Did you leave the door open?Free browser fingerprint & privacy test
Every website you visit sees this much about you. No cookies, no permissions, no consent banners needed.
Your browsing history
Websites cannot access your browser history. The old CSS :visited trick was patched years ago.
Your other open tabs
Tab isolation prevents websites from knowing what else you have open.
Your logged-in accounts
We cannot tell if you are logged into Google, Facebook, or any other service.
Your real identity
Nothing on this page reveals your name, email, or any personal identifier.
Your files or filesystem
Browsers sandbox websites from accessing your local files without explicit permission.
Your clipboard contents
Clipboard access requires a user gesture and explicit permission in modern browsers.
Your exact location
Geolocation API requires explicit user permission. IP-based location is approximate (city-level at best).
Your camera or microphone
Media device access always requires explicit user permission.
Your contacts or calendar
These system resources are completely inaccessible to websites.
Your passwords or autofill data
Password managers and autofill data are protected by the browser.
Use a VPN
Masks your IP address and approximate location from websites.
Enable Do Not Track & GPC
Sends a signal to websites requesting they don't track you. Not all sites comply, but it helps.
Use an ad/tracker blocker
Extensions like uBlock Origin block tracking scripts, ads, and fingerprinting attempts.
Use Firefox with Enhanced Tracking Protection
Firefox strict mode blocks fingerprinting scripts, cross-site trackers, and crypto miners.
Use Tor Browser for maximum privacy
Tor Browser standardizes fingerprint signals and routes traffic through the Tor network.
Reduce installed fonts
Custom fonts increase fingerprint uniqueness. System-default fonts reduce distinguishability.
Disable WebGL when not needed
WebGL exposes GPU information that contributes to fingerprinting.
Use private/incognito browsing
Prevents persistent cookies and storage between sessions (but does not prevent fingerprinting).
Keep your browser updated
Modern browsers add new anti-fingerprinting protections regularly.
Review extension permissions
Some extensions can read all page data. Audit what you have installed.
