Remember when it was revealed in January that Facebook used to pay teens and gather mobile app usage data from them through an app? Well, the company shut that program down after a huge backlash, but the app’s sorta making a comeback. Facebook today announced a new app called Study, that will collect your data in exchange for cash.

The social network said it will use this data to “helps us learn which apps people value and how they’re used” and understand the community to improve its fleet of apps. It also likely hopes this is transparent enough to avoid getting the company in trouble. Last year, a slew of documents released by the UK parliament revealed that Facebook used its now-defunct VPN app, Onavo, to track competitors through data it collected from users.
