Ghostery for Chrome, Firefox, Edge, Opera, Safari, and Android sees the "invisible" web, detecting trackers, web bugs, pixels, and beacons placed on web pages by Facebook, Google Analytics, and over 1,900 other ad networks, behavioral data providers, web publishers - all companies interested in your activity.
It 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 opt-in allows for creating a more comprehensive list of detectable items and helps create a more transparent behavioral advertising ecosystem through the partnership with Evidon.
Ghostery for Chrome, Firefox, Edge, Opera, Safari, and Android is built and maintained for users that care about their online privacy and are engineered with privacy as a primary goal. Neither the Ghostery application nor Evidon receives any data from Ghostery users unless the user opts-in to participate in Ghostrank. Ghostrank data itself is anonymous, is NEVER used for advertising targeting purposes, and is only shared in aggregated, non-personal, statistical form.
