1. Acceptance of Terms

By creating an account with or otherwise using Kagura Memory Cloud ("the Service", "we", "our", "us"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the Service.

Eligibility. You must be at least 16 years old to use the Service. Where your local law sets a higher threshold for contract capacity or data-processing consent, you must meet that threshold. By using the Service, you represent that you meet the applicable requirement.

Account. You are responsible for maintaining the confidentiality of your account credentials and for every action taken under your account. Notify us promptly if you suspect unauthorized access.

2. Access & Signup Gating

The operator of a Kagura Memory Cloud deployment may enable an admin-configurable signup gate that restricts new registrations to an allowlist. When the gate is enabled on the hosted deployment (memory.kagura-ai.com):

Registration from a provider account not on the allowlist is refused; you are redirected to a page explaining the restriction.
Existing accounts continue to work normally.
The allowlist is managed on the immutable numeric provider user ID (for example, github_user_id), so renaming your GitHub handle does not affect your access.

The self-hosted open-source edition of Kagura Memory Cloud preserves its existing behavior by default (the gate is off); the operator of any self-hosted instance may enable or configure it at their discretion.

3. Sponsorship as Purchase of Service Access

One of the ways to be added to the signup allowlist on the hosted deployment is through GitHub Sponsors. For tax, consumer-protection, and data-protection clarity, sponsorships that unlock service access are offered and accepted on the following basis:

The sponsorship is a purchase of service access, not a gratuitous donation. You pay a periodic amount and, in exchange, are granted the right to register for and use the Service at the tier corresponding to your sponsorship amount.
Service access is provided only to the natural person identified by the sponsoring GitHub account. It is not transferable.
If your sponsorship is cancelled or reduced below the minimum tier, access enters a grace period as configured by the operator (currently 30 days) and is then revoked.
Refunds follow GitHub Sponsors' policy and the consumer-protection laws applicable to you. We do not pro-rate partial months.

This section applies only to the hosted deployment. Self-hosted operators may configure any payment or invitation model they choose.

4. Service Description

Kagura Memory Cloud provides:

Memory storage — a platform for storing, organizing, and retrieving AI conversation memories and knowledge.

Multi-platform integration — access via the Model Context Protocol (MCP) and a REST API, usable from Claude, ChatGPT, Cursor, Gemini, and other MCP-compatible clients.

Team collaboration — workspaces with role-based access control (owner / admin / member / viewer) and per-context permissions.

API access — programmatic access to your memory data.

5. User Responsibilities

Lawful use. Use the Service only for lawful purposes and in compliance with applicable laws.

No abuse. Do not attempt to disrupt, overload, or compromise the Service infrastructure; do not circumvent rate limits, quotas, or access controls.

No harmful content. Do not use the Service to store or distribute spam, malware, child sexual abuse material, content inciting violence, or other material prohibited by applicable law.

No other person's data without a basis. If you store personal data about third parties, you are responsible for having a lawful basis to do so (consent, contract, etc.) and for responding to those individuals' rights requests.

Account security. Keep your credentials confidential; enable MFA where offered; notify us of suspected unauthorized access.

6. Data & Privacy

Please refer to our Privacy Policy for how we handle your data. Highlights:

Your content is yours. You retain ownership of all memories, contexts, tags, and metadata you store in the Service. You grant us only the processing license needed to operate the Service on your behalf.

We do not train on your content. We do not use the contents of your memories to train AI models.

You can export and delete. You can export your memory contents and request account deletion at any time.

7. Subscription & Billing

Free tier. The Service offers a free tier with defined usage limits; no payment information is required.

Paid / sponsored tiers. Paid access (including sponsorship-backed access as defined in Section 3) provides higher quotas and additional features. Current pricing and tier thresholds are published on the website or on request.

Cancellation. You may cancel your paid subscription or sponsorship at any time. Access continues to the end of the paid period; we do not pro-rate partial-period refunds.

Quota changes. We may adjust plan quotas with at least 30 days' advance notice.

8. Intellectual Property

The Service software. The Kagura Memory Cloud open-source codebase is licensed under its public license (see the source repository). The name "Kagura Memory Cloud", the logo, and associated trademarks remain the property of the provider.

Your content. You retain all rights to the content you store. You grant us a worldwide, non-exclusive, royalty-free license to host, copy, transmit, display, and process your content solely to the extent necessary to provide the Service to you and to honor your requests (for example, search, export, sharing you explicitly set up).

9. Limitations of Liability

Service availability. We strive for high availability but do not guarantee uninterrupted or error-free service. Scheduled maintenance will be announced in advance where reasonably possible.

No warranty. The Service is provided "as is" and "as available" without warranties of any kind, express or implied, to the fullest extent permitted by law.

Liability cap. To the fullest extent permitted by law, our aggregate liability to you for any claim arising out of or relating to the Service is limited to the amount you paid us in the 12 months preceding the event giving rise to the claim, or JPY 10,000, whichever is greater.

Consumer rights. Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable consumer-protection law (for example, for gross negligence, wilful misconduct, or for loss of life or personal injury). EU / UK residents retain their statutory rights.

Data loss. Although we maintain encrypted backups, we are not liable for loss of content under our "as is" basis. We recommend you keep your own backup for anything you cannot afford to lose.

10. Termination

By you. You may delete your account at any time from account settings or by contacting us.

By us. We may suspend or terminate your access for violation of these Terms, for non-payment of a paid tier, or where required by law. Where possible we will give prior notice and an opportunity to cure.

Effect. On termination your access ceases and your personal data is deleted on the schedule described in the Privacy Policy (except where we are legally required to retain it, e.g. tax records).

Survival. Sections 8 (Intellectual Property), 9 (Limitations of Liability), 11 (Governing Law), and any obligations that by their nature should survive, continue after termination.

11. Governing Law & Jurisdiction

These Terms are governed by the laws of Japan. The Tokyo District Court shall have exclusive jurisdiction as the court of first instance for any dispute arising out of or relating to these Terms.

EU / UK residents. Nothing in this section deprives you of the protection of the mandatory consumer-protection laws of your country of residence.

12. Changes

We may update these Terms from time to time. When we do we update the "Last updated" date at the top of the page. Material changes will be announced in-product and (where appropriate) by email. Continued use of the Service after the effective date of a change constitutes acceptance of the new Terms. If you do not accept a material change, you may delete your account before the effective date.
