De1984

De1984 is a free, open-source Android privacy utility combining application firewall controls with package management. It allows users to restrict network access for individual applications through root, Shizuku, or VPN-based methods. The application automatically selects an appropriate firewall backend according to device capabilities. Supported configurations can control Wi-Fi, mobile data, roaming, and local network access. Global allowlist and blocklist policies simplify managing network permissions across installed applications. Screen-off restrictions help reduce background data consumption. Its package manager can enable, disable, uninstall, or force-stop applications using Shizuku or root privileges. De1984 stores data locally and operates without telemetry, analytics, or proprietary tracking libraries.
