This was "Started" (and planned: https://protonmail.uservoice.com/forums/284483-proton-mail/suggestions/32521357-sync-contacts-with-phone-address-book) for years now. It has some of the highest vote totals (especially if combined with the above link).
I agree with "T", why has there been no status update?
Why not just a blog post or something even if it's just a couple of paragraphs saying that this was a lot harder than thought and we're x months/years out. Then just apply updates to that post as things progress.

Before 'selling out', Skiff had this capability and it's only a matter of time before a PM competitor provides these options and steals PM market share. I've been a long-term paying PM user and really like it but this has me watching for alternatives. Please address this ASAP.

Please give an status update

Still waiting...

im sorry whaaaat?!?
cannot believe this feature wasn't done BEFORE 2018. Stunning lack of commitment to Proton's user base! without this the user experience is terrible, and destroys Proton's entire value prop. Get it done ASAP or I'm outta here Proton. ffs

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.

more and more desperate ... i came from google some years ago and i am disaapointed after all this years of waiting without contact synchronization and without information about a release date ... https://en.wikipedia.org/wiki/Waiting_for_Godot

Cette demande aurait dû être traité depuis longtemps.

When is it going to be released?

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.

Since 29 mars 2018...

No cool ! : /

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
