Does anyone know how private ProtonMail is? I heard admittedly crackpot-sounding rumors that it was some sort of NSA honeypot, but verifying them seems like proving the existence of a divine being.
Proton's encryption provides privacy by default - we cannot access any of the email content, email attachments, calendars, files stored on Proton Drive or passwords, 2FA codes, notes etc. on Proton Pass, and therefore cannot share any of this with any third parties.
We have also discussed such baseless claims of connections to NSA with our users on multiple occasions, including here: https://www.reddit.com/r/ProtonMail/comments/14demhj/debunki....
I mean after the Crypto AG / Project rubicon came to light (let alone many of the disclosures since) I don’t think you can rule it out - but at least it’s unlikely your data is for sale /being actively used against you for commercial purposes
