About This Site

The purpose

Browser fingerprinting is widely used and poorly understood. Most people know cookies can track them; far fewer know that a page can silently read their graphics hardware, measure their installed fonts, and hash their browser's pixel output — no consent dialog, no visible sign. The Browser Fingerprint Analyzer exists to close that gap by demonstration: run the same techniques trackers use, on your own browser, with every step explained.

Principles

• Local only. A tool that teaches about fingerprinting must not itself collect fingerprints. Everything runs in your browser; results are never uploaded and never stored. The privacy audit documents this line by line.
• Plain language. Every result comes with a readable summary, a specific data source, and a practical action — not just a hex string.
• No invented numbers. This site does not display uniqueness percentages, population estimates, or scores it cannot substantiate. Ratings are qualitative (Higher, Moderate, Lower, Unavailable) and always come with the reasoning.
• No exaggeration in either direction. Fingerprinting is neither harmless nor omnipotent. The guides describe real capabilities, real defenses, and real limits of both.

What the site includes

The analyzer runs five tests — Canvas, WebGL, Audio, Screen, and Fonts — with a before-and-after comparison mode for verifying whether privacy measures actually change your signals. The guide section explains each technique, and the reduction guide covers realistic defenses.

What the site deliberately is not

This is not a fingerprint database, not an anonymity checker, not a security product, and not a service with accounts or subscriptions. It cannot tell you that you are "safe" or "anonymous," because no honest tool can. It shows you observable facts about your browser and explains what they mean.
