  Data Mirror — See the invisible web tracking you in real time.
  
  Every website you visit triggers dozens of hidden trackers, data brokers, and ad networks collecting your browsing habits, interests, location, and device fingerprint. Data Mirror makes it all visible. And with Loki mode, you can fight back.
  
  LOKI MODE: FIGHT BACK
  Tired of being watched? Activate Loki mode and turn the tables. Instead of just observing trackers, Loki feeds them fake data: corrupted fingerprints, fabricated user profiles, poisoned ad events, and misleading consent signals. Your real data becomes invisible in a sea of noise. Trackers still collect, but what they get is worthless.
  
  PRIVACY SCORE (A→F)
  Get an instant privacy rating for every site. See how many trackers are active, where your data goes, and how exposed you are.
  
  REAL-TIME DATA VALUE
  Discover what your browsing data is worth on the ad market. Watch your estimated value grow as trackers collect more about you.
  
  WHERE YOUR DATA GOES
  See which countries receive your data. Get alerts when data leaves the EU to Western or concerning jurisdictions.
  
  1000+ TRACKERS IDENTIFIED
  Detects trackers from 38 Big Tech companies and 24 known data brokers. Every request is analyzed and categorized.
  
  30-DAY HISTORY
  Track your privacy exposure over time. Export your data as JSON or CSV for your own analysis.
  
  
  Loki mode includes:
  Canvas, WebGL, and audio fingerprint spoofing
  Fake geolocation, timezone, and language signals
  Realistic fake ad events injected into Google Analytics, Meta Pixel, and GTM
  Tracker cookie corruption and storage ID rotation
  Consent signal pollution (Google Consent Mode v2, CMP cookies)
  Built-in whitelist to protect your work tools (Google Workspace, banking, auth)
  
  One click to activate. One click to deactivate. No page refresh needed.
  
  
  PRIVACY BY DESIGN
  100% local processing. Zero data collection. No account required. No ads. Free forever. Made in France.
