Changes to This Privacy Policy

To the extent permitted by applicable law, we reserve the right to change this Privacy Policy from time to time. If we make material changes, we will notify you by revising the “Last Updated and Effective” date and, in some cases, we may provide you with additional notice (such as by adding a statement to our homepage or by sending you a notification using contact information you have provided). Your continued use of our Sites and Services or continued interaction with us after the effective date of the revised Privacy Policy (or such other act as specified in the revised Privacy Policy) will, to the fullest extent permitted by applicable law, constitute your consent to those changes. However, we will provide notice and obtain your consent (opt-in or opt-out) if required by law.  We encourage you to review this Privacy Policy whenever you access the Sites and Services to stay informed about our personal information handling practices, your rights regarding your personal information, and the ways you can help protect your privacy. 

General Audience

The Site is for general audiences and is not intended for use by anyone younger than the age of 18.  We do not knowingly collect personal information from individuals younger than age 18.

Collection of Information

We collect information from you when you interact with us through our Sites or Services, such as your name and contact information. Some of this information may be considered personal information under various applicable laws. We consider information that identifies you as a specific individual (such as your name, phone number, and email address) to be personal information and we treat additional information, such as IP addresses and cookie identifiers, as personal information where required by applicable law. You may also provide demographic information (your age or gender) and information about your interests and preferences. If we combine other information with personal information, we will treat it as personal information under this Privacy Policy. In addition, some services on the Site allow you to pay online, and therefore require that you supply us with information associated with your credit card, banking account, or other accepted form of payment. 

Note that we may de-identify personal information we have collected about you. For example, we may use a mathematical process (commonly known as a hash function) to convert information into a code. The code does not identify you directly, but it may be used to connect your activity and interests.

Opt-Out of The Sale of Personal Information
