What the app does, where its data comes from and what it deliberately does not claim.
You describe the symptom, upload photos or answer the guided questions. AutoAid matches what you report against a curated library of common car and motorcycle fault patterns, then ranks the likely causes with a confidence score. It is pattern matching over your answers — not a mechanic, and not a scan of your vehicle's ECU.
Registration lookup uses the official DVSA MOT History API. Make, model, fuel type, engine size, last recorded mileage, MOT expiry and every advisory or failure item come straight from government records. Nothing about your vehicle is invented — if DVSA has no record, AutoAid tells you so rather than guessing.
Cost figures are indicative UK reference ranges: a fixed parts range per repair, multiplied by a typical labour time, at a regional labour rate band derived from your postcode. They are not live quotes and not sourced from garages near you. Treat them as a sanity check on a quote, not a price you are owed.
Your vehicles, diagnoses and photos stay on this device — there is no account and nothing is uploaded to a server. AutoAid never gives a guarantee: urgency ratings are guidance, and anything safety-critical (brakes, steering, tyres, fuel leaks) should be inspected by a qualified mechanic before you drive.
MOT data is provided by the Driver and Vehicle Standards Agency under the Open Government Licence. AutoAid is an independent tool and is not affiliated with DVSA or DVLA.
