    • Third-party Cookies are Cookies that are set by a domain other than that of the site being visited by the user. For example, when a user visits a site and a cookie set on that site by a third-party fires, it transfers information to the user's web browser, where it might be stored or sent back with the next request to the same server. Cookies that are sent through these third-party components are called third-party cookies and are mainly used for advertising and tracking across the web.
    • Persistent Cookies are Cookies that remain on a user’s device for the period of time specified in the cookie. They are activated each time that the user visits the site that created that particular cookie.
    • Session Cookies are Cookies that allow website operators to link the actions of a user during a browser session. A browser session starts when a user opens the browser window and finishes when they close the browser window. Session Cookies are created temporarily. Once you close the browser, all session Cookies are deleted.
    • Google Analytics Cookies. Our Site uses Google Analytics Cookies, which monitor traffic levels, search queries and visits to our Site. These Cookies enable Google to determine whether you are a return visitor to the Site and to track the pages that you visit during your session. For more information about Google Analytics Cookies, please see Google's privacy policy.
