Terms of Service

1. Provider, scope and agreement

Amadeo is provided by Brandenburger Digital Systems UG (haftungsbeschränkt), Ströherstraße 20, 35683 Dillenburg, Germany, represented by managing director Dennis Brandenburger. Contact: info@amadeo-piano.com; registration and tax details are in the legal notice.

These terms cover Amadeo’s learning features, content, accounts and online services. They become part of a contract only when made available before contract formation and validly agreed. Merely visiting this website does not constitute acceptance of a paid contract.

The iOS app licence is governed by Apple’s standard EULA, unless a separate licence is validly agreed. These terms supplement it for our services. Apple does not provide our learning service; its own Store terms also apply. Mandatory statutory rights remain unaffected.

2. Learning service and requirements

Amadeo supports piano learning through piece-specific learning paths, practice views, fingering, stories and guidance from the virtual coach Amadeus, and additional Gym exercises. The product description agreed at purchase determines the service. The website presents the product; the app is obtained separately through an enabled Store.

You need a compatible device and an acoustic piano, digital piano or keyboard. Recognition uses the microphone or a supported MIDI connection. Background noise, the instrument, connection and device can affect recognition. The app supports independent practice without promising a particular learning outcome or flawless recognition in every setting. Expression and articulation are coached rather than definitively graded.

Current system requirements are shown in the Store. Accounts, sync, support, purchases and downloading voice clips require an internet connection. Bundled musical data remains local; the operating system may remove cached files. Your network provider’s charges remain your responsibility.

3. Account and minors

Basic local use does not require an account. An optional Sign in with Apple account supports backup, sync and account-bound access. Each account is intended for one learner. Protect your Apple access and report suspected misuse. You are not liable without fault for every instance of third-party access.

At launch, our offering is intended for adult individuals. It does not include child accounts or shared management of multiple learner profiles. The Store age rating does not determine legal capacity. Country and device availability are stated in the relevant Store listing.

4. Free access, piece purchases and Pro

The first chapter of each piece is free. Listening to complete pieces and free practice with both hands are included in free access. Further chapters and certain practice tools may be unlocked for an individual piece or through an Amadeo Pro subscription. The specific features and prices shown before purchase confirmation govern the offer.

An individual purchase covers the named piece, not a subscription to the entire catalogue. Pro provides the described additional features during the paid service period. Cancelling Pro does not in itself remove individual purchases. There is no blanket promise of all future features, catalogue additions or indefinitely available servers.

5. Store purchases, renewal and cancellation

Paid offers become available only after Store approval. On iOS, billing takes place through the Apple App Store. The seller, total price including applicable taxes, features, billing period and any trial shown before checkout govern the transaction. This website does not process purchases. Apple handles payment details.

An auto-renewing subscription renews under the terms agreed in the purchase dialog unless you cancel it in time in your Apple account. Manage it through Apple subscriptions. The renewal and cancellation deadlines shown there apply; Apple free or discounted trials may require cancellation at least 24 hours before expiry. A trial exists only where the specific offer includes one.

Cancellation stops future renewals. Paid access normally continues until the agreed period ends; statutory termination and refund rights remain unaffected. Uninstalling Amadeo or deleting its account does not cancel an Apple subscription.

For Germany, Apple also describes a right to cancel a subscription with immediate effect and receive a prorated refund by contacting Apple Support. See Apple’s country-specific cancellation guidance. Ordinary cancellation through device settings instead stops the next renewal.

6. Restoration and account association

Subscriptions can be checked through Restore purchases using the relevant Store account. Individual piece unlocks are additionally bound to the Amadeo account used for purchase. Sign back in with that same account to access them. Store restoration does not automatically transfer them to another Amadeo account.

Deleting the account permanently removes that technical association. The app explains the consequences before deletion. This technical description does not waive statutory claims arising from a paid contract. For a lost association, contact support with the necessary proof of purchase; do not send full payment details. Family Sharing or cross-platform transfers apply only where provided by the specific offer and Store rules.

7. Withdrawal, refunds and statutory remedies

For a distance contract under German law, consumers generally have a 14-day withdrawal period starting when the contract is concluded. Statutory conditions and exceptions, and any further mandatory rights in your country of residence, apply. Store transactions are subject to the withdrawal information supplied during checkout and the contracting party identified there. For Apple purchases, you can use purchase history or Apple’s purchase and refund process. This does not restrict other legally permitted ways of giving notice.

For digital content, a withdrawal right does not expire merely because you download the app or accept these terms. The statutory requirements, including the necessary express declarations and confirmation, must be met (section 356 BGB). Withdrawal, ordinary subscription cancellation and a defect-related refund are distinct rights. Applicable remedies under sections 327 et seq. BGB and claims against us as provider remain available.

Where a contract subject to withdrawal is directly with us, a clear statement to the postal or email address above is sufficient. Sending it before the deadline meets the time limit. Following withdrawal, we reimburse the relevant payments without undue delay and within 14 days of receiving your notice, using the same payment method unless expressly agreed otherwise without additional fees. Statutory conditions for proportionate payment for services already supplied at your express request remain unaffected.

8. Updates and service changes

We provide legally required updates, including security updates, for the applicable period and inform you about them. For continuous supply this is generally the supply period; for a one-off supply, statutory criteria determine the period. Install necessary updates after being informed. Legal consequences of not installing an update apply only where their statutory requirements are met.

Additional changes during continuous supply require a valid contractual reason: necessary adaptation to changed operating systems or interfaces, responding to specific security risks, complying with new legal requirements, or maintaining the service when a required third-party provider fails. They must not cause additional charges. This is not permission to discontinue paid services at our sole discretion.

For more than minor adverse effects, we inform you in advance on a durable medium about the change, timing and rights. The statutory right to terminate without charge under section 327r BGB, including its 30-day period from notice or a later change and its statutory exceptions, remains unaffected.

9. Usage rights and permitted use

Within the agreed scope, you may use Amadeo for your personal piano learning. Legally permitted uses and Store licence rules remain unaffected. These terms do not turn public-domain compositions into our property. Protectable software, artwork, editions, recordings, text and trademarks remain with their respective rights holders.

Bypassing access or security controls, accessing other people’s accounts and unauthorised distribution of protected app content are prohibited. Mandatory rights concerning interoperability, security research or other permitted uses are not excluded wholesale. Support messages must not contain unlawful content or unnecessary personal data about others.

10. Availability, support and termination

Maintenance or faults can temporarily affect online features. This does not remove agreed availability commitments or statutory remedies. Contact us through in-app support or the email address above. A fixed response time applies only if separately agreed.

You can stop using the app and delete your account in the app. Export any data you wish to keep first. For serious unlawful or security-threatening use, we may restrict affected access proportionately; where reasonable, we inform you and allow an opportunity to remedy it. Termination for cause follows the legal requirements. Accrued claims and statutory refund rights remain unaffected.

11. Liability

Our liability is unlimited for intent and gross negligence, injury to life, body or health, fraud, an expressly assumed guarantee, and mandatory statutory liability, including applicable product-liability law.

For ordinary negligence otherwise, we are liable for breach of essential contractual obligations that enable proper performance and on which you may normally rely. Liability is then limited to foreseeable loss typical of the contract. Other ordinary-negligence liability is excluded. The exceptions above and mandatory consumer and data-protection rights remain unaffected. These limits also apply to persons acting on our behalf.

12. Privacy, amendments and governing law

The privacy notice explains personal-data processing. Acknowledging it is not blanket consent. Amendments to these contractual terms do not become effective merely through publication or your silence; where required, we obtain your agreement. Permitted service changes follow the Updates and service changes section.

German law applies while preserving applicable mandatory consumer protection in your country of habitual residence. Statutory jurisdiction is not restricted to your disadvantage. If a provision is invalid, statutory rules apply and the remainder continues to the extent provided by law.

We are neither willing nor obliged to participate in proceedings before a consumer arbitration body (section 36 VSBG). You can still contact us directly about questions or complaints.
