Encrypted email services, Proton Mail, announced a new feature for the Proton Calendar which enable people to share their calendars directly with anyone who uses Proton while simultaneously keeping the end-to-end encryption intact. This gives greater control over who can access or edit the calendar.

The end-to-end encryption ensures that only those who are invited are able to edit shared events and people can revoke access at any time without affecting anyone else on the team.

People can now open event invites from any app in Proton Calendar for Android and the .ics files can now be opened directly in the Proton Calendar app instead of opening on the website. This ensures that all events are imported directly to the Proton Calendar app and seen in one place, across devices.

This feature will be particularly useful in the workplace where scheduling meetings and coordinating projects can be a hassle for some. When everyone shares their calendar, anyone can find a time that works for the whole team at just a glance.

People can also share calendars directly with people who use other calendars like Google Calendar but then you will have to part with the end-to-end encryption meaning that your privacy and security will be compromised.

Proton Calendar lets your family view the upcoming events at a glance while preventing any third parties from accessing the sensitive information.

Switzerland-based Proton Mail is known for its focus on privacy and security, and the new sharing feature is no exception. By allowing people to share their calendars directly with anyone who uses Proton, the company is ensuring that sensitive information is protected from prying eyes.

This update is the latest in a series of improvements to the Proton ecosystem currently comprising Proton Mail, Proton VPN, Proton Calendar and Proton Drive.

“Your calendar is far more than a list of appointments, it’s a record of your life and is some of the most sensitive information you have. That’s why we want to be able to make the use of private alternatives to Gmail and other Big Tech services as seamless as possible,” said David Dudock de Wit, growth and product lead, Proton Mail.
