Introducing Encrypted Contacts for Android and iOS, now available through Proton Mail’s mobile app

Last update on September 12, 2023 Published on March 29, 2018

We launched encrypted contacts last year(new window) to meet the needs of journalists that needed a safer way to store sensitive information about their contacts. Our encrypted contacts manager uses zero-access encryption and digital signatures to keep your contacts data private and verify the integrity of the data.

Now, encrypted contacts is also available on our mobile apps, so you can stay protected even on the go!

In the older versions of the Proton Mail mobile app, the contacts menu only included the contact’s name and email address (these, by necessity, are not encrypted to allow us to get your emails to their destination). If you tapped on a contact, it would simply open the email composer.

With the latest update, we have incorporated a fully functional contacts manager into the Proton Mail mobile app. You can now add additional information such as phone numbers, addresses, URLs, and notes. All of this additional information is encrypted and no one but you can access it — not even we can access it. That’s the benefit of zero-access encryption(new window).

And just like the web version of Proton Contacts, all contacts are digitally signed(new window), meaning you’ll get a warning message if it seems an attacker may have tried to tampered with your contacts.

We’re excited to deliver the most secure mobile contacts manager, and we welcome your feedback. If you have any questions or comments for the team, don’t hesitate to get in touch(new window).
