Privacy Policy

Last updated: November 4, 2026

WUYIN is operated by KEYUAN TRADING LIMITED (“WUYIN,” “we,” “us,” or “our”). This Privacy Policy explains how we handle personal information when you browse www.wuyinworld.com (the “Site”), place an order, contact our team, or otherwise interact with our online store.

If you have questions about this policy or your personal information, please email wuyinworks@gmail.com.

1. Information We Collect

The information we collect depends on how you interact with WUYIN.

Contact and delivery information. When you make a purchase or contact us, we collect information such as your name, email address, telephone number, billing address, and delivery address.

Order and payment information. We process details about the products you order, selected sizes or options, purchase history, payment status, deliveries, returns, and refunds. Payment providers collect the payment details needed to complete your transaction. The information available to us depends on your chosen payment method and provider.

Account information. If you create or use a customer account, we process the information associated with that account, including your contact details, order history, and saved preferences.

Messages and materials you send us. We collect the information you include in enquiries, customer service messages, feedback, and any photographs or other materials you choose to provide.

Device and browsing information. When you visit the Site, our store infrastructure and enabled tools may collect your IP address, browser and device type, cookie identifiers, referring pages, and information about your interactions with products, pages, and checkout.

We receive information directly from you, automatically through the Site, and from providers supporting payments, delivery, store operations, and other services described in this policy.

Information required to process an order will be identified during checkout. If you do not provide the necessary details, we may be unable to complete your purchase or arrange delivery.

2. Why We Use Your Information

We use personal information to:

• Process purchases, confirm payments, and deliver orders.
• Manage customer accounts and remember shopping preferences.
• Answer product questions and provide assistance with sizing, deliveries, returns, refunds, and other enquiries.
• Send order confirmations, delivery updates, and other service messages.
• Understand store performance and improve navigation, product information, and customer service.
• Send news about WUYIN products, releases, and offers in accordance with your preferences and applicable marketing rules.
• Support advertising and measure campaign performance where relevant tools are enabled.
• Identify suspicious transactions, investigate misuse, and protect our customers and business.
• Maintain business records, meet legal requirements, and handle disputes.

Where European or UK data protection law applies, the legal basis depends on the activity. Order fulfilment relies on performing our contract with you; statutory recordkeeping relies on legal obligations; appropriate store administration and security activities may rely on legitimate interests, subject to your rights. We rely on consent where required, including for relevant marketing or tracking activities.

3. Shopify and Other Service Providers

Our online store runs on Shopify. Shopify processes information associated with browsing, checkout, and orders to support the operation of our store. Some Shopify services you choose to use may also involve processing governed by Shopify’s own privacy notices.

You can learn more through the Shopify Consumer Privacy Policy and Shopify Privacy Portal.

We also disclose relevant information to providers that help us operate WUYIN, including:

• Payment providers handling transactions and refunds.
• Delivery companies and fulfilment providers arranging shipments.
• Technology providers supporting hosting, store functionality, communications, and customer service.
• Analytics and advertising providers, where their tools are enabled and subject to applicable requirements.

The information disclosed depends on the service involved. For example, a delivery company needs recipient and shipping details to deliver your order.

We may also disclose information where legally required, to address fraud or legal claims, or as part of a business sale, merger, or restructuring, subject to applicable protections.

4. Cookies, Analytics, and Advertising

We use cookies and similar technologies to support store functions such as shopping carts, checkout, security, and remembering preferences.

Depending on the tools enabled on the Site, these technologies may also help us understand browsing activity, measure advertising results, and display relevant advertisements. Information involved may include device identifiers, pages viewed, product interactions, and purchase events.

Certain disclosures to advertising providers may be treated as a “sale,” “sharing,” or processing for “targeted advertising” under applicable privacy laws. The classification depends on the activity and the law that applies.

You can manage or delete cookies through your browser settings. Blocking certain cookies may affect account access, checkout, or other store functions. Browser cookie settings do not necessarily stop every type of information disclosure.

For questions about these activities or to submit an applicable privacy request, contact wuyinworks@gmail.com.

5. Marketing Preferences

Where permitted and consistent with your preferences, we may use your contact information to send WUYIN product news, release announcements, and promotional offers.

You can unsubscribe from promotional emails using the unsubscribe link included in those messages or by contacting us.

Unsubscribing from marketing does not prevent us from sending messages needed to manage your orders, respond to an enquiry, or provide essential account information.

6. International Processing

WUYIN is operated by a company based in Hong Kong. Our online store uses international service providers, and Shopify’s hosting location shown for our store is the United States.

Your information may therefore be accessed, stored, or otherwise processed outside your country of residence. Privacy laws in those locations may differ from those in your home country.

International processing remains subject to applicable data protection requirements, including transfer safeguards where required. Please contact us if you would like information about the locations or safeguards relevant to your information.

7. Retention and Security

We retain personal information for the time needed for the purposes described in this policy, taking account of the nature of the information and applicable requirements.

For example, order and payment records may need to be retained for accounting, tax, warranty, or dispute purposes. Customer service records may be retained to resolve an enquiry and maintain a record of its outcome. We may keep limited information needed to respect an unsubscribe or other privacy choice.

When information is no longer required, we take appropriate steps to delete it or remove its identifying characteristics, subject to legal retention requirements.

We take reasonable measures to protect personal information against unauthorised access, loss, and misuse. However, internet transmission and electronic storage involve risks, and absolute security cannot be guaranteed. Please avoid sending full payment card details or other unnecessary sensitive information by email.

8. Your Privacy Rights

Depending on your location, the applicable law, and our processing activities, you may have rights to:

• Obtain information about how your personal information is used and request access to it.
• Correct inaccurate or incomplete information.
• Request deletion of information, subject to applicable exceptions.
• Receive certain information in a portable format.
• Object to or restrict certain processing activities.
• Withdraw consent where processing relies on consent.
• Opt out of activities legally defined as the sale or sharing of personal information or targeted advertising.
• Limit certain uses of sensitive personal information, where that right applies.

European and UK residents may have additional protections concerning decisions based solely on automated processing that produce legal or similarly significant effects. Information about European rights is available from the European Commission. California residents can consult the California Attorney General’s privacy guidance.

To submit a request, email wuyinworks@gmail.com and describe what you would like us to do. We may need information reasonably necessary to verify your identity. Where permitted, an authorised representative may submit a request with appropriate evidence of authority.

We will handle requests within the periods required by applicable law. Some requests may be subject to exceptions, which we will explain where required. We will not unlawfully discriminate against you for exercising your rights.

You may also contact us with a complaint, appeal a decision where applicable, or raise a concern with the relevant privacy regulator.

9. Children’s Privacy

The Site is not directed to children under 16, and we do not knowingly collect their personal information.

If you believe a child has provided personal information to us, please contact wuyinworks@gmail.com so that we can investigate and take appropriate action.

10. External Websites

The Site may contain links to social platforms or other websites operated by third parties. Their information practices are governed by their own privacy policies. Please review those policies before providing information to them.

11. Policy Updates

We may revise this policy when our services, information practices, or legal requirements change.

The current version will appear on the Site with an updated date. Where required, we will provide additional notice or request consent for relevant changes.
