At the same time, however, WhatsApp uses IP addresses and other data for to estimate the general location of the user.
The user can use the function of loading contacts and then regularly provide the telephone numbers in your address book. If some of these do not use WhatsApp services, their information will be managed in such a way that it is not possible to identify them (more info here).
However, WhatsApp collects various information automatically, for example on user activity, on when it is online, on interactions with other people or with commercial activities and on timetables, also in terms of frequency and duration, and on the functions used. And this is just a taste: listing all the possibilities here would be long and redundant: you can consult the related section yourself
