Privacy Tools — Check What Your Browser Reveals About You

Every time you visit a website, your browser shares a surprising amount of information — not just your IP address, but your browser version, operating system, screen resolution, time zone, installed fonts, language settings, and even battery level on mobile. Some of this is necessary for sites to function correctly; some is used for fingerprinting and tracking. This tool shows you exactly what's visible.

What information does your browser share?

IP address: Your public IP, which reveals your approximate location and ISP. This is unavoidable without a VPN or proxy — every website you connect to sees your IP.

User agent string: A text string identifying your browser (Chrome, Firefox, Safari, Edge) and its version, along with your operating system and version. Sites use this to serve appropriate layouts and to track browser usage statistics.

Screen resolution and color depth: Your monitor's resolution and how many colors it can display. Part of the fingerprinting data set.

Time zone: Your system time zone, inferred from how your clock is set. Reveals roughly where in the world you are even if your IP is masked by a VPN in the wrong region.

Language and locale: Your browser's language preference (e.g., en-IN for Indian English) and system locale.

Installed plugins: Older browsers leaked this more extensively; modern browsers have largely locked it down, but some information may still be accessible.

Canvas fingerprinting: Websites can render hidden graphics using the Canvas API and measure the exact pixel-level output, which varies slightly between different hardware and software combinations. This creates a near-unique fingerprint even without cookies.

WebGL information: Details about your GPU and graphics driver, another fingerprinting vector.

Common use cases

Privacy awareness: Most people are surprised by how much their browser reveals without any cookies or explicit tracking. Seeing the actual data your browser shares is the first step toward understanding online tracking.

VPN verification: Check whether your VPN is masking your IP and time zone correctly. If the IP shows your home ISP, the VPN isn't working. If the time zone still shows your real location while the IP shows a different country, sites can potentially deduce your real location.

Browser fingerprint assessment: See how unique your browser's combination of settings is. A unique fingerprint means you can be tracked across sites even without cookies.

Testing privacy browser settings: After changing browser settings or enabling tracking protection, reload this page to see what changed in the reported data.

How to improve your privacy

No single measure makes you completely anonymous, but layering several approaches reduces your tracking surface: use a VPN for IP masking, use Firefox with strict tracking protection or a Chromium-based browser with uBlock Origin, avoid browser extensions that request unnecessary permissions, use private/incognito mode for sensitive browsing (though this doesn't hide your IP), and keep your browser updated so fingerprinting-resistant changes are applied.

For the highest privacy, Tor Browser is designed specifically to make all users' fingerprints look identical — the same browser version, the same window size, the same JavaScript API responses — making individual fingerprinting nearly impossible.

Limitations

This tool shows you a snapshot of what's visible at the time you load it. The full range of tracking techniques used by large ad networks is more sophisticated than what a simple browser info display can show — including cross-device tracking, probabilistic matching, and first-party data correlation. This tool helps with awareness, not comprehensive anti-tracking analysis.
