Ghostery

Ghostery enables its users to detect and control JavaScript "tags" and "trackers" to remove JavaScript bugs and beacons that are embedded in many web pages which allow for the collection of a user's browsing habits via HTTP cookies, as well as participating in more sophisticated forms of tracking such as canvas fingerprinting.

[7] Additionally, Ghostery's privacy team creates profiles of page elements and companies for educational purposes.

When configured, Ghostery also displays the list of trackers present on the page in a temporary purple overlay box.

On February 22, 2016, the company released the EULA for the Ghostery browser extension, as a proprietary closed-source product.

The company said that Evidon's business model "was hard to understand and lent itself to conspiracy theories", and that its new monetization strategy would involve affiliate marketing and the sale of ad analytics data.

[26] Added from Cliqz after owning Ghostery, it uses a heuristic, AI approach to determine if those trackers are sending unsafe data.

Jonathan Mayer, a Stanford graduate student and privacy advocate, has said: "Evidon has a financial incentive to encourage the program's adoption and discourage alternatives like Do Not Track and cookie blocking as well as to maintain positive relationships with intrusive advertising companies".
