Ghostery enables users to
manage data collected about them as they navigate the web on mobile devices. The app detects trackers, web bugs, pixels, and beacons placed on web pages by more than 1,200 ad networks, behavioral data
providers and publishers. The app also enables users to learn about those companies, visit their privacy policies, learn of opt-out options and block scripts. The app's opt-in feature, GhostRank,
sends Ghostery servers information about trackers in order to improve the feature and report on online tracking. Users can download Ghostery anonymously, without providing registration
data.
