The key is whether JD will sell your personal financial information. The disclosure you described is written according to the Financial Services Modernization Act (also known as the Gramm-Leach-Bliley Act or GLB). Essentially, JD is telling you that it reserves the right to retain records on you and your account. There are other legal requirements of financial institutions if they intend to "sell" your information. In fact, they must offer you a chance to "opt out" of any such practice and you cannot be required to allow the sale of your info as part of an agreement after the fact. If your Agreement does not discuss the sale of your information, then the intent is to simply share your information "internally" with existing JD affiliates, which likely means the marketing folks and the various divisions within the company. If those "affiliates" are not identified in the Agreement, just ask.
You should have available to you a formal Privacy Notice from JD credit. In fact, the law stipulates that you must be provided that document and that you will receive a copy each year, usually after July 1. Watch these notices carefully. Most of us just trash those little folders--I used to because I need a magnifying glass to read them. Make sure you watch for an "opt-out" procedures and deadlines. If you neglect those you are automatically giving the lender consent to a change in policy, and probably will begin to see more telemarketing, direct mail, and inquiries on you credit report.
This is just my opinion, but you are probably looking at a pretty standard paragraph. As was mentioned above, your information is most likely being shared by your bank with its partners, by your insurance company with its divisions, and even from your gas card with Mobil, Texaco, whoever.
It would be a shame to see you let that tractor go. Especially since you are going to have the same experience with the next lender. Anybody who thinks JD is worse than the others hasn't really looked to find out. All you need to do is contact your lender or the company extending credit and request a copy of their privacy policy. Most of these practices are not knew to lenders. They are just now (in 2001) required to tell you about it. The only "entities" that are exempt from many of these laws are state and federal agencies. /forums/images/graemlins/shocked.gif
