Website user behaviour tracking, see their website.
This is another analytic(I mark them with "online tracking") and it did a better than usual job of explaining what it does- until it got to it's privacy section.
The policy only covers the use of the site- not the analytic. Strangely enough on their pages they don't even use their own service. They use Google Analytics. Huh?
It appears that someone filled out a wrong form they downloaded somewhere to make the policy. It is a common mistake.
The tools from hotjar.com do track a user's behavior at least while the user is moving around the site. I've looked at their Linkedin page https://www.linkedin.com/company/5265084?trk=tyah&trkInfo=idx%3A1-1-1%2CtarId%3A1425125769720%2Ctas%3Ahotjar and Facebook page https://www.facebook.com/HotjarApps and they seem to only be interested in providing tools for website owner to use to analyze how visitors are using their site. The goal would be to arrange the site to make it vital enough to visitors to convert them into paying customers, but that isn't particularly evil. They don't track you for the purposes of collecting personal info, selling info or placing ads.
