🎯 Your Browser Identity Across Apps

Based on your device's characteristics, we've created a unique ID for you. Try opening this page in different browsers (Chrome, Firefox, Safari, Edge) on the same device to see if you get the same ID!

✨ What Makes Your Browser Unique

🔬 Your Browser Details

Below is all the information your browser shares. Some of these (like GPU, Audio, and Canvas) create unique "fingerprints" that can identify you across different browsers on the same device!

🛡️ Want More Privacy? Here's How!

✨ Tor Browser: Makes everyone's browser look the same - you blend in with millions of users
✨ Brave (Strict Mode): Adds random variations to make your browser harder to identify
⚙️ Firefox: Enable privacy.resistFingerprinting in settings for better privacy
💡 Good to know: Just switching browsers won't change your device's unique characteristics!

🧪 Educational Tool: This page shows you how different browsers can be identified on the same device using various signals. Everything is stored locally in your browser - nothing is sent to any server!

🔬 How It Works: We collect various "signals" from your browser and device:

Hardware Fingerprints: GPU signature (WebGL), audio processing characteristics, screen specs - these stay the same across all browsers
Canvas & Audio: How your device renders graphics and processes audio creates unique patterns
Battery & Network: Real-time info (note: many browsers block battery for privacy)
Capabilities: What features your browser supports

📊 Accuracy: Hardware-based signals (GPU, audio, screen) are very accurate for cross-browser tracking. Software signals (user agent, fonts) can differ between browsers but still contribute to uniqueness.

🔒 Privacy Promise: All data stays in your browser's localStorage. Nothing leaves your device. You can verify this in DevTools → Network tab (there should be no requests!).
