Cookies policy

What are cookies?

Cookies are harmless text files that web servers can store on your computer's hard drive when you visit a website. They allow the server to recognise you when you revisit.

There are two main types of cookies:

Transient (or per-session) cookies
These only exist for the duration of your site visit and are deleted on exit. They recognise you as you move between pages, for example recording the items you add to an online shopping basket. These cookies also help maintain security.
Persistent (or permanent) cookies
These stay on your machine until they expire or are deleted. Many are built with automatic deletion dates to help ensure your hard drive doesn't get overloaded. These cookies often store and re-enter your login information, so you don't need to remember membership details.

What we use cookies for:

Internet cookies are common and do not harm your system - they just store or gather site information. They help you do things online, like remembering login details so you don't have to re-enter them when revisiting a site.

Additionally, cookies can be first- or third-party cookies. First-party cookies are owned and created by the website you're viewing. Third-party cookies are owned and created by an independent company, usually a company providing a service to the owners of the website.

We use both transient and persistent cookies to:

Gather customer journey information on our public site only
Temporarily store input information in our calculators, tools, illustrations and demonstrations
Store details of your marketing, product preferences to improve our targeting and enhance your journey through our sites and partner sites
Evaluate our sites' advertising and promotional effectiveness (we own the anonymous data collected and don't share it with anyone)
Evaluate our sites' advertising and promotional effectiveness (we own the anonymous data collected and don't share it with anyone)

We don't use cookies to track people's Internet usage after leaving our sites and we don't store personal information in them that others could read and understand. We will not sell or distribute cookie information without your prior consent.
