Terms of Service

These Terms of Service (the "Terms") set forth the conditions for using the mobile application "KoeColor" (marketed as "VocalLens") (the "App" or "the Service"), provided by Uniikura (the "Developer"). By starting to use the App, you are deemed to have agreed to these Terms.

1. Application

These Terms apply to all users who use the App. If a minor uses the App, please obtain the consent of a parent or guardian.

2. Service Description, Non-Medical Disclaimer

2-1. Service description

The App is a voice training support tool that performs short voice recordings (up to 10 seconds), analyzes acoustic features, presents scores, and provides practice suggestions.

2-2. Non-medical and non-diagnostic (important)

• The App provides "reference information about voice quality" and "general practice suggestions"; it does not assert medical conclusions.
• If you experience pain, discomfort, hoarseness, or difficulty vocalizing in your voice, throat, or body, please stop using the App immediately and consult a medical institution such as an otolaryngology clinic.
• Voice training outcomes and improvement effects vary by individual. The Developer does not guarantee any specific effect from using the App.
• The App's scores and analysis results are reference values showing tendencies in voice quality, not absolute evaluations.

3. Prohibited Conduct

Users must not engage in any of the following:

• Reverse engineering, tampering with, unauthorized access to, or cracking of the App
• Fraudulent acquisition of advertising rewards (including unauthorized viewing via ad-skipping tools, VPNs, virtual environments, etc.)
• Generating or transmitting illegal, harmful, defamatory, or discriminatory content through the App
• Recording, analyzing, or transmitting the voices of others without their consent
• Providing commercial services based on the App without authorization
• Any other acts that violate laws, regulations, or public order and morals

4. Intellectual Property Rights

Intellectual property rights related to the App's code, design, analysis algorithms, UI design, text content, etc., belong to the Developer or the rightful rights holders. Users may use the App only for personal and non-commercial purposes.

5. Advertising and Reward Conditions

• Advertising rewards are granted only when the advertisement is viewed in full. Rewards are not granted if the user skips partway.
• Ad skipping or fraudulent acquisition of rewards via tools, scripts, or other illegitimate means is prohibited. If a violation is confirmed, use may be suspended.
• The conditions, frequency limits, and content of rewards may be changed without prior notice.
• Advertising display depends on the advertising network provider (e.g., Google AdMob) and may not always be available.
• The Developer is not responsible for the content of advertisements.

6. LLM Consultation Feature Notes

• The LLM consultation feature uses external large language model APIs (e.g., OpenAI).
• AI (LLM) responses are generated probabilistically and may contain errors, inaccurate information, or outdated information.
• AI responses are merely reference information and do not substitute for medical advice, professional opinions, or established facts.
• Final decisions must be made by the user themselves.
• When using the consultation feature, voice quality score data (compact JSON) and user question text (up to 20 characters) are sent to an external API service. Please do not include personally identifiable information, confidential information, or medical information in your questions.
• Communications and logs for the LLM feature are processed according to the terms and policies of the external service provider.

7. Suspension, Modification, and Termination of Use

• The Developer may suspend use without prior notice if a user violates these Terms.
• The Developer may change, add, remove, temporarily suspend, or terminate features of the App without prior notice.
• When the Service is terminated, we will notify users in the app or in the App Store update description to the extent possible.
• The Developer is not responsible for any damages caused by the termination of the Service.

8. Limitation of Liability and Disclaimer

• The Developer shall not be liable, to the maximum extent permitted by law, for any damages caused by ordinary negligence in connection with the use of the App. However, this limitation does not apply to damages caused by the Developer's willful misconduct or gross negligence, nor to cases where such limitation would be invalid under the Consumer Contract Act or other mandatory laws of Japan.
• The Developer is not responsible for the results of actions taken based on the App's analysis results or LLM responses (e.g., changes in voice practice methods).
• The Developer is not responsible for damages caused by failures, suspensions, malfunctions, or information leaks of external services (advertising SDKs, LLM APIs, etc.).
• Even if liability for damages is recognized, the upper limit of such compensation shall be the amount the user has paid to the App (since it is a free app, this is generally 0 yen).
• The App is provided "as is". No warranty of any kind is given regarding fitness for a particular purpose, continuous operation, or accuracy.

9. Changes to Terms

The Developer may revise these Terms. For significant changes, we will notify users in the app or in the App Store update description. If the user continues to use the App after revision, they are deemed to have agreed to the revised Terms.

10. Governing Law and Jurisdiction

These Terms are governed by and interpreted under the laws of Japan. Any disputes arising in relation to these Terms shall be subject to the Tokyo District Court as an agreed court of jurisdiction, provided that this shall not affect any jurisdiction mandatorily established under the Consumer Contract Act or other applicable laws.
