Privacy-focused Firewall and Package Manager for Android devices
De1984 is a powerful Firewall and Package Manager for Android devices with multiple backend support for maximum flexibility and performance.

How to install
Download the APK from the button at the top of this page.
Allow “Install unknown apps” for your browser or file manager only, not for every app.
Open the downloaded file and confirm the installation.
If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
