Terms of Service

Last updated: October 14, 2026

These Terms of Service ("Terms") govern your access to and use of ReviewKiln (the "Service"), operated by Li Weifeng ("we", "us", "our"), located in China. By creating an account or using the Service, you agree to these Terms. If you use the Service on behalf of a company, you confirm you are authorized to bind it, and "you" refers to that company. Contact: support@withchandra.com.

1. The Service

ReviewKiln is a software-as-a-service tool for e-commerce sellers that analyzes product reviews you provide (by CSV upload or pasted text) to produce insights such as complaint and defect clusters, praised features, competitor comparisons, and AI-generated listing drafts (titles, bullet points, descriptions). Future features may include a paid API/MCP endpoint, which may be subject to additional terms.

ReviewKiln does not collect data from Amazon or any other marketplace on your behalf. ReviewKiln is independent and is not affiliated with, endorsed by or sponsored by Amazon, Shopify, Helium 10 or any other platform or tool mentioned on our website.

2. Eligibility and accounts

You must be at least 18 years old and use the Service for business or professional purposes. You are responsible for keeping your login credentials secure and for all activity under your account. Notify us promptly at support@withchandra.com of any unauthorized use.

3. Your content

3.1 Ownership. You keep all rights to the reviews and other content you upload ("Customer Content") and to the outputs generated for you ("Outputs"), to the extent permitted by law.

3.2 License to us. You grant us a worldwide, non-exclusive, royalty-free license to host, copy, process, transmit and display Customer Content solely to provide, secure and support the Service, including sending it to our AI subprocessors as described in our Privacy Policy. We do not use Customer Content to train AI models.

3.3 Your responsibilities. You represent that (a) you have all rights and permissions needed to upload and process Customer Content; (b) you obtained it lawfully and in compliance with the terms of the platform it came from (for example, you did not obtain it through scraping prohibited by that platform); and (c) its processing by us does not violate any law or third-party rights, including privacy and data-protection laws. You should not upload unnecessary personal data, sensitive personal data, or confidential information of third parties.

4. AI-generated outputs

Outputs are generated automatically and may be inaccurate, incomplete or similar to outputs generated for others. You are responsible for reviewing Outputs before use and for ensuring that any listing content you publish is truthful, not misleading and compliant with the policies of the marketplace or platform you sell on and with applicable advertising and consumer-protection laws. We do not guarantee any particular business result, ranking or sales performance.

5. Acceptable use

You agree not to: (a) use the Service to violate any law or the terms of any third-party platform; (b) upload malware or content that is unlawful, infringing or abusive; (c) attempt to access the Service or its data by unauthorized means, or interfere with its operation; (d) reverse engineer the Service except where permitted by law; (e) resell or provide the Service to third parties except as permitted by your plan (e.g., agency/white-label use on Pro); (f) use automated means to create accounts or exceed usage limits; (g) use Outputs to generate fake reviews or deceptive content. We may suspend or terminate accounts that violate this Section.

6. Plans, payments and Merchant of Record

6.1 Creem. Our order process is conducted by our online reseller Creem, which acts as the Merchant of Record for all orders. Creem handles checkout, payment processing, invoicing, sales tax/VAT collection and remittance, and related customer service inquiries about payments. By purchasing, you also agree to Creem's terms and privacy policy presented at checkout.

6.2 Subscriptions. Paid plans are billed in advance on a monthly or annual basis and renew automatically until cancelled. Prices and plan limits (such as number of products, reviews analyzed and listing drafts) are shown on our Pricing page. Unused quota does not roll over unless stated otherwise.

6.3 Price changes. We may change prices or plan limits for future billing periods with at least 14 days' notice by email or in-app. Changes take effect at your next renewal; if you don't agree, you can cancel before then.

6.4 Upgrades and downgrades. Upgrades take effect immediately (prorated where supported by Creem). Downgrades take effect at the start of the next billing period.

6.5 Taxes. Prices may exclude taxes; applicable taxes are calculated and collected by Creem at checkout.

7. Cancellation

You can cancel your subscription at any time, directly in the app under Settings → Billing → Cancel subscription (or through the Creem customer portal linked there). No email or call is required. After cancellation, your plan remains active until the end of the current paid period and will not renew. Refunds are governed by our Refund Policy, which forms part of these Terms.

8. Free plan and free reports

We may offer a free plan or free reports with limited features. We may change or discontinue free offerings at any time and may limit free usage to prevent abuse (for example, one free report per person or business).

9. Data deletion and account closure

You can delete Customer Content and close your account at any time in the app. We delete data as described in our Privacy Policy. Before closing your account, export any reports you wish to keep.

10. Intellectual property

The Service, including its software, design, text and trademarks, is owned by us or our licensors and protected by law. Except for the limited right to use the Service under these Terms, no rights are granted to you. If you send us feedback, we may use it without obligation to you.

11. Third-party services

The Service relies on third-party providers (e.g., hosting, AI model providers, payment processing by Creem). We are not responsible for third-party services beyond our obligations under applicable law and our Privacy Policy.

12. Availability and changes

We aim for high availability but do not guarantee the Service will be uninterrupted or error-free. We may modify features; if we materially reduce core functionality of a paid plan during your billing period, you may cancel and request a prorated refund for the unused portion.

13. Disclaimer

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE AND OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. Nothing in these Terms limits rights you have under mandatory consumer-protection laws.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, (A) WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, SALES, DATA OR GOODWILL; AND (B) OUR TOTAL LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE IS LIMITED TO THE AMOUNT YOU PAID FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR USD $100 IF YOU HAVE NOT PAID. These limits do not apply to liability that cannot be limited by law, such as for fraud, gross negligence or wilful misconduct.

15. Indemnity

You will defend and indemnify us against third-party claims arising from your Customer Content, your use of Outputs, or your breach of these Terms or applicable law (including the terms of third-party platforms).

16. Termination

You may stop using the Service at any time. We may suspend or terminate your access if you materially breach these Terms, fail to pay, or if required by law, with notice where reasonable. Sections that by their nature should survive (e.g., 3.3, 4, 10, 13–15, 17) survive termination.

17. Governing law and disputes

These Terms are governed by the laws of People's Republic of China, without regard to conflict-of-laws rules. Disputes will be resolved in the courts of Handan, China, unless mandatory law in your country of residence provides otherwise. Before filing a claim, please contact us at support@withchandra.com so we can try to resolve it informally within 30 days.

18. Changes to these Terms

We may update these Terms. We will notify you of material changes at least 14 days in advance by email or in-app. Continued use after the effective date means you accept the updated Terms.

19. Miscellaneous

These Terms, together with the Privacy Policy and Refund Policy, are the entire agreement between you and us regarding the Service. If any provision is unenforceable, the rest remains in effect. Failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition or sale of assets.
