Use of cookies by AHDB

AHDB websites use ‘cookies’

What are cookies?

Cookies are small files that are downloaded to your computer or mobile device when you visit our website or application to help us make our websites, and your user experience, better. Cookies mean that our website will remember you.

Cookies come in two categories Session and Persistent.

Session cookies: Session cookies last as long as your online session and disappear when you close your browser.

Persistent cookies: Persistent cookies have a fixed expiry date that means they stay on your device between online sessions even if you close your browser. This can be useful in situations where a website or web application needs to remember preferences from your last visit. 

What do we use them for?

The Cookies that we use have variety of uses that fall into the following categories

Essential Cookies: These enable essential services of a website or application to function such as security and authentication services.

Functional Cookies: These help us provide an enhanced user experience to you by remembering certain preferences between visits to the website or application. For example, remembering if you visited the website before so that messages for new visitors are not displayed to you.

Performance Cookies: These help us understand how people are using the website or application, so we can make it better. We sometimes get other companies to analyse how people are using the website. These companies might set their own performance cookies. Some examples of how we use these cookies are:

  • Collecting information on which web pages visitors go to most often so we can improve our online services.
  • Making sure that a website or application is working properly and fixing any errors.
  • Testing designs to help improve the look and feel of the website.

Third Party cookies: These cookies are set by someone other than the owner of the website you’re visiting. Some web pages may also contain content from other sites like YouTube or Twitter, which may set their own cookies. Also, if you share a link to a website, the service you share it on (for example, Facebook) may set a cookie on your browser. We have no control over third-party cookies - you can turn them off, but not through us.
