2. Accounts

You must provide accurate registration information and keep your credentials confidential. You are responsible for activity under your account. Accounts are personal: access purchased on your account is for you and may not be shared, resold, or transferred. You must be legally able to enter into this agreement, or have a parent or guardian’s consent, to use paid features.

Sign-up is available to users aged 14 or older. Users under 14 may use the Service through an account created and managed by their parent or legal guardian. Purchases, refunds, consent to these Terms, and email preferences on such an account are managed by the guardian who owns it, and sheet music purchased by a guardian may be used by the minor children in the guardian’s care for non-commercial personal learning. We do not offer direct sign-up for children under 14.

회원가입은 만 14세 이상만 가능합니다. 만 14세 미만 이용자는 부모 또는 법정대리인이 생성하고 관리하는 계정을 통해 서비스를 이용할 수 있습니다. 해당 계정의 구매, 환불, 약관 동의 및 이메일 수신 설정은 계정 소유자인 보호자가 관리합니다. 보호자가 구매한 악보는 보호자가 관리하는 미성년 자녀의 비상업적 개인 학습 용도로 이용할 수 있습니다. 만 14세 미만 아동의 직접 회원가입은 제공하지 않습니다.

3. Digital products

Our products are digital: sheet music readable in the online Viewer (and printable for personal use) with a PDF download during the sheet’s access window, in-app song access in the Try Piano app, and online course content. Access is delivered to your account — nothing is shipped.

Downloaded PDF files are issued per account and carry buyer-identification information (a masked account identifier and a license reference) in the page margins, in a license notice page, and in the file metadata, so that a leaked copy can be traced to the purchasing account.

다운로드한 PDF 파일은 계정별로 발급되며, 여백·라이선스 고지 쪽·파일 메타데이터에 구매자 식별 정보(마스킹된 계정 식별자와 라이선스 참조값)가 포함됩니다. 유출된 사본은 구매 계정으로 확인될 수 있습니다.

4. Individual sheet purchases

An individual sheet purchase is a one-time payment that unlocks that specific sheet on your account for 180 days from the time of payment. During those 180 days it grants Viewer and print access for personal use and a PDF download of the sheet. A purchase of one sheet does not unlock any other sheet, Music Pass, or Academy.

Saving the PDF within the 180 days is your responsibility. When the window ends normally, the file you downloaded remains yours to keep for personal, non-commercial use — only new downloads, Viewer access and printing on this site stop — and the same sheet can be purchased again. If an order is refunded, the license granted by that order ends together with the account’s access (see the Refund Policy); we do not delete files from your devices, but a refunded order no longer licenses their use. Full sheet access on this site starts after you confirm the first-access notice. Starting to view does not remove your right to request a refund — refunds, including the 14-day refund-request window for Paddle-processed payments, are governed by the Refund Policyand applicable law. Before purchasing, customers can use the free sheet-music Viewer and each sheet’s free preview to confirm that the Viewer works correctly on their device and browser.

개별 악보 구매는 1회 결제로 해당 악보를 결제 시점부터 180일 동안 이용하는 상품입니다. 180일 동안 뷰어 열람·개인 용도 인쇄·PDF 다운로드가 제공되며, 180일 안에 PDF를 저장하는 것은 구매자의 책임입니다. 기간이 정상적으로 끝나면 저장한 파일은 개인·비상업 용도로 계속 보관할 수 있고, 새 다운로드·사이트 열람·인쇄만 중단되며 같은 악보를 다시 구매할 수 있습니다. 주문이 환불되면 그 주문으로 받은 이용 허락은 계정 이용 권한과 함께 종료됩니다(환불정책 참조). 저희가 기기에 저장된 파일을 삭제하지는 않지만, 환불된 주문의 파일을 계속 이용할 권리는 없습니다. 열람 시작 여부와 관계없이 환불 요청 권리는 유지되며, 환불은 환불정책과 관계 법령을 따릅니다.

Sheets purchased before 22 October 2026 under the earlier individual-sheet terms keep the access terms shown at the time of purchase (available through the purchasing account without a fixed time limit while the service continues to operate).

2026년 10월 22일 이전에 종전 개별 악보 조건으로 구매한 악보는 구매 당시 안내된 조건(서비스 운영 기간 중 기간 제한 없는 이용)을 그대로 따릅니다.

In-app 180-day song access (Try Piano).In the Try Piano app you may buy 180-day access to a single song (currently US$9.90, shown in the store’s local currency). It unlocks that song’s full tutorial in the app and lets you view, save, share to your own devices, and print the song’s sheet music PDF for personal use during the 180-day period. When the period ends, new downloads stop; copies you already saved remain yours for personal, non-commercial use. In-app song access is a separate product from the web individual sheet purchase in this section and does not unlock the web Viewer, Music Pass, or Academy. Purchases, refunds, and cancellations made through Google Play are governed by Google Play’s policies.

Try Piano 앱에서는 곡 1개의 180일 이용권(현재 US$9.90 · 스토어 현지 통화로 표시)을 구매할 수 있습니다. 이용권은 해당 곡의 전체 튜토리얼을 열고, 180일 동안 개인 소장·연습용으로 그 곡의 악보 PDF를 보기·저장·내 기기로 공유·인쇄할 수 있게 합니다. 기간이 끝나면 새 다운로드만 중단되며, 이미 저장한 사본은 개인·비상업 용도로 계속 보관할 수 있습니다. 앱 내 곡 이용권은 이 조의 웹 개별 구매와 별개의 상품이며 웹 뷰어·Music Pass·Academy를 열지 않습니다. Google Play로 결제한 구매·환불·취소는 Google Play 정책을 따릅니다.

5. Subscriptions: Music Pass and Academy

Music Pass and Academy are two separate subscriptions, each with its own price, billing cycle, renewal, and cancellation. Neither includes the other, and you may hold both at the same time. Canceling or losing one never affects the other.

Each subscription renews automaticallyat the end of every billing period and the then-current price is charged to your payment method, until you cancel. You can cancel at any time from your account (or through the payment provider’s cancellation method); cancellation stops future renewals and your access continues until the end of the period already paid, after which it ends. Subscription prices may change; we will notify active subscribers before a price change takes effect so you can cancel first.

Music Pass sheet credits.Music Pass includes 3 sheet credits per billing cycle. Each credit unlocks one sheet of your choice for 180 days from the moment you select it — reading in the Viewer, printing, a PDF download, and practice in the Try Piano app where the song is supported. Membership alone does not open the catalog; sheets you have not selected show their free preview only. Unused credits do not carry over to the next cycle. Selections you have already made continue to the end of their 180 days after you cancel; a full refund of a billing cycle ends the selections made with that cycle’s credits. Music Pass+ adds full Try Piano access and an ad-free Try Piano app; its credits are the same 3 per cycle.

Music Pass에는 매 결제 주기마다 악보 크레딧 3개가 포함됩니다. 크레딧 1개는 선택한 순간부터 180일 동안 원하는 악보 1곡을 엽니다(뷰어 열람·인쇄·PDF 다운로드·앱이 지원하는 곡의 Try Piano 연습). 멤버십만으로는 카탈로그가 열리지 않으며, 선택하지 않은 악보는 무료 미리보기만 표시됩니다. 사용하지 않은 크레딧은 다음 주기로 이월되지 않습니다. 이미 선택한 악보는 해지 후에도 각각의 180일이 끝날 때까지 이용할 수 있고, 결제 주기 전액 환불 시 그 주기의 크레딧으로 선택한 악보의 이용이 종료됩니다. Music Pass+는 Try Piano 전곡 이용과 Try Piano 앱 광고 제거를 더하며, 크레딧은 똑같이 주기당 3개입니다.

6. Payment processing

Payments on the Service are processed by Paddle as Merchant of Record— Paddle is the seller of record for those transactions, processes your payment, handles applicable taxes, and issues receipts, and Paddle’s checkout terms apply alongside these Terms. Purchases made inside our apps are processed by the app store you bought from (Google Play or the Apple App Store) under that store’s terms. Additional payment methods or processors (for example, a Korean payment provider for domestic payments) may be offered later; the checkout page will always identify who processes your payment.

7. License and intellectual property

All sheet music, recordings, course materials, and site content are protected by copyright and remain the property of 주식회사 SAIR and/or their respective rights holders. A purchase or subscription grants you a personal, non-exclusive, non-transferable license to view, print (where offered), and use the content for private, non-commercial purposes. You may not copy, redistribute, resell, publicly post, sublicense, or share purchased files or your account access with others, and you may not remove watermarks or circumvent content protection. This includes sending purchased files to others or uploading them to websites, communities, or resale platforms; such use is copyright infringement. Public performance, recording, or commercial arrangement rights are not included unless a product page expressly grants them.

구매한 파일을 타인에게 전송하거나 웹사이트·커뮤니티·재판매 플랫폼에 올리는 행위를 포함하며, 이는 저작권 침해에 해당합니다.

8. Prohibited use

You must not:

  • share, resell, or publicly redistribute digital content;
  • circumvent access control, watermarking, or preview protection;
  • remove, alter, or obscure watermarks, license notices, or buyer-identification information in downloaded files;
  • scrape, mass-download, or programmatically extract content;
  • use the Service for unlawful purposes or infringe others’ rights;
  • interfere with the operation or security of the Service.

9. Suspension

We may suspend or restrict an account that materially violates these Terms — including content redistribution or payment abuse — after reasonable consideration and, where practicable, notice. Suspension for cause does not by itself create a refund obligation, except where applicable law provides otherwise.

10. Availability and changes

We aim to keep the Service available and continuously improve it, but we may change, add, or discontinue features. If we discontinue content you have paid for, we will provide a reasonable remedy — such as continued access for the paid period or a proportional refund — as required by applicable law. If the service is discontinued, the company will provide advance notice and take appropriate measures in accordance with applicable law, these Terms, and any separate service-closure notice.

11. Disclaimers

Except as expressly stated or required by law, the Service is provided “as is” and we make no warranties regarding uninterrupted availability or fitness for a particular purpose.

12. Limitation of liability

To the extent permitted by applicable law, our aggregate liability arising out of the Service is limited to the amount you paid us in the twelve months before the claim. Nothing in these Terms excludes or limits liability that cannot be excluded by law, including liability arising from our intentional misconduct or gross negligence.

13. Governing law and consumer rights

These Terms are governed by the laws of the Republic of Korea. Nothing in these Terms limits mandatory statutory consumer rights under the laws of the Republic of Korea (including the Act on Consumer Protection in Electronic Commerce) or under the mandatory consumer-protection laws of your country of residence.

14. Changes to these Terms

We may update these Terms. Material changes will be announced on the Service before they take effect; the “Last updated” date above always reflects the current version.
