Over the past week or so we’ve seen a lot of chatter about people shifting their messaging platform from WhatsApp to Signal as a result of fallout from a change to its privacy policy. People were concerned that WhatsApp was going to start funneling data to its parent company Facebook.
There’s been subsequent clarification, but the damage has been done.
But what data do these apps have about you? That seems like a good place to start when comparing services.

And fortunately, Apple has made this easier for us by requiring that companies publish their privacy policies and come clean about what they do with your data.
So, let’s take a look at what information this gives us on WhatsApp, Signal, and Telegram. And for a bit of perspective, let’s also look at Facebook.
