Ghostery is supported by Ghostrank, our 100% opt-in feature that collects information about the trackers you see and the sites on which you see them. Our parent company, Evidon, packages that information and sells it back to sites who use it for privacy, performance, and security audits; and also ad tech companies who use it for competitive intelligence about each other.
That information is totally anonymous - it's all intelligence about the tracking industry, none about our users. And Ghostery works exactly the same whether you choose to share that with us or not.
We hope you'll opt-in, but we're committed to delivering a good product for user transparency whether you choose to or not.
