Last updated: 24 August 2026
This policy explains what cookies are, which ones this website uses, and how you can control them.
What are cookies?
Cookies are small text files placed on your device when you visit a website. They're widely used to make websites work more efficiently, and to provide information to the site owner, such as how visitors use the site.
Cookies we use
We use Google Analytics to understand how visitors find and use this website, so we can improve it. Google Analytics sets the following cookies:
| Cookie | Purpose | Expiry |
|---|---|---|
| _ga | Distinguishes unique visitors, used to calculate visitor, session, and campaign data | 2 years |
| _ga_* | Used by Google Analytics 4 to persist session state | 2 years |
| _gid | Distinguishes unique visitors | 24 hours |
We do not currently use any advertising or marketing cookies, and we do not sell data collected through these cookies to third parties.
Strictly necessary cookies
This website does not currently set any strictly necessary cookies, such as login or session cookies, as it does not require you to create an account.
Managing cookies
You can control and delete cookies through your browser settings. Most browsers let you refuse cookies, delete existing ones, or ask to be notified before a cookie is set. Blocking analytics cookies won't stop you using this website, but it will mean we can't see anonymised data about your visit.
You can also opt out of Google Analytics specifically using Google's Analytics opt-out browser add-on.
Changes to this policy
If the cookies this website uses change, for example if we add new tools in future, we'll update this page.
