FireWall Blocks1.5.shynoid

Block individual apps’ Wi-Fi or mobile-data access with FireWall Blocks, giving you per-app control over which programs can reach the internet. The firewall works through either Shizuku or a local VPN, and it does not require root access. Its dual-mode design lets you select the efficient Shizuku mode, use the VPN mode without setup, or run both modes together.

The main screen provides an Enable button, while app rows expose separate Wi-Fi and Data controls for creating access rules. A real-time Network Monitoring screen, opened from the top-right menu, shows apps attempting network connections through the local VPN and lets you allow or block requests from the live log. Rules can be saved to or restored from a simple .json file. Search and sorting tools filter entries by user apps, system apps, network permission, disabled state, leftover rules for uninstalled apps, or priority given to blocked items.

Shizuku mode avoids keeping FireWall Blocks running continuously in the background and reapplies selected rules on startup. After a phone reboot, Shizuku mode requires starting Shizuku and reopening FireWall Blocks so the rules can be applied again. It suits people who want to restrict data use, isolate selected apps, or inspect connection attempts without using a root-based firewall.

Version 1.5.shynoid is open-source software for Android 11 and later in the Internet & Browsers category, with Universal architecture support.
