These Terms of Use ("Terms") govern your use of "KotoRoku" (the "App"), an application for iPhone and iPad provided by Masaya Sakuragi, an individual developer (the "Provider"). By using the App, you agree to these Terms.
1. These Terms apply to all matters between the Provider and the user relating to use of the App.
2. Use of the App is subject to Apple's Licensed Application End User License Agreement (the "Standard EULA"). These Terms supplement the Standard EULA.
3. If these Terms conflict with the Standard EULA, the Standard EULA prevails with respect to the conflicting part.
4. The Provider maintains a separate Privacy Policy for the App. The Privacy Policy forms part of these Terms.
1. You use the App at your own responsibility.
2. If you use a cloud AI service from the App, you must meet the age requirements and other eligibility conditions set by that AI provider. Some providers require you to be 18 years of age or older. You are responsible for checking the conditions of the provider you select.
3. If you are a minor, you may use the App only with the consent of a parent or other legal guardian.
1. The App supports recording, transcription, summarization, and minutes creation for meetings and other conversations.
2. Transcription is performed on your device using Apple's speech recognition.
3. You choose how summaries and minutes are produced: "On-device", "Local AI", or "Cloud AI". With on-device and local AI, meeting data is processed on your device. With cloud AI, meeting data is sent directly from your device to the AI provider you select.
4. The Provider does not operate any server that receives or stores meeting data.
5. The functions of the App, and the AI services and models it supports, may change without notice.
1. Recording starts only when you tap the record button. The App does not start recording automatically upon detecting sound.
2. You are responsible for notifying the participants of a meeting or conversation in advance that it is being recorded, and for obtaining any consent required.
3. You must comply with applicable laws (including personal data protection laws, laws on the secrecy of communications, employment laws, and the recording laws of each country and region) and the rules of your organization when recording, transcribing, summarizing, creating minutes, and storing or sharing them.
4. If you handle confidential information, trade secrets, personal data, or other information involving the rights of third parties, you are responsible for confirming that you have the authority to do so.
5. The Provider bears no responsibility for your recording activities or your handling of meeting data.
1. When you use a cloud AI service, the contract between you and that AI provider, and that provider's terms and policies, apply. The Provider is not a party to that contract.
2. When you use a cloud AI service, the full transcript, the meeting title, location, and participant names you entered, the speaker attribution, and any instruction text you edited are sent to that AI provider. The recorded audio file itself is not sent.
3. Retention periods, whether inputs are used for AI training, whether humans may review them, and the countries where processing occurs differ by AI provider. Review the information shown by the App before sending, and the provider's current terms and policies, before using the service.
4. Any fees for using a cloud AI service (API usage fees) are payable by you to that AI provider. The Provider does not bear them.
5. The Provider is not responsible for the content, quality, availability, pricing changes, or discontinuation of services offered by AI providers.
1. You are responsible for managing your API keys and other credentials.
2. The App stores API keys in the device keychain and uses them only to authenticate with the corresponding AI service. They are never sent to or stored on any server operated by the Provider.
3. The Provider is not liable for damages arising from use of your API key by a third party.
1. You may specify an OpenAI-compatible endpoint as a "Custom AI".
2. For destinations on the internet or otherwise outside your local network, only HTTPS connections are permitted. Unencrypted HTTP connections are permitted only for destinations that the App determines to be the device itself or within the local network.
3. Unencrypted communication may be intercepted or altered by third parties on the same network. Use this function only on networks and with destinations you trust.
4. How a custom AI handles your data is determined by the operator of that destination. The Provider does not control or guarantee it. Do not send confidential information to a destination whose data handling you cannot verify.
1. Temporary files created by the App for processing, sharing, or file creation are deleted after they have served their purpose. If deletion does not complete, it is performed at the next launch or another appropriate time.
2. Files you export to your destination folder (minutes and audio) are not deleted automatically by the App. You manage and delete them yourself as needed.
3. Recorded audio is retained in the App's private storage area on your device and is deleted automatically after one week by default. You can change the retention period in the "Info" tab. Minutes are not subject to automatic deletion and are retained until you delete them. Deleting the App from your device deletes all data in that area.
4. Retained audio can be played back from the "Info" tab, and can be transcribed again to recreate its minutes.
5. A recording you choose to discard cannot be restored.
6. The Provider does not back up your data. You are responsible for preserving any data you need.
You must not do any of the following when using the App.
1. Violate any law or public order and morals.
2. Record a conversation without the consent of third parties where such consent is required by law.
3. Infringe the rights of third parties, including copyright, portrait rights, privacy rights, and rights in trade secrets.
4. Decompile, disassemble, otherwise analyze, or modify the App, except to the extent permitted by law.

3. Rights in the audio you record, the transcripts, the information you enter, and the minutes generated belong to you or the respective rights holders. The Provider claims no rights in them.
4. The App uses open source software provided by third parties. Each is subject to the license set by its rights holder.
5. AI models used for local AI (including Qwen, Gemma, and any model you specify) are subject to the licenses and prohibited-use policies set by their respective rights holders. You must comply with those conditions. The applicable licenses are listed in the "Info" tab of the App.
1. Transcripts and AI-generated summaries and minutes may contain errors, omissions, or statements that differ from the facts.
2. You must review the generated content yourself and make any necessary corrections before relying on it.
3. The Provider makes no warranty as to the accuracy, completeness, or fitness for a particular purpose of the generated content.

2. The Provider is not liable for damages arising from any of the following.
1. Abnormal termination of the device, loss of power, insufficient storage, or other causes attributable to your device.
2. Failure, omission, or loss of recordings, transcripts, summaries, or minutes.

1. Even where the Provider is liable to you for damages, that liability is limited to direct and actual damages that ordinarily arise, and the Provider is not liable for lost profits, lost business opportunities, loss of data, or other indirect, special, or consequential damages.
2. Because the App is provided free of charge, the Provider's total liability for damages is limited to the maximum extent permitted by law.
3. If any part of this Article does not apply due to the Consumer Contract Act or other mandatory law, that part remains effective to the extent permitted.
1. The Provider may change these Terms in response to changes in law, the functions of the App, or other circumstances.
2. For significant changes, the Provider will notify users within the App or by another appropriate method.
3. The revised Terms apply from the date they are posted in the App or from another effective date specified. If you continue to use the App after a change, you are deemed to have agreed to it.
