GhostRank sends anonymous statistical information about the trackers, ads, and other scripts that Ghostery encounters and the pages on which they're found. It does not make use of browser cookies or flash cookies and stores no unique information about the user (not even an IP address).

Ghostery uses this information to create panel data about the proliferation of these scripts and shares this data with the Ghostery community, companies interested in measuring their own activity and compliance with privacy standards across the web, and organizations dedicated to holding these companies accountable. GhostRank data is not used to target advertising and is never shared for that purpose. For more details on exactly what GhostRank collects, please visit our FAQ.

By participating in GhostRank, you're agreeing to become part of this anonymous panel and you're helping to support Ghostery as you browse the web.
