My understanding is this is partially implemented as a one-way sync from the system (ex. iOS) to the Proton Mail app. My SO and I would love to see two-way sync including the option to continue managing our contacts in the native iOS app. We'd also love the option to have a shared contacts list to reduce duplicate contacts.

Please implement this.

Is that so hard?
if that feature isn't coming I need to leave proton again.
Acording to proton Information they have it in the backlog since over 5 years?!?!?

We need this.

I would love this, it's one of those things that prevents me from deleting my Google account. Please Proton!

It is one of the key things missing from the others great and greater Proton suite.

absolutely important. i love to have photos alongside my contacts because it feels way more personal to me but everytime i switch phones (or operating systems) i loose all the pictures connected to them.

to clarify: i want to sync phone numbers not email adresses

This is a huge missing piece. Need to be able to sync contacts to my SIM card.

This needs to be done ASAP.

Please prioritize this for Android and iOS - even Tuta has full contact integration.

It would be cool if phone contacts would be saved seperately from email contacts in Proton Mail, with the ability to restore entries that have been modified or deleted by saving history of changes and a recycle bin.
In addition to that, the contact labels in Android can be turned into contact groups in Proton Mail, and birthdays can be integrated in Proton Calendar.

I also think this is critical. I need contacts in sync between phone and proton mail.

I changed from google for domains to proton.

I'll probably have to use a free gmail account to store contacts.

What about this feature? This should we focussed more ...

That’s more than essential, it’s almost vital to a smooth (minimal I’d say..) experience at iOS…
The more integrated to smartphone OS, more people are going to interest…

critical to replace google contacts. I want my contacts to be in a safe proton space, so that whenever I loose / break my phone or buy a new phone I can get all my contacts from there without depending on wicked middleman Google

This blocks from moving to proton from Google Workspace.

I cannot replace Google without this feature 😱

Planned since Jan 2019?!

At this point I would be happy with a deep link that would open a Contacts view in ProtonMail directly. Let me put an icon on my home page that lets me skip a few taps -- as a stopgap until a proper Contacts system is available.

This is critical to replace google, please update the status of this idea.

Come on... Planned for 6 years? :/

This needs to happen to replace Google fully..
