Ghostery for Firefox also available.After showing you who operates behind the scenes, Ghostery also gives you the opportunity to learn more about each company it identifies, including links to their privacy policy and opt-out options.Ghostery allows you to block scripts from companies that you don't trust, delete local shared objects, and even block images and iframes. Ghostery also includes the optional, opt-in feature called Ghostrank, which sends Ghostery servers anonymous information about the trackers you encounter and where you encounter them. This allows us to create a more comprehensive list of detectable items, and helps us create a more transparent behavioral advertising ecosystem through our partnership with Evidon.Ghostery is built and maintained for users that care about their online privacy, and is engineered with privacy as a primary goal. Ghostery use is anonymous. No registrations or sign-ups are required. The Ghostery plug-in does not place cookies into your browser. Neither the Ghostery application nor Evidon receives any data from Ghostery users unless the user opts-in to participate in Ghostrank. Ghostrank data itslef is anonymous, is NEVER used for advertising targeting purposes, and is only shared in aggregated, non-personal, statistical form.
