* *It depends entirely upon the Google message pushing system*. That means that Google /at least knows who Signal messages are being sent to and may be able to infer the rest via your (insecure) Android phone contact list or via timing correlation of alternating deliveries/. Remember that for an adversary metadata in aggregate is much better than having the content of messages. At any time Google could decide that it doesn't want to support Signal, or in adverse circumstances they could be leaned upon by the usual agencies or government cronies. * *It depends entirely upon the Google message pushing system*.

To give credit where it's due Signal is good, but it could be a lot better. The real solution for private chat is to run your own XMPP server, as you can with Freedombone, or to have someone within your community do that. /There is no substitute for a good decentralised solution which is within the control of your community/.

On mobile there are various options. The apps which are likely to be most secure are ones which have end-to-end encryption enabled by default and which can also be onion routed via Orbot. End-to-end encryption secures the content of the message and onion routing obscures the metadata, making it hard for a passive adversary to know who is communicating with who.
