Of course not. And unless I'm in the EU, I don't need it (and even then, not really, HotJar can be made GDPR compliant). HN will definitely balk at me saying that, but understanding UX is much more important than whatever philosophies one has about not tracking users. Because if you don't understand UX, there's no point to the debate about tracking vs not tracking users, because you won't have any users in the first place.
