Cookie Policy

Last updated: 27 April 2026

This Cookie Policy explains how Neurostead ("we", "us", "our") uses cookies and similar technologies on www.neurostead.co.uk (the "site"). It should be read alongside our Privacy Policy.

1. What are cookies?

Cookies are small text files that are placed on your device when you visit a website. They allow the site to recognise your device, remember your preferences, keep you signed in, and understand how the site is used. We also use similar technologies such as pixels, tags, local storage and SDKs - we refer to all of these as "cookies" in this policy.

2. Categories of cookies we use

Strictly necessary

These cookies are required for the site to work - for example, to keep your shopping basket, process payments, prevent fraud, and remember your cookie preferences. They cannot be switched off.

Analytics

These cookies help us understand how visitors interact with the site so we can improve it (for example, which pages are most viewed, where errors occur). We use Google Analytics 4 and Shopify's built-in analytics for this.

Marketing and advertising

These cookies help us measure the effectiveness of our advertising and show you relevant content on third-party platforms. We use the Meta (Facebook/Instagram) Pixel, the TikTok Pixel, and Klaviyo to do this.

4. Third-party cookies and international transfers

Some cookies are set by third parties (Google, Meta, TikTok, Klaviyo, Shopify). These providers may process your data outside the UK, including in the United States. Where this happens, we rely on appropriate safeguards as described in our Privacy Policy.

These third parties have their own privacy and cookie policies, which we recommend you read:

5. Your choices

When you first visit the site, our cookie banner asks for your consent to non-essential cookies. You can accept all, reject all (other than strictly necessary), or set granular preferences.

You can change your preferences at any time by clicking the "Cookie settings" link in the footer of the site.

You can also control cookies through your browser settings (for example, to block or delete cookies). Most browsers also offer a "Do Not Track" setting and private browsing mode. Disabling cookies may affect how the site works - for example, your basket may not be remembered between visits.

To opt out of personalised advertising, you can also use the tools provided by the IAB UK, the Network Advertising Initiative, and the Digital Advertising Alliance.

6. Changes to this policy

We may update this Cookie Policy from time to time to reflect changes to the cookies we use or for legal and regulatory reasons. The "Last updated" date at the top shows when it was last revised.
