利用規約

These Terms of Service (these "Terms") set out the conditions between Romanark Inc. (the "Company") and every person using the Service (each a "User") for the use of "Arkor" — including the web application, the API served at api.arkor.ai, inference endpoints served at *.arkor.app, the CLI/SDK, and related services (collectively, the "Service").

Individual rules and guidelines the Company publishes within the Service form part of these Terms.

A User is deemed to have agreed to these Terms and to the Company's Privacy Policy at the earliest of: creating an account for the Service, logging in to the Service, or using the Service. Users who cannot agree to these Terms may not use the Service.

Each person (or, for corporations, each legal entity) may hold only one account. Users must not create or hold multiple accounts without the Company's prior consent. The Company may suspend or delete all or part of any accounts it reasonably determines to be held by the same User.

Users shall manage their account credentials at their own responsibility and shall not allow third parties to use them, nor lend or transfer them. Except in cases of the Company's willful misconduct or gross negligence, the Company is not liable for damage arising from inadequate credential management or use by third parties.

The Company may suspend or delete an account when a User violates these Terms.

In using the Service, Users must not:

1. violate laws or public order and morals;
2. engage in conduct related to criminal activity;
3. infringe the intellectual property, portrait, privacy, or other rights or interests of the Company or any third party;
4. place excessive load on the Service's servers or networks, gain unauthorized access, or otherwise interfere with the operation of the Service;
5. improperly use another User's account;
6. train, fine-tune, or run inference on models for the purpose of generating or distributing illegal or harmful content;
7. violate — or cause the Company to violate — the terms of service or usage policies (including Acceptable Use Policies) of the third-party cloud and other external services the Company uses to provide the Service. These external services include, in addition to those currently in use, services listed preemptively for possible future use, and include without limitation PostHog, Sentry, Amazon Web Services (AWS), Microsoft Azure, Google Cloud, Vercel, Cloudflare, SAKURA internet, Mintlify, and Modal. The Company may add to or change this list at any time; or
8. engage in any other conduct the Company reasonably deems inappropriate.

Rights in data a User uploads to or generates through the Service — including training data, trained models/adapters, prompts, and inference outputs ("User Content") — belong to the User or the rightful holder.

The Company may handle User Content to the extent necessary to provide, maintain, and improve the Service and to respond to incidents. Users represent and warrant that they hold the lawful rights necessary to upload User Content to, and have it processed by, the Service.

When using a paid plan, Users shall pay the fees separately determined by the Company and displayed within the Service, by the method the Company designates. Paid fees are non-refundable except as required by law or as separately determined by the Company.

The Company may change, suspend, or terminate all or part of the Service with prior notice to Users (or subsequent notice in urgent cases). Except in cases of the Company's willful misconduct or gross negligence, the Company is not liable for damage Users incur as a result.

The Company makes no warranty, express or implied, that the Service is free from de facto or legal defects (including defects in safety, reliability, accuracy, completeness, validity, fitness for a particular purpose, or security; errors or bugs; or infringement of rights). The same applies to the accuracy of inference results and generated outputs of the Service.

Except in cases of the Company's willful misconduct or gross negligence, the Company's liability is limited to direct and ordinary damage actually incurred by the User, and its aggregate amount shall not exceed the total fees the User paid to the Company in the 12 months preceding the event giving rise to the damage.

The Company may amend these Terms pursuant to Article 548-4 of the Civil Code of Japan. When amending these Terms, the Company will fix an effective date for the amended Terms and, a reasonable period before that date, publicize the fact of the amendment, the content of the amended Terms, and the effective date, by posting within the Service or by other appropriate means. The amended Terms apply from that effective date.

Users may not assign to any third party, or pledge as security, their contractual position under these Terms or any rights or obligations under these Terms, without the Company's prior written consent.

Even if any provision of these Terms, or part thereof, is held invalid or unenforceable under applicable law, the remaining provisions — and the remainder of any partially invalidated provision — shall continue in full force and effect.

For matters not provided for in these Terms, or when questions arise concerning their interpretation, the Company and the User shall first seek resolution through good-faith consultation.

These Terms are governed by and construed in accordance with the laws of Japan. Any dispute between the Company and a User arising in connection with the Service or these Terms shall be subject to the exclusive agreed jurisdiction of the Sapporo District Court as the court of first instance.

The Japanese version of these Terms is the authoritative text. Even where an English translation is provided for reference, the Japanese version prevails in the event of any discrepancy between the two.
