Protonmail the most famous 'private' email provider. I knew them from MR. Robot show (lol) but as media taught us, not all we see is true in movies. We all have heard about how ProtonMail logged IP address of French activist and how it's clearly stated in their privacy poilicy that they DO NOT log IP(s) but hey it turned out to be a lie so yes all i can say is protonmail sucks and you should stop using it (also use fucking tor browser to mask your IP)and do not trust privacy polices so easily next time. so main takeaway from it is that do not trust privacy polices or comapnies easily even if they are pretending to be a privacy friendly company
