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

The name **De1984** is inspired by George Orwell’s novel Nineteen Eighty-Four, reflecting the app’s philosophy of resisting surveillance and reclaiming digital privacy. It symbolizes a reversal of the dystopian control described in the book, empowering users to take back control over their devices and data.
