A lightweight, privacy focused Android firewall application that blocks network connections for selected apps without requiring root access or VPN. ShizuWall leverages Shizuku and libADB to provide powerful network control capabilities. Requires Android 11 (API 30) or higher.
Premium
- No Root or VPN Required: Most Android firewalls require either Root access or a VPN service. ShizuWall uses Shizuku or a local ADB daemon, providing native system-level control without the common VPN drawbacks.
- Per-app System Networking Control: Uses Android's
connectivityservice (chain-3) to enable/disable networking on a per-app basis — no packet interception, no VPN tunnel. - Privacy-first Design: The app is offline-first and does not phone home. There is no analytics, no tracking and no telemetry.
-
Firewall rules are applied using platform commands and are automatically cleared on device reboot (Android security limitation).That means, rebooting will revert anything done by ShizuWall.
-
No network calls from the app itself — it does not send any data to external services. The application requests
android.permission.INTERNETpermission to only support wireless debugging pairing (LibADB) features (connecting to the local ADB daemon). ShizuWall is designed to operate locally and does not initiate any connections to external servers.
