Do they have such thing as "non-encrypted push notifications"?

To send a push notification to the iOS app, you need to talk to
Apple's servers using a SSL client certificate they give to the
developer. For the official app, obviously only Mattermost's servers
have that certificate. Either you proxy your notifications through
them (which apparently costs money), or you put your own app in the
store and talk to Apple directly.

If you don't do either, the app would probably still work, but you get
no notifications while the app isn't open/active.

I don't know much about Android's push notification system (GCM) but I
think it works in the exact same way.
