How cookies are used by the Met Office
When we provide services, we want to make them easy, useful and reliable. Where services are delivered on the Internet, this sometimes involves placing small amounts of information on your device, for example, computer or mobile phone. These include small files known as 'cookies' or 'local storage'. They cannot be used to identify you personally.
These pieces of information are used to improve services for you through, for example:
- enabling a service to recognise your device so you don't have to give the same information several times during one task
- recognising that you may already have given a username and password so you don't need to do it for every web page requested
- measuring how many people are using services, so they can be made easier to use and there's enough capacity to ensure they are fast
You can manage these small files and learn more about them from the article, Internet browser cookies - what they are and how to manage them. Please note, where a browser allows, local storage may be used in preference to cookies.
If you'd like to learn how to remove cookies set on your device, visit aboutCookies.org.

Measuring website usage (Webtrends Analytics and Google Analytics)
The Met Office uses Webtrends Analytics and Google Analytics to understand how people are using the website and identify areas that can be improved or removed. The Webtrends and Google Analytics cookies are not used to identify individual users, but to produce anonymised statistics on how the site is used. These cookies therefore allows us to recognise and count the number of visitors and to see how visitors move around the site when they're using it. This helps us to improve the way our website works, for example by making sure users are finding what they need easily.
