Terms of use

The terms for using this website and our free apps.

Last updated: 30 September 2026

1. Scope

These terms apply to this website (kiyari-group.com) and to our apps Cellar Book, Recipe Book, Learn Japanese, Yuki and Gym Bot (together, the “Services”), provided by Kiyari GK (合同会社きやり, “Kiyari”, “we”). By using the Services you agree to these terms.

AI Broker (aibrokerhq.com) is governed by its own terms of service and disclaimer. Paid consulting and development work is governed by the agreement for that engagement.

2. Our apps

  • Free and as-is. The apps are provided free of charge and as they are. We may change, suspend or discontinue any app or feature at any time.
  • Your data stays with you. The apps store what you enter on your own device. Clearing your browser’s data, changing device or uninstalling an app can delete it, and we cannot restore it. Keeping backups is your responsibility.
  • Your own API keys. Some features of Cellar Book and Yuki use an AI provider (OpenAI or Anthropic) through an API key you supply. You are responsible for that key, for your agreement with the provider, and for any charges it makes. Keep the key private.
  • AI output can be wrong. Label readings, ratings, tutoring and other AI-generated content may be inaccurate or incomplete. Check anything that matters before relying on it.
  • Not professional advice. Gym Bot provides general exercise information, not medical advice. Consult a qualified professional before starting a new programme, and stop if you feel pain or discomfort. Cellar Book’s notes and ratings are for personal record-keeping.

3. Acceptable use

You agree not to misuse the Services, including by: breaking the law or infringing others’ rights; interfering with, overloading or attempting to gain unauthorised access to the Services or the systems behind them; sending spam or automated submissions through the contact form; or using the Services to harass or harm anyone.

4. Intellectual property

The Services, including their software, design, text, graphics and the Kiyari name and logo, belong to Kiyari or its licensors. You may use the apps for your own personal purposes. You may not copy, modify, redistribute or reuse them commercially without our permission, except as the law allows. What you record in the apps is yours.

5. Disclaimer

We make no warranty, express or implied, that the Services will be error-free, uninterrupted, accurate, or fit for a particular purpose, to the extent permitted by law.

6. Limitation of liability

To the extent permitted by law, Kiyari is not liable for any loss or damage arising from your use of, or inability to use, the Services, including loss of data stored on your device or charges made by a third-party AI provider. This limitation does not apply where the loss was caused by our intentional misconduct or gross negligence, or where the law, including Japan’s Consumer Contract Act (消費者契約法), does not permit it.

The Services link to, and some features rely on, services run by others. Their own terms and policies apply, and we are not responsible for their content or availability.

8. Changes to these terms

We may update these terms. The date at the top shows the latest version, and continued use of the Services after a change means you accept the updated terms.

9. Governing law and jurisdiction

These terms are governed by the laws of Japan. The Tokyo District Court (東京地方裁判所) has exclusive jurisdiction as the court of first instance for any dispute arising from them.
