Privacy Check
Automated battery of browser privacy tests. Results are computed in your browser. Some tools contact Cloudflare endpoints or this server's own reflection endpoints. No data is stored or tracked.

Understanding Your Results
What is a WebRTC leak?
WebRTC (used for voice/video in browsers) can expose your real IP even when using a VPN. The browser negotiates ICE candidates directly, potentially bypassing your proxy. Disabling WebRTC in browser settings eliminates this risk.
What does DNS resolver mean?
Your DNS resolver translates domain names to IPs. If it's your ISP's resolver, they can log every domain you visit. Switching to encrypted DNS (DoH/DoT) with Cloudflare (1.1.1.1) or Quad9 (9.9.9.9) improves privacy.
Why does fingerprint matter?
Websites can identify you based on your browser's unique combination of screen resolution, fonts, plugins, canvas rendering, and more — even without cookies. Browsers like Brave or Firefox with resistFingerprinting help mitigate this.
Is my data stored?
Diagnostic results are never sent to our servers. Some tools contact Cloudflare endpoints directly from your browser. A session identifier is stored locally in your browser's localStorage to simulate realistic browsing behaviour — it never leaves your device. You can clear it anytime via your browser's storage tools.
