Trademark, independence and liability notice

QNTUM21 is an independent provider of automotive software. QNTUM21 is not economically, legally or organisationally affiliated with Bayerische Motoren Werke Aktiengesellschaft (BMW AG) or any of its affiliated companies. QNTUM21 and its products are not authorised, certified, endorsed or sponsored by these companies.

Vehicle brands and product designations: BMW, MINI, Rolls-Royce, BMW M, M3, xDrive, iDrive and other manufacturer, brand, model, series and equipment designations are trademarks, product names or other protected signs of their respective owners. They are mentioned solely where necessary to identify vehicles, control units, technical relationships, compatibility or the intended use of QNTUM21 products. All Q21 products are independent products of QNTUM21 and are not products of BMW AG or any other vehicle manufacturer.

Suppliers and platform providers: ZF is a trademark or company designation of ZF Friedrichshafen AG. Apple, App Store and TestFlight are trademarks or service marks of Apple Inc. iOS is a trademark or registered trademark of Cisco in the United States and other countries and is used under licence by Apple. Android and Google Play are trademarks of Google LLC. Microsoft, Windows and Microsoft Store are trademarks of the Microsoft group of companies. These names are used solely to describe installed components, supported operating systems or intended distribution platforms. No authorisation, certification, endorsement, sponsorship or other commercial affiliation exists unless expressly stated otherwise.

Technical designations: ZGW, DS2, KWP2000, CAN, D-CAN, PT-CAN, K-CAN, ENET and comparable abbreviations are used solely as technical system, control-unit, network or protocol designations. Their use does not claim rights in those names and does not imply manufacturer approval or an official technical partnership. All trademarks and other protected signs remain the property of their respective owners.

A statement of technical compatibility does not constitute approval, homologation, road authorisation, guarantee or warranty by the vehicle manufacturer. Only the specific QNTUM21 product description, vehicle-specific approval and agreed contractual terms are authoritative.

Technical content is prepared with care but may become outdated due to changes in vehicles, software or law. It does not replace a vehicle-specific inspection, diagnosis, approval or clearance by qualified professionals or competent authorities. Before modifying a vehicle or its software, users must verify legal admissibility, operating approval, emissions and noise requirements, insurance cover and possible effects on manufacturer or seller rights. Mandatory statutory liability remains unaffected; the liability provisions in our Terms of Use also apply.
