The short version: Lemonscope has no account, no analytics and no tracking. Sensor data, your route, photos and reports stay on your iPhone. The only data that leaves the device is a VIN (and the make, model and year it decodes to), sent to the U.S. government's public NHTSA services to look up the vehicle, recalls and complaints.
Who we are
Lemonscope ("the app", "we") is an iOS app that helps used-car buyers screen a car during a test drive. It is an indicative screening tool, not a professional mechanical inspection.
Data the app uses
Motion sensor data: accelerometer and gyroscope readings during a test drive, used to measure idle vibration, suspension bounce, braking, tracking and gear shifts. Processed on your device and not stored after analysis; only the results are saved.
Location: used only while the drive screen is open (when-in-use), to find straight stretches and braking events. It is not uploaded or shared.
Microphone (optional): if you turn on cabin-noise measurement, the app reads the sound level only. No audio is recorded or saved.
Camera and photos: used to scan a VIN and, if you choose, to attach photos to checklist items. Photos are stored in the app on your device.
Vehicle lookups: the VIN you enter is sent to NHTSA's vPIC API, and the decoded make, model and year to NHTSA's Recalls and Complaints APIs. These are public U.S. government services and receive no personal information from us. See NHTSA's privacy policy.
Purchases: Inspector Pro is handled entirely by Apple's App Store. We never see your payment details.
What we don't do
We don't use analytics, advertising or tracking SDKs, we don't have servers that receive your data, and we don't sell or share personal data.
Your choices
Grant or revoke motion, location, camera and microphone access at any time in iOS Settings.
Delete any inspection by long-pressing it on the home screen, or everything from About in the app. Deleting the app removes all its data.
Children
Lemonscope is not directed at children under 13 and does not knowingly collect their data.
Changes
We may update this policy. Material changes will be reflected in the "Last updated" date above.
