Sync contacts with phone address book
Sync the Protonmail contacts with the phone address book (contacts app) and vice versa.
The one remaining hurdle for me is syncing Contacts for use on the ProtonMail webapp, which EteSync doesn't help with.
My phone contacts are stored in a DAVx5 address book synced to a self-hosted Nextcloud instance. I can easily send an email from the phone app to any of my phone contacts. But if I shift across to the web ProtonMail, I no longer have my contact details available to me - only the ones I have added/imported manually.
One solution would be for the mobile app, which is already authenticated against the ProtonMail servers, to sync contacts that are optionally in a specified group (eg, "ProtonMail") between my ProtonMail Contacts and my phone contacts.
Another could be to add functionality to Bridge - as well as being an IMAP/SMTP bridge, it could also act as a Card/Cal DAV bridge - which, when the Proton Calendar arrives, would help to sync back to local calendar clients.
Having commented on this in the past, I now believe that this would be a waste of Proton's resources.
This can already be achieved with the excellent EteSync, for both calendar, contacts and tasks.
I'd much rather see integration of ProtonMail contacts with EteSync. Why reinvent the wheel when a perfectly good and open source solution already exists?

This feature would definitely help to get rid of Gmail & Google Contacts all together on my Android device.

Also it would be nice to separate your contacts here on protonmail with groups, then when exporting only the ones you want instead of exporting individually or all of them
It would be Great to have Proton to Have Contacts, Calender & Texts Messaging (texting app that you can also download to windows pc)
* These Features would be Great!
* The Very Odd Thing of Proton Mail is Downloading it from Google Play who Harvest All Data! It is Odd For Security!
Also, Seeing Facebook & Google on Protonmail Pages!
The comments all seem to concur: provide us the reliable features that Gmail provides, and you'll see a flood of new and upgraded accounts with ProtonMail. As far as I'm concerned, the sooner the better.
Please! I want to dump Google (gmail)!!!
Until this feature is implement you may want to look at EteSync, a vendor neutral encrypted sync solution for contacts, calendar and tasks. While it doesn't solve the syncing of contacts between your phone and the ProtonMail address book, it does make it possible to ditch Google entirely while making your phone contacts available to the ProtonMail app.
This would also be a needed for me to remain a customer. I'd be happy to ditch google completely if this were available.
The possibility to use the protonmail contact database on iphone and therefore to be able to simply make calls will be a sine qua non condition for me to remain a customer
I really want to be able to use my ProtonMail contacts as the canonical source. Many solutions here would be acceptable, such as a bidirectional (or unidirectional PM->Contacts.app) sync, or some (I know nothing about this) contacts API (which I don't know if exists).
I do NOT want to sync any contacts and also be able to choose to block certain contacts and emails...that would be AWESOME!!
I would already be happy with just syncing names and phone numbers with my local address book. Data minimalism!
I understand why ProtonMail Devs are not for this and it is because they want to ensure our data is encrypted and secure weather its on their servers, in transit, and on our devices. Now if they allowed this features our contacts will not be encrypted on our phone making them vulnerable to other apps reading our contacts and if some customer used this feature and third party app got some contact info from their device which was also sycned with their protonmail account they may blame protonmail for failing to secure their contacts.
I think this feature still can be added it will be disabled by default and when enabled a warning message can appear warning the users that their contacts will sync to the phone address book but not be encrypted.
And for most people without this feature it kinda makes contacts useless. If I cannot sync my contacts to my phone so I know who is calling then I better stick with Etesync.
Extremely important to be able to use the PM contact manager phone-wide or else sync it.
Please find a way to sync contacts with mobile devices. As said, this will break the Google link completely.
