Terms of Service

1. Scope

These terms apply to all use of sepiace, including the MCP server at hi.sepiace.io and this website. By using sepiace, you agree to these terms.

In these terms, the operator means Arata Ouchi, doing business as Original SIN Architecture, and you means anyone who uses sepiace.

The Privacy Policy and the Pricing page also apply to your use of sepiace.

These terms are written in English and Japanese. If the two versions differ, the Japanese version prevails.

2. Beta

sepiace is provided as a beta. Its features, specifications, usage limits, and fees may change as the service develops.

Whenever possible, the operator announces important changes on this website or by email before they take effect.

3. Accounts

• You create an account and sign in with your email address. Use an email address that you own and can receive mail at.
• An account is for one person. Do not share your account or let others use it.
• You are responsible for managing your email and the MCP clients you connect. Anything a connected client or agent sends to sepiace is treated as sent by you.
• If you suspect that someone else is using your account, contact the operator promptly.
• You can contact the operator at any time through the contact below to close your account or to request full deletion of your memories. Deleting your account when you close it does not delete your memories. To have them deleted, request full deletion.

4. Fees

Fees and usage limits follow the Pricing page. If you use a paid plan, you pay the fees shown there.

• When you sign up, you can use the Personal plan, including its 1,000 credits, free of charge for 30 days. No payment details are needed for this free month.
• The plan is billed monthly in advance and renews automatically every month until you cancel. If you subscribe during the free month, billing starts when the free month ends. Purchased credits are paid for once when you buy them.
• The Personal plan comes with 1,000 credits each billing period, and each request and the daily tidy-up use credits by what they cost to process. Monthly credits do not carry over to the next period. You can buy more credits, which do not expire and are used after your monthly credits. Purchased credits can be used only while you have a plan or your free month. When your credits are almost used up, sepiace stops saving but still looks up and forgets, and when they are used up, sepiace stops processing requests until your credits renew or you buy more.
• If the free month ends or the plan ends without a new subscription, sepiace stops processing requests until you subscribe. Your memories and any purchased credits are kept.
• You can cancel a plan at any time from the console. The plan stays available until the end of the billing period you have paid for.
• Payments are processed by Stripe. The operator does not receive or store your full card details.

The operator announces fee changes on this website before they take effect.

Fees already paid are not refunded, except where required by law or stated on the Pricing page.

5. Prohibited conduct

When using sepiace, you must not do any of the following.

• Violate laws or public order and morals.
• Infringe the rights of others, including intellectual property rights, privacy, and reputation.
• Store other people’s personal information without a lawful basis.
• Access, or try to access, other users’ accounts or memories.
• Place an excessive load on the service, or get around its rate limits or usage limits.
• Interfere with the operation of the service, such as by sending malware or probing for vulnerabilities without the operator’s permission.
• Resell sepiace, or provide it to third parties as a service, without the operator’s permission.
• Create accounts in bulk by automated means, or impersonate others.
• Any other conduct that the operator reasonably judges to be similar to the above.

6. Your data

• The requests you send and the memories stored from them belong to you. The operator does not acquire any rights to them.
• You allow the operator to store and process your data, and to send it to the external services described in the Privacy Policy, only as far as needed to provide and maintain sepiace and to train and evaluate the sepiace judgment network.
• The operator may use your memories and records of how requests were handled, including memories you asked sepiace to forget and memories of closed accounts, to train and evaluate the sepiace judgment network, which decides whether to store, recall, or forget. These records contain the text of your requests, the memories passed to the judgment, the operations chosen, and the responses returned. Training and evaluation run on the operator’s own systems, and no data is provided to third parties for them. The operator does not use your data to train any other machine learning models.
• You guarantee that you have the right to send the data you send to sepiace.
• Memories you asked sepiace to forget, memories of closed accounts, and the processing record of each request are kept until you request full deletion, as described in the Privacy Policy. When you request full deletion, the operator deletes your data as described in the Privacy Policy.

7. Changes to and suspension of the service

• The operator may change, add, or remove features of sepiace.
• The operator may suspend all or part of sepiace without notice for maintenance, failures, outages of external services such as Cloudflare or OpenRouter, disasters, or other unavoidable reasons.
• The operator may end sepiace. In that case, the operator announces it on this website or by email, with a reasonable period of notice.
• If you violate these terms, the operator may suspend your use of sepiace or delete your account.

8. Disclaimer and limitation of liability

• sepiace is provided as is. The operator does not guarantee that it is free of errors, that it is always available, or that it fits your particular purpose.
• sepiace decides automatically what to save, recall, and forget. It may fail to save something, save something you did not intend, or forget something you wanted to keep. Memories that go unused become harder to recall. Do not rely on sepiace as the only place you keep important information.
• Decisions and actions your agent takes based on memories are your responsibility.
• If the operator is liable to you for damage arising from sepiace, the liability is limited to direct and ordinary damage, up to the total fees you paid the operator in the 12 months before the damage occurred.
• This limit does not apply to damage caused by the operator’s intent or gross negligence, or where the law does not allow it.

9. Changes to these terms

The operator may change these terms when the change is in the general interest of users, or when it is reasonable in light of the purpose of these terms and the circumstances of the change.

Before a change takes effect, the operator posts the new terms and their effective date on this website. If you keep using sepiace after that date, you are treated as having agreed to the new terms.

10. Governing law and jurisdiction

These terms are governed by the laws of Japan.

The district court with jurisdiction over the operator’s location has exclusive jurisdiction as the court of first instance over any dispute relating to sepiace.
