I just started my de-googling journey recently, and so the mechanics of notifications were still unclear to me, and I found this video super helpful.

It explains how most mobile messaging apps (including privacy-focused ones like Signal) rely on Google and Apple's centralized servers to deliver push notifications, which exposes vast amounts of user metadata.

Here's the YT link, for people who prefer it: https://youtu.be/c3ennD3wKn0

This is the reason why I went out of my way to use Molly (a fork of Signal), since it supports delivering the push notifications through a self-hosted server instead. Unfortunately the process is complex: it requires both a method to deliver the notifications to your phone via UnifiedPush (an alternative to Google's push system that generally suffices on its own) and a compatibility service called MollySocket (that bridges Signal's notifications with the UnifiedPush provider). Both typically need a self-hosted server and specific configuration to talk to each other though. And I don't even have any contacts that use Signal anymore, so, well...!

You can use push providers if you trust them. For example mozilla hosts one.

The MollySocket service also does not need and does not have decryption keys, only keys to request encrypted messages from signal servers. Still not something I would want to run on someone elses server without serious privacy considerations.

Yup, that's why I use my own server to host both MollySocket and UnifiedPush (via NTFY).

NTFY can provide UnifiedPush? I didn't know that!

Yes, you only need to ensure your instance of ntfy allows public access to all items with the up prefix in the settings.

Oh and then set your mobile app to enable UP in the settings of course!
