Sync contacts with phone address book
Sync the Protonmail contacts with the phone address book (contacts app) and vice versa.
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.
