Facebook knows what people are doing on their phones even if they don’t use the social network


It has been getting the data from Onavo Protect, a free VPN app that claims to help “keep you and your data safe when you go online”, which was created by a company Facebook bought in 2013.


Unfortunately most VPNs won’t help you if you’re using an app that is collecting your data. WhatsApp can be end-to-end encrypted, however they still know the metadata of all of your messages, so they know who you are talking to, how often, and when.
