Android apps send data to Facebook the moment a user opens the app. Facebook denied any accusation and said developers were responsible for configuring the apps to share or not share data.

The Android apps share info on the device being used, the language and time zone settings, they also send to Facebook other sensitive data, including a women’s period.”]
