I am a firm believer that there are many privacy techniques you should focus on before encrypted messaging because they will offer you much more “bang for your buck,” things like good passwords, two-factor authentication, and even encrypted email. That said, I still believe that encrypted messaging is a critical part of a well-rounded privacy and security strategy. While the vast majority of our day-to-day conversations may be benign, it can still offer a lot of insight into who we are as people – our routines, likes, and personal thoughts. This information – mundane or not – is worth protecting.
NTFY uses the same mechanic that they do for push notifications; it keeps an open socket and then just communicates across the socket. So they shouldn’t be keeping track of that, so far as I understand the AOSP codebase.
Cool, that’s what I was hoping. I’m perpetually in the “knows enough to be dangerous” category.
