    • browser, device and operating-system information;
    • website activity and browsing behaviour;

    Payment information is generally processed securely by our payment providers. We do not normally receive or store your complete payment-card details.

    How we use your information

    We may process your personal information for the following purposes.

    Processing and delivering orders

    We use information such as your name, contact details, delivery address and order information to:

    • process orders;
    • take payment;
    • send order confirmations;
    • arrange delivery;
    • process returns and refunds; and
    • provide customer support.

    Our lawful basis for this processing is generally that it is necessary to perform our contract with you.

    Customer accounts

    Where customer accounts are available, we use your information to create and maintain your account, display order information and provide account-related functionality.

    Our lawful basis is performance of our contract with you and our legitimate interests in providing an efficient customer experience.

    Customer service

    We use information you provide when contacting us to answer questions, investigate problems, deal with complaints and provide after-sales support.

    Our lawful basis may be performance of our contract with you, compliance with our legal obligations or our legitimate interests in operating our business and supporting customers.

    Legal and accounting obligations

    We may retain and use information where necessary to comply with tax, accounting, regulatory, product-safety, consumer-protection or other legal requirements.

    Our lawful basis is compliance with our legal obligations.

    Fraud prevention and security

    We may process information to protect GC18, our customers and our website against fraud, misuse, security threats and unauthorised transactions.

    Our lawful basis is our legitimate interest in protecting our business, customers and systems and, where applicable, compliance with legal obligations.

    Improving our website and business

    We may analyse how customers use our website and products to understand performance, improve our website, measure campaigns and develop our services.

    Where this requires non-essential cookies or similar tracking technologies, we will obtain consent where required.

    Marketing

    If you have agreed to receive marketing from us, we may use your email address and related information to send:

    • product news;
    • offers and discount codes;
    • launch information;
    • promotions;
    • competitions;
    • golf-related content; and
    • other GC18 marketing.

    Our email marketing is currently managed using Klaviyo.

    You can unsubscribe at any time using the unsubscribe link contained in our marketing emails or by contacting support@gc18.co.uk.

    Withdrawing marketing consent does not affect transactional communications such as order confirmations, delivery updates or important information about an existing order.

    Where permitted by law, we may also market similar GC18 products to existing customers using the applicable existing-customer marketing rules, provided the required opportunity to opt out has been provided.

    Cookies, analytics and advertising

    Our website uses cookies and similar technologies.

    These may include technologies provided through:

    • Shopify;
    • Google Analytics;
    • Meta/Facebook;
    • TikTok;
    • Klaviyo; and
    • other services used to operate, analyse and market our website.

    Strictly necessary technologies may operate without consent where permitted by law.

    Analytics, advertising and other non-essential tracking technologies are only used where the necessary consent has been obtained.

    Further information is contained in our Cookie Policy.

    We may share personal information where necessary with service providers including:

    • Shopify, which powers our online store;
    • Shopify Payments and associated payment-processing providers;
    • Stripe;
    • PayPal;
    • Apple Pay;

    • IT, hosting, security and infrastructure providers;
    • accountants, lawyers, insurers and professional advisers;
    • fraud-prevention and payment-security providers; and
    • regulators, law enforcement, courts and public authorities where legally required.

    We only share personal information where reasonably necessary for the relevant purpose.

    Some payment methods are provided directly by third-party providers and their own privacy terms may also apply.

    International transfers

    Some of our service providers operate internationally or may process information outside the United Kingdom.

    Where personal information is transferred internationally, we take steps intended to ensure an appropriate level of protection in accordance with applicable UK data-protection law.

    Depending on the destination and provider, this may include reliance on UK adequacy regulations or appropriate contractual safeguards such as the UK International Data Transfer Agreement or the UK Addendum to approved standard contractual clauses.

    How long we keep information

    We retain personal information only for as long as reasonably necessary for the purpose for which it was collected, including to satisfy legal, accounting, tax, regulatory and dispute-resolution requirements.

    For example:

    • order and transaction records may be retained for the period required under applicable tax and accounting law;
    • customer account information may be retained while an account remains active and for an appropriate period afterwards;
    • customer-service correspondence may be retained where reasonably necessary to deal with enquiries, disputes or legal issues;
    • marketing information may be retained until you unsubscribe or withdraw consent; and
    • we may retain limited suppression information after an unsubscribe so that we can continue to respect your marketing preference.

    Cookie and tracking retention periods vary depending on the technology used.

    Your rights

    Depending on the circumstances, UK data-protection law may give you rights to:

    • request access to your personal information;

    You also have the right to complain to the Information Commissioner's Office (ICO) if you are concerned about how your personal information has been handled.

    Security

    We use reasonable technical and organisational measures designed to protect personal information against accidental loss, misuse, unauthorised access, alteration or disclosure.

    No internet transmission or electronic storage system can, however, be guaranteed to be completely secure.

    GC18 products are not recommended for children.

    Our website and services are not designed for the deliberate collection of personal information from children.
