http://www.net-security.org/images/reviews/threema-icon.jpgIf you're concerned about the privacy of your mobile communications, there's a variety of tools you can use to protect yourself.

Today I'm taking a closer look at Threema, a mobile messaging app that comes with end-to-end encryption and supports iOS and Android, with a Windows Phone edition in the works.

How secure is Threema?

The company behind the software can't decrypt any messages since they don't have the private keys. All encrypted messages (including media) are deleted from the servers as soon as they are delivered.

While being transmitted to the server and to the recipient, the header information of the messages is protected by an additional encryption layer to prevent eavesdropping.

All Threema servers are located in Switzerland, and you can use it anonymously, without providing a phone number or email address.
