If you are a ProtonMail or ProtonVPN user with a paid plan, you can start using the ProtonCalendar beta right now.
The event title, description, location, and participants for every event are encrypted on your device before they reach our servers, so that no third party (including ProtonMail) can see the details of your events. ProtonCalendar uses end-to-end encryption to keep all your events’ sensitive information private and secure. You can use it to keep track of your plans and appointments while keeping your data private. ProtonCalendar is the first fully encrypted calendar app. These companies snoop on your calendar and use that information to inform their advertising. For the longest time, to easily organize these events, you had to let large corporations monitor these special moments.
It’s a record of the moments that make up your life - your big meetings, gatherings with friends, and children’s birthdays.
