Tinder and Spotify are two popular apps that rely on AI algorithms to recommend matches and music based on their users’ preferences, but exactly how do these algorithms work and how are they using our data in the process?

They also found possible legal and ethical issues within the privacy policies. Joe spoke to co-author of the study, Fabio Morreale from the School of Music at the University of Auckland, on the matter.
