Tuning tool purchases once activated or registered
Software credits and file service credits
Any electronically delivered product or access key
Training course fees (online and in-person)

Contact USA@Viezu.com — Subject: Support Request — [Order Number]. We respond within 2 business days.

8.7 Chargebacks

Please contact us before initiating a chargeback. We maintain full records of all transactions and delivery confirmations. Fraudulent or unwarranted chargebacks will be disputed and may result in account suspension or reporting to payment processors.

8.8 Hardware Manufacturer Warranty

Physical tuning tools sold by Viezu USA are covered by the warranty provided by their respective manufacturers (Alientech, Autotuner, Magic Motorsport, and others as applicable). As a reseller, Viezu USA passes through the manufacturer's warranty to you but does not provide an independent warranty on physical hardware beyond what the manufacturer offers.

To initiate a warranty claim, contact us at USA@Viezu.com with your order number and a description of the issue. We will coordinate with the manufacturer on your behalf. Warranty claims are subject to the manufacturer's terms, including requirements regarding proof of purchase, claim timelines, and acceptable defect conditions.

Warranty coverage does not extend to damage caused by misuse, improper installation, unauthorized modification, or use inconsistent with the manufacturer's instructions.

9. Off-Road Use and Emissions Compliance

9.1 Certain products and services we offer — including DPF (Diesel Particulate Filter) removal files, EGR (Exhaust Gas Recirculation) delete files, and associated tuning calibrations — are sold exclusively for off-road and closed-course competition use only. These products are not intended for use on vehicles registered for or operated on public roads.

9.2 Installation of emissions-modification software or hardware on a road-registered vehicle may violate the federal Clean Air Act (42 U.S.C. § 7401 et seq.), applicable state emissions laws, and any regulations set by your state's Department of Motor Vehicles or equivalent authority. Some states, including California, have more stringent vehicle emissions requirements than federal law.

9.3 By purchasing any emissions-related product or service from us, you represent and warrant that:

The vehicle on which the product will be used is not registered for, or operated on, public roads; or
You have independently confirmed with qualified legal counsel that installation of the product on your specific vehicle is lawful in your jurisdiction.

9.4 Viezu USA is not responsible for, and expressly disclaims all liability in connection with:

Federal, state, or local fines or penalties arising from the installation or use of emissions-modification products
Failed emissions inspections
Voiding of any vehicle manufacturer warranty
Civil or criminal liability arising from non-compliant use

9.5 Performance tuning results — including horsepower, torque, and fuel economy claims — are estimates based on typical outcomes with stock vehicles. Actual results vary based on vehicle condition, fuel quality, ambient conditions, and other factors. All performance tuning is performed at the buyer's risk.

10. Software License

10.1 Upon purchase of any software, software license, or digital tuning file, we grant you a limited, non-exclusive, non-transferable license to use that software solely for your own personal or internal business purposes, as applicable.

10.2 You do not acquire any ownership rights in the software. You are licensed to use it, not to own it. You have no right to access the source code.

10.3 Your license permits use of the software on compatible hardware that you own or control. You may make one backup copy for archival purposes only.

10.4 The following are strictly prohibited:

Copying, reproducing, or distributing the software beyond a single backup copy
Reselling, sub-licensing, renting, leasing, or lending the software to any third party
Modifying, reverse engineering, decompiling, or disassembling the software
Combining the software with other programs in a way that circumvents its license restrictions
Removing or obscuring any copyright, trademark, or proprietary notices
Distributing tuning files, calibrations, or any outputs derived from licensed software to unauthorized parties

10.5 Your license may be terminated immediately and without notice if you breach any of these terms. Upon termination, you must cease all use of the software and destroy all copies in your possession.
