What is Proton Calendar?
Your schedule is worth protecting
Your calendar is a record of your life. Proton Calendar helps keep it private.
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.
All the features you expect, plus privacy
Proton Calendar makes staying on top of your schedule simple while keeping your information secure.
Free calendar
Everyone has the right to privacy, which is why we make Proton Calendar available for free. To access more features and support our fight for a better internet, upgrade to a paid account.
Your data, your rules
Proton Calendar is a calendar that respects privacy and puts people (not advertisers) first. Your data belongs to you, and our encryption ensures that.

No comments or reviews, maybe you want to be first?Said about Proton Calendar as an alternative
Deivedux ProtonCalendar may not be as feature-rich as Google Calendar, but their main focus is protecting user data with end-to-end encryption. The free plan is enough for basic calendar functionality, but paid subscriptions give extra benefits for supporting their business model, as that's their only source of income.
