Proton also notes that it never finds out who you've invited to an event, and it allows for inviting people outside the Proton ecosystem, letting people "cryptographically verify that it was you who invited them."Īndy Yen, CEO of Proton, said in an interview with Wired in May that calendars are an "extremely sensitive" record of your life and that protecting them is essential. The web app version of Proton Calendar is open source, with the code for mobile apps to come next, Proton says. Proton Calendar is pitched as offering encryption for all event details, as well as "high-performance elliptic curve cryptography (ECC Curve25519)" to lock it. Our mission is to create an Internet that serves you and doesn’t require you to hand over your personal data to governments or corporations.Proton Calendar, which claims to be the "world's only" calendar using end-to-end encryption and cryptographic verification, has arrived on iOS, giving those seeking a more secure work suite an alternative to Google, Apple, and the like. And soon, you will be able to privately save and share documents to the cloud with ProtonDrive. A calendar app has been one of our most requested products-pairing a secure calendar with a private inbox dramatically increases the utility of both. ProtonCalendar is just the latest project in our mission to create a more private Internet.

Even in the unlikely event of a breach, your agenda will remain secure. It does this by keeping the details of all your events encrypted while they are stored on our servers. For our users with heightened security needs, ProtonCalendar will prevent authoritarian regimes from seeing who you are meeting with and what you are doing. Our calendar stops private companies from spying on your schedule.

It uses the same end-to-end encryption that ProtonMail does, ensuring that no one, not even ProtonMail, can access your schedule except you. With ProtonCalendar, you can now quickly arrange your life and plan your events in a convenient, secure way.
