### Make every day safer with end-to-end encryption

Proton Calendar automatically secures all your events with end-to-end encryption. 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.
