What data can app get from you that you don’t specifically allow? The Uber app only knows my location while I’m using it. If I choose not to give it my credit card number, I can just pay using Apple Pay and they have a one time use credit card. Not to mention with Uber/Lyft, I know exactly where my driver is, I don’t have to flag down a taxi, I know the price before I sit in the car, etc.
