I suggest a Proton contact app, with synchronization with the Proton account, and with the possibility of having the contacts appear in the default contact app on the Android smartphone.

All encrypted, of course.

That's the only reason I haven't switched to Proton yet. Once contacts can be synchronized with the phone's address book, there's nothing to stop me from switching COMPLETELY to Proton.

I have a paid Visionary account along with my wife. We are both retired from successful business and have a lot of shared contacts. We have blown out Google everything and moved to ProtonMail, Shared Proton Calendar, and Shared Proton Pass on our family's accounts and passwords. All we are lacking is to have shared Contacts. That would complete the sweep for Proton. Please allow us to share contacts!

This is the one thing Proton should consider before adding other apps. I feel it should be at the core of it all. I want to have my contacts in one place, syncing with my emails, a new Proton chat app, my calendar, etc.

The Proton Mail contact book is one of the oldest components of the Proton user experience. And it feels like it as a user. Data entry between Web and Mobile is not consistent. There is no client-side personalization when browsing contacts based on information in the contact. Data like contact birthdays does not appear in Proton Calendar. Data entry is a hassle, and data entry experience on mobile is not great. The Proton contact book is also exclusive to Proton Mail, which means any Proton user who has a mobile phone is likely either maintaining two contact books, or chooses to only use one and ignore the other.

It is time. Proton Contacts needs to become the next cornerstone app in the Proton product family. Instead of being an oddly-integrated part of the Proton Mail experience, graduate the contact book from its humble beginnings into a true competitor that rivals contact solutions from Office 365 and Google Workspace.

For Business users specifically, Proton Contacts is the missing enabler that would give the Proton product suite the ability to compete at a foundational level with Office 365 or Google Workspace. For Proton Business customers, an address book can be one of the most important parts of an organization. Imagine how useful it would be to provide an organization-wide contact book maintained by admins, while allowing each user under my plan to maintain their own contact book as well.

The improvements and maintenance to existing apps plus the advancement of new and exciting apps from Proton is great. The Proton product family is very strong, and great UI/UX makes complex security details seamless and invisible for people who don't care how GPG encryption works. But the Proton Mail contact book is one sore spot in the Proton product family that needs love and attention. It is awkward at best. This would be a nice complement to the highly-upvoted idea for a Proton Contacts mobile app.

Proton Contacts is the missing enabler that would give the Proton product suite the ability to truly compete with Office 365 or Google Workspace. Proper mobile support for Proton Contacts separate from the Proton Mail app is the next right step to make the Proton product family a real competitor for any privacy-conscious user or business/organization.

Agreeing with the below comments. How can we get completely away from Google without a Proton contacts app?

It's the only item preventing me moving totally off gmail.

HOW IS THIS NOT A THING YET!?!?

this has been here since 2022 and rudimentary version of it is already integrated into Proton Mail. What's the hold up?

This is about the easiest thing to do...
If storage is an issue, use proton drive to store the info.
If it's the UI, you've already got one in Proton Mail, just move it to it's own page.
If it's the app, use an open source app as the base

I want to move completely away from "Big Tech" but not having contacts sync or regularly backed up is a REALLY tough sell for many people who want to simply move without hassle

I would also like a dedicated app

I would like to have an dedicated Proton app for Contacts on iOS!

Agreed, how can I degoogle if I can't export my emails, calendars AND CONTACTS to seperate apps. My contacts are shared between emails/calendar life on PC/smartphone and phone app on my smartphone like in Google/iOS. Any nex contact that goes into my phone needs to sync with email/calendar contacts and vice-versa like in Google.

This is desperately needed. I love the Proton ecosystem and its rich features. I can't understand why such a basic app is missing. It's super annoying to always open the mail app and in the menu scroll down to the contact button, just to open my contacts. At the end of the day, contact data is top-priority data and it would definitely deserve its own dedicated app.
All that has to be done is to provide an icon that opens up the same contact dialog as the email app. So it could also be a simple widget that is part of the mail app that opens up the dialog.
Please, please, please :-)

you guys announced in your blog this is coming at the end of last year should probably change it to planned

I would like to be able to see my contacts with a single-click, just like I can open the Proton email or Calendar individually in the Windows 10 interface. In addition I would like a similar app on my Android phone which would allow me to directly open my contacts (perhaps with a 4-digit pin for security).

This is absolutely needed ASAP. This is the one thing that is left to create a true replacement ecosystem for the big names. It is so frustrating that I can't have all my contacts saved and have them synced between my phone and my email

Protonmail and calendar are not secure until this is done, because the awkward contacts widget in protonmail still forces me to share my contact list with google. I want to disable my google contacts and be free from google both desktop and mobile. This is the last piece of the proton ecosystem - please make it a priority.

Yes I would very much like an address/phone book app where I can keep various bits of information about my contacts in a secure manner. Stuff like contact details, birthdays, addresses, and misc notes like clothing sizes or food preferences

I'm not a very technical person, so most of the suggestions are somewhat cryptic to me. I wanted to suggest a contacts backup because I don't want to rely on creepy google to store all of my contacts, but if I don't rely on it, the loss of my phone would be pretty devastating. Basically, anything that google or microsoft handles, I would prefer that Proton handles in the most ethical way.

This would be amazing as it is one of the last features missing to move 100% of my items off apple world.

Indeed contact management needs improvement: should work seamlessly with your mobile standard contact apps (like on IOS) or replace it in total with a Proton contact app.
Off course it needs interaction with whatsapp etc.
Another think I would prefer a function to categorize my contacts: like Business or Sport or Friends/Family etc. Labels like in Mail would do the trick.
Thx keep up the good work.
