I use Quickbooks online and I am having the same problem.  You used to have to manually click in save the card for future use and now it is automatically clicked and I have to remember to unclick it or it automatically saves the customers card. They don’t want it saved and neither do we. I followed the instructions for clearing out intuit cookies and data on google chrome and it didn’t change. It still auto saves every card. What can be done to stop/change this?
