Comparing Signal-protocol-using messengers

There’re still privacy differences when you compare messenger apps all using the Signal protocol:

In this article, I’m going to compare WhatsApp, Signal, and Allo from a privacy perspective.

While all three apps use the same secure-messaging protocol, they differ on exactly what information is encrypted, what metadata is collected, and what, precisely, is stored in the cloud — and therefore available, in theory at least, to government snoops and wily hackers.

In the end, I’m going to advocate you use Signal whenever you can — which actually may not end up being as often as you would like.
