It's for tracking you. Say you download the McDonalds app and use it a few times but one day you go to a Burger King or In and Out, they will know your location and you will get lambasted with pop up notifications saying things like "We miss you! Come in for 5 dollars off your 20 dollar order" or "It's been a long time since we saw you". They know your location at all times and then their AI simply spams you with messages and deals to tempt you not to go elsewhere and attempt to cause guilt for going to competitors. During the fake pandemic when literally everything was closed except airports (hmm... that doesnt seem like a good idea) I used the UberEats app back in 2020. I deleted it after a few months when I realized it was a waste of money and supported pajeets yet I still get emails and texts asking me "where are you? It's been so long!" It's all a big tech conspiracy to allow pajeets to keep using their e-bikes and giant cube backpacks so hundreds of thousands of them don't leave their retarded jobs and potentially leave their plan of the Great Replacement.
