Zangi: 10-8329-5151
Zangi is the only cross platform IM client that I use that supports end-end encryption. It is also made available for people that do not wish to provide their telephone number. While I know no one with Zangi, it is still and option for those that might have the app. While I was pretty clear that I wasn’t considering adding new IM clients, I have decided to make an exception with Zangi. If you are interested, you can contact me through the above number.
Zengi is not a very popular company. There are services such as WhatsApp, or Telegram, but I have chosen to not use those services. As mentioned, Zangi is good for situations where one does not wish to disclose their telephone number.
