ShizuWall No Root/VPN Firewall

ShizuWall – No-Root, No-VPN Android Firewall
Take full control of your privacy!

ShizuWall is a lightweight, privacy-first firewall that lets you block internet access for any app without rooting your device or using a battery-draining VPN service. Powered by Shizuku (or built-in local ADB), it works seamlessly on Android 11 and above — giving you true system-level control with almost zero overhead.

Why Choose ShizuWall?

No root required — Works on stock, non-rooted devices
No VPN tunnel — No speed loss, no extra battery drain, no connection drops
Real per-app blocking — Uses Android's native connectivity framework (Chain-3 style) to completely cut off network access — no packet capturing or redirection
Privacy-first & fully local — Zero data leaves your device, no analytics, no tracking, no telemetry
Super lightweight — Clean Material You design, minimal resource usage, fast & responsive
Advanced modes (v4.2+)
Whitelist mode: Only allowed apps can connect
Foreground-only mode: Block background data while allowing foreground use

Automation ready — Easily integrate with Tasker, MacroDroid or ADB broadcasts for auto-rules on boot/Wi-Fi change

Perfect For:
Blocking ads, trackers & background data hogs (Facebook, TikTok, Google apps, etc.)
Saving mobile data & battery life by restricting unnecessary apps
Creating a focused / distraction-free mode (block social media & games)
Enhancing privacy & security without compromises
Parental control — isolate apps for kids
Stopping sneaky background uploads/downloads

Super Easy Setup (Takes ~1 Minute)

Install Shizuku from Play Store (or use our built-in local ADB mode)
