01Company Identity & Applicability

  • The contractual partner for all services provided through this website is RazTech Automotive Electronic Solutions, owned and operated by Silviu-Razvan Tosa (Inhaber: Silviu-Razvan Tosa), located at Haart 81 Apt 3.1, 24534 Neumünster, Germany ("RazTech").
  • RazTech Automotive Electronic Solutions operates the website and client portal through which professional vehicle tuners purchase custom ECU calibration files and related digital services.
  • The legal relationship and every agreement between RazTech and the Client are governed exclusively by these Terms & Conditions, unless otherwise agreed in a written agreement.
  • These Terms apply to all offers, orders, and distance contracts concluded through the RazTech website and client portal. By ordering or purchasing any service, the Client confirms that they have read and accepted these Terms.
  • RazTech reserves the right to modify these Terms at any time. Any changes take effect upon publication on this page. Orders already confirmed remain governed by the Terms in force at the time of confirmation.

02Definitions

  • Client: the natural or legal person acting in a professional capacity who enters into a distance agreement with RazTech for the supply of calibration files or related services.
  • Distance Agreement: any agreement concluded entirely through the RazTech website or client portal, without the Client and RazTech being present in the same location.
  • Credit / Token: a prepaid unit of value held in the Client's wallet, used to pay for individual calibration files or services.
  • Calibration File: the custom electronic file containing modified vehicle management software, created specifically per Client order.
  • Reflection Period: the period during which a consumer Client may exercise the right of withdrawal.
  • Right of Withdrawal: the right of a consumer Client to terminate the distance agreement within the reflection period without stating reasons, where applicable.

03Product & Delivery

  • RazTech develops custom vehicle management software in the form of an electronic file created specifically per Client order. Once the order is confirmed and the required credits are debited, the file is engineered to the Client's specifications.
  • Standard calibration files are delivered under 1 hour during operating hours. Files submitted outside operating hours are processed at the start of the next working day.
  • After a file has been processed and paid for, it is made available for download in the Client's account. Every purchased digital file remains available for download for thirty (30) days from the delivery date.
  • An invoice is generated and made available immediately after payment and product delivery.
  • If a submitted file cannot be calibrated for technical reasons, the credits debited for that request are returned to the Client's wallet automatically.

04Clients — B2B Exclusively

  • Given the highly specific nature of the Products, RazTech supplies its services exclusively in a B2B arrangement to professional vehicle tuners who are sufficiently trained, educated, and skilled in the tuning of vehicles and who can tune a vehicle without education or assistance from any third party.
  • By ordering or purchasing RazTech products, the Client confirms that they are a professional vehicle tuner with previous training and extensive knowledge of the vehicle tuning process.
  • The services and products offered on this website are intended for use by professional and experienced vehicle tuners only. To access the service, the Client must be a registered user.
  • If the Client is under the age of eighteen (18) or under the legal age in their country, they are not permitted to register as a user or to provide RazTech with any personal information.

05Software Usage Terms

  • All calibration files supplied by RazTech are custom software modifications intended for the Client's specified vehicle and ECU only.
  • Files are licensed, not sold. The Client receives a non-exclusive, non-transferable right to flash the supplied file onto the single vehicle it was calibrated for.
  • Reverse-engineering, reselling, redistributing, or re-using a delivered file on a different vehicle is strictly prohibited.
  • The Client is responsible for ensuring they have the legal right to modify the ECU of the vehicle they submit.

06Track-Use Disclaimer — Emissions Deactivations

Emissions-related deactivations are for track/off-road use only and may not be road-legal in your jurisdiction.

  • DPF, EGR, SCR/AdBlue, and Vmax deactivation services are supplied strictly for track, off-road, motorsport, or private-estate use only.
  • These modifications may render a vehicle non-compliant with emissions regulations in the Client's jurisdiction and may be illegal for road use.
  • RazTech accepts no liability for any road use of a vehicle modified with an emissions-related deactivation.
  • The Client assumes full legal responsibility for the road use of any deactivated vehicle and confirms the vehicle will not be used on public roads in a non-compliant state.
  • By purchasing a deactivation service, the Client confirms they have read and accepted this disclaimer.

07Right of Withdrawal & Exceptions

  • When purchasing products, a consumer Client residing in the European Union (EU) or European Economic Area (EEA) has the right to terminate the agreement within 14 days without stating reasons. This reflection period starts on the day of receipt of the product by the Client.
  • The 14-day right of withdrawal does not apply to digital content and credits. By purchasing tuning credits, the Client explicitly consents to the immediate performance of the contract and acknowledges that they lose the right of withdrawal once the credits are credited to the account or performance has begun.
  • The 14-day right of withdrawal does not apply to customized hardware or activated protocols — flashing tools, interfaces, or hardware devices that have been activated, bound to a user profile, or updated with specific protocols or firmware according to Client specifications, as these constitute personalized goods.
  • For all standard, non-activated hardware devices and physical accessories, the standard 14-day right of withdrawal remains valid.
  • For Clients residing outside the EU/EEA, all sales are final and no right of withdrawal applies unless required by mandatory local law.

08Refunds — No-Refund Policy for Digital Services

  • When ordering custom tuning files and solutions, Clients are charged for the work performed by RazTech engineers, rather than the outcomes of that work. RazTech is committed to delivering a quality product and offering comprehensive support. All labor must be compensated, and therefore no refunds — partial or full — are offered for software modifications and solutions.
  • By confirming this no-refund policy for custom-made digital products, the Client agrees to waive their right of withdrawal for digital content.
  • In rare cases where a solution cannot be achieved, RazTech will return digital credits of equivalent value to the Client's wallet, which can be used for future services.
  • Unused token credit packs may be refunded within 14 days of purchase, less payment-processing fees, provided the credits have not been used.

09Limited Warranty

  • RazTech warrants that delivered files are free from defects in the calibration maps at the time of delivery. If a fault exists within the software and can be identified as due to a specific issue inherent to the supplied calibration, RazTech offers a limited warranty: if reported within 30 days after delivery, RazTech will provide revised software to resolve the fault.
  • To claim warranty, the Client must report software issues exclusively through their user account and the purchased project page, so that identity and ownership of the file can be verified.
  • The warranty does not apply where a vehicle fault is due to the Client not providing correct vehicle details, additional hardware being fitted, an improperly maintained vehicle, any modification of the supplied product by a third party, or wrong installation procedures. The implementation of the tuning software in the vehicle is at the sole risk of the Client and is excluded from the warranty.
  • The Client may be required to follow reasonable steps to provide RazTech with adequate data in order to make an informed judgement for a satisfactory resolution. Failure to provide the requested information, or access to the vehicle, may lead to no further support being offered, at RazTech's sole discretion, and a refund will be refused.
  • The Client agrees that they will not make any representation nor give any warranties to the owner of a vehicle tuned other than those in relation to the Product itself.

10Limitation of Liability & Indemnification

  • The Client acknowledges and accepts that RazTech shall not be held liable for any indirect, incidental, consequential, or similar damages or losses incurred by the Client. This includes, but is not limited to, financial and commercial prejudice, loss of profit, loss of sales, increased costs and overhead, loss of clientele or image, disruption to the Client's business planning, or loss of data, files, or computer programs resulting from the use or inability to use the Products.
  • Without prejudice to mandatory statutory provisions, RazTech's liability shall strictly be limited to the price of the relevant software or digital credits purchased. In no event shall RazTech be liable for damages incurred by the end-user (the owner of a vehicle tuned by the Client).
  • RazTech explicitly disclaims liability for damages caused by incompetent use of the products or use for a purpose other than that for which they are objectively intended; damages caused by materials or services provided by third parties without prior written consent; any direct or indirect damages resulting from improper actions, carelessness, negligence, or improper maintenance of the products by the Client; and normal wear and tear of the products.
  • Indemnification: the Client agrees to fully indemnify, defend, and hold harmless RazTech against all liabilities, costs, expenses, damages, and losses (including legal fees) arising out of or in connection with any claim made by a third party related to the supply or use of the Products, to the extent that such claim is attributable to the acts, omissions, or modifications performed by the Client, their employees, agents, or subcontractors.

11Intellectual Property Rights

  • The Products, services, content, and all parts of the RazTech website (including all trademarks, logos, designs, drawings, data, product and company names, texts, images, and software) are protected by intellectual property rights belonging to RazTech or third parties with RazTech's authorization.
  • The Client is not entitled, for any reason, to modify, copy, distribute, send, re-offer, reproduce, publish, assign under license, transfer, or sell, or to create derivative works from, any of the aforementioned elements. The supply of products or services by RazTech does not imply any transfer of its intellectual property rights.
  • The software offered by RazTech remains the exclusive property of RazTech. Upon termination of the use of the software, the Client will destroy all software applications, together with the related documentation and manuals. The Client undertakes to keep the software confidential.
  • Any breach of RazTech's intellectual property rights may lead to civil and criminal proceedings in accordance with applicable legislation.

12Payment & Credits

  • RazTech uses a prepaid credit system. Credits are purchased in advance and credited to the Client's account, then debited automatically when a file service request is submitted.
  • Credits remain valid as long as the account is active and do not expire after a certain period. Larger credit packs offer a lower per-file cost.
  • When an account is removed, any credits remaining in the account are also cancelled. Refund of unused credits is not possible, except as stated in Article 8.
  • RazTech may modify pricing and pack structures with reasonable notice. Existing credit balances are honored at their purchased value.
  • According to § 19 UStG (Small Business Regulation / Kleinunternehmerregelung), no Value Added Tax (VAT / Umsatzsteuer) is charged or displayed on invoices.

13Complaints & Disputes

  • RazTech maintains a published complaints procedure and will deal with any complaint in accordance with this procedure.
  • In the event of any complaint about the execution of the agreement, the Client will notify RazTech of the complaint within 7 days after the complaint arises, clearly and fully detailed and in writing.
  • RazTech will act on any complaint within 14 days from the date of receipt. If handling the complaint will take longer, RazTech will notify the Client within that 14-day period and provide an indication of when a more extensive answer can be expected.
  • If a complaint cannot be solved to mutual satisfaction, the Client will first turn to RazTech. If the matter remains unresolved, the Client may seek mediation before pursuing binding dispute resolution.
  • A complaint shall not suspend the obligations of RazTech or the Client, unless RazTech states otherwise in writing.

14Governing Law & Jurisdiction

  • These Terms are governed by the laws of the Federal Republic of Germany.
  • Any disputes shall be resolved in the courts of Germany, without prejudice to the Client's statutory consumer rights where applicable.
