Collaborated with Facebook, WhatsApp already had many security and privacy issues and it’s likely enough for many users to drawback using WhatsApp. Many users avoided Facebook as it was rumored that the messaging tool would not share any personal data collected. Now, when WhatsApp mentioned in a clear perspective that their data would be shared with Facebook, it’s up to you, if you swung around WhatsApp or choose or drop the idea and switch to another app.

A telegram is a cross-platform tool available for Android, Windows, Mac, iOS, and Linux. The platform uses the MTProto encryption protocol, but it doesn’t work in the same way. There is a bulk of messages stored on cloud servers and encrypted on servers. Telegram’s additional layer in secret chats offers client-to-client encryption that any other device recovers cant beyond the sender and receiver. Simply, if you send a message through a secret chat, it is encrypted, and the receiver can decrypt it. 

> In response to WhatsApp’s new privacy policy, 25 million new users joined Telegram within 72 hours alone.

Telegram is criticized for its lack of transparency no matter how much they assure encryption protocol. The end-to-end encryption is not enabled by default, you need to opt for a secret mode to be sure nothing goes off the way, and no one else taps into your communication. Beyond these caveats, Telegram is impressive in most features like chat backups and disappearing messages. 

Telegram is not secure as the brand’s marketing campaign or policy; mentions that might lead you to believe. As per interviews with leading encryption and [security experts](https://thecompetenza.com/cybersecurity-through-offshore-software-developers/), the app doesn’t meet its proclamations regarding safe and secure messaging features. Telegram does not use end-to-end encryption as it is advocated for. 

Telegram copies your address book to the server and does not thoroughly encrypt all metadata. Telegram supports up to 200,000 group messaging, which is hard to imagine in the scenario. There are a lot of public and private channels and an unlimited number of subscribers. With lots of advantages and flaws, the app is still opted for by most users. 

If ads are your concern, then Telegram is a good choice as it does not make money through advertising as noted in the FAQ. Pavel Durov supplied Telegram with a substantial donation that they don’t need supportive funds for the time being. 

**Signal**

The Signal is considered the most secure messaging, voice, and video conferencing platform with end-to-end encryption. Signal USP is highly focused on privacy. Its source code is peer-reviewed, and independent experts frequently inspect security and privacy. The biggest strength of the platform is its privacy: it encrypts calls, texts, gifs, group calls, and everything. However, the flaw it carries is its backup and restore mechanism is not up to mark. In case you switch phones, you need to follow convoluted steps to transfer your chats to new devices.

> Between 6 Jan to 10 Jan, 2.3 million people downloaded Signal app in India.

The Signal is the most secure messaging app considered right now. Beyond Elon Musk, Edward Snowden also recommended Signal due to its end-to-end inception, which makes it extremely difficult to spy on conversations.

**Final Verdict**

The WhatsApp privacy issue has been popping up everywhere, declaring its intention to use your data for advertising. It has been a major concern for users.
