For Signal, they will know when and how often you receive Signal messages.

Notifications are used to "activate" the app on your device. Then it will connect to Signal servers and download the encrypted messages.

After the software on your device decrypted the message, then it has the sender details and message content.

There are settings to control how much of that information is used when creating the local notification. Because other apps might log notifications.

That's terrifying for showing how little he understands about the problem he is attempting to solve.

Humans use up to four senses at times to accomplish the task of driving.

I take it you weren't aware that Google Wave was based on XMPP.

> How do they manage to make the same messages appear on multiple devices?

For a long time, they didn't.

I don't know for sure, but I expect it involves keys that multiple devices share. Any "linked" device would be able to download the encrypted copy and decrypt the message that way. Once any device has done that, it can send a copy to any other devices using the unique keys it knows for that device.

> Signal stores all your messages and media as well, the difference is they encrypt it on their servers.

What evidence do you have to support this claim?

The last time I looked into this, messages and media were only stored encrypted on servers until they were retrieved or expired.

After that, the local device is where things are stored.

This is a good video explaining things, for anyone who doesn't know about the situation Apple created.

Why don't you ask the Matrix team why they decided to re-invent XMPP and add a stupid HTTP API?

It's both amazing and annoying that Google is perfectly able to create useful apps for iOS (despite the huge limitations the OS imposes) but Apple can't figure out how to make any Android app that isn't utter crap with fewer restrictions imposed on them.

Installing from F-Droid prevents sales like this from causing silent "upgrades" to advertising-infested versions.

Done.
