It looks like we now know the number of users affected by a banned Facebook research app, which paid users $20 a month to give the social media site access to how they use their phones. The app, which in January, collected sensitive device data on about 187,000 users, according to a report.
In a letter to Sen. Richard Blumenthal, Facebook reportedly said it had collected data on 31,000 users in the US, 4,300 of whom were teenagers. The rest of the data came from users in India. TechCrunch reported on the letter Thursday.
On Tuesday, Facebook released a new research app, called. It’s available only on Android, for users 18 years or older in the US and India. Facebook says the app will analyze what apps are on your phone, how much time you spend on them, your country, and what type of device and network you’re on. Users who sign up still get paid for sharing their information and can leave anytime.
Facebook didn’t immediately respond to a request for comment.
