What Do Trackers See?
Your browser is broadcasting personal data right now. Here's exactly what advertisers, trackers, and websites can see about you — without your permission.

The data above is visible to every website you visit. A VPN and privacy-focused browser can significantly reduce your exposure.
Understanding Browser Fingerprinting
Browser fingerprinting is a highly accurate method of identifying unique users and tracking their online activity without relying on traditional cookies. As you can see from the live audit above, your browser broadcasts a tremendous amount of sensitive information to every website you visit.
How Tracker Fingerprinting Works
Instead of placing a small file (a 'cookie') on your computer, modern trackers run hidden JavaScript to interrogate your browser about its exact environment. This involves reading your IP address, inspecting the active User-Agent string to determine your operating system, and running silent tests using your computer's hardware. By combining your screen resolution, installed fonts, time zone, and language settings, data brokers can create a unique "fingerprint" that identifies you across completely unrelated websites.
The Canvas and WebGL Threat
The most evasive trackers use Canvas and WebGL fingerprinting. These scripts force your browser to draw invisible text and 3D shapes. Because every combination of graphics card, drivers, and operating system renders pixels slightly differently, the resulting image serves as a permanent, unique identifier. Even if you clear your browsing data or use "Incognito" mode, your hardware rendering signature remains identical.
Why is this data collected?
This massive data harvesting fuels the targeted advertising industry. Ad networks build sprawling behavioral profiles of your habits, interests, and financial status based on the sites you visit. In some instances, it is even used for price discrimination—charging you more for flights or hotels based on your device or assumed demographic. Using a comprehensive VPN and a hardened browser with strict tracking protection is the only consistent way to obscure this data.
