Terms of Service
Agreement and operator — These terms govern the agreement between you and the Hello, Piano operator, 안녕,쏘잉, for the account or service you request and use. Personal data is handled as described in the Privacy Policy; reading that notice or using the service is not treated as blanket consent to every form of processing. The operator obtains separate consent when a particular processing activity requires it. Mandatory rights under applicable consumer and privacy law continue to apply.
Service scope — Hello, Piano provides score viewing, MIDI-guided and rhythm practice, device-local practice records and playback, a private web score library, analysis, and requested score-conversion tools. Available features depend on device, MIDI hardware, file format, plan, account policy and release region. Practice analysis and converted notation are assistive results and may contain recognition, rhythm, pitch, layout or compatibility errors; check important results against the original score.
Accounts and security — Provide accurate sign-in information, keep credentials and devices secure, and notify support of suspected unauthorized use. A Piano account is an app-specific profile linked to a shared Hello identity. Piano withdrawal removes Piano service data as described in the Privacy Policy but does not delete other Hello services or device-local files. You may not sell or lend an account, impersonate another person, use automated means to abuse the service, or use another person's account without authority.
Plans, credits and quotes — The Basic Plan includes one bookshelf and up to ten scores, subject to the published feature description. Pro features and the amount of monthly credits follow the offer displayed when you subscribe; a stale fixed amount in older materials does not override the current published offer. Unused credits carry over unless a lawful, clearly disclosed offer states otherwise. Manual PDF or photo conversion is currently priced at 500 credits per confirmed score page. The page count, unit price, discounts if any, and total returned by the server and shown for your confirmation form the final quote for that request. No charge is made merely for viewing an original or reopening an existing report.
Store subscriptions, cancellation and refunds — Subscription and credit purchases are processed by the Apple App Store or Google Play under the price, renewal and payment information shown by that store. Cancel a subscription in the store where it was purchased; deleting the Piano account does not cancel billing or request a refund. Submit store-payment refund requests through that store and contact support when the operator can assist. These terms do not exclude statutory withdrawal, cancellation, refund, defect-remedy or dispute rights. Treatment of supplied digital content or used credits is limited to what applicable law and the purchase consent permit.
Score conversion and corrections — A manual conversion request requires the necessary credit balance or an eligible benefit, consent to authorized administrator access, and confirmation of the server quote. Requests are handled in order and have no guaranteed completion time. A request cancelled while eligible or rejected or failed by the operator restores the amount actually charged once. Direct MusicXML imports remain read-only in the web editor; supported corrections are limited to measures identified for review. The service may reject unsupported, unsafe, incomplete, unlawfully supplied or technically excessive files.
Your content and license — You retain rights you hold in uploaded scores, recordings, metadata and correction instructions. You confirm that you have the rights or permission needed to upload, process, convert and practice with them. You grant the operator a limited, non-exclusive license, for only as long and as far as needed, to store, reproduce, render, transmit, inspect and transform that content to provide your requested service, secure it, resolve support issues and meet legal duties. This license does not permit public distribution or independent sale of your private content. Except for public-domain material and third-party material governed by its own open or other license, the service software, interface, brand and operator-created materials remain protected, and you receive a personal, revocable, non-transferable license to use them through the service. Nothing in these terms narrows rights granted by an applicable public-domain status or third-party license.
Copyright reports — Rights holders may send a notice to hello.official.team@gmail.com identifying the protected work, the specific service content or location, contact information, the basis of authority and a good-faith explanation. The operator may request verification, restrict access while reviewing, notify the affected user and take proportionate action. A user may submit supporting information in response. This process does not limit remedies available under applicable law.
Acceptable use and tester benefits — Do not infringe rights, upload malware or unlawful content, bypass access or credit controls, interfere with the service, scrape private data, reverse engineer beyond rights granted by law, or use the service to attack others. Tester benefits expire on the operator-set date, grant no wallet credits, allow up to three conversion requests, restore failed or cancelled allowances and block real purchases. Creating, deleting or rejoining Piano accounts to reset a benefit is prohibited; the minimal anti-abuse record described in the Privacy Policy may remain tied to the shared Hello identity.
Availability, suspension and changes — The operator may maintain, repair or protect the service and may suspend an account or content when reasonably necessary for security, abuse prevention, rights protection or law. When practical, the operator will explain the reason and offer a way to contact support. Material unfavorable changes to these terms, paid features or data practices will receive clear advance notice in the website, app or account contact channel. Urgent legal or security changes may take effect sooner, with notice as soon as practical. Accrued payment, refund and consumer rights are not removed by a service change.
Responsibility and liability — The operator will use reasonable care in providing the service and is responsible for loss caused by its intentional or negligent breach to the extent provided by law. The operator is not responsible to the extent a loss is caused by the user's unlawful action, unsupported equipment or files, or an event outside reasonable control despite appropriate care. Nothing in these terms excludes or limits liability for intent or gross negligence, personal injury where exclusion is prohibited, or non-waivable consumer rights.
Ending use and disputes — You may stop using the service or delete the Piano account at any time, subject to separate store cancellation and legally retained records. The operator may end the service or an account for a material or repeated breach after reasonable notice and an opportunity to respond when appropriate; urgent protective action may be immediate. Contact hello.official.team@gmail.com first so the operator can try to resolve a complaint. Korean law applies where applicable, without depriving a consumer of mandatory protections in the consumer's place of residence, and disputes may be brought before a court or consumer-dispute body with jurisdiction.
