If you use a credit card your every purchase, location, time, balance, etc. is known or can be retrieved. It just is not worth it to worry about it. 50 yrs ago the bank could, if they wanted, see every check you wrote, to whom and if you filled it out the reason. Unless you pay cash without a receipt. Doesn't anyone remember how the JC whitney, and sweepstakes people would be sending you mail before anyone else when you moved. Your name address and phone number use to be listed in a book free to everyone. Now on the internet I have to pay to see my own phone number.
