Get help or report a problem

In the app: Settings → App Info → Send Feedback. Pick Bug, Idea, or Question, describe what happened, and attach a screenshot if it helps. Feedback reaches us through our diagnostics provider; include an email address if you want a reply.
Turn on Share diagnostics in Settings → Privacy first; the feedback form uses it.

VIN won't scan. Try the barcode on the door jamb or type the VIN in manually; the check digit is validated as you type.
Decoded details look wrong. They come from the U.S. NHTSA vPIC service. Edit any field in the vehicle's form; your edits win.
Recalls. Matched by make, model, and year, so some may not apply to your exact vehicle. Confirm at nhtsa.gov.
Where is my data? On your device and in your private iCloud. Garages you share travel through Apple's iCloud sharing to the people you invite. VINs go to NHTSA for decoding, diagnostics go to Sentry if Share diagnostics is on, and an AI assistant you allow reads it through our connector (see the Privacy Policy). Export a full backup from Settings → Data.
Shared garages. Share a garage from the Garage tab. Everyone you invite sees the garage's vehicles, and you choose whether identifiers, money, documents, and custom fields go with them. People you share with can use their own AI assistant on what you share with them.
AI assistant. Optional, and off until you allow it. Open Settings → AI Assistant: it lists what an assistant can read and which company receives it. Tap Allow, then tap Setup steps for Claude, ChatGPT, Grok, and others on the same screen. The assistant reads your collection live from your iCloud through our connector, which keeps no copy of it; the assistant's maker receives what it reads. Turn off AI assistant access there at any time.
