YourInfo

Live Demo: yourinfo.hsingh.app

A privacy awareness demonstration that shows what information websites can collect about you through browser fingerprinting and behavioral analysis.

Features

• Browser Fingerprinting: Canvas, WebGL, audio, fonts, and more
• Cross-Browser Tracking: Hardware-based identification that works across different browsers
• Real-time Behavior Tracking: Mouse movements, scroll patterns, typing behavior
• Device Detection: GPU, CPU cores, RAM, screen resolution
• AI-Powered Profiling: Uses Grok AI to infer personal details from fingerprint data
• Interactive 3D Globe: See other visitors in real-time with CesiumJS
• Privacy Detection: VPN, ad blocker, incognito mode detection

Tech Stack

• Frontend: React + TypeScript + Vite
• Backend: Bun + Hono
• Real-time: WebSocket
• Globe: CesiumJS with OpenStreetMap tiles
• AI: Grok (X.AI) for user profiling (optional)
• Cache: Redis for profile caching and unique visitor tracking (optional)

Getting Started

Prerequisites

• Bun runtime
• Redis (optional, for caching)
• Grok API key (optional, for AI profiling)

Environment Variables

| Variable | Description | Required | |----------|-------------|----------| | PORT | Backend server port | Yes | | VITE_WS_PORT | WebSocket port for dev | Yes | | REDIS_URL | Redis connection URL | No | | GROK_API_KEY | Grok API key for AI profiling | No |

What Information Is Collected

Hardware

• Screen resolution, color depth, pixel ratio
• CPU cores, RAM (capped at 8GB by browsers)
• GPU vendor and model
• Touch screen capability

Browser

• User agent, platform, language
• Installed fonts
• Canvas and WebGL fingerprints
• Audio processing fingerprint
• Supported codecs and DRM

Behavior

• Mouse speed, acceleration, movement patterns
• Scroll depth and direction changes
• Typing speed and key hold times
• Tab switching and focus time
• Rage clicks and exit intent

Network

• IP address and geolocation
• Connection type and speed
• WebRTC local IPs
• VPN/proxy detection

Deployment

With nginx

server {
    listen 443 ssl http2;
    server_name yourinfo.example.com;

    location / {
        root /path/to/yourinfo/dist;
        try_files $uri $uri/ /index.html;
    }

    location /ws {
        proxy_pass http://localhost:3020;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }

    location /api {
        proxy_pass http://localhost:3020;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

With PM2

pm2 start bun --name yourinfo -- run server/index.ts

Privacy Tips

This demo is meant to raise awareness about online tracking. To protect your privacy:

1. Use a VPN to mask your IP address
2. Enable Do Not Track in your browser
3. Use privacy-focused browsers like Firefox or Brave
4. Install browser extensions to block fingerprinting
5. Disable WebRTC to prevent local IP leaks
6. Use Tor Browser for maximum anonymity
