Terms of Service

Last updated: 2026-07-22

This English text is provided for reference. The Japanese利用規約 is the authoritative version; in case of any discrepancy, the Japanese text prevails.

These Terms of Service ("Terms") govern use of the AI management-advisory service "zoro" (the "Service") provided by Yuya Narikawa, doing business as Partner System ("we", "us", "our"). By using the Service, you agree to be bound by these Terms.

1. The Service

The Service is a chat-based service that uses AI to provide information and advice on business management. Any advice the Service provides is reference information; management decisions and other choices are made at your own responsibility and discretion.

The Service does not provide advice on matters reserved to licensed professionals — such as tax accountants, lawyers, and labor and social-security consultants — including tax calculations, specific legal advice, and individual labor determinations. For these, please consult a qualified professional yourself.

2. Accounts and invitations

The Service is currently offered by invitation only. You register an account by the method we specify.

• Provide accurate, up-to-date registration information.
• You are responsible for safeguarding your account and credentials. Lending or sharing them with third parties is not permitted.
• Actions taken through your account are deemed to be your actions.

3. Fees and payment

The fee for the Service is ¥50,000 per month (tax included). Payment is by credit card processed through Stripe.

Credits

• 100 credits are granted each month.
• Each conversation consumes 1, 3, or 5 credits depending on how involved it is.
• If you run out, you may purchase additional credits.
• Unused granted credits do not roll over to later months and cannot be exchanged for cash.

Refunds

Monthly fees already begun and additional credits already purchased are generally non-refundable, except where a refund is required by law.

4. Cancellation

You may cancel at any time. Cancellation takes effect at the next renewal date, and billing stops from that renewal onward. No pro-rated refund is given for fees already incurred.

5. Prohibited conduct

In using the Service, you must not:

• Violate any law or public order and morals.
• Misuse the Service, improperly obtain credentials, or lend your account to third parties.
• Reverse-engineer, decompile, or disassemble the Service or its components, except as permitted by law.
• Send large volumes of automated requests or otherwise interfere with the operation of the Service.
• Re-provide information obtained through the Service to third parties as professional advice.
• Infringe the rights of us or any third party.

6. Disclaimer

Advice provided by the Service is reference information. We make no warranty as to its accuracy, completeness, or fitness for a particular purpose, nor as to the outcome of any management decision you make based on the Service.

The Service does not provide tax, legal, labor, accounting, or other professional determinations. Where such judgment is needed, always consult a qualified professional. Except in cases of our willful misconduct or gross negligence, we are not liable for damages arising from your use of, or inability to use, the Service.

Where we do bear liability, it is capped at the amount of fees you paid us in the month the damage occurred. Where our liability cannot be limited under mandatory law (such as consumer-protection law), that law governs.

7. Intellectual property

Intellectual property rights in the Service and its software, design, and "advisor skills" belong to us or the rightful owners. Rights in the content and files you input belong to you; we use them only as needed to provide and improve the Service.

8. Changes to and suspension of the Service

With prior notice to users, we may change, suspend, or discontinue the Service. For maintenance, faults, or other unavoidable reasons, we may suspend it temporarily without prior notice.

9. Governing law and jurisdiction

These Terms are governed by the laws of Japan. Any dispute arising between us and a user shall be subject to the exclusive jurisdiction of the court having jurisdiction over our location as the court of first instance.

10. Changes to these Terms

We may revise these Terms as needed. Revised Terms take effect when posted on this page. Continued use after a revision constitutes acceptance of the revised Terms.
