Silence Circle is a military grade email, text and phone encryption iPhone app.

The first rule, former Navy SEAL Mike Janke tells me, is that you have to assume the worst: “Everything you do and say — email, text, phone — is monitored on some level.”

Check out the article on Buzz Feed and the official site for Silent Circle.

“One of the coolest tricks is a feature called Burn Notice that sends self-destructing texts and pictures. The relevant picture appears on your friend’s phone — anything from a classified blueprint to something more Weineresque — and five minutes later, the picture burns up. There have been self-deleting message apps before (most notably TigerText), but without encryption, they could never guarantee that the data hadn’t been copied somewhere along the way. Silent Circle can, and thanks to the closed platform and near-total data control, they can pull off a trick that’s increasingly unthinkable in the modern day: unsending data. They can, in other words, un-ring the bell.”
