What personal details of users are instant messaging apps collecting?

The new privacy policy of WhatsApp has troubled people. But how much data does it collect compared to other messaging apps like Signal, Telegram and Facebook Messenger? If you are also thinking the same, then let us tell you that the new policy shows that WhatsApp collects a lot of your data. Apps owned by Facebook (Messenger and WhatsApp) collect your data and location information unlike other apps. Whereas, compared to these, Signal feels like the most private and secure messaging app and as per the privacy details highlighted on the App Store, this app does not collect any user data. Perhaps this could be the reason why Facebook had criticized Apple’s move to show the privacy label some time ago.

Information available on the App Store suggests that when it comes to collecting user data, Facebook Messenger collects the most data after WhatsApp. User data collected by both the apps includes users’ purchase history, financial information, location information, contacts, phone numbers, email IDs and usage data, etc. Let us tell you that WhatsApp is currently being used by more than 40 crore people in India.
