Terms of use

These terms govern access to Crazy Tuner’s websites, software, and AI-assisted tuning features. By creating an account or using paid plans (DIY report packs or shop subscriptions), you agree to the fees, acceptable use rules, and disclaimers in the full agreement below. Crazy Tuner provides guidance and diagnostics only—you remain responsible for safe operation of the vehicle and compliance with applicable laws.

Credits, refunds, subscription changes, and intellectual property are defined in the embedded terms. For questions about billing or enterprise agreements, contact sales.

Outputs are advisory: you decide what to change in calibration or hardware. Racing, emissions, and road-use compliance remain your obligation. If you use Crazy Tuner in a commercial shop, your customer agreements and liability insurance should reflect that software-assisted diagnostics do not replace professional judgment or manufacturer guidance.
