IT experts at Notre Dame are warning fans of Facebook quizzes about what happens to the information they enter when filling out the questions.

Notre Dame cyber experts are looking at ways to protect your information from being exposed. ABC 57 reports that they’ve discovered that some seemingly innocent Facebook personality quizzes, such as those that tell you which Hogwarts house you would be sorted into, handed your data over to Cambridge Analytica.

Professor Mike Chapple says that data was used by the political consulting firm, and the information was used to present data during the last presidential election.

Chapple says the lesson for everyone going forward is to be cautious of what you engage in on the internet, and to delete any information from your Facebook page that you wouldn’t want shared publicly.
