About web cookies

Web cookies are small snippets of text saved in a browser that can store data and anonymously identify your computer or mobile device. Like most websites, WWF uses cookies.

We use cookies for five main purposes:

To let you do things on our website - for example, if you make a donation or use our footprint calculator, cookies remember where you are in the process from page to page.

To improve your experience of our website - for example, so you only get asked to take a survey once, or to hide a form if you’ve already seen it.

Collect anonymous statistics - it’s really useful for us to be able to see which pages are the most popular and how people are using them.

Social media - if you use Twitter or Facebook, cookies can help smooth the sharing process between our site and your online feeds.

Measuring how cost-effective our advertising is - as a charity, we need to watch our advertising spend carefully. Cookies are used to help us see how many people who click our adverts go on to do something further (for example, donating, adopting an animal, or becoming a member). These cookies expire after 30 days of inactivity and do not contain information that can personally identify you.

Turning cookies off

All modern browsers let you turn off either all or third-party cookies, but this varies depending on which browser you're using. The option to do this is usually found in your browser’s Options, Settings, or Preferences menu.
