Decide which apps get wifi and which get mobile data, one tap each. No root, no filtering, no logs — and no internet permission in the firewall itself.
Block-only, and it cannot phone home. It is a local VPN slot that drops packets for the apps you blocked. It holds no internet permission itself, so it cannot log, upload or fetch anything — check the permission list.
This is the whole list. Android prints the same thing under Settings › Apps › Permissions once the app is on your phone, and it was not written by us — check one against the other.
| See your installed apps | The list you are switching on and off is the app list — there is nothing to show without it |
|---|---|
| See the network | Whether you are on wifi or on data, so the right rule applies the moment it changes |
| Which SIM carries data | For the dual-SIM rules only — the number, the calls and the messages are never touched |
| Keep running / start after a reboot | A firewall that stops when you lock the phone is not a firewall |
| Internet | Absent. The permission does not exist in this app |
Android 11 and up. Bought once, yours to keep: no account to make, no subscription, and no upgrade screen inside the app — the licence you buy unlocks it and every version after it.
