SFDNS

An advanced, lightweight, privacy-focused Android application for changing DNS servers and tunneling DNS queries securely via DNS-over-HTTPS (DoH). Built natively with Kotlin and Android VpnService to capture DNS traffic and forward it to chosen resolvers with zero battery drain.

🌟 Key Features 🛡️ Privacy First & Secure DoH: Supports encrypted DNS-over-HTTPS (DoH) queries to prevent DNS spoofing, eavesdropping, and ISP hijacking. ⚡ Lightweight Local VPN Routing: Captures only DNS traffic (port 53 UDP/TCP). Other internet traffic is not routed through the app. 🚀 Pre-configured Anti-Sanction & Fast Servers: Cloudflare (1.1.1.1) Google Public DNS (8.8.8.8) Quad9 (9.9.9.9) Shecan (178.22.122.100) Electro (78.157.42.100) Radar Game (10.201.201.201) 403 Online (10.202.10.202) Begzar (185.55.226.26) Custom Primary & Secondary DNS input support (IPv4 & IPv6) 🧩 Home Screen Widgets & Quick Tile: Toggle DNS connection from the Quick Settings tile or from interactive app widgets. 🎨 Modern Cyber Aesthetic UI: Smooth animations, dark mode, ping test indicators, and real-time DNS status feedback. 🔄 Auto-Connect on Boot: Optional background startup after device reboot. 🎮 Gaming Radar Benchmark: Real UDP/TCP socket-based ping measuring lowest latency for online games. 🛡️ Split Tunneling (App Bypass): Selectively bypass banking or domestic apps from DNS routing.
