(6) In the event of contradictions, the following order of precedence applies:
- individual written agreements or agreements made in text form,
- offer and service description,
- separate data protection, confidentiality, security, data, or service-level agreements,
- these Terms and Conditions.
§2 Subject Matter of the Contract
(1) KnowFab provides services in particular in the following areas:
- provision of software solutions and AI models, in particular as SaaS, license model, on-premise solution, or API integration,

(2) The specific scope of services is determined exclusively by the respective offer, service description, or other individual contractual agreement.
(3) KnowFab owes only the expressly agreed services. Services beyond this, in particular certifications, safety approvals, standards-related product tests, series approvals, component approvals, process approvals, or regulatory conformity assessments, are owed only if expressly agreed.
(4) Technical, economic, or qualitative forecasts, savings potential, model metrics, accuracy values, process improvements, or quality improvements constitute a warranted characteristic or guarantee only if expressly agreed as such.
§3 Conclusion of Contract
(1) Offers from KnowFab are non-binding unless expressly designated as binding.
(2) A contract is concluded when the customer accepts an offer from KnowFab. Acceptance may be made in text form, in particular by email.
(3) If KnowFab begins providing services at the customer's request and the customer makes use of such services, a contract may also be concluded by conclusive conduct.
(4) Changes or extensions to the scope of services require a separate agreement. KnowFab is entitled to charge separately for additional effort resulting from such changes, unless such effort is already covered by the agreed scope of services.
§4 Nature of Services
(1) Unless expressly agreed otherwise, KnowFab provides services as service work.
(2) No specific economic success, in particular specific savings, reductions in scrap, productivity increases, quality improvements, or a specific process stability, is owed unless expressly agreed.
(3) Work-contract services, deliverables subject to acceptance, or specific technical characteristics are owed only if expressly agreed in the offer or service description.
(4) The systems, models, analyses, and reports provided by KnowFab serve the technical analysis and support of professional decisions. They do not replace the customer's own review, assessment, validation, or approval decision.
(5) The customer remains responsible for the assessment, implementation, and control of measures taken on the basis of results, recommendations, analyses, or forecasts from KnowFab.
§5 Availability, Maintenance, and Support
(1) Support services are provided by email during KnowFab's business hours. Business hours are Monday to Friday from 09:00 to 16:00, excluding public holidays at KnowFab's registered office.
(2) A specific response time, resolution time, or availability is owed only if expressly agreed in the offer, in a service level agreement, or in another individual contractual agreement.
(3) Unless a specific availability has been expressly agreed, KnowFab does not owe any specific minimum availability of the software or individual services. KnowFab will, however, endeavor to provide the agreed services with reasonable care.
(4) Planned maintenance work will be announced to the customer in advance where possible. Urgent maintenance work, in particular for security, error correction, system stability, or prevention of disruptions, may also be carried out without prior notice.
(5) Impairments caused by the customer's networks, systems, infrastructure, interfaces, hardware, software, security policies, or access rights, or by third parties used by the customer, are outside KnowFab's area of responsibility.
(6) KnowFab is entitled to temporarily restrict or suspend services insofar as this is necessary for reasons of security, system integrity, error correction, maintenance, or prevention of damage.
§6 Customer Cooperation Obligations
(1) The customer is obliged to provide all information, data, documents, contact persons, system access, interface descriptions, test environments, and other cooperation required for the provision of services in a timely, complete, and suitable form.
(2) The customer is responsible in particular for:
- the quality, completeness, up-to-dateness, and suitability of the provided data,

- compliance with its own inspection, documentation, approval, and quality assurance processes,
- the functionality of its systems, infrastructure, and interfaces,
- the establishment of suitable review and control mechanisms.
(3) Delays or additional effort resulting from insufficient, delayed, or faulty cooperation by the customer shall not be borne by KnowFab. KnowFab is entitled to charge separately for additional effort resulting therefrom.

(2) KnowFab receives a simple, non-exclusive right to use customer data to the extent necessary to provide the agreed services.
(3) Use of customer data for KnowFab's own purposes, in particular for general product development, model improvement, benchmarking, publication, training, or reuse towards other customers, takes place only if expressly agreed.
(4) If use of customer data to improve models or products is agreed, such use will, where technically possible and sufficient for the respective purpose, take place in anonymized, aggregated, pseudonymized, or abstracted form.
(5) KnowFab is entitled to reuse general technical knowledge, methods, experience, non-customer-specific know-how, and generic improvements, provided that no confidential information of the customer is disclosed.

(7) Where statutory requirements regarding access to or use of data, in particular from connected products, machines, equipment, or related services, are relevant, the parties will regulate the resulting rights and obligations separately if this is necessary for the provision of services.
§8 AI Systems, Analysis Results, and Regulatory Classification
(1) The models and software solutions provided by KnowFab deliver analysis, assessment, or prediction results based on the respective data, parameters, model versions, and system environments provided.
(2) The accuracy, stability, and informative value of the results depend materially on the quality, completeness, representativeness, and up-to-dateness of the input data and on the specific operating environment.
(3) KnowFab does not guarantee error-free detection, assessment, or prediction of all process, quality, product, or equipment states unless a specific characteristic, inspection accuracy, model quality, performance metric, or concrete field of use has been expressly agreed.
(4) The provided systems serve technical analysis and decision support. They do not replace professional review, an approval decision, validation of the production process, or any legally, regulatorily, or normatively required review by the customer.
(5) Use of the software for automated approval, blocking, control, or safety-relevant assessment of products, components, equipment, or processes is permitted only if this has been expressly contractually agreed and technically approved.
(6) In particular, KnowFab does not approve components, processes, products, equipment, inspection processes, or series launches unless this has been expressly agreed.
(7) If a service may be classified under applicable law as a regulated AI system, high-risk AI system, safety component, product with digital elements, or comparable regulated component, the parties will define the respective role, responsibility, documentation obligations, inspection obligations, information obligations, and cooperation obligations separately in the offer or in an additional agreement.
(8) The customer is obliged to inform KnowFab in advance if the software, a model, or a result from KnowFab is to be used in a safety-relevant, regulated, approval-requiring, or product-critical context.
§9 Training, Customization, and Use by the Customer
(1) To the extent the customer is enabled to train, configure, modify, customize, or operate models with its own parameters, this is done exclusively at the customer's responsibility unless a more extensive responsibility of KnowFab has been expressly agreed.
(2) The customer is responsible for professional review, validation, and monitoring of such customizations.

(1) For SaaS services, KnowFab provides the customer with the agreed software or functionality via a technical environment. Details are set out in the offer or service description.
(2) For license models, the customer receives the rights of use to the software or models agreed in the offer. Source code is provided only if this has been expressly agreed.
(3) For on-premise installations, the customer is responsible for operation, maintenance, security, backup, infrastructure, networks, servers, access rights, system environment, and compliance with internal IT requirements unless expressly agreed otherwise.
(4) In the case of integration into customer systems, KnowFab's service is limited to providing the agreed models, interfaces, documentation, or support services unless further integration, operation, or maintenance services have been expressly agreed.
(5) KnowFab is not liable for errors, disruptions, outages, or security incidents resulting from the customer's system environment, third-party interfaces, changes by the customer, or components not controlled by KnowFab.
(6) The customer is obliged to carry out appropriate tests in a suitable test environment before productive use.
(7) Productive use in safety-critical, series-relevant, or approval-relevant processes requires express approval in the respective project.

(2) KnowFab will provide the service to the customer for acceptance after completion.
(3) The customer is obliged to inspect the service within 10 working days after provision and either declare acceptance or report material defects in a comprehensible form.
(4) If no acceptance and no material defect notice is issued within this period, the service is deemed accepted, provided KnowFab informed the customer of this consequence when providing the service.
(5) Immaterial defects do not entitle the customer to refuse acceptance.
(6) Change requests, extensions, or optimizations that go beyond the agreed scope of services do not constitute defects and must be agreed separately.
§12 Rights of Use and Intellectual Property
(1) All rights to pre-existing software, base models, algorithms, methods, concepts, frameworks, libraries, interfaces, documentation, workflows, data structures, and technical know-how of KnowFab remain with KnowFab.
(2) The customer receives a simple, non-exclusive, non-transferable right to use the contractually provided services within the agreed scope and for the agreed term, unless otherwise regulated in the offer.
(3) The customer may use project results, reports, evaluations, customer-specific parameterizations, configurations, or documentation within the agreed contractual purpose, unless otherwise regulated in the offer.
(4) Customer-specific customizations do not cause rights to underlying base models, algorithms, methods, software components, or know-how of KnowFab to transfer to the customer.
(5) The customer is not entitled to use, reproduce, modify, rent, lend, make publicly available, reverse engineer, decompile, or use KnowFab software, models, interfaces, or documentation for the development of competing systems outside the agreed scope of use, unless this is mandatorily permitted by law.
(6) Rights to data, documents, specifications, drawings, process information, or other materials provided by the customer remain with the customer.

§13 Term and Termination
(1) The term is determined by the respective offer or agreement.
(2) Recurring services, in particular SaaS, license, maintenance, or support contracts, automatically renew for the respectively agreed term unless terminated in text form with a notice period of 3 months before the end of the term.
(3) Automatic renewal does not apply to one-time project services, consulting services, feasibility studies, pilot projects, or other individual services unless expressly agreed otherwise.
(4) The right to extraordinary termination for good cause remains unaffected.
