About Proton
Proton is a Swiss privacy company offering an end-to-end encrypted suite: Proton Mail, VPN, Drive, Pass (password manager) and Calendar. Everything is encrypted so Proton itself can't read your data.
Its appeal is a credible, private alternative to Google and Microsoft — no ads, no data mining, strong Swiss privacy law — with a free tier that most people can actually use.
