Data Mirror is a free Chrome extension that reveals the hidden economy behind every website you visit.
Every page load triggers a real-time ad auction where your browsing data is sold to advertisers — without your knowledge. Data Mirror makes this invisible market visible.
🔍 WHAT DATA MIRROR SHOWS YOU
- Privacy score A→F for every website
- All trackers detected (advertising, analytics, fingerprinting)
- Big Tech presence: Google, Meta, Amazon, Microsoft and 35+ others
- Data resellers and brokers actively trading your profile
- Countries your data is sent to — with GDPR risk assessment
- Estimated market value of your data per visit and over 30 days
- "You should have earned this" — your cumulative data value
💰 YOUR DATA HAS A PRICE
The average user generates $4–12/day in browsing data value. You receive none of it. Data Mirror shows you exactly whats being sold, to whom, and what its worth — based on FTC reports, Cracked Labs research, and IAB RTB studies.
🔒 100% LOCAL — ZERO DATA COLLECTION
- All analysis happens entirely on your device
- Nothing is ever sent to our servers
- No account required, no sign-up
- We dont even have a server that collects user data
- Privacy by design — Made in France 🇫🇷
📊 WHAT GETS DETECTED
- 1,000+ known tracker domains
- 38 Big Tech companies
- 24 data resellers and brokers
- Real-Time Bidding (RTB) auction signals
- Cookie sync and fingerprinting attempts
- High-risk country data transfers
📤 EXPORT YOUR DATA
Export your privacy audit as JSON or CSV — current page or full 30-day history.
Unlike ad blockers (uBlock Origin, Privacy Badger, Ghostery), Data Mirror doesnt block trackers by default. It shows you the truth — transparently, locally, and for free.
