Your vehicle list, saved reports, and preferences are stored locally on your device. To create a diagnosis, the app sends the vehicle details, problem description, and any photo you add to OpenAI, a third-party AI provider in the United States, which uses it only to generate your result and does not use it to train its models. To power specific features we also share limited data with other services — your location with OpenStreetMap to find nearby shops, your vehicle and VIN with NHTSA for safety recalls, and your vehicle and problem with YouTube and Reddit for repair videos and community advice. We ask for your permission inside the app before sending anything to our AI service the first time, and you can decline. We do not sell your data. See our Privacy Policy for full details.

Please email us with a short description and a screenshot if possible. We read every message.
No. Dummy Mechanic AI is an AI assistant that helps you understand likely causes and next steps. For safety-critical issues (brakes, steering, structural damage) always have a licensed mechanic inspect your vehicle.
