利用規約 Terms of Service

These Terms of Service set forth the conditions between Keiichi Washio (trade name: Overtone, the "Operator") who operates Overtone (the "Service") and users regarding the use of the Service. By using the Service, users are deemed to have agreed to these Terms.

The Service is a web-based real-time voice translation tool. Audio from web conferencing tools such as Microsoft Teams, Zoom, and Google Meet is translated and displayed in real time using AI.

The Service is an independent web application, not an officially provided add-on or integration of the above conferencing tools. The conference tool names are referenced solely for identification purposes.

• Users wishing to use the Service shall register an account using the method designated by us.
• If false information is found in the registration, we may refuse or suspend use.
• One individual may not hold multiple accounts.

4-1. Plans

We offer three plans: Starter / Standard / Premium. Monthly fees and usage limits are as displayed on the service website.

4-2. Free Trial

• The free trial lasts 7 days or up to 240 minutes of usage, whichever comes first.
• Credit card registration is required to start the trial.
• During the trial, users may access functionality equivalent to the Starter plan.
• After the trial ends, the account automatically transitions to the paid Starter plan.
• Users may cancel anytime during the trial. Cancellation prevents transition to a paid plan.

4-3. Payment

Payment is made via credit card through Stripe. This is a recurring subscription with automatic monthly renewal.

4-4. Usage Limits

If the monthly usage limit is exceeded, translation functionality becomes unavailable for that month. The limit resets on the 1st of the following month. Plan upgrades are available at any time.

Users may cancel anytime via the account settings screen. Cancellation takes effect at the end of the month in which cancellation is requested (no pro-rated refunds). The Service remains usable until the end of the month after cancellation.

In using the Service, users may not:

• Engage in conduct that violates laws or public order and morals
• Infringe intellectual property rights, portrait rights, privacy, or other rights of third parties
• Defame or harass us, other users, or third parties
• Impose excessive load on the Service's servers or network
• Reverse engineer or develop similar services imitating the Service
• Resell the Service for commercial purposes without our prior consent
• Lend, transfer, or share accounts
• Engage in any other conduct deemed inappropriate by us

1. The Service provides AI-based automatic translation. The Operator does not warrant the accuracy, completeness, or fitness for a particular purpose of the translation results.

2. Where damages arise to a user from use of the Service, except in cases of the Operator's willful misconduct or gross negligence, the Operator's liability shall be limited to ordinary and direct damages actually incurred, with a cap as follows. The limitation in this paragraph applies only to non-performance of obligations or tortious acts caused by the Operator's ordinary (slight) negligence.

(1) For paid plan subscribers: the aggregate amount of fees actually paid by the user to the Operator for the Service during the one (1) month period immediately preceding the occurrence of the damages.

(2) For users during the free trial period, or where the amount in (1) is less than JPY 1,000: JPY 1,000.

3. The limitation in the preceding paragraph does not apply in cases of the Operator's willful misconduct or gross negligence.

4. The Service is provided using third-party conferencing services such as Microsoft Teams, Zoom, and Google Meet, as well as speech recognition APIs, text-to-speech APIs, large language models (LLMs) and other external AI services. The Operator is not liable for issues arising from the operational status, changes in specifications, suspension, or failures of such external services.

5. The Operator is not liable for service interruptions due to scheduled or emergency maintenance, or external factors.

8-1. Intellectual Property

All intellectual property rights relating to the Service (software, design, logos, trademarks, content, etc.) belong to the Operator or the rightful owners. Users may not reproduce, modify, or redistribute these beyond the scope necessary for using the Service.

Translation results may be freely used by the user.

8-2. Handling of Input Data (Zero Data Retention)

The Operator handles meeting audio data and its translation text acquired through use of the Service (collectively, "Meeting Data") under the following policy (the "Zero Data Retention Policy"):

• Meeting Data is held only temporarily in memory, solely for the purpose of real-time translation processing.
• Meeting Data is immediately discarded from the Operator's systems upon termination of the relevant meeting session. The Operator does not retain Meeting Data persistently.
• The Operator does not use Meeting Data for the purpose of training AI models, and has ensured by contract or API configuration that outsourcees (Soniox, Anthropic, Google, etc.) likewise do not use Meeting Data for AI training purposes.
• Only where the user uses the meeting-minutes feature and explicitly directs the Operator to save translation text or minutes files, such files will be retained for the period specified by the user.

For details, please refer to the separately provided Privacy Policy.

We may amend these Terms as necessary. For material changes, advance notice will be provided via in-service notification or email. Amended Terms take effect on the effective date specified in the notice.

1. These Terms shall be governed by and construed in accordance with the laws of Japan.

2. Any dispute related to the Service between the Operator and a user shall be subject to the exclusive jurisdiction of the district court or summary court having jurisdiction over the Operator's principal place of business as the court of first instance.

3. However, where the user qualifies as a "consumer" under the Consumer Contract Act of Japan, notwithstanding the preceding paragraph, the user may bring an action in the court having jurisdiction over their domicile in accordance with the Code of Civil Procedure and other applicable laws of Japan.

1. Where the Operator transfers the business relating to the Service to another entity (including any company newly established by the Operator; the same applies below; whether by way of business transfer, merger, corporate split, succession of business or any other event), the Operator may transfer to such transferee the contractual status under these Terms, the rights and obligations under these Terms, and the user's registration information and personal data. The user agrees to such transfer in advance by this paragraph.

2. When a business transfer or merger occurs under the preceding paragraph, the Operator will notify users in advance by reasonable means (in-service notification, email, or posting on the Operator's website). If a user does not agree to such transfer, the user may cancel the Service.
