This article talks about a secure team communication app with zero knowledge encryption. There are lots of communication apps and platforms with End-to-End Encryption but that’s different from Zero Knowledge Encryption. In End-to-End Encryption, the encryption key is stored at the server. So, someone with server-access can access your data and decrypt it. Whereas, in Zero Knowledge Encryption, the encryption key is saved locally on the device itself. No one has access to the key expect you. This gives a piece of mind that your communication is secure.

The team communication app I’m talking about is FortKnoxster. With assured data security (thanks to Zero Knowledge Encryption), this app packs lots of features. It has text messaging, voice calling, video calling, video conferencing, file sharing, and email inbox built right in. Free users can access all these features except video conferencing along with 1 GB file sharing space.
