Cookie Policy

Cookies are small text files that a website places on your device when you visit. They let the site remember you (so you don't have to log in again every time) and help us understand how the site is used so we can improve it. Similar technologies — like local storage and pixel tags — work in the same way and are covered by this policy.

Strictly necessary

Required for the site to work. They keep you signed in, keep items in your cart, remember your selected city, and protect checkout from fraud. You cannot turn these off.

Functional

Remember preferences such as your language, font-size, and whether you have dismissed certain banners. Disabling these may make parts of the site less personalised.

Analytics

Help us understand which tests are popular, how visitors navigate the site, and where there are pain points. The data is aggregated and does not identify you personally.

Marketing

Allow us to measure the effectiveness of campaigns and show you more relevant content on other platforms (such as retargeting). We do not share clinical or report data with marketing partners.

Some cookies are set by services we embed — for example, Google Maps for centre directions, our payment gateway for checkout, and analytics providers. Those cookies are governed by the providers' own policies, and we link to them where required.

You can control cookies in two places:

• The cookie banner shown when you first visit the site lets you accept or reject non-essential cookies. You can reopen the preference panel from the footer at any time.
• Your browser settings let you block or delete cookies for specific sites or in general. Helpful guides for Chrome, Firefox, and Safari are linked here.

Blocking strictly necessary cookies will break parts of the site (you may not be able to log in or check out).

We may update this policy as our use of cookies evolves. The "Last updated" date at the top of the page reflects the most recent change. We will surface material changes in our cookie banner.
