COMPATIBILITY:
Works with ELM327 OBD2 adapters (Bluetooth & WiFi). Supports OBD2-compliant
vehicles (generally fuel-injected cars from 2008 onward; some earlier).
Clean Material Design interface, English & Indonesian, dark mode, metric
and imperial units.
PRIVACY:
Your vehicle diagnostic data stays on your device. We run no server and
require no account. Only two things leave your device: anonymous usage
statistics (which features get used), which you can switch off at any time
in Settings, and an anonymous crash report (Firebase) if the app stops
unexpectedly — it contains the error details, device model, Android version,
app version and the type of adapter in use. Your diagnostic data, trouble
codes, VIN and location are never included. CSV exports and PDF reports are
created only when you ask, and shared only if you choose to.
IMPORTANT: This app is for diagnostic purposes. Do not use while driving.
The performance test carries risk, is for closed or private tracks only,
and is entirely the user's responsibility.
