We rely on the Ghostery users who opt-in to share their anonymous information about the data collection technologies they see, and where they see them. We take that information, add our analysis, and use it to build products that help companies to audit and manage their relationships with these marketing and advertising technologies . This empowers these companies to improve the performance, security, and user experience of their websites. None of the information we share is about our users, nor is it stored in a way that could be used to trace back to our users.
You’re opted-out of sharing your data by default, meaning you can use Ghostery without sharing anything with us, if you'd prefer. (But please opt-in. It is how we keep Ghostery free and continue to make it the best tool out there!)
