Terms of Service

Version 1.0 · Last updated: November 11, 2026

1. Acceptance of terms

Welcome to KnowPay ("KnowPay", "we" or "us"). This service is operated by Yinghuo Cross-border E-commerce (Shenzhen) Co., Ltd. under the laws of the People's Republic of China, with a registered address at B1001, Buildings 3-4, Huaguo Commercial Silicon Valley, Minkang Community, Minzhi Subdistrict, Longhua District, Shenzhen, China. These Terms of Service (the "Terms") apply to the digital products and services ("the Service") you access and purchase through https://knowpay.app, including the TikTok Shop Playbook (2026 Edition) (the "Playbook") and the Feishu/Lark-Based TikTok Shop Operations System (the "System").

By placing an order, making a payment, or otherwise using the Service, you confirm that: (a) you are at least 18 years old; (b) you have read, understood and agree to be bound by these Terms; (c) you agree to our Privacy Policy; and (d) you have authority to make these agreements on your own behalf or on behalf of the entity you represent.

2. Description of service

2.1 What we provide

KnowPay offers digital knowledge products for cross-border e-commerce operators: an online playbook, and an operations system that runs on Feishu/Lark Base. Product names, scope and prices are as shown on the pricing page and the respective product pages.

2.2 Nature of the service

All products sold through the Service are digital intangible goods delivered online: the Playbook is delivered as online reading access, and the System is delivered as a copyable template link. We email the access link within 1 business day of confirmed payment; because digital content cannot be recalled once delivered, refunds are limited as set out in Section 6.

3. Orders and eligibility

No account registration is required to purchase. When ordering, you must provide an accurate and complete email address that can receive mail — delivery and after-sales all go through that email. If you purchase on behalf of a company or organization, you represent that you are authorized to accept these Terms on its behalf.

4. Price, payment and taxes

4.1 One-time payment

Everything in this store is charged once. We do not offer subscriptions, trials that convert to paid plans, installments, or any form of automatic renewal. Completing a purchase authorizes us to charge the amount shown at checkout to your chosen payment method, once — no further charges will be made against that purchase.

4.2 Payment processing

Payments are processed by Waffo Pancake, a PCI-DSS-compliant payment processor. Full payment card data is handled by Waffo Pancake and is not stored on our servers.

4.3 Taxes

Unless stated otherwise, prices shown exclude any taxes that may apply (including VAT, GST or sales tax). Where applicable law requires, such taxes are calculated and charged at checkout.

4.4 Price changes

We may adjust prices or content at any time. The price that applies to your order is the amount displayed when you complete checkout.

5. Delivery

Once payment is confirmed, we email the access information (the Playbook reading link, or the System template link) to the address you entered at checkout within 1 business day — usually the same day. If you have not received it after one business day, check your spam folder first, then contact support@knowpay.app. We will resend it at no additional charge for the same order.

6. Refund policy

6.1 Playbook (TikTok Shop Playbook, 2026 Edition)

• Within 3 days of payment: full refund, no reason required.
• More than 3 days after payment: no refund.
• Once a refund is completed, reading access closes immediately.

6.2 System (Operations System)

The System is not refundable. Reason: as soon as the link is sent, the buyer can create a copy, and digital content cannot be recalled. To reduce your risk, you may email support@knowpay.app before purchase for the user guide and demo data preview.

6.3 General cases

• If we cannot deliver a product for reasons on our side, you receive a full refund.
• If a billing error causes duplicate charges, the duplicated amount is refunded in full.
• Where applicable law grants mandatory cancellation or refund rights (such as statutory consumer rights in some regions), we respect and honor them.

6.4 How to request

Email support@knowpay.app with your purchase email, order number and a short explanation. We confirm within 2 business days; approved refunds are returned via the original payment method within 5–10 business days.

7. Billing disputes

If you believe a charge is incorrect, please email support@knowpay.app first and talk to us before filing a dispute with your bank or card issuer. We commit to replying within 2 business days and resolving confirmed billing errors within 5 business days.

8. Intellectual property and license

8.1 Ownership

All content of the Playbook and the System (text, structure, field design, report logic, documentation) is independently developed by KnowPay and protected by copyright law.

8.2 License granted to you

• Playbook: during the 12-month access period, a personal, non-exclusive, non-transferable right to read, for your own learning.
• System: the right to create a copy in your own Feishu/Lark workspace, modify it, and use it for your own business — indefinitely.

8.3 Restrictions

Without our written consent, you may not: resell, sublicense, publicly distribute or mass-share the products; adapt or republish the Playbook's content as your own publication or paid training; or sell the System as a standalone product or template.

9. Acceptable use

You agree not to use the Service for:

• Any unlawful, fraudulent, defamatory or harassing purpose;
• Infringing third-party intellectual property or privacy rights;
• Circumventing or interfering with the Service's security mechanisms;
• Systematically scraping or exporting product content for redistribution;
• Violating applicable laws, regulations, or card network rules.

10. Third-party platforms and fees

The System runs on the Feishu/Lark platform. The price of the System covers only the template itself — that is, its structure and design. It does not include any fees charged by the Feishu/Lark platform itself, such as feature subscription fees, permission or seat fees, compute or AI usage fees, or the cost of any feature moving from free to paid. Such fees are set and collected by Feishu/Lark and are unrelated to this store.

Platform rules, policies and fees mentioned in the Playbook are subject to each platform's official publications. Platform changes may make parts of the Playbook outdated; we publish by edition to account for such changes.

11. Scope of after-sales support

• Broken System link, cannot create a copy: we resend the link.
• You modified your copy and it stopped working: we do not repair it, but you can obtain the link again and rebuild a clean copy.
• We do not provide modifications, customization or store-operation services tailored to your business.

12. Disclaimer and limitation of liability

12.1 Disclaimer

The Service and its products are provided "as is", without express or implied warranties, including merchantability or fitness for a particular purpose. The Playbook and the System offer methods, standards and tools; they do not constitute legal, tax, accounting or other professional advice, and we make no commitments regarding any specific business outcome, sales or income.

12.2 Limitation of liability

To the maximum extent permitted by applicable law, KnowPay is not liable for any indirect, incidental, consequential or punitive damages. Our total liability for any order is limited to the amount you actually paid for that order.

13. Term and termination

These Terms take effect when you use the Service and remain in force. We may suspend or terminate the Service to you if you materially breach these Terms, are involved in fraud, or where the law requires. If we terminate for reasons not caused by your breach, we will refund the unused portion on a pro-rata basis. You may ask us to delete your contact information at any time via support@knowpay.app.

14. Governing law and dispute resolution

These Terms are governed by the laws of the People's Republic of China. Before starting any formal proceedings, please email support@knowpay.app to attempt an amicable resolution.

15. Changes to these terms

We may update these Terms from time to time. Material changes will be announced on this page at least 14 days before taking effect, with the "Last updated" date revised. Continuing to use the Service after changes take effect constitutes acceptance of the updated Terms.
