend:
- Shizuku or
- built in local ADB daemon (LibADB flow)
These are the platform commands used through Shizuku or the local daemon:
