WebRTC Leak Blocker

About

Stop WebRTC IP leaks and take back control of your online privacy.

WHY YOU NEED THIS
WebRTC is built into every modern browser. While useful for video calls,
it can expose your real IP address to any website — bypassing your VPN
entirely. This is known as a WebRTC IP leak.

WHAT IT DOES
• Blocks WebRTC IP leaks in real time
• Prevents local network IP exposure (192.168.x.x ranges)
• Forces WebRTC through your proxy or VPN tunnel
• Live IP detection — see exactly what websites can detect
• Works with all VPNs (NordVPN, ExpressVPN, Surfshark, etc.)
• Zero configuration — instant protection on install

THREE PRIVACY TIERS
Maximum — Forces all WebRTC through proxy. Blocks non-proxied UDP.
Best for VPN users who want zero leaks.
Moderate — Hides your local network IP. Topology stays private.
Standard — Default Chrome behavior (for compatibility testing only).

HOW IT WORKS
Uses Chrome's official Privacy API (chrome.privacy.network.
webRTCIPHandlingPolicy) to enforce policy at the browser engine level —
it cannot be bypassed by websites.

WHO IS IT FOR?
• VPN users worried about WebRTC leaks
• Anyone who failed a test on ipleak.net or browserleaks.com
• Remote workers using corporate proxies
• Privacy-conscious users who don't want real IP tracking
