The Options Price Reporting Authority respects your expectations of privacy.
This Policy describes the ways in which we use information provided by users of this website.

Collection and Use of Personal Information

In general, you can visit OPRA's website without telling us who you are or revealing personal information about yourself. We do collect certain personal information automatically and, if you wish to communicate with us via email, you may need to supply us with information relating to the purpose of your communication in order to enable us to provide you with a useful reply.

Automatically Collected Information

If you visit the OPRA website, our web server automatically collects and stores information with respect to: the name of the domain and host from which you access the Internet; the Internet Protocol (IP) address of the computer you are using; the browser software and operating system you are using; the date and time at which you access the OPRA website; and the address of the Internet site from which you linked directly to the site.

The OPRA website also uses "cookie" technology. A cookie is an element of data that a website sends to the browser of a user of the website. The OPRA website's use of cookies is currently limited to facilitating use of the website and measuring activity on the website, and all information collected with cookies is anonymous. OPRA does not use cookies to aggregate information with respect to use of the Internet from a particular email address.

Voluntarily Provided Information

If you communicate with us via e-mail, you may need to supply us with information relating to the purpose of your communication in order to enable us to provide you with a useful reply. In some cases we might forward an e-mail sent to us to a third party to facilitate an appropriate response.

OPRA might use information provided to us by a user of this website to further inform and educate users about U.S. listed options, or to improve the website or the information that OPRA makes publicly available. However, if we were to do so we would not identify the source of the information provided to us. You should note that e-mail is not necessarily secure from interception. The e-mail address or addresses identified in the OPRA website do not have any encryption capability.

You should consider whether information of a particularly personal or sensitive nature is appropriate to include in an e-mail.

Notwithstanding any other provision of this Privacy Policy, OPRA reserves the right to disclose user information in special cases, when we have reason to believe that disclosing this information is necessary to identify, contact or bring legal action against someone who may be causing injury to or interference with (either intentionally or unintentionally) our rights or property, other users of the OPRA website, or anyone else that could be harmed by such activities. We may disclose personal information without notice to you in response to a subpoena or when we believe in good faith that the law requires it or to respond to an emergency situation.
