Digitization has forever changed the world we live in. Computers, Smartphones, Wearables and AI enabled chat bots have clouded our lives and there's no escape route, unless you have set yourself on a journey to 'Into the Wild', which I believe is not the case if you are reading this article.
What suffers in all of this is human's basic right- the Privacy, which is often ignored or compromised in this digital era. You might not realize the fact that a government agency, a group of hackers or simply an e-commerce platform might be spying on the messages or emails going out from your smartphone. Sounds scary? It is actually.
To make sure whatever text you send from your smartphone is not read by anyone else on network, you should use secure messaging platforms. Thankfully, Android and iOS have some free messaging apps that are designed to safeguard your privacy.
And to make things easy for you, we have compiled a list of 5 best free secure messaging apps that you must download if you really care about your privacy. You can thank us later.
