Proton Mail
End-to-end encrypted email from Switzerland. Zero access to your messages — even Proton can't read them. Open-source, audited, used by journalists and activists worldwide. Messages between Proton accounts are encrypted end to end automatically, without either side configuring anything.
Not sure how to add Proton Mail to your home screen? Step-by-step for Chrome, Safari, Firefox and Edge — it takes about ten seconds, and there is no app store involved.
