If you go pro, of course, you have to share payment information, but you don't share it with CoSo directly -- there's a third party site that handles it. There isn't even a mechanism here to edit your pro membership. You have to log into the other entity to do it. Your credit card info and name don't flow here.
@AlphaCentauri @Former5SportOfficial thanks for the knowledge. Appreciate it.

You know yourself what information you had to give -- an email address, and of course the IP address you log in from, if you don't use a VPN. People may share more, but you aren't required. And with no advertisers, there's no need to track your browsing habits to serve you ads.
