A new social media app is offering itself to you for free. If you upload a picture to it, the app will show how you will look at 10 years. John Doe, a friend of yours, says not to use the app as it will then possess your biometric facial data. Jane Doe, another friend of yours, says that she heard the app shares the facial data with a security firm that helps the government detect terrorists at airports. Should you use this app? Why or why not? If John Doe is right, would an utilitarian say it is right to use the app? Why or why not?  If Jane Doe is right, would a social contract theorists say it is right to use the app? Consider the role the Fourth Amendment at play here.
