As the most popular messaging app in the world, it’s quite worrisome how Whatsapp is also owned by the world’s largest information company – Facebook.
Plus, given Facebook’s questionable behavior, you should start asking yourself – is my data safe?
And even if your messages are secure, what’s stopping Facebook and other companies from collecting and selling your personal information?
So, don’t worry because I’m going to show you how to keep your messages private and away from governments and companies. You can find some other options in this Tezro article: blog.tezro.com/best-encrypted-secure-messaging-apps/
Telegram is widely regarded as the most popular alternative to Whatsapp with more than 200 million users – and with good reason.
First of all, Telegram is supported on a variety of platforms and OSs, meaning that you can use the messaging app on PCs and iOS along with Android devices.
Just like Whatsapp, Telegram uses a double tick messaging system to notify users when their messages have been sent.
In terms of privacy, Telegram utilizes end-to-end (E2E) encryption of voice calls which prevents your calls from being intercepted. Messages sent via Telegram can be set to self-destruct after a set time period.
However, instant messages sent on Telegram do not have E2E encryption enabled as a default. Instead, you’ll have to use the app’s secret chats feature – which is unfortunately device-specific.
- Available on iOS, Android, and PCs
- Cloud-based backups
- Developed on open-source software
- E2E encryption is not available for normal chats
- Server-side encryption is not open-source
If you ever needed a reason to check out Signal, then consider the fact that it’s been endorsed by whistleblower and privacy advocate Edward Snowden.
Additionally, Signal has been officially approved for use by the U.S Senate’s Sergeant at arms. For context, the U.S Sergeant at arms is a highly-trained individual responsible for the security of the U.S Senate.
In terms of utility, Signal has text, voice, and video messaging capabilities – making it a great alternative to Whatsapp.
Messages sent via Signal are E2E encrypted which guarantees privacy. Like Telegram and most other private messaging apps, Signal has an auto self-destruct setting which deletes messages after a fixed interval which further enhances security.
It’s also good to see that Signal uses open-source encryption and this allows experts to certify its security.
- Uses E2E encryption by default

- Messages can be set to self-destruct
