This Cookie Policy explains how Genefluence Limited (“Genefluence”, “we”, “us” or “our”) uses cookies and similar technologies when you visit genefluence.com.
It should be read alongside our Privacy Policy, which explains more broadly how we collect, use and protect personal information.
What are cookies?
Cookies are small text files that are placed on your computer, phone or other device when you visit a website.
Cookies help websites function properly, remember choices you have made and provide information about how visitors use a website. Similar technologies, including pixels, tags, scripts and browser storage, may be used for comparable purposes.
Some cookies last only for the duration of your visit. These are known as session cookies. Others remain on your device for a set period or until you delete them. These are known as persistent cookies.
How we use cookies
We use cookies and similar technologies to:
- operate our website, shopping basket and checkout;
- maintain the security and integrity of the website;
- remember your preferences and privacy choices;
- understand how visitors use the website;
- improve the performance and usability of the website;
- operate our email sign-up forms and measure engagement with our communications; and
- support marketing and personalisation where you have agreed to this.
Types of cookies we use
Strictly necessary cookies
These cookies are required for the website to operate. They support functions such as navigation, security, shopping baskets, checkout, payment services and remembering your privacy choices.
Because these cookies are necessary to provide the website and services you request, they cannot normally be switched off using our cookie preference controls.
Analytics and performance cookies
These cookies help us understand how people use the website, including which pages are visited, how visitors reached the website and whether any errors occurred.
The information helps us improve the website, its content and the customer experience.
Where consent is required, we use these cookies only after you have accepted them through our cookie banner or preference controls.
Functional cookies
Functional cookies allow the website to remember choices you make, such as your location, language, currency or other preferences.
Some functional cookies may be necessary to provide a feature you have specifically requested. Others will be used only where you have provided consent.
Marketing cookies
Marketing cookies and similar technologies may be used to understand engagement with our marketing, personalise communications and measure the effectiveness of campaigns.
Where consent is required, these technologies are not activated unless you accept marketing cookies.

Cookie names, purposes and durations may change when Shopify, Klaviyo or our website functionality is updated.
Shopify
Our online store is hosted by Shopify. Shopify places cookies needed to operate the store, shopping basket, checkout, payment features, security services, privacy preferences and analytics.
Shopify may process information collected through these technologies on our behalf or as otherwise described in Shopify’s privacy documentation.
Klaviyo
We use Klaviyo to provide website sign-up forms, manage email communications and understand engagement with those communications.
When Klaviyo’s onsite technology is enabled, it may use a cookie to recognise a browser after a visitor has identified themselves—for example, by completing a sign-up form or following a link in one of our emails.
The information may be used to understand website activity, personalise communications and measure email performance, subject to your consent choices and applicable law.
Your cookie choices
When you first visit our website, you may be shown a cookie banner that allows you to accept, reject or manage non-essential cookies.
You can change your decision later using the Cookie Preferences link available in the footer of our website.
Withdrawing consent does not affect the lawfulness of processing that took place before consent was withdrawn.
Strictly necessary cookies will continue to operate because they are required to provide the website and services you request.
Browser settings
Most internet browsers allow you to view, delete or block cookies using their settings.
Blocking all cookies may affect the operation of the website. For example, you may be unable to add products to your basket, complete checkout, sign in or use certain website features.
Instructions for managing cookies can normally be found in your browser’s privacy or security settings.
Third-party websites
Our website may contain links to websites operated by other organisations.
Those websites may use their own cookies or similar technologies. We are not responsible for their cookie practices, and you should review the cookie and privacy information provided by the relevant third party.
Changes to this policy
We may update this Cookie Policy when our website, service providers or legal obligations change.
The date at the top of this page shows when the policy was most recently updated.
