General Considerations

DARcorporation cannot guarantee that the information you provide to us is completely safe, although we are careful to try to prevent problems. There may be technical problems beyond our control that may make it accessible to unauthorized persons. There also may be visitors to the site who gather and use information available there, such as that provided by you on our discussion boards.

If DARcorporation is acquired, our user information will be included among the assets transferred to the buyer in the sale. There also may be occasions on which DARcorporation is required to provide information by order of a court or when the law requires that user information be treated as a transferable asset, as in bankruptcy.

Internet-based commerce is dynamic and changing. We may change our privacy policy in the future in order to adjust to these changes. We recommend that you check it frequently.

If you have any questions or comments about our privacy policy or this Web site’s practices in general, e-mail the site’s Administrator.
