Ok sorry but I'm now really considering moving to Tuta (similar privacy-friendly mail and calendar service) just because of this 10 years missing feature. Cmon developers!

To be honest, I'm not sure how frequently developers monitor these forums, but I truly think the only thing preventing people from doing a mass overnight exodus from Google to Proton overnight is lack of CalDAV support and any basic Google calendar features being paywalled by Proton. Besides the calendar, making proton my main client has genuinely improved my quality of life and experience using the internet, but this incompatibility with calendars is incredibly frustrating, and at this point, it feels unworkable and unreasonable for only this calendar to not being compatible with mainstream calendar clients.

tldr; please find a way to accommodate CalDAV support; the lack of integration of proton calendar into my existing tech ecosystem is unsustainable thanks for all your work :))!!!

literally begging for caldav support

Need this!

here here, this is essential, please support basic integrations

It's been ten years and I've been following this for four... come on Proton. I don't like being locked out of integration of my calendar with my self-hosted services.

Its really essential.
Niagara Launcher is half as good without caldav.

Missing standard integration makes this a vendor lock dead-end.

It is VERY annoying they don't provide these essencial features, because of "boo hoo security"

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
