“Respect for privacy is coded into our DNA. Since we started WhatsApp, we’ve aspired to build our Services with a set of strong privacy principles in mind.”
The relation between Facebook and its other services has been mentioned in the policy. The content shared by WhatsApp with Facebook focuses on making personalised content and making suggestions. This exchange of information is to help provide a better experience and show relevant ads to the users.
The main changes in the policy is the information extracted from the device used such as, battery percentage, signal strength, browser information, the kind of mobile network used, language and time zone.
Some further changes in the policy is about deleting an account from the platform. If an account is deleted from the platform without using the in-app delete feature and simply uninstalling the app, then the user’s information still remains with WhatsApp.
The data shared may also be shared with the data collection centres of Facebook, as mentioned explicitly in the policy. And as for location tracking, even if Location features are turned off, it can be tracked by using the phone number codes to find out the country or city.
