De1984

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.
