About DataLeaked.site
What is DataLeaked.site?
DataLeaked.site is an educational platform designed to demonstrate how much information your browser and device can reveal about you, even when you think you're browsing privately.
Our goal is to raise awareness about online privacy and help users understand the extent of data collection that happens during normal web browsing.
Why We Built This
In today's digital world, privacy is increasingly under threat. Many users are unaware of how much personal information they're sharing simply by visiting websites.
By showing you exactly what data your browser reveals, we aim to empower you with knowledge and tools to protect your privacy.
- Educate users about online tracking methods
- Demonstrate the power of browser fingerprinting
- Show the extent of data collection in real-time
- Provide insights into privacy protection methods
- Raise awareness about digital privacy rights
How It Works
Our website uses various web APIs and techniques to collect information about your device, browser, and network connection.
All data collection happens locally in your browser — we don't store any of your personal information on our servers.
Browser Fingerprinting
Collects information about your browser's unique characteristics, including installed fonts, plugins, screen resolution, and rendering capabilities.
Device Detection
Identifies your device type, operating system, hardware specifications, and available sensors and capabilities.
Network Analysis
Analyzes your network connection, performance metrics, and security status to build a profile of your internet usage patterns.
Location Tracking
Demonstrates how websites can determine your approximate location through various methods, including IP geolocation and browser APIs.
Privacy & Security
We take privacy seriously. Here's what you need to know:
- No Data Storage: We do not store your analysis results on our servers.
- Local Processing: Fingerprinting and scoring run in your browser. Results stay in localStorage on your device.
- Optional third-party contact: Some tests (WebRTC STUN, optional public IP lookup, DoH probe) contact third-party servers only when you run them. Optional privacy-respecting analytics may be enabled by the operator. We do not sell data or run advertising pixels.
- Educational Purpose: This site is designed purely for educational purposes.
- Open Source: Our code is available for review and transparency.
