I am as concerned about your privacy as you are. That is why this site is structured, hosted, softwared the way it is.
You may be a special user of this site. A blogger, a staff member, a customer (who wants to) have different kinds of user access. That is one way I protect your privacy. But feel assured that you can buy a product from me without my being the cause of advertising reaching your eyes tomorrow as a result of your having been to my site.
If you wish you can choose to sign up with us as a customer user. Then you AND I see your purchase history. No one else. I know, if you are as I, that you might fail to download your product before the limited time is expired. We can better help you to get another try at it if you are a “member”. But it isn’t at all necessary.
