Browser Security & Privacy Blog

Millions of people open incognito believing they're invisible. They're wrong. Your canvas, WebGL, fonts and GPU are fully exposed — here's the truth about private browsing.

Your GPU creates a unique ID on every site you visit — no cookies, no login required. How canvas fingerprinting works and how to block it in Brave, Firefox and Chrome.

How canvas, WebGL, audio, and font fingerprinting works — and how to test and reduce your uniqueness score. Covers all 32 signals UNDETECT.CLUB detects.

Step-by-step fix for every browser. WebRTC leaks expose your real IP address even when you're using a VPN — here's how to stop it in 2 minutes.

UNDETECT.CLUB vs BrowserLeaks vs Pixelscan vs EFF Cover Your Tracks — full feature comparison across 18 detection categories. Which tool should you use?

Cookies can be deleted. Fingerprints can't. A side-by-side comparison of how each tracking method works, why fingerprinting is harder to block, and what GDPR actually covers.

A VPN hides your IP. It does nothing for canvas, WebGL, audio, fonts, or timezone — the signals sites actually use to identify you. What VPN covers vs what fingerprinting bypasses.

Six actionable steps to lower your uniqueness score — from switching to Brave to blocking WebRTC to managing fonts. Each step rated easy/medium/hard with measured impact.

Canvas, WebGL, AudioContext, localStorage, ETag, HSTS supercookies, CNAME cloaking, WebRTC — 10 cookieless tracking methods with danger ratings and how each one works.

Your browser creates a unique audio signature using OfflineAudioContext — no microphone needed, no sound plays. How it works, who uses it, and how Brave and Firefox fight back.

Tor standardizes canvas, WebGL, fonts and timezone — making all users look identical. But behavioral fingerprinting, JS timing attacks, and exit node surveillance still apply. Full analysis.

navigator.webdriver, SwiftShader GPU, empty plugins, missing chrome.runtime — the signals that expose headless browsers, Puppeteer, Playwright, and Selenium. With detection code.

WebRTC IP leak, unique canvas hash, GPU via WebGL, timezone mismatch, font enumeration, UA spoofing inconsistency, audio fingerprint — 7 concrete signs with how to check and fix each.
