For iOS, this is not a limitation of Proton, but of Apple. Apple does not allow you to change the default calendar app on iOS (yet).

Integrating with the Android calendar API should not really have any security impact as it's a local access API. For example EteSync implements exactly that and doesn't even provide its own user interface for the calendar. Without system integration, the experience doesn't really match up to Google Calendar.

Just gave this 3 votes as it is critical to me. Would really benefit from having all my events and schedule on one calendar that is integrated into android.

To elaborate on this, the reason why you can't select Proton as the default calendar is that the calendar is managed through the app. In order for, at least on android I don't know about IOS, the calendar to be able to be selected as default Proton needs to open the calendar to be able to be signed in through a "less Secure" platform such as the phone instead of through the app. All that being said I 100% support this change. Proton please consider this!

Allow proton calendar settings to set proton calendar as the default calendar app in ios

When will it be possible to set Proton calendar as default on iphone?

+1

Proton Calendar must be able to be set as the default calendar.

This is important for apps that integrate with the Android calendar API. App categories like task managers (Google Tasks, TickTick, Taskito etc.) query the user calendar and add calendar events in-between the tasks.

Taskito does it in their daily timeline view.

Adding this possibility to the app would also enhance the user experience across apps in general.

I'm surprised this hasn't been implemented yet. I just scheduled a doctor appointment on my android phone and the medical app gives me an ics file with the appointment time. I open the ics file and it gives me the option to import on all calendar apps I have, except proton calendar. This is the main reason I'm not using the calendar service yet.

I was looking for that today to no avail. Alternatively, one or two other widgets to choose from would also be good

Das habe ich heute auch vergeblich gesucht. Alternativ ein oder 2 andere Widget zu Auswahl wäre auch schon mal gut

I regularly get cal invites with attached ics files from various other services. Mostly Google, but some Office 360 accounts as well. ProtonCalendar should register for these events directly from the ProtonMail message.

Add .ics file association option for the Android ProtonCalendar app.
E.g.: When tapping on an .ics file, choose to open with ProtonCalendar app, just like it is possible with Outlook.

In the Web UI it is possible to import .ics files under "import calendar". Would be cool for an app to be associated with .ics files when trying to opening them (regardless of OS).

thanks in advance, I'm sure you're working on this already.
Give upvote if you find this feature more important, too.

Totally agree. They open by default in the Google calendar app, and I can't seem to change the settings for so the proton mail app will open ICS files.

Having the Proton Calendar Android app register as a handler for .ics-files and importing them would be a huge productivity boost.

Right now, I can either import them via the web interface or create them manually, none of which suffice of the go.
