Proton Calendar: Secure Events 4+

Performs the basics with reminders, good visualization, location, and making it recurring. Missing the ability to share a calendar currently, which is currently being worked on. This is a core function of a calendar though, and should integrate better with their email services, even if these functions are restricted to other working Proton users. I hate to rate something down for a service it openly declares is not currently implemented, this is pretty central to a calendar app and is currently keeping me from fully migrating to Proton Calendar. The app also needs additional security found on Proton Mail and Proton Drive where it allows for the use of a password/pin and/or biometric on startup. Looking forward to the updates, and of course I will update my review when things change.

edit: Thank you for the reply! I did not see sharing was an option since I primarily use the app on iOS. I will try it out from the PC see if I can share and then still update and use it from iOS. Not ideal, but at least a work around.

Thank you for your feedback and review! Auto lock for the app as well as the option to edit shared calendars are features we hope to add to the app in the future.

Note that sharing calendars collaboratively between Proton users is already possible in the Proton Calendar web client and Android app: https://proton.me/support/share-calendar-with-proton-users.

I am a Proton Unlimited subscriber because I love the platform and their commitment to privacy.

Pros:
-Simple/attractive UI
-Solid basic calendar features

Cons:
Requires a little extra effort and a few workarounds to tailor this calendar to your personal needs.

Birthdays:
-automatic Integration of birthdays from our contact lists is preferable here but still notably not an option.
Workaround:
-In the meantime, I just created a ‘Birthdays’ calendar and manually added each one myself.

US Holidays:
-Currently, there are a lot of holidays( of which I’m used to being alerted to via iCloud calendar) that are not included in this feature.
Workaround:
-I disabled Proton’s built in ‘Holidays’ calendar and created my own, manually inputting each one.

Thankfully, you can add calendars from other platforms via URL (note that these cannot be altered in the Proton app and this feature has its limitations as it is not updated or synced in real time).

Overall, Proton’s commitment to privacy and putting their users first as well as their continuous improvement to the platform, for the most part, alleviates any reservations I might have otherwise had. I didn’t mind putting in a little extra effort to tailor the app to my needs.

That being said, I hope they continue to listen to user feedback and implement new features sooner rather than later.

Hi! We appreciate the extensive and detailed feedback! Your suggestions have been noted internally to help our development team with prioritization when implementing new features.

I’m new to proton. I just signed up and am starting to migrate my email to proton. I am trying to use the calendar but I’ve run into an issue. If I receive calendar invites in my email that are an attachment (such as an ICS file), there doesn’t seem to be any way to add them to my calendar. From the proton mail app there is no “add to calendar “ button. From the calendar app there is no import that I can find which allows you to import a downloaded file, and in iOS when you try to use the “share” button the calendar is not an option. This means the only way I can find to add some invites to my calendar is to manually enter the information. Ideally an “add to calendar” button should be available from the mail app, and a share extension should be available so you can receive a file/invite into your calendar.

On the plus side: My wife and I are both migrating to proton, so it’s nice to be able to share the calendar with her and both of us to see the same events. I’m still new so as I use this more I can get a better opinion.

Hi! Thank you for your honest feedback. Unfortunately, at the moment, it is not possible to accept/decline calendar invites through the Proton Mail iOS app. Currently, in order to accept or decline calendar invites on an iOS device, you need to access Proton Mail through a web browser at https://proton.me/mail and open the invitation from there.

This option has been requested already and we have added your vote to it as well.
