Cookie policy
Which cookies this site uses, why, and how to change your choices.

What cookies are
Cookies are small text files a website stores on your device. Similar technologies, such as browser storage, work the same way, and this policy covers them too. Some are essential for a site to work; others are optional and are only used if you agree.
How we use them
We keep cookies to a minimum. Essential cookies are set because the site needs them. Anything optional stays switched off until you choose to allow it, and rejecting is as easy as accepting.

Analytics
We don’t currently use any analytics cookies. If that changes, they’ll be listed here and won’t be set unless you accept them.
If you accept analytics cookies, we use Google Analytics to see how the site is used — for example, which pages are visited most. It doesn’t identify you by name. These cookies are only set after you click “Accept”.

Third parties
The site loads its fonts from Google Fonts. This doesn’t set any cookies, but it does mean your browser shares your IP address with Google. See our privacy policy.
Managing cookies
You can change your choices at any time with the Cookie settings link at the bottom of every page. Most browsers also let you block or delete cookies in their settings, although blocking essential cookies may stop parts of a site from working.
Changes to this policy
We’ll update this page whenever the cookies we use change. The date at the top shows when it was last revised.
