The restrictions will be introduced over several weeks for each user individually. Initially, users will not have access to the chat list, and then they will stop receiving messages and calls. The company assured that all correspondence and media files would remain protected, and third parties will not have access to them.
WhatsApp changed its terms of service earlier this year. They provide for the mandatory transfer of user data to Facebook and other targeted advertising applications. Many criticized this decision, which forced WhatsApp to explain itself and then postpone introducing the new rules until May 15. It is worth noting that the messenger has been transmitting user data to Facebook for several years. Apparently, only now was it decided to register this moment in the user agreement officially.
