Earlier this week, it was reported that Threema was planning to launch a Windows Phone version of their secure messaging application, and right on schedule, the Windows Phone app is now available for download.
you can be certain that only you and the intended recipient can read your messages
Threema is a mobile messaging app that puts security and privacy first. With true end-to-end encryption, you can be certain that only you and the intended recipient can read your messages. You can use Threema completely anonymously, without giving away personal information such as phone numbers or email addresses. Your messages will be deleted from our servers immediately after being delivered. With Threema, you’re protected against data abuse.
It’s a WhatsApp Messenger competitor and while WhatsApp is encrypting its own messages, there’s something to be said of an application that’s built from the ground up to provide you with the privacy and security you require in this day and age.
You’ll be able to acquire Threema for $0.99 in the Windows Phone Store.
