McDonald's Built a 515-Page Dossier on Me. It Says I'll Never Stop Eating There

McDonald's Built a 515-Page Dossier on Me. It Says I'll Never Stop Eating There I requested a copy of my data from McDonald's loyalty program and received an extensive, personalized report that algorithmically predicts my next purchase. When I first downloaded the McDonald's app years ago, I signed up for its loyalty program hoping to get better deals. Why not get some cheap French fries? While I understood that this would entail some type of data tracking, I didn't grasp how the information would be used to algorithmically predict my next purchase.
