ZephyrNG: Secure DNS & Proxy

ZephyrNG is a lightweight, privacy-focused network utility designed to give you complete control over your device's traffic and DNS queries. Built with a high-performance native engine, ZephyrNG provides robust encryption, custom proxy routing, and an on-device application firewall without compromising your connection speed or battery life.

🛡️ Key Features:

• Encrypted Next-Gen DNS
Support for modern secure DNS protocols including DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), DNS-over-QUIC (DoQ), and DNS-over-HTTP/3. Connect to top security providers (Cloudflare, Quad9, Google, AdGuard DNS) or specify your own custom upstream resolver.

• High-Performance Proxy & VPN Client
Easily import, manage, and connect to secure network profiles. Supports industry-standard protocols including WireGuard, Shadowsocks, V2Ray/Xray, and modern UDP tunnels for seamless, encrypted data transmission.

• Per-App Firewall Management
Take control of which apps can access the internet. Block network access for specific apps on Wi-Fi or Mobile data to save bandwidth, prevent background tracking, and protect personal privacy.

• User-Defined Domain Rules & Custom Lists
Create custom whitelist and blacklist rules. Import your own custom domain lists via URL to inspect and route network traffic according to your preferences.

• Detailed Network Insights
Inspect real-time network request logs, analyze DNS resolution latencies, and monitor bandwidth usage directly on your device.

🔒 Privacy First:
ZephyrNG operates 100% on your local device using Android's standard VPNService API to route traffic securely into a local loopback. No logs are collected, and no traffic data is transmitted to external servers.

Permissions Notice:
• VPNService: Required to establish a local tunnel for encrypting DNS queries and routing proxy traffic.
• QUERY_ALL_PACKAGES: Required for the Firewall feature to allow users to select which individual installed applications are permitted or restricted from network access.
