Sync contacts, calendars, and notes with native mobile apps
To sync with your cell phone and email - iphone calendar, contacts, and notes.

ProtonMail offers encrypted contacts for both web and mobile applications (https://protonmail.com/blog/encrypted-contacts-manager/). Calendar and note functionality will be released in the future.

If development on this feature was started NEARLY SEVEN YEARS AGO, how come it's still not available?!

From the 2022 announcement:
"Today we’re launching a new contacts manager, the first one in the world that includes both zero access encryption and digital signature verification."
What it more accurately might have said is:
"Today we’re launching a new contacts manager, the first one in the world that is marginally useful except for creating an email."
How about creating a bridge for Contacts so that any app that needs to pull or consult a contact can be channeled to PM Contacts instead of the stock Contacts app. Permissions would be up to the user based on threat model.
At the very least, give an estimate of completion date and a roadmap of expected functionality. At least!

Dying of curiosity to know when this feature will finally see the light. Please give us a hint

It is weird that the admin replied in 2018 about the encryption on contacts.
However, I think we are asking to have the sync on the contacts in mail to cell phone contact list. It is just like Google has the capability to sync the Google contacts to IPhone contact book.

Absolutely critical, unified inbox, calendar, and contacts or bust

Your response is not what we want. We want sync with the contacts app on phone.

6+ years later and it still hasn't been addressed. Are you a serious company, Protonmail? You really need to hire some team leads with time management skills, and focus on finishing core products before cranking out half assed new ones.

The current implementation of ProtonMail Contacts is lacking, a lot.....

Isolated "encrypted contacts" are really not enough as not in sync with the device's data. Happy that are encrypted, but if they are isolated, it doesn't fulfil the purpose.

Need badly to sync proton contacts into phones!! Currently proton contacts are USELESS

Have you ever considered partnering with GrapheneOS for even a better integration on this task. Both products and therefore us consumers would gain so much out of it...

Google One allows you to backup phone numbers and contacts, would be nice if ProtonDrive would let us to the same thing too

This feature request and the request to support CarDAV & CalDAV are likely duplicates: https://protonmail.uservoice.com/forums/932842-proton-calendar/suggestions/8985673-cardav-caldav-support

Proton Contacts is unusable in its current state. I am trying to move away from Google, but the lack of contacts sync with anywhere is a huge deal breaker. Come on Proton....it's not the 90s anymore!!!

Proton Contacts for the possibility to make calls directly is needed, import - export - sync, and maybe chat in the app would be fantastic.

I strongly disagree with this statement: "ProtonMail offers encrypted contacts for both web and mobile applications"
I will give you that it exists in some form, but it might as well not in its current state. It no where near functionally complete nor usable, especially on mobile devices.
Many things are lacking, such as functional contact cards.
Such as:
- not every contact card is for a person, sometimes it is for a business/organization (being able to use the "organization" field as contact name/title without duplicating to other fields)
- limit on how many email addresses are allowed to be entered per contact
- system integration/access (what use are contacts in Proton when you have to manage an entirely separate list on your phone and computer; what use is the Bridge when the contact list isn't accessible)On the web GUI, yes, access was made easier, but that is merely a quick access not a full fledged address book.
I suggest getting with the people over at Etesync. They managed to create encrypted contact and calendar with sync and system integration, so we know it can be done.
