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.
You can also just use a degoogled os which won’t be logging your notification content. But in any case you shouldn’t have notifications as notifications are exclusive with at-rest encryption (or I guess you could have at-rest encryption but just have the db constantly decrypted whenever your phone is on? Seems to defeat the point then)
Which DeGoogled OS do you know of that uses their own notification backend?
You don’t need one. Just use any degoogled ROM with UnifindPush, as almost every secure messenger support it. If not, notifications can still show up via websocket.
Presumably any degoogled OS would remove that kind of telemetry—it seems like quite an obvious oversight if they continue to send notification contents to Google’s servers? If the suggestion is that it’s through a backdoor, then that’s the responsibility of the open source community to spot the backdoor in the AOSP.
