Browser Fingerprint & Privacy Test
Privacy & Identity Leakage Analysis
Websites use these hardware and software markers to track you without cookies.
Software & Environment
Hardware & Graphics
Tracking Signatures
Canvas Fingerprinting
Uses the HTML5 Canvas API to draw invisible shapes. Tiny variations in pixel rendering reveal your unique hardware profile.
Font Enumeration
Identifies the specific fonts installed on your machine. Specialized software like Photoshop creates highly unique font signatures.
Hardware Signals
Extracts data about your CPU cores, RAM estimates, and GPU drivers to build a rigid, non-deletable hardware profile.
Network Context
Combines IP-based location, local timezones, and language preferences to narrow down your physical identity and origin.
Stateless vs. Stateful Tracking
Most users are familiar with Stateful tracking (Cookies), which stores files on your device. However, Stateless tracking (Fingerprinting) uses your system's configuration as a permanent ID that works even in "Incognito" mode.
Cookies (Stateful)
Stored on your device. Easy to delete and block via browser settings or privacy extensions.
Fingerprinting (Stateless)
Uses hardware configuration. Hard to block as it relies on features needed for web display.
Key Takeaways
- Hard to Block: Most detection signals are essential for basic web functionality like screen size.
- Cross-Session IDs: Fingerprints persist even if you clear your cache or use private browsing modes.
- Noise Mitigation: Privacy browsers like Brave add "noise" to results to make them non-unique.
