Some browsers and tools may include a “Global Privacy Control” to enable California residents to communicate their “Do Not Sell or Share My Personal Information” preferences to websites, under the CCPA.

  1. How can I change cookie settings on my mobile device?  

You can review and change permissions regarding targeted advertising by adjusting your device privacy settings. This means that you will no longer get targeted ads; however, you may still receive contextual or general ads.

Most device and smart phone operating systems (e.g., iOS, Android, Windows) will have settings on how to manage privacy preferences, including on how to prevent the delivery of tailored advertising and tracking. For example, iOS users can deny apps permission to track your activities across apps and websites on a mobile device in the device settings. You should refer to your device manufacturer’s most recent instructions on how to restrict tracking, reset advertising identifiers, and/or opt out of targeted advertising all together.   Note that choosing to reset your advertising identifier on Android phones is much like deleting cookies in a browser—the device is harder to associate with past activity, but tracking may still occur using the new advertising identifier.

  1. Do you use third-party cookies from other companies or ad networks?

We may send users targeted ads, based on their location and activities on our Site and in order to do so we may allow third parties to use cookies to collect usage information on our Sites and display targeted ads and content to you on our behalf; these third parties may be able to associate the information they collect on our Sites with other information they have about you from other sources. (Please see our cookie list below, for a list of third parties.)  This enables us and these third parties to target advertisements by displaying ads for products and services in which you might be interested and to measure and improve the effectiveness of targeted ads. These third-party cookies and other technologies are governed by each third party’s specific privacy policy, not this one. You may opt of Targeting (and other cookies) on our Sites as described above.

For more information about how third-party cookies are used for targeted advertising and how to opt out of certain third-party advertising related cookies, please go to these self-regulatory advertising industry organization websites:
