A personal fork of M66B/NetGuard — a no-root Android firewall — with extra features for fine-grained network control.
Block or allow any app's access to mobile data and Wi-Fi independently, with no root required.
Lets you temporarily allow a blocked app through the firewall for a fixed duration without permanently changing its rules.
- A timer icon appears next to any app that is blocked on mobile
- Tap it to pick a duration: 10 min, 30 min, 1 h, 12 h, or 24 h
- While active the icon shows remaining time and turns green
- When the timer expires the app goes back to blocked automatically
- Applies to mobile/other connections only (not Wi-Fi)
Displays a detailed log of outgoing IP traffic per app — see exactly what your device is connecting to in real time. Can be exported.
Block specific addresses per app while leaving the rest of its internet access intact. Useful for stopping apps from phoning home without fully blocking them.
Get a notification whenever a new app is installed, with a direct option to allow or block it immediately.
Download the APK from the Releases page, enable "Install from unknown sources" on your phone, and install.
