Cookie policy

The short version

We use a small number of cookies to make the site work. Nothing used for analytics or advertising loads until you agree to it. If you decline, the site works exactly as it does otherwise — the preliminary plan included.

Strictly necessary

These are required for the site to function and cannot be switched off. They do not track you across other websites.

• Remembering your cookie choice, so you are not asked on every page
• Security measures protecting our forms from automated abuse
• Holding your progress through the preliminary plan while you complete it

Your preliminary plan answers are held in your browser’s session storage while you work through it, and are cleared when you close the tab unless you submit them.

Analytics

With your consent, we use analytics to understand which pages are useful and where people get stuck. We exclude health-related information from analytics entirely — what you select in the preliminary plan is never sent to an analytics provider.

The specific analytics providers, cookie names and retention periods must be listed here once configured.

Advertising

With your consent, we may use advertising cookies to measure whether our advertising reaches people it is useful to.

Providers and cookie details must be listed here before any advertising tag is enabled. We will not use health-related information for advertising targeting.

Changing your mind

You can change your cookie choice at any time from the link in the footer. You can also block or delete cookies in your browser settings, though blocking strictly necessary cookies may stop parts of the site working.

How we handle personal information generally is covered in our privacy policy.
