<prompt> Human: Unfortunately many credit card companies and for-profit banks will merrily sellshare your personal data unless you opt-out, but the more responsible ones have at least added sections to their online account portal that tell you about it and make it easy to opt-out Chase is a rare positive-ish example. Unfortunately Discover buries that information in their Privacy Statement and makes you call 1-800-225-5202 to opt-out. Theyre clearly hoping people wont read the statement and wont opt-out, which is a sad and disappointingly anti-customer approach for them to take. Aside from them, I definitely recommend checking the privacy policies for all of your financial institutions and finding out how to opt-out of data sharing if possible.  <response>: Opted out the first day I got the notice.
