Visualize and, optionally, block the invisible websites that track you.
Thousands of companies and organizations secretly collect your personal data when you use the web, creating a shadow web of connections between sites you go to and trackers you probably never heard of. Collusion for Chrome graphs the spread of your data from sites to trackers, in real time, to expose and, optionally, to break these hidden connections.
Instructions: Browse the web as usual. The toolbar icon will animate if the graph changes. Click the icon to see the graph. Click *Block known tracking sites* to prevent tracking. Or watch the embedded video.
