What does this browser privacy checker test?

The tool audits 7 privacy categories: IP & Network (IPv4, IPv6, and WebRTC leaks), DNS Privacy (whether your DNS queries are exposed), Fingerprinting (canvas, fonts, screen, and other browser fingerprint vectors), Privacy Settings (cookies, local storage, referrer policy), Connection Security (HTTPS, HSTS), Tracking Protection (ad/tracker blocking status), and Browser Security (security headers, mixed content). Each category produces a score and actionable findings.

Is this privacy check tool free?

Yes, completely free with no signup required. All checks run entirely in your browser. No data is sent to any server — the tool is fully client-side by design.

Does this tool store my IP address or browser data?

No. Every check runs locally in your browser. Your IP address, DNS resolver, and fingerprint data are never uploaded or logged on any server. This tool was built with privacy as the core design principle.

What is an IP leak and why does it matter?

An IP leak occurs when your real IP address is exposed to websites even though you are using a VPN or proxy. The most common cause is WebRTC, a browser API that can bypass VPN tunnels and reveal your local and public IP. This allows websites to identify your location and ISP despite VPN use. This tool tests both your visible IP and any WebRTC leaks.

A DNS leak happens when your DNS queries — the lookups that translate domain names into IP addresses — are sent to your ISP's default DNS servers instead of through your VPN or a private resolver. This means your ISP can see every website you visit even if your traffic is encrypted. The DNS leak test checks which resolver your browser is using and whether queries are leaking outside your private tunnel.

What is browser fingerprinting?

Browser fingerprinting is a tracking technique that identifies you based on the unique combination of your browser's properties — such as your screen resolution, installed fonts, canvas rendering, WebGL capabilities, timezone, and language settings. Unlike cookies, fingerprinting works without storing anything on your device. The tool measures your fingerprint entropy to assess how uniquely identifiable your browser is.

How can I improve my privacy score?

Common improvements include: using a reputable VPN with a WebRTC kill switch, switching to a privacy-respecting DNS resolver (such as Cloudflare 1.1.1.1 or NextDNS), installing a browser extension like uBlock Origin for tracker blocking, enabling HTTPS-Only mode in your browser, disabling third-party cookies, and using a privacy-focused browser such as Firefox or Brave with hardened settings.

How is the privacy score calculated?

The overall score (0–100) is a weighted aggregate of 7 category scores: IP & Network, DNS Privacy, Fingerprinting, Privacy Settings, Connection Security, Tracking Protection, and Browser Security. Each category runs multiple individual checks; each passed check contributes points toward that category's score. The final score is colour-coded: Excellent (80–100), Good (60–79), Fair (40–59), or Poor (below 40).

What Does the Internet See When You Visit a Website?

Your browser reveals more than you think -- your real IP address, your location, your DNS provider, even a unique fingerprint that can track you across websites. This tool shows you exactly what's exposed.

All checks run in your browser. Only one lightweight API call reveals your public IP.

Who Is This For

VPN Users

Verify your VPN is actually hiding your real IP. WebRTC leaks can expose you even with a VPN active.

Security Professionals

Check your operational security before an investigation. Make sure your identity doesn't leak through your browser.

Privacy-Conscious Users

See how unique your browser fingerprint is and which tracking methods can identify you across the web.
