About ProtonMail
ProtonMail is an end-to-end encrypted email service developed by Proton AG in Geneva, Switzerland, available on web, Windows, Mac, Linux, iOS, and Android. All emails are encrypted on Proton's servers using PGP, meaning even Proton cannot access the contents — only the recipient's private key can decrypt messages. Switzerland's strict privacy laws and Proton's independent jurisdiction from US and EU surveillance programmes make it a legally strong choice for sensitive communications. The free plan provides 1 GB storage and one email address; Proton Unlimited adds custom domains, aliases, Proton VPN, Proton Drive, and Proton Calendar. ProtonMail is used by journalists, activists, legal professionals, developers, and businesses handling confidential communications who need email that is both technically and legally resistant to unauthorised access.
