The Facebook Study program helps us learn which apps people value and how they're used. We gain valuable insights using data from groups of participants that we use to improve Facebook Company Products. -How It Works Participants who have been invited to the Facebook Study program install the Study app, give us permission and then use their phone as normal. All registered participants have agreed to share their apps usage data with Facebook and they are rewarded for taking part in the program. We explain how to participate during registration, before participants accept the terms of the Facebook Study program. Participants can leave the program at any time by uninstalling the Study app and notifying the vendor that they want to end their participation.
