Web browsers expose dozens of signals by design. Most users have no idea. Here's a quick primer on what gets leaked — and why it matters.
The moment your browser connects, it sends HTTP headers revealing your operating system, browser version, language, and any previously set cookies — before you've clicked anything.
Embedded scripts query your screen resolution, GPU, CPU core count, battery level, installed fonts, and dozens of other hardware signals to build a unique fingerprint of your device.
A WebRTC design flaw exposes your real local IP address to every website you visit, bypassing VPN protection entirely. Most VPN users are unaware this is happening.
Ad networks log every mouse movement, scroll depth, idle time, and click — building a behavioural profile that can identify you across sessions without any cookie or account.
Privacy-focused browsers, content blockers, and a few key settings can dramatically reduce your exposure. The whoami protection guide shows you exactly what to do.
