Currently on an enjoyable journey of de-googling, upping privacy, data sovereignty and so on.

Apps that do this just get it.

    ok. push notifications don’t universally leak your data. apps can receive either the message contents in the push notification, which is unsafe (less so if encrypted), or a ping that there is some kind of a new notification, upon which the app can connect to the server to fetch them. Popular messaging apps probably do the former for some reason. in mattermost its configurable by the server operator but defaults to leaking data. safe messaging apps don’t do this, they just send an empty notification or such, and the app checks in for updates. signal and matrix are like that, but in both cases they wouldn’t even be able to send the message when it is encrypted.

    but back to voyager: to be able to use push notifications, the server needs to send them. Lemmy does not have the capability for that, probably not even in the 1.0 version they are working on. so the way for Voyager to fetch notifications is to check in periodically instead of using a push service.

      Doesn’t signal use ping notifications and the whole problem was with how the mobile os handles the notifications. From my understanding of the controversy the os stored information from the app when a notification is detected in a local directory (hence why it worked on signal)
