It is impossible to operate without this support. I recently switched to a Light Phone for improved privacy relative to the iPhone and android phones, and without caldav I can't track my calendar. In the near future they plan to implement carddav too. Seems I won't get past the free account. I was planing on using the family account. it was a no brainer, until this!

Would like to use with Light Phone via Caldav. Please implement it. thank you

So frustrating.
Please tell me that it's on the road map.

I think CalDav is essential for cross platform integration. Please consider adopting this utility for use with Calendar.

I want to switch from Mailfence, but this is stopping me. If you've ever used Business Calendar for Android, you'll understand why no other Android calendar is satisfactory, including the Proton Calendar app.

I use proton calendar for my personnal use mostly through the android app. And I would like to use the android app to manage as well a second calendar for professional purposes that is hosted on a nextcloud server.

Currently I can only share a calendar as webcal (.ics), but I want to connect an external application to one of my calendars with write access.

Therefore real caldav support would be really cool. The released calendar should get an own user with own pass like it is possible with SMTP.

my experience with proton as user and developer would be better if we can have caldav support for Gnome calendar and thunderbird

We developers, need this asap. It is an essential piece for integration.

I would really like to sync my Calendar to the Thunderbird desktop application next to my emails.

is anything happening regarding this? i'd like to sync other calendars to my proton calendar (as a primary calendar app) but can't because proton doesn't support caldav.
that makes me rethink wchich calendar app will be my primary calendar app

Essential for anyone who wants to be able to use Proton Calendar for commercial work. The tool is not offering functionality for booking slots, so one has to go with tings like SimplyMeetme or Calendly and it's super inconvenient not to be able to integrate those tools.

I'm also very interested in Proton's CalDAV support. This could be useful for many users.

Yes please. It is a serious hindrance that I can't integrate Proton Calendar with my calendar clients. Perhaps there could be a security solution via the existing Bridge app?

My main calendar is on my self hosted nextcloud, it would be amazing if I could sync that with the Proton Calendar app. I mean, we can already connect and sync google, why not add caldav there as well?

The vast majority of students and professionals will not be able to choose their school/work email provider, and the vast majority of them will want their email and calendar to be visible in the same app. That isn't possible in Proton Calendar, though, at least without forwarding all of your mail to a ProtonMail address, which may not be possible for some users, and which is a pain for the rest. As a result, very few people in that bucket are going to use Proton Calendar even if they use ProtonMail for their personal email. Maybe you'll get a few retirees and serious privacy wonks, but you'll miss the normies.

The solution is interoperability with other mail clients, and you can only do that via widely accepted standards. CalDAV support is therefore essential for this app.

Impossible to de-google myself entirely if I cannot connect my proton calendar to my android preferred calendar app

Yes, CarDAV & CalDAV were never designed to be end-to-end encrypted.

But they are standards, and so far the best ones we've got.

The impossibility to connect my Proton Calendar with my calendar client of choice means in practice that I never use Proton Calendar (nor Proton Contacts). So, so far, they are useless to me.

I understand the privacy risk or hole. But I still prefer keeping my info in Proton's servers as in other data-hungry companies' servers.

Please support this feature! <3

Albeit Calendar making its way into the Mail desktop app, I have to remain on browser for Calendar as I need a standalone Calendar app that is accessible:

1. In parallel to the Mail app
2. One click away

This feature is absolutely critical for any proton calendar adoption worth talking about. Otherwise, proton will need to reproduce every feature themselves. By allowing CalDAV access, you can use your preferred client with all the features you like.
