Cannot effectively de-Google without this.

The tradeoff between having the contact information outside the proton managed high security & privacy environment vs. practical usability and adoption is really in favor of having some information in the android / iphone data world, too.

An amazing feature would be if it were configurable which fields are synced over into Android and which

e.g. treating the notes field as proton only "private notes" or having emergency contact information only in proton could be nice. Or, the street address for that matter.

Critical!
Can't wait for it.
Hurry up!

This is critical and was rather surprised it didn't exist given how advanced the rest of Proton's offerings are.

This is essential for all of us who want to securely de-Google. I'm planning on moving to GrapheneOS as soon as I can find a workaround for 1 app (Dexcom G7) but during my testing Contacts was a major hole in Proton offerings.

Agree with anyone else here, this feature is essential to create consistency within the Proton product family. Your security is as good as your weakest link. Please incorporate this, thank you!

Astonishing it's 2025, a company that bases itself with privacy and productivity ecosystem, and yet still does not have a completed Contacts App that can sync. Forcing it's users to use 3rd party non-privacy apps.
This should not be planned still. I know plenty of people who are holding out moving to Proton due to this very feature.
Ridiculous.

Promised for FIVE years now. I'm a very patient man, but that is stretching it.
Forcing users to sync contacts and calendars to other services (Google...) beats the effort of investing in data protection and privacy!

any update on timeline for implementation ?

Trying to move away from google and this is one of the obstacles preventing me from completely leaving google for proton. Would like to see this implemented.

I've been a paying Proton user for over 3 years, and am waiting semi-patiently for this feature to come out. Would be really nice to sync contacts with my smartphone and have a Contacts specific app that is more robust and allows for full contact management across platforms and devices. C'mon Proton! What's taking so long?? Thanks in advance for rolling this one out!

I don't even need synching with the native apps! I just need a real contacts app. Or put the contacts button at the top of the mail app! Let me group contacts that don't have email addresses. Let me search for contacts. Please.

Please make this an automated bidrectional sync 😀👍 Your Google Import does a great job. Now you just need to add its compliment: Google Contact Sync (automated!)

This thread is from 2017, how is this still open?!?!?

I am trying to move away from Google. The fact that the protonmail contacts are not available in the dialler makes this much more difficult.... at least with Proton.

Include functionality to select which fields to sync. I would only sync phone numbers so that I can use it with phone and messaging apps like Signal. Better yet, have a Proton Contacts that can be the default contacts app in Android.

I am a satisfied Proton user but there are things I can't understand:
the apps, at the moment, are not entirely consistent with the web app. Frankly, I don't understand why. If the solution is so far from becoming, why not delete the apps for the moment and urge users to use the web platform?
The problem of contacts that, at the moment forces you to keep two separate address books (google and proton) was presented in 2019 and, five years later, never resolved. Keeping two address books or making cumbersome imports with questionable results, does not make Proton an alternative service. Wouldn't it be a good idea to get to work by creating an effective synchronization or creating an app that allows you to use Proton contacts on smartphones too?
These are problems complained about by many and that contrast with Proton's replacement philosophy...

How long is this going to stay planned? Another 4 years?

Without that feature Proton contacts is worthless because you have to use another service to sync your contacts.

Rlly no sync or because of security reason copy out option available?!
