Welcome to the products and services provided by Beijing Shadow Stitch Technology Co., Ltd. (“we,” “us,” or “our”), including the Coutto and Knitto mobile apps and the shadowstitch.ai website (collectively, the “Services”).

Please read these Terms of Service (“Terms”) carefully. By accessing, downloading, installing, or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

1. Description of Services

We provide tool apps and related online services for craft and creative workflows, including sewing pattern tools and knitting assistance. Features may vary by product version and platform. We may update, modify, or discontinue features at any time.

2. Eligibility

You must have the legal capacity to enter into these Terms. If you use the Services on behalf of an organization, you represent that you have authority to bind that organization. You agree to provide accurate information and keep your account and devices secure.

3. Accounts

Some features may require registration or sign-in. You are responsible for activity under your account and must not transfer, share, or misuse account access. Notify us promptly of unauthorized use.

4. License and Restrictions

We grant you a personal, non-exclusive, non-transferable, revocable, limited license to use the Services in accordance with these Terms.

You agree not to:

  • Use the Services unlawfully or in a way that infringes others’ rights
  • Reverse engineer, decompile, or attempt to extract source code except as permitted by law
  • Interfere with or disrupt the Services or related systems
  • Upload malware or harmful code
  • Use the Services for purposes unrelated to lawful craft and creative tooling

5. User Content and Intellectual Property

5.1 Your content

Patterns, images, project files, knitting data, and other materials you submit (“User Content”) remain yours or belong to their respective owners. You represent that you have the rights needed to use and share User Content through the Services.

5.2 License to us

You grant us a non-exclusive, worldwide, royalty-free license to host, store, process, transform, and display User Content only as necessary to operate and improve the Services. This license ends when you delete the content or stop using the relevant feature, except where retention is required by law.

5.3 Our IP

Software, interfaces, trademarks, logos, documentation, and other materials in the Services (excluding User Content) are owned by us or our licensors. You may not copy, modify, distribute, or exploit them without our written permission.

6. AI and Automated Features

The Services may include AI or automated assistance. Outputs are provided for informational purposes only and do not constitute professional, legal, or commercial advice. You are responsible for verifying important results (such as pattern dimensions or cutting parameters) before use.

7. Third-Party Services

The Services may link to or integrate third-party websites, SDKs, or services. Those third parties operate under their own terms and privacy practices. We are not responsible for their content, availability, or policies.

8. Payments and Subscriptions (If Applicable)

If paid features, subscriptions, or in-app purchases are offered in the future, pricing, billing cycles, refunds, and cancellation rules will be disclosed in the app or on our website. Unless required by law or explicitly stated, fees are generally non-refundable.

9. Disclaimer of Warranties

To the maximum extent permitted by law, the Services are provided “as is” and “as available.” We disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee uninterrupted, error-free, or fully compatible operation.

10. Limitation of Liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages arising from your use of the Services. Our total liability for any claim relating to the Services is limited to the greater of (a) amounts you paid us for the relevant Service in the past 12 months, or (b) USD $15 if the Service is free, unless a higher minimum is required by applicable law.

11. Termination

You may stop using the Services at any time. We may suspend or terminate access if you violate these Terms. Provisions that by nature should survive termination (including IP, disclaimers, and limitations of liability) will remain in effect.

12. Changes to These Terms

We may update these Terms from time to time. Material changes will be communicated through the app, website, or other reasonable means. Continued use after changes take effect constitutes acceptance.

13. Governing Law and Disputes

These Terms are governed by the laws of the People’s Republic of China, without regard to conflict-of-law rules. Disputes shall first be resolved through good-faith negotiation; if unresolved, they shall be submitted to a court of competent jurisdiction where we are located.
