Facebook manipulated Android app permission in the name of #growthhacking

Save your face.

Internal documents show Facebook weighing the privacy risks of collecting SMS and call records — and going ahead anyway.

The emails show Facebook’s growth team looking to call log data as a way to improve Facebook’s algorithms as well as to locate new contacts through the “People You May Know” feature. Notably, the project manager recognized it as “a pretty high-risk thing to do from a PR perspective,” but that risk seems to have been overwhelmed by the potential user growth.

Initially, the feature was intended to require users to opt in, typically through an in-app pop-up dialog box. But as developers looked for ways to get users signed up, it became clear that Android’s data permissions could be manipulated to automatically enroll users if the new feature was deployed in a certain way.
