See Chicago-Kent College of Law Professor Lori Andrews on NBC Chicago tonight at 10 p.m. (Thursday, November 2) for a special report on the study she undertook with students on what fitness and health apps actually do with your private information. She found that 77% of diabetes apps and 69% of bipolar disorder apps share app users’ information with data analytics and marketing companies—and this can cause users to be denied credit or life insurance.
