In this case, Proton Technologies provided the FBI with the “recovery and associated email addresses” of the user, which lead to his discovery.
Two years ago, RestorePrivacy ran an article on another ProtonMail logging case involving a French activist who was also a ProtonMail user. In that case, French police received the user’s IP address from Proton Technologies, leading to the arrest of the suspect.
In short, the answer is yes if you are looking for a secure, encrypted email service that does not have access to the contents of your inbox.
If you are doing things to attract the attention of law enforcement, then the data you provide when you use ProtonMail, such as IP address and recovery email, may be shared with authorities if Proton Technologies is legally compelled to do so in Swiss court.
so, yes, still secure and private
