## What it is
ShizuWall is a lightweight Android firewall app that controls per-app network access without using a VPN tunnel. It works on Android 11+ by leveraging Shizuku, a local ADB daemon, or root to toggle Android's connectivity controls, with a privacy-first, offline-only design.

## Use cases
- block an app from using mobile data or wifi without a vpn
- firewall apps on android without vpn tunnel
- control per-app network access using shizuku
- offline firewall app with no telemetry
- automate app network blocking with adb broadcast commands
- toggle firewall quickly from quick settings or a widget

## When to choose
- you want per-app network blocking on Android 11+ without the battery and routing overhead of a VPN-based firewall
- you already use Shizuku, root, or wireless debugging and want a privacy-first, offline firewall
- you need automation hooks (adb broadcasts, widgets, quick settings) to toggle app networking

## When to avoid
- your device is below Android 11 or you cannot grant Shizuku/ADB/root privileges
- you need fine-grained rules like per-domain or per-IP filtering, which VPN firewalls provide
- you want packet-level inspection or traffic logging
