Millions of people exchange message all over the world every day. But, how many people know what happens to a message once they send it? Is it being intercepted by any third-party users? Well, the truth is, we live in an age of internet surveillance and data logging. Agencies and organizations often want access to private communication; we have had instances of CIA hacking attempts and attempts by FBI to gain unauthorized access. Such events have raised concerns among users. To tackle such issues, there has been a rise in secure messaging apps. These apps focus on keeping your privacy intact by launching end-to-end encryption services.
End-to-end encryption is when your service provider doesn’t keep copies of the messages you send on their servers, i.e., only the people you are communicating with can access the message. Nobody in between, neither the government nor the developers can access it.
So, if confidentiality is critical for your communication, then check out this list of some best encrypted messaging apps for Android and iOS platforms. These apps are safe to download and provides utmost security to your data.
Note: This list isn’t in an order of preference; it’s a compilation of the best Android encrypted messaging apps. You’re advised to choose one as per your need.
