Websites can automatically place small text files, known as “cookies,” on the computers of their visitors. So long as they do not expire or get deleted, cookies identify the unique browser used by the visitor. On each subsequent visit to the website, the visitor’s browser will retrieve the cookie, allowing us to aggregate the number of return visitors. We use “cookies” to test and optimize our website design and content. We may use two types of cookies on our websites:
- Session cookies may be used to gather data for technical purposes, such as improving navigation through our website and generating statistics about how the website is used. Session cookies are temporary text files that expire when you leave our website. When cookies expire, they are automatically deleted from your computer. We do not use session cookies to collect personal information, and we do not share data collected from session cookies.
- Multi-session cookies, or persistent cookies, may be to customize our website for frequent visitors and to test variations of website design and content. Multi-session cookies are cookies that are stored over more than a single session on your computer. We do not use multi-session cookies to collect personal information, and we do not share data collected from multi-session cookies. Multi-session cookies are generally set to expire no more than two years after your last visit to our website. After that time, they are automatically deleted from your computer. We are unable to identify an individual by using such technologies.
You can take actions to block cookies by opting out. Blocking session cookies from your computer will not affect your access to the content and tools on our website unless we notify you of such. Blocking multi-session or persistent cookies may affect the personalization of the information on those sites.
