This Cookie Policy applies to the cookies we use when you visit the main Loma Linda University Health website (, the main Loma Linda University website (, as well as other websites that we own or control (if they link or refer to this Cookie Policy). Collectively, we refer to these simply as the “Sites.”

This Cookie Policy provides you with more information about cookies, what types of cookies we use and how we use them. Our Sites use cookies with the intention of providing you with a user experience that best suits your needs while concurrently allowing us to improve the design and functionality of our Sites. Cookies can be adjusted or disabled, and this policy provides you with instructions to do so. Among other things, cookies help to make your visit to our Sites more relevant and personalized for you.

A cookie is a file designed to contain a small amount of user and website information stored on a user’s computer or device.

Types of Cookies

A session cookie is temporary, linking the actions of a user during any given browser session. When the browser is closed, the cookie is deleted.

A permanent cookie, also known as a persistent cookie, is stored for a specific period of time and activates each time the user visits the website that created the cookie. They are used for purposes including tracking the number of unique visitors to our Sites and information such as the number of views a page gets, how much time a user spends on a page, and other pertinent web statistics.

Some of the cookies are used exclusively by LLUH, and therefore are called “first-party cookies.” We also use third-party service providers to assist us by providing certain statistical and analytics information. These parties may set cookies known as “third-party cookies.” A “third-party cookie” is placed by a domain other than that of the website the user is visiting.
