“Where ProtonMail is really looking to differentiate itself is by putting privacy at the heart of Proton Calendar.” VentureBeat

A calendar is more than just a tool. It’s a record of the moments that make up your life. Proton Calendar is an encrypted calendar that lets you keep your life private, away from prying eyes and tech companies that spy on you.

With Proton Calendar, you no longer share your private life with your calendar provider or other third parties — only you have access to your appointments, meetings, and events. Proton Calendar uses end-to-end encryption to keep all your personal information private and secure so that no third party (including Proton) can see the details of your events.

Proton Calendar syncs across devices, so you can keep track of your schedule anywhere. It also works both online and offline.

Tens of millions of people use ProtonVPN and ProtonMail, the world’s largest encrypted email service. Proton Calendar brings the same privacy protection to calendar.

Unlike other popular calendar apps, we can’t spy on your activities and misuse your data.
✓ No ads, no trackers, and no data sharing with any third parties
✓ End-to-end encryption — even we cannot view your event details
✓ Zero-access encryption — event names, descriptions, and participants are fully encrypted and inaccessible to third parties
✓ Based in Switzerland — All your data is protected by Swiss privacy laws

Proton Calendar is designed to help you stay better organized.
✓ Manage up to 20 calendars. Perfect for organizing your calendars for work, family and friends.
✓ Create, edit, view, and delete events
✓ Add emojis to an event 🚀 🙌
✓ Set recurring events on a daily, weekly, monthly, yearly, or custom basis
✓ Schedule appointments in both local and foreign time zones
✓ Add locations and descriptions to each event
✓ Add multiple notifications to any event
✓ Automatic sync with Proton Calendar web app and access your calendars on any browser and any device
✓ Dark mode and light mode

We’re community-supported, open source, and committed to transparency.
✓ Funded by users, not advertisers — privacy is our business model
✓ Built by scientists and engineers from CERN and MIT
✓ Used by high-profile journalists and organizations globally
✓ GDPR and HIPAA compliant
✓ Hosted in Switzerland and protected by some of the world’s strongest privacy laws

Building an internet that puts people ahead of profits
Proton Calendar is developed by the same team behind ProtonMail. Created by scientists who met at CERN, Proton’s mission is to build an internet that puts people before profits. Our tools protect millions of journalists, professionals, businesses, and ordinary citizens around the world.

Over the course of the beta, many additional features (event invitations, etc.) will be added, and your feedback will be incorporated.
