What cookies are
Cookies are small text files placed on your device when you visit a website. They help the site work properly, remember your choices, and let us understand how the site is being used.
How we use cookies
We use cookies for three things: to make the site work, to understand how people use it, and to measure our advertising.
Only the first of these happens automatically. Analytics and advertising cookies are not set unless you agree to them.
Essential cookies

Cookies we no longer use
We previously used Hotjar, which recorded how people moved around the site. We removed it in August 2026 and it no longer sets any cookies. If an old Hotjar cookie is still sitting on your device from before then, it is not doing anything, and clearing your cookies in your browser will remove it.
Your choices
When you first visit our site you can accept all cookies, reject all non-essential cookies, or choose category by category. Rejecting is as easy as accepting.
You can change your mind at any time using the Cookie settings link in our footer.
We will ask you again after 12 months, or sooner if the cookies we use change.
You can also block or delete cookies through your browser settings. In Chrome, Edge and Firefox these are under Settings, then Privacy; in Safari, under Settings, then Privacy; on a phone, in your browser app's settings. Blocking the essential cookies will stop parts of the site working properly, including keeping you signed in on our site.
Cookies set by other companies
Google Analytics and Google Ads are provided by Google, who set the cookies listed above. We do not control these cookies. Google's privacy policy explains how they use the information: https://policies.google.com/privacy
Your course is hosted on Circle, which sets its own cookies under its own policy.
If you follow a link from our site to another website, that site sets its own cookies under its own policy. This policy does not cover them.
Where your data goes
Some of the companies whose cookies appear on this site are based outside the United Kingdom, including Wix, who host our website, and Google. Information collected through their cookies may be processed outside the UK. Both apply safeguards for these transfers, which are described in their own privacy policies. Our Privacy Policy explains how we handle international transfers more generally.
Keeping this policy accurate
We check which cookies our site sets on a regular basis and update this page whenever they change. The date at the top tells you when it last changed.
