Privacy Policy for Fugu AI – Sakana Fugu (fugubysakana.store)

Last updated: January 1, 2026

This Privacy Policy explains how Fugu AI (Sakana Fugu), operated by Sakana AI, collects, uses, discloses, and protects your information when you visit our website at fugubysakana.store or use our API services, including the standard Fugu and Fugu Ultra orchestration models. By accessing or using our services, you agree to the practices described in this policy.

1. Information We Collect

We collect information to provide and improve our AI orchestration services. This includes:

  • Account Information: When you register for an API key or subscription plan, we collect your name, email address, billing information, and company details.
  • Usage Data: We automatically collect data about your interactions with our API, including input prompts, output responses, timestamps, request volume, and performance metrics. This data is essential for routing tasks to models like GPT-5.5, Gemini 3.1 Pro, and Claude Opus 4.8, and for synthesizing outputs.
  • Technical Data: We collect IP addresses, browser type, device information, and operating system to ensure security and optimize service delivery.
  • Cookies and Tracking Technologies: We use cookies and similar technologies to enhance your experience, analyze usage patterns, and manage authentication. You can control cookie preferences through your browser settings.

2. How We Use Your Information

We use the collected information for the following purposes:

  • Service Delivery: To process your API requests, orchestrate multi-agent tasks, and return synthesized results from our model pool.
  • Improvement and Development: To analyze usage patterns, benchmark performance (e.g., SWE-Bench Pro, GPQA-Diamond), and refine our orchestration algorithms.
  • Communication: To send service updates, billing notices, and respond to inquiries at [email protected].
  • Security and Compliance: To detect and prevent unauthorized access, fraud, or abuse, and to comply with applicable laws, including GDPR for users in the EU/EEA.
  • Research: Aggregated, anonymized data may be used for internal research and publication of technical reports, as referenced in our documentation.

3. Data Sharing and Disclosure

We do not sell your personal information. We may share data under the following circumstances:

  • Third-Party Model Providers: When you use Fugu or Fugu Ultra, your input prompts are routed to publicly available frontier models (e.g., GPT-5.5, Gemini 3.1 Pro, Claude Opus 4.8) for processing. These providers have their own privacy policies, and we ensure they adhere to data protection standards.
  • Service Providers: We engage trusted third parties for cloud hosting, payment processing, and analytics, who are bound by confidentiality agreements.
  • Legal Requirements: We may disclose information if required by law, court order, or to protect our rights, property, or safety.
  • Business Transfers: In the event of a merger, acquisition, or sale of assets, your data may be transferred as part of that transaction.

4. Data Retention

We retain your personal information for as long as your account is active or as needed to provide services. Usage data, including prompts and outputs, is retained for up to 12 months for performance analysis and debugging, after which it is anonymized or deleted. Billing records are retained as required by tax and accounting laws.

5. Your Rights and Choices

Depending on your jurisdiction, you may have the following rights:

  • Access and Portability: Request a copy of your personal data in a structured format.
  • Correction: Update inaccurate or incomplete information.
  • Deletion: Request deletion of your data, subject to legal obligations.
  • Objection and Restriction: Object to or restrict certain processing activities.
  • Withdraw Consent: Where processing is based on consent, you may withdraw it at any time.

To exercise these rights, contact us at [email protected]. We will respond within 30 days. For EU/EEA users, note that our services are currently restricted in that region due to GDPR compliance; we are working to enable access.

6. Cookies Policy

We use cookies for essential functions (e.g., session management, authentication) and analytics (e.g., page views, usage trends). You can manage cookies through your browser settings. Disabling certain cookies may affect service functionality. We do not use cookies for targeted advertising.

7. Security

We implement industry-standard security measures, including encryption in transit (TLS) and at rest, access controls, and regular audits, to protect your data. However, no system is completely secure, and we cannot guarantee absolute security.

8. International Data Transfers

Your data may be processed in Japan, the United States, or other countries where our service providers operate. We ensure appropriate safeguards, such as Standard Contractual Clauses, for cross-border data transfers.

9. Children’s Privacy

Our services are not intended for individuals under the age of 16. We do not knowingly collect data from children. If you believe a child has provided us with data, please contact us.

10. Changes to This Policy

We may update this Privacy Policy periodically. Changes will be posted on this page with a revised “Last updated” date. We encourage you to review it regularly.
