Terms of Service

Neural-Fretboard (“the Service”, “we”, “us”) is operated by [Full name / company], [address] (see the Imprint). These terms apply to all use of the website and apps. Deviating terms of the user do not apply unless we have agreed to them in writing.

Neural-Fretboard is a web application that visualises music on a guitar fretboard. It lets you upload or record MIDI, audio (MP3/WAV) or Guitar Pro files, transcribe audio to MIDI in your browser, compose in a step-sequencer, browse a chord library, tune your guitar, and practise with your microphone. Audio processing runs on your device; see the Privacy Policy.

Some features require an account. You must provide accurate information, keep your login credentials confidential, and are responsible for activity under your account. You must be at least 16 years old, or have the consent of a parent or legal guardian. We may suspend or terminate accounts that violate these terms.

The Service offers a Free plan and a paid Creator subscription. Current prices and the scope of each plan are shown on the Pricing page. The Creator subscription costs €7.99 per month or €59 per year (or the price shown at checkout), including VAT where applicable.

Payment is processed by Stripe. The subscription contract is concluded when you complete checkout and we confirm the payment. It renews automatically for the chosen billing period (month or year) until cancelled. You can cancel at any time with effect from the end of the current billing period; access to the paid features continues until then. Prices are in euros. We may change prices for future billing periods with reasonable advance notice; if you do not agree, you can cancel before the change takes effect.

The paid Creator subscription is sold through Stripe and its Link checkout, acting as Merchant of Record and seller for the payment. Stripe/Link processes the payment, issues the invoice, collects and remits VAT, and handles refunds and payment disputes. The purchase may appear as “Sold through Link” on your card or bank statement. The service itself is provided by [Full name / company] (see the Imprint).

For the duration of an active Creator subscription we grant you a non-exclusive, non-transferable, worldwide licence to use the paid features for your own personal use, including publishing videos you export. The licence ends when the subscription ends; content you exported while subscribed remains yours. If we permanently discontinue the Service, we will give reasonable notice where possible.

If you are a consumer, you have a statutory 14-day right of withdrawal when you take out the Creator subscription. Because the subscription is a digital service that begins immediately with your express consent, this right can expire early (§ 356 (5) BGB). Details are in the separate Right of Withdrawal notice, which forms part of these terms and includes the model withdrawal form.

You keep all rights to the files you upload or create (MIDI, audio, compositions). You grant us only the limited, technical right to store and process them so we can provide the Service to you (e.g. saving to your library). You are responsible for the content you upload and confirm, when prompted, that you hold the necessary rights to it. You must not upload content that infringes third-party copyright or other rights.

You agree not to:

• ›use the Service unlawfully or to infringe others’ rights;
• ›circumvent access controls, plan limits, or payment;
• ›reverse engineer, scrape, or overload the Service, or disrupt its operation;
• ›resell or sublicense access without our written permission;
• ›upload malware or content that is illegal, harmful, or infringing.

The Service itself, including its software, design, brand, logo, text and graphics, is protected by copyright and other rights and remains our property or that of our licensors. Nothing in these terms transfers those rights to you beyond the licence to use the Service as intended.

We aim for high availability but do not guarantee uninterrupted, error-free operation; maintenance, updates and technical faults can cause downtime. Features labelled “Beta” are provided as-is and may change or be removed. Some features depend on your browser and hardware (WebGL, Web Audio, microphone).

For paid services, your statutory warranty rights apply. Otherwise the Service is provided “as is” to the extent legally permitted.

We are liable without limitation for damages arising from injury to life, body or health, from intent or gross negligence, and under the German Product Liability Act (ProdHaftG). For slight negligence we are liable only for the breach of an essential contractual obligation (cardinal duty), and then limited to the foreseeable, typical damage. Any further liability is excluded. This limitation also applies to the personal liability of our staff and agents.

You may stop using the Service, cancel your subscription, and delete your account at any time. We may terminate or suspend access for good cause, in particular a serious breach of these terms. A Creator subscription ends when you cancel it (at the end of the billing period), if you delete your account, or if the Service is permanently discontinued.

We may amend these terms where there is a valid reason (e.g. changes to the Service or the legal situation). We will notify registered users of material changes in a reasonable manner and in good time before they take effect. If you do not agree, you may terminate your account before the changes apply.

We are neither obliged nor willing to participate in dispute settlement proceedings before a consumer arbitration board within the meaning of the German Consumer Dispute Resolution Act (VSBG). The former EU platform for online dispute resolution was discontinued by the European Commission on 20 July 2025 and is no longer available.

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of your country of habitual residence. If you are a merchant, legal entity under public law or a special fund under public law, the exclusive place of jurisdiction is our registered seat.

Should any provision of these terms be or become invalid, the validity of the remaining provisions is not affected.
