1. What cookies we use

Strictly necessary cookies and local storage keep the site working — for example remembering that you are part way through a Builder Standard Assessment or that you are signed in to your account. These cannot be switched off without breaking the service.

Analytics and advertising measurement technologies help us understand how people find and use the site, including where a visitor came from when they arrive from an advertisement. These are only used where we have your consent or another lawful basis under UK law.

2. Campaign tracking

When you arrive from an advertisement or a link we have shared, we may store campaign parameters (such as utm_source or utm_campaign) for the duration of your visit so that we can attribute an enquiry to the right campaign. This information is stored in your browser's session storage and is cleared when you close the tab.

3. Controlling cookies

You can delete or block cookies through your browser settings. If you block strictly necessary cookies, parts of the site — including the Builder Standard Assessment and your account — may not work correctly.

4. Changes and contact

We may update this policy as the platform develops. If you have questions about how we use cookies or personal data, please contact us through the contact page. Our privacy notice explains your rights under UK GDPR.
