Cookie Policy

First published March 2018 · Last reviewed January 2026

This policy explains what cookies are, which ones this website uses, and how you can control them. It should be read alongside our Privacy Policy.

What cookies are

Cookies are small text files a website stores on your device. They let a site remember your actions and preferences over time, and help site owners understand how their pages are used. Some are strictly necessary; others are optional and only set with your consent.

Cookies we use

Strictly necessary

These are required for the site to function and cannot be switched off. They include the cookie that records your cookie-consent choice, so we don't ask you again on every page. No consent is required for these, and they store no personal data.

Analytics (optional)

With your consent, we use privacy-respecting analytics to count visits and understand which pages are useful. This data is aggregated and does not identify you personally. If you decline, these cookies are not set.

How we ask for consent

When you first visit, a banner lets you accept or decline optional cookies. Your choice is stored locally in your browser. If you decline, only strictly necessary cookies are used.

Managing cookies

You can change your choice at any time by clearing this site's data in your browser, which will bring the consent banner back.
Most browsers let you block or delete cookies through their settings. Note that blocking strictly necessary cookies may stop parts of the site working.
Guidance for common browsers is available on their respective support sites.

Changes to this policy

If the cookies we use change, we will update this page and the "last reviewed" date above.
