What are Trackers?
We live in a connected world. When you browse the web, your data leaves a digital footprint that is connected by tracking technologies that help companies build a profile about you. By serving you targeted advertisements, companies can analyze ad and site performance and connect you to site functionality like comments and social media. This profile details how you interact with their sites and those of their competitors, allowing them to optimize communications and site experience to reach you - and others like you - at the right place, at the right time.

Spring has sprung and with it an updated version of Ghostery (v 7.2) is ready for the masses! This release includes a number of number of big improvements and changes, so continue on to learn more.
First and foremost, Ghostery 7.2 includes our first official unveiling of the Human Web. The Human Web is a revolutionary technology developed by Cliqz, our new parent company, that uses the wisdom of the crowd to power a sophisticated suite of browsing tools, including private search and heuristic anti-tracking. The Human Web does this by aggregating anonymous statistical data from our users to determine the relevance and safety of trackers, websites, and search queries. This data is thoroughly scrubbed of any personally identifiable information and is passed through a series of peer-to-peer proxies, making the data virtually unidentifiable by anyone, including ourselves, so that even if our security were breached by a hacker or outside organization, there would be practically no way to tie this information to individuals. The Human Web, which is open source (check out the code), is implemented in all new installations of Ghostery, though users can easily opt out of it at any time. This implementation of the Human Web is the first step towards bringing heuristic anti-tracking - that is, an anti-tracking feature that uses machine learning to improve itself - to Ghostery in addition to our traditional block-list model, a move that will greatly increase the privacy firepower of our product.
Beyond implementing the Human Web, Ghostery also features a handful of new features and improvements. Chiefly, we have made all advanced features - including slow and non-secure alerts and URL patterns - available to all users, even those without accounts. This is our first step in making as much of the Ghostery experience available to users without needing to share an email address or create a password. Additionally, we have added a page speed indicator to the main panel, which shows the load time for the page. This indicator is a great way to see the impact that blocking or not blocking trackers with Ghostery has on how quickly websites load. Further, we have not only made a myriad of bug fixes as we always do but we have also made a number of improvements to our back-end processes that speed up the performance of Ghostery while reducing the CPU usage.
Finally, we are building a rigorous A/B testing back-end into our product which will allow us to more quickly and aggressively test new features in the product. This means that users like you are more likely to see experimental new features live and in the wild, giving us a greater opportunity to test big ideas and get immediate feedback on them from real users like you. This will be especially true for our beta user group, which has access to early builds that we will be using more and more frequently to test some pretty ambitious ideas. Per usual, if you want to join this group, feel free to do so by following this link and signing up.
