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!).
- Network Monitoring Screen: Real-time traffic tracking via local VPN. See which apps are actively trying to access the network and block or allow connections directly from the live monitoring log.
- 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: Advanced filtering based on user apps, system apps, network permission, disabled status, uninstalled leftover rules, or blocked-placement priority.
- Efficient: The app doesn't need to be constantly running in the background when utilizing Shizuku mode.
- Elegant Reapplying: Hassle-free user experience on startup.
