The use of free messengers almost completely replaced long-distance and international calls, now there is no need to pay roaming between countries and buy sim cards of those countries in which the traveler is located.
It would seem a good thing to give people the opportunity to communicate with each other for free! But what is the secret of their earnings?
How and on what do large messengers earn?
What's app - at the beginning of the program launch, the apple store could download the app for money. After offered users - from the second year of use - to pay 1 dollar a year. But after the messenger was acquired by Facebook inc, this messenger is only an appendix to the social network. What's app analyzes user correspondence, processes, and later in Facebook/Instagram users see targeted ads that seem necessary to users (target).
Viber - Popular messenger charges for the use of the main functionality. But for a fee gives an opportunity to expand the possibilities of communication between users: make paid calls (Viber Out) and express emotions with paid stickers. Viber Out service allows you to call the city numbers.
Wonderful popular apps that increase the ability to communicate between people. But now it's worth finding out:
It turns out that some popular applications make money by collecting user data and providing more accurate (targeted) advertising. In this case, it is not necessary to talk about the privacy and privacy of information about users.
It turns out that they are conditionally free! They exchange user information - to provide free communication!
So how should truly anonymous, confidential, and secure communication apps work?
-For all the energy, material costs of the technical cost of developing, launching and operating the messenger - its use can not be free!
But is your anonymity worth $10-$15 a month? I don't think so!
Not so long ago, I saw on the Internet - a similar successful project that will soon launch.
It's Stegos! The Stegos app has a simple, understandable goal - to give interested users the opportunity to communicate with each other without fear that correspondence and information will be able to fall into the hands of third parties! This feature is provided by Blockchain technology.
I will not paint in detail, if you want anonymity and confidentiality, then you here!
