Events received from people who use other calendars are secured with zero-knowledge encryption. In both cases, event details, including the title, description, location, and people invited, are encrypted so not even we can see them. Proton Calendar makes staying on top of your schedule simple while keeping your information secure. Proton Calendar was built by the team behind Proton Mail, the world’s largest encrypted email service. Over 50 million people and some of the world’s largest organizations have signed up with Proton.
