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 Open source — Full code on GitHub under GPLv3 — transparent and community-driven 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) Start Shizuku via wireless debugging (no PC needed) Open ShizuWall → Grant permission → Tap to block/allow any app! Quick tip: Rules reset on reboot due to Android security — enable Shizuku auto-start or use Tasker for one-tap restoration. Disclosure: This app uses the AccessibilityService API to detect the active foreground application. This is strictly required to dynamically un-firewall the app you are currently using and re-apply the firewall rules when the app is closed or put in the background. We do not use this API to collect, store, or share any personal data, screen content, or user behavior
