Information Collection and Dissemination
Except as otherwise provided in this Privacy Statement and Policy, the following discloses our information gathering and dissemination practices for the Website.
In general, users can visit the Website anonymously without providing any personal information. There are, however, cases where users may be asked for personal information. For example, online surveys are occasionally conducted to better understand the needs and profiles of our Website users. Our online surveys typically ask users for demographic and profile information such as zip code, age, and income level. In addition, personal information is requested if you voluntarily register to receive additional information about CBOE or if you want to purchase a product directly from the Website. Our voluntary Website registration form requests user personal information such as name, mailing address and/or e-mail address. Registered Users have certain "opt-out" choices which are described in the choice/opt-out section below.
In connection with your use of forums, discussion boards, social networking or other interactive portions of the Website certain personal information such as your name and affiliation may be collected in connection with your user profile. Such personal information will be made publicly accessible and certain portions thereof may be automatically annotated to or linked to postings you make to the Website. CBOE shall have no obligation to protect the privacy or confidentiality of such profile information or any information that you post to any interactive portion of the Website.
CBOE shares information with advertisers on an aggregate basis, but users should refer to the privacy statements (accessible below) of the service providers to the Website for their policies regarding use of personal information.
