This English text is a reference translation provided for convenience. The Japanese version is the authoritative original; in the event of any discrepancy between the two, the Japanese version prevails.

These Terms of Service (the "Terms") set out the conditions for using "Shami Ittai" (the "Service"), a shamisen score digitization and practice-support service provided by Takumi Nishimura (trading as ondo) (the "Provider"). By using the Service, users (each a "User") agree to these Terms.

Article 1 (The Service)

  1. The Service provides the following features. Available features differ by plan (Free plan / Members).
  • Digitization of shamisen score images that the User owns or may lawfully use, using automated score recognition ("AI Recognition") and other technologies
  • Creation and editing of scores in the bunkafu editor
  • Practice-support features such as playback, tempo adjustment, looping, a metronome, a tuner, and audio/video recording
  • Storage of practice records and cloud synchronization across devices
  • Link-based score sharing and access to the official catalog provided by the Provider
  1. The Provider may add, change, or discontinue features. Where a change materially affects Users, the Provider will give prior notice by posting within the Service or by another appropriate means.

Article 2 (Accounts)

  1. Users may use the Service by registering an account in the manner designated by the Provider.
  2. Users must keep their registration information accurate and up to date.
  3. Users are responsible for managing their account and credentials (email address, password, third-party sign-in accounts, etc.) and must not allow third parties to use, lend, or transfer them.
  4. Users must generally be 15 years of age or older. Minors must obtain the consent of a parent or legal guardian, and must always obtain such consent before subscribing to a paid plan.

Article 3 (Fees, Automatic Renewal)

  1. Plans. The Service offers a Free plan and a paid "Members" plan. Members costs JPY 500 (tax included) per month or JPY 5,000 (tax included) per year. Free AI Recognition allowances differ as follows:
  • Using the Service without registering an account (trial use): up to 3 times in total, for the lifetime of that use (the allowance does not reset monthly)
  • Registered accounts on the Free plan: up to 3 times per month (the allowance resets each calendar month)

Limits also apply to the number of scores that can be stored. Details of the features and limits of each plan are shown on the pricing page within the Service.

  1. Costs other than fees. Communication charges and device costs required to use the Service are borne by the User.
  2. When billing starts. Members does not offer a free trial period. The fee for the selected plan (JPY 500 tax included for monthly, JPY 5,000 tax included for annual) is charged at the time the subscription process is completed. Users who wish to try the Service before subscribing may use the Free plan described in paragraph 1.
  3. Automatic renewal. Unless cancelled, a paid plan renews automatically for the same plan at the end of each billing period (one month for monthly, one year for annual), and the then-current fee is charged on each renewal. Charge timing and amounts are as stated by the applicable store or payment provider set out in the following paragraph.
  4. Payment channels. Charges are processed according to the channel through which the User subscribed:
  • iOS app: in-app purchase through the App Store operated by Apple Inc. (billed to the Apple ID)
  • Android app: in-app purchase through Google Play operated by Google LLC (billed to the Google account)
  • Web: credit card. Depending on when and how the User subscribed, the payment provider is either Web Billing provided by RevenueCat, Inc. or Stripe, Inc. (the provider applicable to a given subscription can be confirmed on the management page opened from "Billing" in the settings screen). In either case, card details are collected and processed by that payment provider and its payment processors, and are not collected or retained by the Provider.
  1. The Provider may revise fees. Any revision will be notified in accordance with Article 11 a reasonable period before it takes effect. A revision does not affect a billing period that has already begun and applies from the next renewal.

Article 4 (Cancellation and Refunds)

  1. How to cancel. Users may cancel at any time, using the method that corresponds to the channel of subscription:
  • Subscribed via the iOS app: cancel from the subscription management screen in the iOS Settings app.
  • Subscribed via the Android app: cancel from the "Subscriptions" screen in the Google Play app.
  • Subscribed via the web: open the payment provider's management page from "Billing" in the Service settings screen and cancel there. Depending on the state of the subscription, the management page may not open automatically; in that case, please contact the support address shown in the same "Billing" section, or the email address in Article 13, and the Provider will process the cancellation.
  1. Deleting the app does not cancel the subscription. Removing the app from a device, or simply ceasing to use the account, does not stop automatic renewal. Users must cancel using the methods above.
  2. Effect of cancellation. Upon cancellation, the paid plan ends at the conclusion of the current billing period, and paid features remain available until then.
  3. Refunds. Fees for the current period are not refunded and are not prorated when a User cancels mid-period, because the plan remains usable until the end of that period.
  4. The Provider cannot process refunds for in-app purchases. Refunds for payments made through the App Store or Google Play are determined and processed by Apple or Google under their own refund policies and procedures. The Provider has no authority to issue such refunds. Please contact the relevant store directly.
  5. Web payments. For payments made through the web, the Provider or its payment provider will respond. Notwithstanding the two preceding paragraphs, the Provider will issue refunds or other reasonable remedies for billing errors attributable to the Provider, such as duplicate charges caused by a system failure. Please contact the address in Article 13 first.
  6. Nothing in this Article limits any statutory right of termination or refund available to Users.

Article 5 (Rights in and Responsibility for User Content)

  1. Copyright and other rights in score images, score data, audio and video recordings, annotations, and other content that a User uploads to or creates within the Service ("User Content") belong to the User or the rightful rights holder. The Provider acquires no rights in User Content.
  2. Users represent and warrant that, for all User Content, either:
  • the User holds the copyright and all other necessary rights; or
  • the User has permission from the rights holder, the term of copyright protection has expired, or the User otherwise has a lawful basis for using the content within the Service.
  1. Users must not upload, copy, share, publish, or redistribute a third party's copyrighted work (such as commercially published method books or sheet music, or scores created by others) without the rights holder's permission or another lawful basis.
  2. The sharing feature is intended for content the User owns or may lawfully share. For copyright reasons, the Provider prevents scores produced from photo/PDF import (AI Recognition) or from audio/video transcription from being shared. Sharing also requires a registered account and is unavailable in unregistered trial use. Users must not attempt to circumvent these restrictions. The official catalog within the Service is curated and published by the Provider; it is not a feature through which Users submit their own scores.
  3. The Provider copies, stores, converts, and displays User Content only to the extent necessary to provide, maintain, and improve the Service (storage, AI Recognition and other technical processing, format conversion, cross-device synchronization, display, and the like), and will not use User Content beyond that purpose. Transmission to external services is governed by the Privacy Policy.
  4. If a dispute with a third party arises in connection with User Content, the User shall resolve it at their own cost and responsibility. If a rights holder or other third party brings a claim against the Provider, the User shall compensate the Provider for the resulting loss (including reasonable attorneys' fees) to the extent attributable to the User.

Article 6 (Accuracy of AI Recognition)

  1. AI Recognition automatically interprets and digitizes score images. Its accuracy and completeness are not guaranteed, and misrecognition may occur depending on the condition of the original, the notation style, shooting conditions, and image quality.
  2. The Provider endeavors to indicate parts that require review and to provide correction tools. Users are responsible for reviewing results before relying on them.
  3. Credits consumed by AI Recognition are not returned on the ground of recognition accuracy. However, if processing did not complete due to a system failure on the Provider's side, the Provider will restore the credits at its own cost upon contact via Article 13.

Article 7 (Prohibited Conduct)

Users must not:

  1. Upload, copy, convert, publish, share, or redistribute scores, musical works, or recordings in which a third party holds rights, without the rights holder's permission or another lawful basis;
  2. Act in violation of law or public order and morals;
  3. Infringe the copyright, trademark, image rights, privacy, or other rights or interests of the Provider or third parties;
  4. Interfere with the operation of the Service, impose excessive load on its servers, gain unauthorized access, analyze, modify, or reverse engineer the Service, or misuse it through automated means;
  5. Circumvent the credit system or other usage limits, including by creating multiple accounts;
  6. Commercially redistribute or resell data obtained through the Service without the Provider's permission; or
  7. Engage in other conduct comparable to the above that the Provider, on reasonable grounds, determines to be inappropriate.

Article 8 (Suspension and Account Deletion)

  1. The Provider may suspend a User's use of the Service, or terminate the contract and delete the account, where the User:
  • violates the prohibited conduct in the preceding Article;
  • is found to have provided false registration information;
  • fails to pay fees;
  • breaches these Terms and fails to cure the breach after the Provider has requested cure within a reasonable period; or
  • has caused, or is highly likely to cause, damage to the Provider or other Users such that immediate action is required.
  1. The Provider will endeavor to give prior notice of the reasons for any such measure. Where the fifth item above applies, or in other urgent cases, notice will be given without delay after the measure is taken.
  2. A User who objects to a measure may request an explanation via the contact in Article 13, and the Provider will respond in good faith.
  3. Where a measure is not attributable to the User, the Provider will refund the fee corresponding to the unused portion of the period.

Article 9 (Interruption, Modification, and Termination of the Service)

  1. The Provider may interrupt all or part of the Service for maintenance, failures, natural disasters, or other unavoidable reasons. Except in urgent cases, the Provider will endeavor to give advance notice.
  2. The Provider may discontinue all or part of the Service after giving at least 90 days' advance notice. In that case, the Provider will refund the fee corresponding to the unused period after the discontinuation date by a reasonable method appropriate to the User's subscription channel. For charges made through the App Store or Google Play, the User may need to request the refund from the relevant store.
  3. The Provider will endeavor to provide a reasonable period and means for Users to export their data before discontinuation.

Article 10 (Disclaimer and Limitation of Liability)

  1. The Provider does not warrant that the Service is fit for any particular purpose, that it will produce the results a User expects, or that it will be free from interruption, error, or data loss. Users are encouraged to keep their own backups of important data.
  2. The Provider is liable for loss caused to Users by its breach of contract or tort. However, where the loss is caused by the Provider's negligence (other than gross negligence), the Provider's liability is capped at the total fees paid by the User to the Provider for the Service during the 12 months preceding the occurrence of the loss, and is limited to ordinary damages.
  3. The limitation in the preceding paragraph does not apply where the Provider has acted with intent or gross negligence.
  4. The Provider is not a party to, and bears no responsibility for, disputes arising between a User and other Users or third parties.
  5. If any provision of these Terms, in whole or in part, is held invalid or unenforceable under the Consumer Contract Act or other law, the remainder of that provision and the other provisions remain in effect, and the Provider bears liability for the invalidated part to the extent permitted by law.

Article 11 (Changes to These Terms)

  1. Pursuant to Article 548-4 of the Civil Code of Japan, the Provider may amend these Terms without the individual consent of Users where:
  • the amendment conforms to the general interest of Users; or
  • the amendment does not conflict with the purpose of the contract and is reasonable in light of the necessity for the amendment, the appropriateness of the amended content, and the surrounding circumstances.
  1. When making such an amendment, the Provider will notify Users of the amended Terms, the reasons for the amendment, and the date it takes effect, by posting within the Service, by in-app notification, or by email to the registered address, before the effective date.
  2. Notice will in principle be given at least 15 days before the effective date. However, for amendments that are disadvantageous to Users, such as fee increases or material reductions in features, notice will be given at least 30 days before the effective date, so that Users have an opportunity to cancel before then.
  3. Users who do not agree to an amendment may cancel by the methods in Article 4 before the effective date. A User who uses the Service on or after the effective date is deemed to have agreed to the amended Terms.
  4. Corrections of typographical errors, reordering of provisions, and other changes that do not materially affect Users' rights or obligations may be made by posting within the Service alone.

Article 12 (Governing Law and Jurisdiction)

  1. These Terms and use of the Service are governed by the laws of Japan.
  2. Any dispute arising between the Provider and a User in relation to the Service shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance. This does not limit any right a consumer has under applicable law to bring an action in a court having jurisdiction over the consumer's place of residence.
