Privacy Policy

Last updated: 2026-07-22

This English text is provided for reference. The Japaneseプライバシーポリシー is the authoritative version; in case of any discrepancy, the Japanese text prevails.

Yuya Narikawa, doing business as Partner System ("we", "us", "our"), handles the information collected in providing the AI management-advisory service "zoro" (the "Service") in accordance with this policy. This policy explains, in line with actual practice, what information we collect, how we use it, what we transmit externally, and how we store and delete it.

Information we collect

• Account information — such as name, email address, and company name provided at registration.
• Conversation content — the text you enter into the Service and the business context accumulated in your "company dossier".
• Attachments — files you upload with a question.
• Payment information — payments are processed by Stripe. Card numbers are handled by Stripe; we do not retain card numbers. We access only limited information provided by Stripe, such as payment success/failure and billing status.
• Usage logs — access records for operating, maintaining, and preventing abuse of the Service.

Purposes of use

• Providing the Service — generating answers and maintaining context via the "company dossier".
• Account management, billing, and payment.
• Improving service quality, handling faults, and preventing abuse.
• Responding to your inquiries.

External transmission

To provide the Service, we use the following external services.

• Answer generation (Anthropic, United States) — the conversation content and attachments you enter are transmitted to the API of Anthropic, PBC(United States) in order to generate answers. Transmitted data is handled under Anthropic's policies and our API settings, and its retention period follows Anthropic's settings. This means your information is transferred outside Japan (to the United States).
• Infrastructure (Cloudflare) — we use Cloudflareto deliver and protect the Service.
• Payment (Stripe) — we use Stripe to process payments.

Storage and backup

Account information, conversation content, the company dossier, and attachments are stored in an environment we manage, only to the extent needed to provide the Service, and are backed up against loss. We take reasonable security measures to prevent unauthorized access, leakage, and alteration.

Deletion on withdrawal

When you withdraw from the Service, the account information, conversation content, company dossier, and attachments we hold for you are deleted within a reasonable period, except for information we are required to retain by law. Deletion from backups may take some time. Retention of data already transmitted to external services such as Anthropic follows each service's policies and settings.

Your rights

You may request disclosure, correction, suspension of use, or deletion of the information we hold about you. To do so, contact us at the address below. We will respond in accordance with the law after verifying your identity.

Changes to this policy

We may revise this policy as needed. Revised content applies when posted on this page. We will notify you of significant changes within the Service or by email to your registered address.
