A simple, open-source Android firewall that blocks app internet access using either Shizuku or a local VPN, with no root requirement.
- Dual Mode: Choose between the efficient Shizuku mode (recommended) or the no-setup-required VPN mode (or even use them at the same time!).
- Per-App Rules: Control Wi-Fi and Mobile Data access for each app individually.
- Import/Export: Save and load your firewall rules as a simple .json file.
- Sorting: Sort based on user and system apps.
- Efficient: The app doesn't need to be constantly running in the background.
- Elegant Reapplying: Hassle-free user experience on startup.
- App search and more
- Enable the Firewall: Press the "Enable" button on the main screen.
- Choose Mode: Toggle between "Shizuku" (requires setup) or "VPN" (works instantly).
- Block Apps: Tap the Wi-Fi or Data icons next to any app to block its access.
- Note: After rebooting your phone, for Shizuku mode, you must first start Shizuku, then re-open the app to re-apply the rules.
