It is keeping track of that and saving it on localStorage. Can you check? Maybe it is bugged.

So I just switched back to Firefox last week and it says I have clicked Primal 5 times and a bunch of others less than that which I guess is probably true. But when I went back to Safari which I was using previously there wasn’t anything in localStorage. Was this feature added recently?
Clicking in Safari now does add them to localStorage so it’s not broken.
