What is it?

De1984 is an Android app for controlling which installed apps can use the network. It lets you block apps separately on WiFi, mobile data and roaming, block LAN access, and set a global policy of either allowlisting or blocklisting by default. Several firewall backends are available: iptables for rooted devices, ConnectivityManager and NetworkPolicyManager through Shizuku, and a VPN-based backend that needs no root.

The app also covers package management. With Shizuku or root, you can enable or disable system apps, force stop running apps, and uninstall system or user apps, with filters for system/user apps and enabled/disabled state. Screen-off blocking and automatic rule application on network changes are included.

The project states that it has no tracking, analytics or telemetry, stores data locally, and contains no proprietary libraries. It is MIT licensed and buildable from source. Users of VPN mode must disable Android's "Block connections without VPN" setting, or allowed apps will be blocked.
