Privacy Policy

Effective 11 June 2026 · ApplianceDoc ("the app")

Sensor data stays on your device

Vibration (accelerometer) and audio (microphone) recordings captured during a scan are processed entirely on your iPhone. Raw sensor data is never uploaded, transmitted, or shared. Diagnostic results and scan history are stored locally on your device.

Account information

If you create an account, we use Firebase Authentication (Google LLC) to manage sign-in. Depending on the method you choose, Firebase processes your email address, display name, and a unique user identifier (for Sign in with Apple, Apple may provide a private relay email). We use this solely to authenticate you. See Firebase's privacy documentation.

Purchases

Subscriptions and one-time purchases are processed by Apple. We do not receive or store your payment details.

On-device intelligence

AI-generated explanations and the "Ask the Mechanic" chat run on-device using Apple's Foundation Models. Your questions and scan data are not sent to any server.

Analytics and tracking

The app contains no third-party analytics or advertising SDKs and does not track you across apps or websites.

Data deletion

Deleting the app removes all local scan data. To delete your authentication record, email anandraj.sengupta@icloud.com.
