Terms of Service

Effective 2026-11-06Version 1.0Operator Vicino Labs

These terms are the agreement between you and Vicino Labs for using Chiave, a sheet music app. By installing and using the app you agree to them.

1. Scope

These terms govern the use of the mobile app Chiave (the “app”) provided by Vicino Labs (the “company”).

2. Provider

The operator's address and contact details are at the end of this document and in the Impressum.

3. Validity and changes

  1. These terms take effect when published in the app or in another way chosen by the company.
  2. The company may change them within the law and will announce the effective date and reason in advance.
  3. If you do not agree to changed terms, you may stop using and delete the app.

4. What the app offers

  1. Writing and editing scores, transposing, and listening with a piano sound
  2. Score scanning (optional): pages from the camera, photo album or a PDF are read by AI and turned into an editable score. Scanned pages are counted according to your plan.
  3. Export: PDF, PNG image, MusicXML, editable file
  4. The Free plan shows a link to welegato, a service of the same company, at the bottom of the screen.
  5. There is no sign-up; scores are stored only on your device.

5. Plans and subscriptions

  1. Free trial: everyone can scan 3 pages during the first 7 days. The trial is available once per device and does not restart when you reinstall the app. Afterwards the Free plan applies; there is no automatic payment.
  2. Free: 1 scanned page per month
  3. Pro: 20 scanned pages per month, no banner
  4. Pro+: 50 scanned pages per month, no banner
  5. Pro and Pro+ are monthly subscriptions, billed by Google Play or the Apple App Store at the price shown in the store. They renew for the same period until cancelled; cancel any time in the store's subscription settings. A subscription keeps working until the paid period ends; afterwards the Free plan applies.
  6. Scan pages have no cash value and cannot be transferred.
  7. Prices are shown in the store before you buy and may differ by country. Payment and refunds follow each store's rules and process. For digital content, if you agree that use starts immediately, your right of withdrawal may end as far as the law allows; the store's refund process remains available.
  8. Changes to the monthly pages or plan terms are announced in advance and do not apply to periods already paid.

6. Score scanning

  1. Scan results are read by AI and can contain wrong or missing notes. Please check them against the original before performing or publishing.
  2. Only scan scores you have the right to use.
  3. We may limit use to prevent abuse.

7. Scores and copyright

  1. You are responsible for respecting copyright in the scores you write, scan, transpose, export or share in the app.
  2. The company does not keep your scores on its server. The strip images sent for scanning are used only to recognise the notes and are not stored.

8. welegato and external services

The app links to and uses external services such as welegato, the store pages of other Vicino Labs apps, Google Play and the App Store. They are separate from the app and governed by their own terms and privacy policies. The company is not responsible for their content or availability.

9. Intellectual property

The company holds the rights to the app's logo, the name “Chiave”, its design, texts and source code. You may not copy, distribute, transmit, publish, reverse-engineer or create derivative works without prior written consent.

10. Your obligations

  1. Do not reverse-engineer or decompile the app or circumvent payment or page limits.
  2. Do not disrupt the app's normal operation.
  3. Comply with applicable law and these terms.

11. Changes and discontinuation

The company may change or discontinue all or part of the app for operational or technical reasons and will announce this in advance unless urgent. Changes to external services (such as Google Gemini) may limit related features.

12. Liability

  1. The company is liable without limitation for intent and gross negligence, for injury to life, body or health, and under the Product Liability Act.
  2. For slight negligence the company is liable only for breach of essential contractual obligations, limited to the typical damage foreseeable when the contract was made.
  3. Scores are stored only on your device and there is no cloud backup. To protect against loss of the device, deletion or reset, please keep important scores yourself by exporting them.

13. Governing law and jurisdiction

German law applies. Mandatory consumer-protection rules of the country where you, as a consumer, habitually reside (e.g. an EU member state) remain unaffected. Otherwise the courts at the company's seat (Dortmund, Germany) have jurisdiction.
