Digital privacy has become one of the prime concerns in today's technologically advanced world. Security breaches have become more common now than ever and this is exactly why there is a need for encrypted messaging apps to secure your privacy. Over the past few years, the awareness about malicious activities like data theft and online snooping and the need for online privacy has significantly increased.

Although there have been major efforts by the government and tech agencies to balance public security and data privacy, the encrypted messaging tools can surely be very helpful. Since users have become more concerned about their privacy online, app makers have been seen to make continuous efforts towards adding end-to-end encryption to the messaging services. This article will highlight major concerns when it comes to online data privacy and will also talk about the best messaging apps for privacy. Moreover, there is a method for you to enhance your privacy security.

1. Why Individual Data Privacy Is Important?

In plenty of jurisdictions, data privacy is considered very important and in order to protect this there are certain data protection laws in place as well. Data privacy is also very important to every individual as they need to trust that their personal data gets handled with care whenever they engage online. Personal data can be misused in a number of ways online if its privacy is not maintained or if the individuals have no control over how their personal data is being used. Below are some of the ways in which your personal data can be misused.

  • Criminals can harass or defraud you using your personal data.
  • Without your consent, certain online entities can sell your data to outside parties who can then keep sending you annoying advertisements for marketing.
  • You can feel restricted mentally to express how you feel even with your friends when you have a feeling that your personal conversation is being monitored and tracked.

Due to the above reasons, individual data privacy is very important. When these outcomes are faced by a business, it can affect their reputation and lead to sanctions, fines, and other consequences legally.

2. What Is Secure Messaging?

Plenty of elements are involved in secure messaging. We have chosen the most important elements that qualify a messaging app to be secure. Multi-mode messaging, end-to-end encryption, and syncing capability among multiple platforms are the key elements that decide whether a messaging app is secure or not.

encrypted messaging

Multi-mode messaging

This feature allows the individuals to exchange messages via videos, texts, or audios. When an app allows the users to send their messages using different modes, any kind of message that they send or recieve can be deleted by the user.

End-to-end encryption

Through this feature, all the messages exchanged are secured by encrypting it. This would allow only the user to read the message and nobody else. When this feature works fine, the app developer, internet provider, as well as any government agency cannot read any part of the messages exchanged. This is why this feature is considered to make any messaging app secure, safe, and private. If you come across any app that does not support end-to-end encryption, it cannot be deemed secure. When the message is sent, it can be decrypted using only a secret stored code and this can be done only by the sender and receiver. Encryption ensures that no copies of the messages are saved elsewhere.

Multi-platform support

This feature ensures the synchronization of messages across multiple platforms including web, mobile, and desktop. If you ever feel more secure storing the messages in only one location and deleting it from the others, it can further increase your data privacy.

3. How to Choose a Private Messaging App?

Although there are plenty of private messaging apps available online, not all of them are as secure and private as they claim to be. All the best private messaging apps mentioned in this article offer the feature of end-to-end encryption. This means that nobody else apart from you can read or see the messages you exchange unless they have the secret code or private key for decrypting your message. This means that even your service provider cannot view the exchanged messages. Even hackers, government officials, as well as abusive employees cannot read your messages, unless you show it to them. However, each of these apps have their own advantages and shortcomings. You will know more about this in detail as you read on.

4. Best Privacy Focused Messaging Apps

Here are the 19 best privacy focused messaging apps that can be used by you for safe and secure message exchange.

4.1 WhatsApp

whatsapp app

Compatibility: Android, iOS, Windows, MacOS, KaiOS.

Price: Free

More than 1 billion users use WhatsApp on an everyday basis to communicate with their loved ones and friends. It has a very user-friendly interface and offers excellent features like file and location sharing, gifs, and so much more. It also has a desktop version for those who would like to use it on their Windows PC or Macbooks.

It uses the Signal by Open Whisper Systems protocol for powerful Perfect Forward Secrecy encryption. This means that, even if someone manages to steal the secret key to your conversations, they would be able to see only the last message sent by you and everything else will remain secure and private. Although this is a great secure messaging app, a few people still find it hard to trust WhatsApp since it underwent a major security breach in 2019.


  • Uses encryption by signal.
  • Used by almost everyone.
  • User-friendly interface.

4.2 Facebook Messenger

facebook messenger

Compatibility: Android, iOS, Windows, and MacOS.

Price: Free

Although billions of people use Facebook Messenger, not many are aware of this fact that this app uses end-to-end encryption. However, this should not be your first choice when it comes to picking the best messaging app for privacy, since this app still collects data like whom you text and how often you are texting them.

Also, in the year 2018, Facebook Messenger faced a major security breach which makes many people still doubt the security maintained on this app. Private conversations getting leaked can be a major turn down for any app and makes users apprehensive about trusting their service again.

  • Does not use encryption as a default setting.
  • The past conversations are not encrypted.

Price: Free

When it comes to cybersecurity, Apple services have always been on top of the list. iMessage is an alternative to the SMS app that has been inbuilt on all iPhones. iMessage features end-to-end encryption which keeps all your conversation safe and secure. However, even iMessage has its own set of vulnerabilities which makes it fall short of being the best chat app for privacy out there.

Data like contact lists, IP addresses, timestamps and mobile numbers are stored in the form of plain text instead of hashes. Any of your phone data that gets synced to the cloud storage called iCloud and any metadata is not encrypted by iMessage.


  • Encryption is always turned on by default.
  • No matter which device you use this on your messages cannot be accessed without the passcode.
  • Video calls made via iMessage are E2EE.


  • Collects the information of users based on their behaviour.
  • Data encryption fails when it comes to metadata, mobile numbers, and data stored on the cloud.

4.4 Viber

viber app

Compatibility: Windows, HarmonyOS, MacOS, Android, and iOS.

Price: Free

Viber has a user base of more than 260 million users and was primarily introduced as a competitor for Skype. It was initially launched for Android users, and was later developed for Blackberry and Windows devices. Since 2016, it has enabled end-to-end encryption on all the conversations made via this app making it one of the most secure messaging apps.

The most unique feature supported by Viber is that it color codes all your conversations based on how secure they are. For instance, if your conversation is highlighted in grey, it means that it is encrypted. The green color denotes that the communication with a trusted contact is encrypted. The red color signifies that there is a problem with the authentication key.


  • Features end-to-end encryption on all platforms.
  • Color codes your conversations based on how safe and secure they are.
  • Supports the feature of self-destruction.

If you wish to use this security add on, you will have to enable the "Secret-Chat" feature on this app. This feature has been inspired by the security features offered by the popular app, Telegram.

With the help of this feature, users can opt to secure their chats with end-to-end encryption. However, the default mode which is set on KakaoTalk app is not end-to-end encrypted. So, if you wish to chat securely on KakaoTalk, you will have to enable it.

Due to its advanced security features, over 100 million people can be seen using Telegram all over the world.

However, the data privacy is not all that good as Telegram claims it to be. It is very strange that an app which claims to be high on data security does not have end-to-end data encryption turned on by default. Most of the people who use this app are not even aware of this fact which beats the entire purpose of this app being categorised as a secure messaging app.


  • Has the feature of disappearing messages.
  • Very easy to use interface.


  • Not an open-source app.
  • Encryption protocol used is proprietary.
  • The encryption feature is not enabled by default.

Once you use this app you will realise that there is no unwanted appearance of ads through which agencies generally collect user data.
