Whatsapp Privacy Issue and Comparison with Telegram and Signal


Whatsapp recently updated its privacy policy. It was about sharing collected information with Facebook. If you are living in Europe, this situation is not valid for you. General Data Protection Regulation (GDPR) will protect your personal data. But if you are living outside of Europe, Whatsapp made it compulsory to agree to the terms. Most people believed that Facebook would be able to read our message content, but it was not the case. They just wanted to share the data listed below for improving their targeted advertising model. Since 2016 they have been sharing this content. Due to regularizations in data privacy lately, users should agree about their data sharing.


Whatsapp vs. Telegram vs. Signal

We are sharing the comparison of the three most popular messaging apps.

Whatsapp uses end to end (E2E) encryption for communication as well as Signal. Telegram uses E2E in secret chats. The normal chat feature is not E2E encrypted in Telegram.

The Signal is fully open-source. You can check how it is implemented. Telegram is not fully open-source. Whatsapp is not open-source at all.

For our daily usage, all of the apps are safe. But if you are going to talk about critical issues related to national security, we recommend that you do not use these applications. Rules of companies may vary when it comes to national security.
