The instant messaging app can now share phone numbers and transaction data with Facebook. The aim is to also promote safety.
WhatsApp currently shares certain categories of information with Facebook, like account registration information (such as phone number), transaction data and service-related information. It also shares information on how users interact with others (including businesses) when using its services, mobile device information, IP address.
Regarding location information, WhatsApp collects and uses precise location information from users’ devices with their permission. Even if users do not use location-related features, it uses IP addresses and other information like phone number area codes to estimate their general location.
