Real-Time Browser Privacy Score Inspector
Executes live WebRTC STUN checks, GPC headers, ad-blocker detection, and fingerprint entropy tests natively.
Before you start: what this scan sends
Four of the six checks read values your browser already exposes to every page — privacy signal, cookie setting, referrer, and device fingerprint attributes. Those touch the network not at all.
The other two make outbound requests to Google: a HEAD probe to pagead2.googlesyndication.com to detect a content blocker, and a STUN request to stun.l.google.com:19302 for the WebRTC leak test — which lets that server observe your public IP address. That is unavoidable: a browser-based WebRTC test has to expose your address to a STUN server in order to report whether it is exposed. Nothing is sent to us or stored anywhere.
Prefer not to? Nothing has run yet, and closing this page sends nothing. You can inspect your WebRTC settings directly in your browser instead — the Improving your result section below explains how.
Key Privacy Checks Explained
This audit reviews essential browser configurations that impact your daily online privacy.
WebRTC IP Exposure
Checks whether real-time communication protocols expose your public IP address. A secure result means your network identity is shielded from unauthorized discovery.
Global Privacy Control (GPC)
Verifies whether your browser transmits an official opt-out signal telling websites not to sell or share your personal browsing data.
Tracker & Ad Blocking
Detects whether known advertising and cross-site tracking scripts are blocked before they can monitor your web activity.
Browser Fingerprinting Exposure
Evaluates how unique your hardware, screen, and browser attributes appear to third-party tracking scripts across the web.
How to Improve Your Browser Privacy
Enable Global Privacy Control
Turn on “Do Not Track” or “Global Privacy Control” in your browser settings to automatically request privacy on supported websites.
Use a Trusted Content Blocker
Install a reputable open-source ad and tracker blocker to stop invasive scripts from loading across web pages.
Review Browser Permissions
Regularly audit installed browser extensions and site permissions (location, camera, microphone) to reduce unnecessary data access.
Frequently Asked Questions
Does this scan save or transmit my IP address?
No. Scan results are calculated live inside your browser session and are never saved, recorded, or logged on our servers.
Does private browsing mode protect against all tracking?
Private browsing prevents cookies and browsing history from saving locally on your device, but websites can still see your IP address and connection details.
How does tab locking help my privacy?
Browser privacy tools protect you from remote online trackers, while Locksy protects your active logged-in sessions from anyone nearby who has access to your physical computer.
Protect Open Tabs with Locksy
Locksy locks and encrypts your active browser tabs with master password protection and biometric unlock.
