WhatsApp Vs Signal, Telegram, Facebook Messenger: What Data Does Each App Collect?

WhatsApp's new privacy policy has people worried but how much data does it collect compared other messaging apps such as Signal, Telegram, and Facebook Messenger? A lot more, it turns out, as shown by the privacy labels of these messaging apps as shown on Apple's App Store.Both apps owned by Facebook (Messenger and WhatsApp) collect usage data and location details, unlike the other apps. In contrast, Signal seems to be the most private messaging app and doesn't collect any user data, as per the privacy details highlighted on the App Store. Perhaps unsurprisingly given this fact, Facebook earlier criticised Apple's move to display privacy labels.

The details available on the App Store show that Facebook Messenger is the most acquisitive when it comes to user data collection, followed by WhatsApp. The list of data both apps collect includes users' purchase history, financial information, location details, contacts, phone number, email address, and usage data, among others.

At a time when people are expressing concerns about WhatsApp's new privacy policy changes, which you have to accept or your account will be deleted, it's interesting to note all the data that the app, which has 400 million users in India alone, is collecting.

You can see these details on the App Store yourself if you have an iPhone. Here's a detailed breakdown of all the data that these apps collect.

Facebook criticised Apple's privacy labels in newspaper advertisements shortly after they started appearing on the App Store last month. WhatsApp also separately accused Apple of implementing anti-competitive policies over the recent update. The app also provided some clarification on its user data collection through an FAQ. However, the list shared online suggests the reason for criticism and accusation.

It is important to point out that the privacy labels on the App Store are based on the self-submission made by developers to Apple that is not yet manually checked. But nonetheless, companies including Facebook also provide such details in their lengthy privacy policies as well that aren't read by a large number of their users.
