De1984

Privacy-focused Firewall and Package Manager for Android devices
New in version 2.4.9
- Improved permission validation and system health checks
- Enhanced reliability of the VPN backend management
- Added optional verbose logging (can be enabled in Settings)
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.
