OK Instruments — Last updated: March 2026
(1) These Terms and Conditions (hereinafter "Terms") apply to all contracts between OK Instruments (hereinafter "Provider") and the customer (hereinafter "Customer") regarding the supply of software, hardware kits, and digital content via the website ok-instruments.com and the associated online shop.
(2) Deviating, conflicting, or supplementary terms of the Customer shall only become part of the contract if the Provider has expressly agreed to their validity in writing.
(3) A "consumer" within the meaning of these Terms is any natural person who enters into a legal transaction for purposes that are predominantly neither commercial nor self-employed (§ 13 BGB). An "entrepreneur" is any natural or legal person or a partnership with legal capacity who, when concluding a legal transaction, acts in the exercise of their commercial or self-employed professional activity (§ 14 BGB).
(1) The presentation of products in the online shop does not constitute a legally binding offer but rather an invitation to place an order (invitatio ad offerendum).
(2) By clicking the order button, the Customer submits a binding purchase offer. The Provider confirms receipt of the order without delay by email (order confirmation). This order confirmation constitutes acceptance of the offer; the contract is concluded upon receipt of the order confirmation.
(3) For free downloads (e.g. beta versions), the licence agreement is concluded upon completion of the download.
(1) All prices shown are final prices and include statutory VAT where applicable. Any shipping costs are shown separately and are borne by the Customer.
(2) Payment is made via the payment methods offered in the shop (e.g. credit card, PayPal, Shopify Payments). The purchase price is due upon conclusion of the contract.
(3) For digital products (software licences, downloads), delivery takes place immediately upon receipt of payment.
(1) Digital products (software): Delivery is provided as a download via the website. After receipt of payment, the Customer receives a download link by email or via their customer account.
(2) Hardware kits: Shipping is made to the delivery address provided by the Customer. Delivery times are indicated on the respective product page. Delays caused by force majeure or supply shortages from suppliers do not give rise to any claim for damages.
(3) For consumers, the risk of accidental loss or deterioration of the goods passes to the Customer upon delivery. For entrepreneurs, the risk passes upon handover to the carrier, freight forwarder, or other person designated to carry out the shipment.
(1) The Provider grants the Customer a simple (non-exclusive), perpetual right to use the purchased software. Use is restricted to the Customer personally.
(2) The Customer may install the software on any number of their own devices, provided the software is only used by one person at a time.
(3) The Customer may not reproduce, distribute, rent, lend, sub-licence, or make the software publicly available unless expressly permitted by law (§§ 69d, 69e UrhG — German Copyright Act).
(4) Reverse engineering, decompilation, and disassembly are only permitted to the extent allowed by law (§ 69e UrhG).
(5) Beta software: Beta versions are provided free of charge and "as is." The Provider makes no warranty regarding the functionality or freedom from defects of beta versions. Use is at the Customer's own risk.
(6) AI-generated content: Content that the Customer creates using the integrated AI features (e.g. sound generation) may be used freely by the Customer, including for commercial purposes. The Provider claims no rights to content generated by the Customer. The Customer shall indemnify the Provider against any third-party claims arising from the use of generated content.
(1) LoRA adapters and other model extensions offered via the website or within the software are subject to the licence terms of the underlying base model (e.g. MusicGen CC-BY-NC 4.0).
(2) It is the Customer's responsibility to review and comply with the respective base model licence terms, particularly regarding commercial use.
(1) Hardware kits are shipped as self-assembly kits. Assembly requires basic knowledge of soldering and handling electronic components.
(2) The Provider is not liable for damage caused by improper assembly, modification, or use of incompatible components by the Customer.
(3) For pre-assembled hardware products (if offered), statutory warranty rules apply without restriction.
(1) Consumers have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the date of conclusion of the contract (for digital products) or from the date on which the Customer or a third party designated by the Customer has taken possession of the goods (for hardware).
(2) To exercise the right of withdrawal, the Customer must inform the Provider by means of a clear statement (e.g. via the contact form) of the decision to withdraw from this contract.
(3) Exclusion for digital content: The right of withdrawal expires for contracts for the supply of digital content not supplied on a tangible medium if the Provider has begun performance of the contract after the Customer has expressly consented to the Provider beginning performance before the expiry of the withdrawal period, and the Customer has confirmed awareness that consent results in the loss of the right of withdrawal (§ 356 (5) BGB).
(4) In the event of a valid withdrawal, the services received by both parties shall be returned. The Provider shall refund all payments without delay and no later than fourteen days from the day on which notification of the withdrawal was received.
(1) Statutory warranty rights apply.
(2) For consumers, the limitation period for warranty claims on new goods is two years from delivery.
(3) For entrepreneurs, the limitation period for warranty claims is one year from delivery. This does not apply to claims arising from injury to life, body, or health.
(4) Software updates: The Provider provides updates at its own discretion. The Customer has no entitlement to future updates or new features unless the update is necessary to maintain conformity pursuant to § 327f BGB.
(1) The Provider is liable without limitation for damages arising from injury to life, body, or health attributable to a negligent or intentional breach of duty by the Provider or its legal representatives or vicarious agents, as well as for damages covered by the German Product Liability Act (Produkthaftungsgesetz) and for all damages based on intentional or grossly negligent breaches of duty.
(2) In cases of slightly negligent breach of material contractual obligations (cardinal obligations), the Provider's liability is limited in amount to the foreseeable, contract-typical damage at the time the contract was concluded. Material contractual obligations are those whose fulfilment is essential for the proper performance of the contract and on whose compliance the Customer may regularly rely.
(3) Beyond this, the Provider's liability for slightly negligent breaches of duty is excluded.
(4) Data loss: The Provider is liable for data loss only up to the amount that would have been incurred for restoration if the Customer had carried out proper and regular data backups.
(1) Personal data is processed in accordance with the EU General Data Protection Regulation (GDPR) and the German Federal Data Protection Act (BDSG).
(2) Details on data processing are described in the Privacy Policy, available at privacy.html.
(3) Local AI processing: The AI features included in the software are executed exclusively on the Customer's local device. No audio data, prompts, or results are transmitted to servers of the Provider or third parties.
(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). For consumers who have their habitual residence in another EU member state, mandatory provisions of the law of that member state remain unaffected.
(2) If the Customer is a merchant, a legal entity under public law, or a special fund under public law, the Provider's registered office is the exclusive place of jurisdiction for all disputes arising from this contract.
(3) Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions shall not be affected. In place of the invalid provision, a valid provision shall be deemed agreed that comes closest to the economic purpose of the invalid provision.
(4) The Provider reserves the right to amend these Terms with effect for the future. The Customer will be notified of changes in good time. If the Customer does not object to the new Terms within six weeks of notification, the amended Terms shall be deemed accepted.
