1. What are cookies?

Cookies are small pieces of data stored in text files on your computer or other device. Cookies may be set by the site you are visiting or by third parties that serve content on the site. A session cookie lasts for a single visit. A persistent cookie is remembered across repeat visits. Cookies help keep your experience consistent and perform essential functions such as keeping you signed in.

Websites and emails may also contain other tracking technologies such as web beacons or pixels. These are usually small transparent images that gather information for similar purposes. They are not stored on your device the same way, so if you disable cookies a beacon may still load with limited functionality.

2. How we use cookies

Some cookies are necessary for technical reasons such as website security and optimization. Some enable a personalized experience. Some let us distinguish unique visitors so we can measure whether our content is useful.

3. Types of cookies

• Necessary

  Essential for the technical functioning of the site: security, load balancing, optimization, and preserving your state from page to page.

• Analytics

  Help us understand how visitors interact with the site: pages visited, referring sites, browser, operating system and device information. We use this to improve how the site works.

• Marketing

  Used to measure the reach of our own outreach and to show relevant information about our services. These are generally persistent.

• Third party and embedded content

  Widgets and embeds such as social sharing buttons may set their own cookies. Those cookies are governed by the privacy policies of those services.

This list is representative rather than exhaustive.
