How often you visit the store, where you walk in the store, how long you are at the store. Your identity doesn't need to be attached for this information to be useful; for example, the store can say things like "gee look half our customers leave three minutes after they enter the store, so we are having a hard time converting walk-ins to sales". Or perhaps "Wow it looks like 90% of our customers come back within a week, we are doing great at getting repeat visits"
