How Apps on Android Share Data with Facebook (2018)

Using the free and open source software tool called “mitmproxy”, an interactive HTTPS proxy, Privacy International has analyzed the data that 34 apps on Android, each with an install base from 10 to 500 million, transmit to Facebook through the Facebook SDK. Since May 25, 2018 – the day that the EU General Data Protection Regulation (GDPR) entered into force – developers have been filing bug reports on Facebook’s developer platform, raising concerns that the Facebook SDK automatically shares data before apps are able to ask users to agree or consent.
