We value your privacy as well as our own and will not share your information with others. In fact, there is really very little reason for us to collect any of your information to begin with.
There are other interested parties any time you are online and anytime you visit any website. There are browsers, the vehicles we use to get online to begin with. There are search engines like Yahoo, Bing, and Google who supply indexes of websites and search them at our request. There are advertisers who want to know more about you and your buying habits, and all of these collect small bits of information about your online activities.
You can go to each of these entities and request removal from such activities if you desire to do so.
As for online security: It is no more or less secure than your trip to the mailbox or using your credit card or checkbook at the grocery store.
