OF COURSE: Facebook created a tool to hide your data from apps but it never launched.

Facebook’s policies prior to 2014 were much more lax than they are today. At the time, apps could scrape data from both their users and the friends of those users, unless you had your privacy setting sufficiently locked down.

The company actually built an “Anonymous Login” tool that was specifically created so that Facebook users could log into third-party services without making all of their data available to developers.

But the once-hyped feature never launched. Facebook quietly killed the project, allegedly due to lack of interest.

Whose lack?
