In addition, we and the third parties that provide content, functionality, or services on our website may collect information about you and/or your device(s) via cookies and similar tracking technologies, including to provide you with more relevant content and promotional materials, on and off the website, and to help us understand your interests and improve the website.

Your California Choices and Rights

California residents may request access to the specific pieces and categories of personal information that we have collected about you, the categories of sources for that information, the business or commercial purposes for collecting the information, and the categories of third parties with which the information has been shared. California residents also have the right to submit a request for deletion of your information under certain circumstances. Consistent with California law, if you choose to exercise either of these rights, we will not charge you different prices or provide different quality of services unless those differences are related to your information.

If you would like to access or delete information, or otherwise exercise your rights under the CCPA, you may contact us using the contact information provided at Any such request may be manually or electronically signed by any process that satisfies the California Uniform Electronic Transactions Act. These rights are not absolute, and we will respond in accordance with the CCPA. For example, once we receive your request, we may verify it by requesting information sufficient to confirm your identity. If you would like to use an agent registered with the California Secretary of State to exercise your rights, we may request evidence that you have provided such agent with power of attorney or that the agent otherwise has valid written authority to submit requests to exercise rights on your behalf.

Do Not Track

Some internet browsers have incorporated “Do Not Track” features.  Most of these features, when turned on, send a signal or preference to the web sites you visit indicating that you do not wish to be tracked (“DNT-signal”).  As reflected in the Policies above, we are committed to providing you with meaningful choices about the information collected on our website for third party purposes, and that is why we provide the variety of opt-out mechanisms described in our cookie panel, where deployed.  In addition, where we deploy a cookie panel, it is designed to identify a browser-initiated DNT-signal and apply it to the cookie settings per your preferences.  However, despite our best efforts, this may not function for all browsers.  Using the cookie banner settings will ensure that your preferences are appropriately reflected.  Despite the protections described above, whether we deploy a cookie panel or not in your market, we do not currently recognize or respond directly to browser-initiated DNT signals.
