We recently partnered with JJ Snedden, a BSc Computer Science student at the University of Southampton. He heeded our continuous call for academic collaboration, making our data part of his research and development (R&D) project, “Improving Online Studying Routines to Assist or Develop Students’ Capabilities.”
“Projects like this resonate with our goal of making the Internet a safer and more transparent place. Mr. Snedden’s system can be crucial in providing a sound and safe external study environment to students and we supported it by providing accurate web categorization intelligence,” says our CEO and founder Jonathan Zhang.

Among those who recently heeded our call is Fergus Smith, a software development MST student at the University of Glasgow. He worked on a distributed multiplayer game aimed at educating Internet users about the prevalence of web tracking.
The project called “TrackerHunt” was developed as a Chrome extension that enables users to learn what specific websites are tracking them. WhoisXML API’s Website Categorization API helped deepen the web tracking insights by allowing users and researchers to see the categories the web pages that employ web trackers fall under.
