How to chat and send messages in private

It would be like sending a letter or a parcel, where the post delivery service (or customs) could look inside and see what you sent. Actually several hundred years ago in Denmark, the Kings postman was obligated to open a letter if he believed it held information that was of interest for the kingdoms wellbeing.  

Some services actively prevent you from chatting in private – when you agree to Facebook’s (and their products Messenger and What’s App) terms of service, you give Facebook permission to read and reuse any data you transmit over their service. That’d be like the postal workers taking a copy of what you sent, and using it to send you targeting advertising.

Some of the features you should look for is 

  • End-to-end encryption
  • Chat and send messages to other users or groups in private.
  • Send files securely.
  • Make secure voice and video calls or send voice or video messages 
  • Convenience features like emojis, formatting, drawing etc.
  • Supported platforms and devices
