Cookie Policy

Last updated: 10 June 2026

This Cookie Policy explains how The Durham Genome Centre Ltd, trading as Chxhealth®, uses cookies and similar technologies on our website. It should be read together with our Privacy Policy.

1. What are cookies?

Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work, to improve performance, and to provide information to site owners. “Similar technologies” include pixels, tags and local storage, which perform comparable functions.

2. How we use cookies

We use cookies to operate our website and checkout, to understand how the site is used, and — only with your consent — to measure and personalise advertising. We group cookies into three categories:

Essential cookies (always on)

These are necessary for the website, your cart and the checkout to function. They cannot be switched off. Examples include cookies set by our platform provider, Shopify, to maintain your session, remember the contents of your cart, and process payments securely.

Analytics cookies (consent-based)

These help us understand how visitors find and use our website — for example which pages are visited and how people move through the site — so we can improve it. The data is used in aggregate.

Marketing cookies (consent-based)

These are used, with your consent, to measure the effectiveness of our advertising and to show you relevant ads on other platforms. This includes the Meta (Facebook/Instagram) pixel, which helps us understand whether visits or purchases resulted from our ads and to build audiences for advertising.

4. Managing your preferences

When you first visit our website, our consent banner lets you accept or decline non-essential cookies. You can change your choice at any time using the “Cookie preferences” link in the footer of our website.

You can also control cookies through your browser settings, including blocking or deleting cookies. Please note that if you disable essential cookies, parts of the website may not work properly.

5. Consent

We only set analytics and marketing cookies after you have given consent through our consent banner. Essential cookies are set on the basis that they are strictly necessary to provide the service you have requested. You can withdraw consent at any time as described above; this will not affect cookies already used before withdrawal.

6. Changes to this policy

We may update this Cookie Policy from time to time to reflect changes in the technologies we use or for legal reasons. We will post the updated version here and revise the “Last updated” date.
