Privacy. It’s quite likely the rarest commodity available to us in today’s hyper connected world. Whatever we do, whatever we say is likely to be monitored, analyzed and filed away somewhere. 

Years of social media exposure have conditioned us to be comfortable with sharing any and all of our information. From special events to private moments and even intimate pictures, it would appear that nothing is sacred anymore. 

It is likely that all of this began when social media sites first began appearing. Since their teens, millennials have been exposed to the earliest form of social media in the form of online chat rooms like ICQ and mIRC

Later on, there was MSN, AOL Instant Messenger (AIM), Friendster, Myspace, and Facebook. On these platforms, people shared pictures, interests, hobbies, and chatted with one another. 

Then came the introduction of mobile phones - where we exchanged short messages (SMS) with one another. But SMS was awkward and janky at times plus it would take minutes to send a single low-resolution picture. 

All this would then change with the introduction of Whatsapp - a messaging app that allowed users to chat and exchange images with one another. And that was when everything changed. 

Whatsapp redefined what it meant to communicate. It was intuitive, free-to-use, and allowed us to send as many messages as we liked - as long as you had an internet connection or data plan. 

For all of its conveniences, most people failed to ask one important question: 

What would happen to all the messages that were being sent? 

All the late night conversations with your friends, scandalous texts to your significant other, or private details of your latest business plan. 

With Facebook’s acquisition of Whatsapp, it would only be a matter of time before someone realized that Whatsapp is a literal goldmine of data. And the recent 2021 privacy policy update goes to show that all of your personal information is definitely being collected and used against you. 

So what do you do for WhatsApp alternatives? 

The answer is simple really - make the switch to a messaging app that protects your privacy. In this article, we take a look at the best private messaging apps that you can use in 2021. 


When it comes to keeping your data protected, Signal is one of the best messenger apps that are available on the market.
