Privacy Policy

Effective date and last updated: September 12, 2026

Zhumadian Kaijin Technology Co., Ltd., operator of Wumzev, is responsible for the personal information described in this Privacy Policy. This policy explains what we collect, why we use it, when we disclose it and the choices available to you.

1. Information We Collect

Depending on how you use the store, we may collect contact and account information; order, delivery and transaction details; communications with customer support; device, browser, IP address and usage information; cookie or similar technology data; and advertising attribution information. Payment card details are processed by payment providers and are not stored by us in full.

2. How We Use Information

We use information to operate the storefront, process transactions, fulfill and deliver orders, provide support, prevent fraud or misuse, maintain security, improve products and site performance, comply with legal obligations, and send marketing where permitted by law or with required consent.

3. Cookies and Similar Technologies

Shopify and other service providers may use cookies, pixels, SDKs or similar technologies for essential storefront functions, preferences, analytics, security, advertising and attribution. Where consent is legally required, non-essential technologies should be used only after the applicable choice is made. You may use available cookie controls, browser settings and recognized preference signals to manage eligible technologies.

4. Advertising and AppLovin

When Wumzev uses AppLovin advertising services, AppLovin and participating partners may process device identifiers, IP address, ad interaction events, conversion events and related attribution information under their own terms and privacy notices. We use this information to measure campaigns and avoid misleading or irrelevant advertising. We do not use AppLovin to target advertising to children.

5. How We Disclose Information

We may disclose information to Shopify; payment processors; shipping, fulfillment and delivery providers; website hosting, security and customer-support providers; analytics, advertising and attribution partners; professional advisers; authorities where legally required; and a successor in a legitimate business transaction. These parties may act as processors, service providers or independent controllers depending on the service and applicable law.

6. Sale, Sharing and Targeted Advertising Choices

We do not exchange personal information for money. Certain advertising or analytics disclosures may be treated as a “sale,” “sharing,” or targeted advertising under some privacy laws. Where applicable, review Your Privacy Choices, email service@wumzev.com with the subject “Privacy Choice,” or use available cookie and browser preference controls. We process legally recognized opt-out preference signals where required.

7. Your Privacy Rights

Depending on your location, you may have rights to access, correct, delete, restrict or object to processing, receive a portable copy, withdraw consent, or appeal a decision. To make a request, email service@wumzev.com. We may need to verify your identity and authority before completing the request.

8. International Processing

Because our service providers and customers may be located in different countries, information may be processed outside your place of residence. Where required, appropriate safeguards are used for international transfers.

9. Retention and Security

We retain information only as long as reasonably necessary for the purposes described above, including transaction records, legal obligations, dispute resolution and security. We use reasonable administrative, technical and organizational safeguards, but no method of transmission or storage is completely secure.

10. Children

The store is intended for a general adult audience and is not directed to children as defined by applicable law. We do not knowingly collect personal information from children for targeted advertising.

11. Third-Party Links

The site may link to third-party services. Their privacy practices are governed by their own notices, and we are not responsible for their independent practices.

12. Changes to This Policy

We may update this policy to reflect operational, legal or regulatory changes. The updated date at the top identifies the current version.
