WhatsApp has long prided itself on end-to-end encryption and preserving the privacy of the messages we send ourselves with our contacts. What is not talked about so much is the metadata that it does access: This “data about your data” reveals useful information for a Facebook that now has an open war with Apple.
The Cupertino company has started rolling out its privacy labels (privacy labels) in the App Store, and with them shows and “cheats” on the data collected by applications. In the case of WhatsApp, it is clear how this tool collects contacts from our mobile, commercial data when we use Facebook services or the IP that can be used to geolocate us with some precision.
