Terms of Use

1. Scope

These terms set out the conditions for using the application “Fumenru” and this website (together, the “Service”) provided by MATATABI, K.K. (the “Company”). Anyone who uses the Service (a “user”) is deemed to have agreed to these terms.

If you obtained the app from the App Store, Apple’s Licensed Application End User License Agreement also applies. Where that agreement and these terms conflict, these terms prevail to the extent that agreement allows.

Personal information is handled as set out in our Privacy Policy, which forms part of these terms.

2. Registering and managing your account

The sample scores and the blank score can be used without an account. An account, which is free, is required to read a photographed score and to save scores.

• Please register accurate information.
• You are responsible for looking after your sign-in details. They may not be lent or transferred to anyone else.
• Minors should use the Service with the consent of a parent or guardian. The same applies to paid features.
• One account per person. Accounts may not be created in order to receive free allocations more than once.

3. Sheet music and copyright

Only the following may be brought into the Service. It is your responsibility to confirm that a score falls into one of these categories.

• Sheet music to which you hold the rights
• Sheet music you have permission from the rights holder to use
• Sheet music whose copyright term has expired

The Company does not supply or distribute sheet music. Results are stored only inside your own account and are never made public or shared with other users.

Rights in the score data produced by reading belong to you. The Company handles it only as far as is necessary to provide and store the Service and to investigate faults.

Reports of rights infringement are received through our Contact page. We review each report and, where necessary, delete the data concerned or suspend the account.

4. Tokens, used for reading

Reading a photographed score spends “tokens” held in your account. Playback, viewing, editing, saving and exporting do not spend tokens.

• The number of tokens a reading costs is set by the Company, per photographed page. The app shows what a reading will cost before it starts.
• The amount is deducted when the reading request is accepted. The amount spent and the amount remaining can be checked in the app.
• If a reading fails — because of load, a bad connection, or an image that could not be read as sheet music — the Company may return the deducted amount, as it determines. A reading that succeeds but contains mistakes is not eligible for a return; mistakes can be corrected in the app.
• Tokens can be used only within the Service. They cannot be exchanged for cash or transferred to another user.

There are two kinds of tokens: those the Company gives you free of charge and those issued by purchase. The app shows the remaining amount of each. When you read a score, tokens given to you free of charge are spent first.

The number of tokens required to read one page may be revised as processing costs change. The app shows the current amount before a reading starts.

5. Tokens given free of charge

The Company may give out tokens free of charge from time to time, as a promotion or as an operational adjustment. Whether tokens are given, how many, and on what conditions are determined by the Company, and may be changed or discontinued.

• Tokens given free of charge are tracked separately from tokens issued by purchase. They are not subject to the clawback that follows a refund (see below).
• They may not be received more than once by creating several accounts. Where we judge that this has happened, we may cancel the tokens concerned or suspend use of the Service.

6. Paid features and payment

Tokens can be purchased inside the app. What is on sale, and at what price, is shown on the purchase screen in the app. The sales terms are set out in the Commercial Transaction Act notice.

• Purchases are made through in-app purchase on the App Store or Google Play. Payment terms follow the rules of each store.
• Tokens are a consumable product and cannot be restored through a purchase restore.
• Refunds follow the rules of each store. The Company cannot issue refunds directly.
• If a store grants you a refund, the Company withdraws the tokens issued by that purchase from your balance. If they have already been spent, the balance of purchased tokens goes negative and is offset against your next purchase. Tokens given free of charge are not withdrawn.
• Purchased tokens do not expire. Tokens given free of charge may be given an expiry date, which will be shown in the app.
• Deleting your account forfeits all unused tokens, including those you purchased. No refund is made. Please check before deleting.

Tokens issued by purchase are a prepaid payment instrument for own-business use under Japan’s Payment Services Act. The following is disclosed under that Act.

• Issuer: MATATABI, K.K.
• Where they can be used: only for reading photographed sheet music within the Service (the “Fumenru” app)
• Expiry: none
• How to check the unused balance: the “Tokens” screen in the app shows the balance, its split between tokens given free of charge and tokens purchased, and the record of increases and decreases
• Complaints and enquiries: our Contact page, or the contact form in the app
• Points to note: no refund in cash is made (except where the Payment Services Act requires one). Tokens cannot be transferred to another person or reissued. Please look after your own sign-in details
• Terms governing use: these terms

7. Prohibited conduct

The following are prohibited when using the Service.

• Bringing in sheet music to which you hold no rights, or for which you have no permission
• Conduct that breaks the law or offends public order and morals
• Copying, altering, disassembling, decompiling or reverse engineering the Service
• Interfering with the operation of the Service, including bulk reading by automated means and placing an excessive load on the servers
• Unauthorised access, or attempting it
• Receiving free allocations more than once by using several accounts, or otherwise manipulating token balances improperly
• Lending, transferring or selling an account to a third party
• Infringing the rights or interests of other users, of third parties, or of the Company

Where these terms are breached, we may suspend use of the Service, delete the data concerned, or delete the account, without prior notice.

8. Suspension and changes to the Service

We may suspend all or part of the Service without prior notice in the following cases.

• Maintenance or updating of equipment
• A fault, or a suspension of a service we rely on
• Natural disaster or other force majeure that makes provision of the Service difficult

The Company may add to, change or discontinue features of the Service. Changes that materially affect users will be announced in advance.

If the Service is discontinued, we will give at least 30 days’ notice. Unused tokens issued by purchase will be refunded as required by Japan’s Payment Services Act; the method and the period for claiming will be announced together with the notice of discontinuation. Tokens given free of charge are not refunded.

9. Disclaimers

Reading sheet music is performed by AI recognition, and the result can contain mistakes. The Company does not warrant that the result matches the original score. What was read can be corrected in the app.

The Company does not warrant that using the Service produces any particular performance or learning outcome.

Disputes or losses arising from bringing in sheet music to which you hold no rights are yours to resolve.

Except where the Company is wilful or grossly negligent, the Company’s liability in connection with the Service is limited to ordinary damages and does not extend to damages arising from special circumstances. In any case, liability is capped at the amount the Company received from that user over the preceding 12 months.

10. Governing law and jurisdiction

These terms are governed by the laws of Japan.

Any dispute between the Company and a user in connection with the Service shall be subject to the exclusive jurisdiction of the district court having jurisdiction over the location of the Company’s head office, as the court of first instance.

11. Changes to these terms

The Company may change these terms in accordance with the law. Any change will be announced by publishing the revised text and the date it takes effect on this page.

Changes that are disadvantageous to users will be announced in advance. Using the Service on or after the effective date is deemed agreement to the revised terms.
