Terms of Use
Last updated 21 October 2026 · the change to Your content applies from 4 November 2026
These terms apply when you use ScoreLens. Installing or using the app means you accept them. ScoreLens is provided by Dzmitry Shaidorau, an individual developer in Poland (hello@scorelens.app). If you got the app from the App Store, Apple’s Standard Licensed Application End User License Agreement also applies and these terms add to it; Apple is not a party to these terms and is not responsible for ScoreLens or its support.
The short version. Scan and share music you have the right to scan and share. Recognition is imperfect and you should check the result against the page before you rely on it. Purchases are handled by Apple and Google, and refunds go through them. We can't promise the app is error-free; our liability is limited only as far as the law allows.
What ScoreLens does
ScoreLens photographs printed sheet music and converts it into a score you can view, play back, transpose and export as MIDI, MusicXML or PDF. Recognition runs on our server and needs an internet connection.
The app works best on single-line parts — voice, wind, strings, guitar, choir and orchestra parts, method books. It reads piano too; beginner and intermediate pieces work best. It is not built for handwritten manuscript or tablature, and we do not promise usable results for those.
Recognition is not guaranteed to be correct
Optical music recognition is difficult, and ScoreLens will sometimes read a note, a rhythm or a marking wrongly, or fail on a page altogether. The app flags some problems it can detect, but the absence of a warning does not mean the result is correct.
Always check the recognised score against the printed page before you learn, perform, record, teach or publish from it. ScoreLens is a tool to save you typing, not an authority on what the music says. We are not responsible for the consequences of a mistaken recognition, including time spent learning something incorrectly.
What you may scan
You are responsible for having the right to scan and convert whatever you photograph. Most printed sheet music is protected by copyright, and the fact that you own a physical copy does not by itself give you the right to create or distribute a digital version of it.
Use ScoreLens for material that is in the public domain, that you own the rights to, that you have permission to convert, or that the law of your country permits you to copy for private study. Do not use it to produce or distribute copies you are not entitled to make. If a rights holder contacts us about material sent through the report button or shared by link, we will remove it.
Sharing a part by link
You can share the notes of a piece as a link that anyone who has it can play for 30 days. You are responsible for having the right to share what you share. Before a link is made you confirm that the music is in the public domain, is your own, or that you have permission to share it. Owning a printed copy, or being allowed to copy it for your own study, usually does not include the right to pass a digital copy to others.
Do not share anything unlawful, abusive, or that infringes someone else's rights. Anyone who opens a shared part can report it. If we receive a report or a notice from a rights holder that we believe is justified, we remove the shared notes and the link stops working; we may also stop a device from creating links. Rights holders can send notices to hello@scorelens.app with the link and the work concerned. Shared parts are recognised automatically and may contain errors; whoever opens one should check it against the printed music.
The free allowance and Pro
ScoreLens includes a limited number of free page recognitions per device within a rolling window; the current limit is shown in the app and in the store listing. The count is kept per device. On Android this survives reinstalling the app; on iOS the identifier the app uses can change when you reinstall, so in some cases the allowance may reset.
ScoreLens Pro removes that limit and unlocks export. Prices are shown in the app before purchase in your local currency. Purchases are sold and processed by Apple or Google, not by us: your contract for the payment itself is with the store, and their terms govern billing, renewal and refunds.
If Pro is sold as a subscription it renews automatically until you cancel it, which you do in your App Store or Google Play account settings rather than in the app. If it is sold as a one-time purchase it does not renew. Cancelling stops future charges; it does not refund charges already made.
Refunds are handled by the store that took your money. Ask Apple or Google through their refund process. We cannot issue a refund for a purchase we did not process, but if something is wrong with the app, write to hello@scorelens.app and we will help where we can. If you ask Apple for a refund of an in-app purchase, we may send Apple information about your use of ScoreLens (for example, how long you have used the app, how much of your purchase you used, and your past purchases and refunds) so that Apple can decide on your request. We don't send your music, photos or name.
EU right of withdrawal. Purchases are made through Apple or Google, which handle the 14-day right of withdrawal under their terms. When you ask for Pro to start immediately, the store asks you to acknowledge that the right of withdrawal ends once supply begins.
We may change Pro features for valid reasons (for example, a provider we depend on stops working). If a change takes away something important you paid for, we will tell you in advance in the app, and you may cancel and get a refund for the unused period.
Free pages, teacher codes and offer codes have no cash value, can’t be exchanged or transferred, and may be changed or ended at any time; Pro time already granted stays.
Customers in Japan: see the notice under the Act on Specified Commercial Transactions (特定商取引法に基づく表記).
Requirements
An iPhone or Android phone with a supported OS version (see the store listing), a camera or photo library, and an internet connection to recognise new pages.
Complaints
If ScoreLens doesn’t work as described, write to hello@scorelens.app with what happened and, if you can, the Support code from Settings. We reply within 14 days. If you are a consumer in the EU, you have the statutory rights for digital content and services that do not conform to the contract, including having the problem fixed or, failing that, ending the contract and, for a paid purchase, a refund through the store.
Acceptable use
- Do not attempt to break, overload or circumvent the recognition service, the free-page limit, or the purchase checks.
- Do not automate uploads or use the service other than through the app.
- Do not upload material that is unlawful where you are.
We may refuse service to a device that does these things.
The service can change or stop
ScoreLens depends on a server we run. We aim to keep it available, but we do not promise uptime, and recognition may be unavailable during maintenance or outages. We may change, suspend or discontinue the service. If we ever shut the service down permanently, we will give notice in the app or on this site where we reasonably can.
Your library lives on your device and remains readable in the app, but recognising new pages requires the service to be running.
Ending the contract
You can stop using ScoreLens at any time by deleting the app; cancel any subscription in the store first.
Your content
The photographs you take and the scores produced from them are yours. We claim no ownership of them. The exceptions are material you deliberately send through the report button, which you allow us to keep and use to improve recognition, and the notes of a part you share by link, which you allow us to store and show to anyone with the link for up to 30 days, as described in the Privacy Policy.
From 4 November 2026, when ScoreLens recognises a page you allow us to keep the recognised notation, your corrections and fingerprints of the notes, without a device identifier, for 1 year, and to use them to improve recognition, train our models and recognise the same pieces faster for everyone, as described in the Privacy Policy. This does not cover your photos, which are not used for training. Another user’s reading is only a signal to correct a reading and is never given to anyone as a copy of the piece. A rights holder can ask us to remove a work at hello@scorelens.app.
The app itself
ScoreLens, its name, design and code are ours, apart from open-source components used under their own licences. Recognition uses the open-source homr engine (AGPL-3.0), which our server runs, in a modified version whose source is published, as a separate program; see Open-source licenses.
Warranties and liability
We work to make ScoreLens reliable, but recognition is never perfect and the service may sometimes be unavailable. We are liable without limit for damage caused intentionally or by gross negligence, for injury to life or health, and wherever the law does not allow a limit. Otherwise, for slight negligence, our liability is limited to the foreseeable damage typical for this kind of app and, in total, to the amount you paid us in the 12 months before the claim.
Your statutory consumer rights, including those under Polish, EU and Japanese consumer law, are not affected by these terms and are not taken away by them.
Governing law
These terms are governed by the law of Poland. If you are a consumer, you may also rely on the mandatory consumer protections of the country where you live, and may bring proceedings there.
Changes to these terms
We may update these terms. The date at the top shows the current version, and material changes appear here before they take effect. We will tell you about material changes in the app at least 14 days before they apply. If you don’t agree, you can stop using ScoreLens and cancel your subscription.
Reports, removals and contact
Single point of contact (EU Digital Services Act, Art. 11–12) for authorities and users: hello@scorelens.app, in English, Polish or Japanese. To report a shared part, use its Report link or email us with the link, why you believe it is illegal, your name and email (not required for child-abuse reports), and a statement that you believe the report is accurate and complete. We review reports manually, without automated decisions, and remove material that is illegal or infringes someone’s rights; we may block a device that repeatedly shares such material. If we remove your shared part and know how to reach you, we tell you why, and you may contest it by replying to that email.
