Perhaps when you opened WhatsApp, you briefly saw the pop-up window. And scrolled down as usual and tapped the button «Agree». And forget the message again.
WhatsApp wants to share data with Facebook companies
The background: WhatsApp would like to make our data available to all Facebook companies. This is in contrast to previous statements. Unlike in the past, you can no longer prevent data sharing with Facebook.
Specifically, this means: If you agree to the new data protection guidelines, WhatsApp allows account details such as telephone numbers or status information to be forwarded to the Facebook companies. Therefore WhatsApp had to get our “approval”.
Alternatively, there are other messengers such as Threema, Wire, Telegram or Signal. However, most people around them still mainly use WhatsApp.
