Article 1 (Applicability of the Terms)

1. The Terms apply to all relationships between Users and the Operations Team regarding the use of the Service.
2. The Operations Team may establish additional terms of use (hereinafter referred to as “Individual Provisions”) in addition to the Terms. Regardless of their name, such Individual Provisions shall constitute part of the Terms.
3. If there is any discrepancy between the Individual Provisions and the Terms, the Individual Provisions shall prevail unless otherwise specified.
4. Copyright in all data and other content belongs to the respective authors. If the terms of an author conflict with the Terms, the author’s terms shall prevail.

Users must not engage in any of the following acts when using the Service:

1. Acts that interfere with, or attempt to interfere with, the operation of the Service, KuronekoServer (hereinafter referred to as “the Organization”), or services provided by third parties, via the facilities of the Service.
2. Acts that may result in the global IP address allocated for IP communications being registered on blacklists, or acts that may harm the Organization’s reputation or credit, or acts that may lead to such outcomes.
3. Acts that impose unnecessary load (whether intentional or negligent) on the Organization’s facilities (network/server facilities, etc.), thereby impairing service quality or the ability of upstream providers to provide their services.
4. Infringing our rights or those of others in a way subject to lawful disclosure of sender information.
5. Acts that exhaust resources due to unauthorized traffic (communications) from external or internal sources, thereby obstructing normal traffic of Users, etc.

10. Acts that involve any interaction or involvement with anti-social forces (such as organized crime groups, members of such groups, right-wing groups, anti-social forces, or any equivalent), including cooperating with or participating in their maintenance, operation, or management.
11. Reselling the Service without prior permission from the Organization.
12. Illegally using or abusing bugs, defects, vulnerabilities, etc. against the Organization.

Article 3 (Restrictions, etc.)

We may restrict or suspend use where necessary to protect the Service or users from violations, excessive load or misuse. We normally explain the reason and how to resolve it, but may act without advance notice in emergencies. Users may request an explanation or review at support[at]krnk.org (replace [at] with @). Liability is governed by Article 10.

1. If communications increase excessively, the Organization may restrict communications or block access.
2. If the User uses the API without permission to interfere with, access, delete, or modify anything outside designated directories, the Organization will immediately suspend or restrict use.

Article 4 (Suspension of use)

We may suspend use or terminate a contract for reasonable grounds such as serious violations, unlawful conduct or misuse. Where correction is possible, we normally give reasons and a deadline to resolve the issue. Suspension from another service does not automatically suspend this Service; we assess its impact here. Urgent security needs or legal requirements may require immediate action.

Article 5 (Preservation of Communication Logs)

We may preserve necessary communication records under law or a lawful preservation request. Preservation does not remove protection of communication secrecy or other legal safeguards. Disclosure requires a lawful basis and is limited to what is necessary.

Article 6 (Commencement of Use and Usage Restrictions)

Read these Terms and the in-service guidance before using the Service. Minors must obtain guardian consent and complete any other procedures required by law.

Article 7 (Termination or Suspension of the Service)

The Service may be terminated or temporarily suspended for any of the following reasons:

1. When maintenance, inspection, or repairs of facilities required to provide the Service are performed.
2. When server hardware maintenance work is performed.
3. When program update work is performed.
4. When server hardware or programs stop due to accidents, crashes, etc.
5. When it becomes difficult to continue operating the Service due to unforeseen events such as earthquakes, lightning strikes, or heavy rain.
6. Any other case where the Operations Team determines it is difficult to continue operating the Service.

Article 8 (Changes to the Service)

Planned changes, suspension or termination will be announced on the official website or through other appropriate means, with reasonable notice reflecting their impact. If an incident or urgent security need prevents advance notice, we will inform users afterwards where possible. Any payment settlement or refund follows contract terms and applicable law.

Article 9 (Reporting Contact)

1. Report unlawful or inappropriate content to abuse@krnk.org, including:

   • Your name and contact email address
   • For copyright complaints, evidence that you are the rights holder or an authorized representative

2. For vulnerabilities, see the dedicated reporting page.

3. We normally review and respond to reports within 24 hours.

Article 10 (Disclaimer)

1. We do not guarantee continuous availability, freedom from errors, suitability for a particular purpose or permanent data storage. Keep your own copies of necessary data.
2. Where we bear legal responsibility, we respond under applicable law. We do not exclude or limit liability for intentional misconduct, gross negligence or any liability that law does not permit us to exclude or limit.
3. Users normally resolve disputes with each other or third parties themselves. This does not exclude any legal responsibility we bear.

Article 11 (Changes to the Terms)

Changes to these Terms follow the Civil Code and other applicable law. We announce the changes and effective date in advance on the official website or by other appropriate means. Where individual consent is legally required, we obtain it separately.

Article 12 (Handling of Data)

The Privacy Policy for this Service explains the information we handle, its purposes, retention, disclosure and requests for access or deletion. Disclosure to public authorities also requires a lawful basis and is limited to what is necessary.

Article 13 (Governing Law and Jurisdiction)

Japanese law governs these Terms. The Saga District Court is the agreed court of first instance for disputes about the Service, without limiting other jurisdiction or consumer rights recognized by law.
