Cookie policy

Last updated: 4 October 2026

Cookies are small files that a website stores on your device. This page lists the ones we use and explains how to control them.

Your choice

Essential cookies are always on because the site cannot work safely without them. Analytics cookies are off unless you choose "Accept analytics cookies" in the cookie banner. You can change your mind at any time using the Cookie settings link at the bottom of every page.

Essential cookies

NamePurposeExpires
sn_sessionKeeps forms secure against forgery and keeps administrators signed in. It does not track you between sites.When you close your browser
sn_consentRemembers whether you accepted or rejected analytics cookies, so we do not ask on every page.6 months

The site also keeps copies of its design files (styles, fonts and icons) in your browser's storage so that pages load quickly. These contain no personal information.

Analytics cookies (only if you accept)

We use Google Analytics to understand how people use the site so that we can improve it. It tells us things like which pages are visited, how long for, and the type of device used. It does not tell us who you are.

NamePurposeExpires
_gaSet by Google Analytics to tell visitors apart.2 years
_ga_<ID>Set by Google Analytics to keep track of a visit.2 years

If you reject analytics cookies, or withdraw your consent later, Google Analytics is not loaded and we remove its cookies from this site.

Other websites

When you follow a link to donate you leave this site for Stripe, which sets its own cookies under its own policy. The same applies to any other external site we link to.

Controlling cookies in your browser

You can also block or delete cookies in your browser settings. If you block essential cookies, our forms will not work.

See our privacy policy for how we handle personal information.
