ProtonMail released encrypted calendar: How to access it in beta?

ProtonMail, a name becoming increasingly synonymous with digital privacy in recent times, has launched a new encrypted calendar app in beta, ProtonCalendar. According to the company, no third-party (including the ProtonMail itself) can access the private data that you save on the calendar. The service uses end-to-end encryption to keep the private data safe so that you can go about in your life without worrying about privacy.

Currently, ProtonCalendar is available only on the web version but will be released for the Android as well as iOS users soon.

The company claims that this is the most secure calendar to date. In another blog, ProtonMail has explained the security model of the calendar and why it is so secure.

What makes ProtonCalendar secure?

Users will have a set of permissions allowing them to perform set tasks such as edit events, view event details, check out the member list, among others.

For every calendar, there will be a calendar key (ECC Curve25519 PGP key) which will then be systematically encrypted with a randomly-generated 32-bit passphrase. Once this process is done, the calendar key will be stored on the ProtonCalendar backend server.

Thus, each member will possess a copy of the passphrase that is encrypted and signed with their primary address key. This signature will ensure that any third-party cannot meddle with the user’s data.

How to access encrypted ProtonCalendar?

To access the ProtonCalendar, you will have to sign in using the ProtonMail Version 4.0. Currently, the beta version of the calendar is available only to the paid users, and the free users can access the ProtonCalendar once it is publicly released.

While the basic version will be available to all users upon release, the paid ProtonMail users will get some additional benefits.

“We believe everyone has the right to plan dinner with friends without announcing to Google who will attend,” ProtonMail mentioned in their announcement.

How to send feedback?

You can also send feedback as well as suggestions and bug reports if you’re using the beta version of the calendar. Click on the username at top right corner and then select the Report a bug option as shown in the screenshot above.

The privacy issue is no joke, and we should make sure that it remains intact. ProtonMail and its services provide a better way to make sure that our privacy remains protected.
