Fingerprint Protector

Fingerprint Protector helps you reduce cross-site browser fingerprinting—the technique websites and trackers use to recognize you without cookies.

HOW IT WORKS
• Injects privacy protection early on every page load (including iframes)
• Uses a stable, seed-based virtual identity so your spoofed profile stays consistent across tabs
• Rewrites HTTP Client Hints (User-Agent, Sec-CH-UA*) at the network layer to match your profile
• Optional blocking of known fingerprinting CDN hosts

KEY FEATURES
• Protection presets: Balanced, Maximum, Paranoid, Compatible
• Per-site rules: relaxed mode for video calls, or disable on specific sites
• Privacy score (0–100) with tips in the toolbar popup
• Modules: Canvas, WebGL, Audio, fonts, screen, timezone, media devices, speech, battery, performance, ClientRects, Permissions API, hardware APIs, Privacy Sandbox signals
• Right-click menu for quick site exceptions
• Keyboard shortcut to toggle protection (Alt+Shift+F)
• Local audit log and JSON export/import of settings
• Built-in relaxed rules for Google Meet, Teams, Zoom, Discord, and more

PRIVACY FIRST
All processing happens on your device. We do not collect, upload, or sell your fingerprint or browsing data. No analytics server.

COMPATIBILITY
Maximum and Paranoid presets may break some sites (video calls, strict WebRTC blocking, tracker blocking). Use Balanced for daily browsing or add a site exception.
