I am already a paid proton user, but do not use proton mail much, as I need an integrated calendar, so I can ditch Google entirely. A very flexible contact manager and then <Notes> would be a lovely bonus.

contacts and calendar much needed features, I am planning to become a paid user soon, since I can switch from the Gsuite with these added! In priority (for me) it is Contact sync (carddav), calendar sync (caldav) and notes. This last one is not a blocker but would like to have it as well!

Contact syncing is planned - see https://protonmail.uservoice.com/forums/284483-feedback/suggestions/7158338-carddav-server-for-contacts-synching-contacts

Please close this as a duplicate.

I really miss Google Calendar, but obviously I am afraid to use it. My paper diary is very secure, but it does not email me reminders.

If ProtonMail were able to provide secure contact and calendar integration, it would become my default service instead of Google. I also use an electronic task manager ("To Do" list) and would be happy to see such functionality included in the development roadmap.

I would be willing to pay an annual subscription fee to sustain the development and ongoing support of such functionality.

Calendar and contacts management (includind synch of course) would be a great plus and would bring many people from other - not protected - services.
10 votes just on this !

Better Folder management, calendar, and the ability to paste in a screen shot.

Just one word: CONTACTS
Paramount option to have a usable service 4everyone

Contacts and Calendar options would be great. Currently using my own Nextcloud to avoid google as much as possible.

Contacts sync please so we can ditch other providers! (calendar is more for business but contacts is for everyone, have to be able to call my wife :)

If they will sync it with mobile then it will create a problem. SO maybe different apps would be good idea. I also need this feature.

What? does this even mea?

I don’t think this would be a good idea. It would defeat ProtonMail purpose, which is SECURITY & PRIVACY. A workaround for this, would be a ProtonMail Calendar and Contacts Add Ons

This feature would be a nice alternative to the Google stuff, i miss a trusted secured calendar app. Proton could be a leader in trusted app. I would love to see a partnership with eelo.io

+1 for calendar and contacts can be edited on the phone

Calendar would be amazing! I'd prioritize that over notes or chat. It was hard enough to get people on Signal — and the secure chat app market is becoming oversaturated — so I don't understand the requests for sms/mms.

Absolutely no! Why!? Because it slows down server and will cause a lot of security threats! Where are reason for sync? Your unsecured stuff not going to be more secured or priority, because it's still on other unsecured devices, somebody's memory!

I would use all 10 of my votes for this if I could. I support most of the reasons others have explained - security, convenience of having everything in one place. Calendar, TASK LISTS, Contacts and Notes would be amazing. If they could work together even better: having the option to have a task deadline appear on the calendar or if you have an appointment to call a contact it would be great to have the contact information within the expanded appointment. Total integration would be so sexy.

We need a calendar because Google does not respect our privacy: it has our contacts and reads our activities to send us publicity.
