What is an IP leak test?
An IP leak test checks if your real IP address is exposed when using VPN or proxy services. This tool tests WebRTC leaks and analyzes browser fingerprinting to identify potential privacy vulnerabilities.
Your Network Privacy, Exposed
Sentry checks your browser for WebRTC leaks, reveals your browser fingerprint, and audits your connection security — all without sending data to any server.

Frequently Asked Questions
What is WebRTC leaking?
WebRTC leaking occurs when browser WebRTC functionality bypasses VPN tunnels and reveals your real IP address. This test checks for local IP addresses, server reflexive addresses, and potential relay leaks.
Is my data stored or sent to servers?
No, all processing happens in your browser. We use free external APIs for IP geolocation only, but no personal data is stored on our servers. Scan history is saved locally in your browser using localStorage.
What is browser fingerprinting?
Browser fingerprinting identifies your device based on unique characteristics like screen resolution, installed fonts, WebGL renderer, audio fingerprint, hardware specs, and other browser features. This tool shows what information your browser reveals to websites.
How accurate is the privacy score?
The privacy score analyzes cookies, Do Not Track, ad blockers, HTTPS usage, secure context, third-party cookies, and timezone consistency. It starts at 100 and deducts for each privacy-negative signal. A score above 90 indicates strong privacy protection.
What information does the report include?
The export report includes your IP addresses, network provider details, geolocation, device and browser information, hardware specs, browser fingerprint hashes, connection details, security status, and privacy analysis. It is downloaded as a plain text file.
