WhatsApp can create detailed reports about users, including information about their activity, contacts, and settings. This is similar to a feature in Spotify, but it is used for privacy purposes. The reports do not contain the text of messages, as they are encrypted, but may include data that WhatsApp could provide, for example, to the police. To obtain the report, you need to select the option to request account data in the settings. The reports will be generated automatically every month, and it is important to download them before they are deleted.
