What are cookies?
Cookies are small text files that a website stores on your device. They let a site remember you between page loads, keep forms working, and - with your consent - measure how the site is used so we can improve it.
Cookies we use
Essential cookies
A small number of first-party cookies are needed for the site and its forms to work - for example, a session cookie and a CSRF token that prevents form-submission abuse. These are set automatically and cannot be switched off.
Analytics cookies
We use Google Analytics 4 via gtag.js with measurement ID G-NNDZWX4J6F. This sets cookies (typically _ga and related) that help us count visitors, understand which guides are useful and diagnose problems. We do not use the data for advertising.
Advertising cookies
We do not currently use marketing or advertising cookies, and we do not sell your data to third-party advertisers.
How to manage cookies
You can control cookies in your browser settings - most browsers let you block cookies, delete cookies already stored, or be warned before one is set. Blocking essential cookies may stop parts of the site from working.
To opt out of Google Analytics across every site you visit, install Google’s opt-out browser add-on: tools.google.com/dlpage/gaoptout.
