Check if your IP, VPN & browser are leaking data
Our privacy check tool analyzes your current connection to determine how much information your browser and network are revealing to websites you visit. It examines your IP address for signs of VPN or proxy usage, checks for WebRTC leaks that can expose your real IP address even when using a VPN, and evaluates DNS leak potential. The tool also detects whether your IP is associated with known data centers, hosting providers, or anonymizing services.
Every time you visit a website, your browser sends a collection of data that can be used to identify and track you. This includes your IP address, browser type and version, operating system, screen resolution, installed plugins, language preferences, and more. When combined, these data points create a surprisingly unique fingerprint. Understanding what you expose is the first step toward protecting your online privacy.
To use this tool, simply load the page and it will automatically analyze your connection. The results will show your detected IP address, whether a VPN or proxy is detected, whether WebRTC is leaking your real IP, your approximate geolocation, and your ISP. If you are using privacy tools, this check helps verify they are working correctly.
Your browser reveals your IP address, User-Agent string (browser name, version, and operating system), preferred language, timezone, screen resolution, installed fonts and plugins, whether cookies and JavaScript are enabled, your referrer (the page you came from), and WebGL renderer information. Websites can combine these data points to create a fingerprint that identifies your browser across visits, even without cookies.
WebRTC (Web Real-Time Communication) is a browser technology used for voice calls, video chat, and peer-to-peer file sharing. By design, WebRTC needs to discover your real network interfaces to establish direct connections. This means it can expose your real local and public IP addresses to websites even if you are using a VPN. A WebRTC leak occurs when this happens unintentionally, defeating the purpose of your VPN.
Browser fingerprinting is a tracking technique that identifies users by collecting unique characteristics of their browser and device. Unlike cookies, fingerprints cannot be easily deleted because they are derived from your system configuration. A fingerprint might include your screen resolution, timezone, installed fonts, canvas rendering behavior, audio context properties, and WebGL capabilities. Research shows that most browser fingerprints are unique among millions of users.
Use a reputable VPN to mask your IP address, and verify it with this tool. Install a browser extension like uBlock Origin to block trackers and ads. Use Firefox with Enhanced Tracking Protection or Brave browser which blocks fingerprinting by default. Disable WebRTC in your browser settings or use an extension to prevent leaks. Consider using a privacy-focused DNS provider like Cloudflare (1.1.1.1) or Quad9 (9.9.9.9) to prevent DNS-based tracking.
Incognito mode only prevents your browser from saving your browsing history, cookies, and form data locally on your device. It does not hide your IP address from websites, prevent your ISP from seeing your traffic, or stop browser fingerprinting. Websites can still identify you by your IP address, and your employer or school network can still monitor your activity. For real privacy, you need additional tools like a VPN and anti-tracking extensions.
