Proton Mail is famous for its privacy and security. The cool trick they do is that not even Proton can decode your email. That’s because it never exists on their systems as plain text — it’s always…
And Gmail can retrieve your mails from proton using IMAP. It’s even in their own (proton’s) documentation.
I don’t think it can. Where in the documentation did you find that?
An online search brought me here : https://www.getmailbird.com/setup/en/access-protonmail-com-via-imap-smtp which did looks like a documentation page about how to do exactly that. Obviously, it has nothing to do with them, and the actual details makes no sense the lower you get in the page. I’ve been had :)
They still can see most mails transit from their service in plaintext in both directions, though, which remain a privacy issue, but it has more to do with email protocols than anything.
