WhatsApp processes several different types of data from the user, such as the user’s phone number, profile name, profile photo, hardware model, battery status and IP address. Generally, the categories of processed data have stayed the same between 2018 and 2021. What has been added in 2021 is the ‘Transactions And Payment Data’. In summary, when you use Facebook Pay or WhatsApp Payments, then WhatsApp will process your account and transaction information.
WhatsApp always estimates your location
The most important difference is to be found under ‘Location Information’. In the 2018 version it is stated that location data will be processed when location features are turned on. However, in the most recent version it is stated that WhatsApp also estimates the user’s location when location features are turned off on the device. How WhatsApp exactly uses this information and whether this tracking is real-time is unclear.
