Cookies are small text files placed on your device to make websites work, improve performance, and provide insights for analytics and advertising. We also use pixels, tags, SDKs and local storage that operate similarly.

2. The laws that apply

We comply with the UK GDPR, the Data Protection Act 2018, and the Privacy and Electronic Communications Regulations (PECR). Where required, we obtain your consent before setting non-essential cookies and before processing personal data for personalised ads, in line with Google’s EU User Consent Policy.

On your first visit, we present a banner that lets you accept, reject, or manage cookie categories. You can review or change your preferences at any time.

• Google Analytics Opt-out Browser Add-on
• Google Ads Settings and My Ad Center
• YourOnlineChoices (EDAA)

Blocking some cookies may affect site functionality (e.g., cart/checkout).

8. Do we use third-party cookies?

Yes. Third parties (e.g., Google, Meta, Shopify apps) may set cookies to provide services, measure performance, and personalise ads. These providers may process your data outside the UK/EEA. Where they do, we ensure appropriate safeguards (such as Standard Contractual Clauses).

9. How long do we keep cookie data?

Retention depends on the cookie type and purpose (see the table above). Analytics and advertising cookies typically expire after 24 hours to 2 years. Local storage persists until you clear it or update your preferences.
