The companies says that there is not security risk to your whatsapp messages on your facebook timeline, or your status updates being sent to your whatsapp friends but they will be sharing more user data behind the scenes in order to better target advertising and suggest new contacts across the two services.
In all the examples WhatsApp gave, the businesses were doing the talking, not the listening. However, the company said there would be controls in place to allow people to opt out of business communications.
One thing that won’t change is who can read your WhatsApp messages: With newer versions of the app, they are encrypted end to end, so only the intended recipient can read them, the company said.
In its relations with regulatory authorities, Facebook and WhatsApp are damned if they do, and damned if they don’t. Facebook has been roundly criticized in the past for collecting too much information — particularly about people who don’t use its service, or are not logged in, through “Like” buttons on third-party websites.
If you want to stop your whatsapp privacy setting to show to facebook then go to your whatsapp setting and uncheck the Facebook sharing information.
