I use them, and recommend them. Full E2EE is my number one requirement - after learning what can be done with just metadata.
Lack of 3rd party clients doesn’t bother me.
That they allow integration with your phone’s contacts app is a big win - Proton don’t allow that.
















Thank you!
I love the explanation of how software is written, read and whether we can ‘see into it’ and verify there’s no nasty stuff going on.
For that reason of course we do try to recommend FOSS whereever possible. However, we’re not totally against proprietary software, so long as the build in privacy-by-design features e.g. E2EE.
We actually want to build sofware ourselves, and are looking into how to build it open source. Any advice welcome!
