Privacy
Your data stays on your device. Below is the full breakdown of what the app collects, what goes where, and what we don't touch.
What stays on your device
The following is stored locally and never leaves your phone unless you explicitly export or share it:
- Trip recordings: GPS tracks and OBD telemetry (speed, temps, boost, etc.) captured while a trip is active
- Build log: parts, install notes, and photos you add to your vehicle profile
- Vehicle information: name, model year, color, and VIN (read from your truck's OBD port)
- Backups: parameter snapshots taken before a mod is applied
- App preferences: theme, units, alert cooldown settings
What leaves your device
Crash reports
When the app crashes, an anonymous crash report is sent to Sentry (sentry.io). The report contains:
- Stack trace (the code path that caused the crash)
- Device model and iOS version
- App version and build number
- BLE connection state at the time of the crash (connected or disconnected)
- Truck generation (e.g. Gen 3)
Never included: your identity, VIN, OBD sensor readings, GPS coordinates, trip data, or anything that could identify you. See Sentry's privacy policy for details.
In-app purchase
Purchase and entitlement status is verified through RevenueCat. RevenueCat receives your App Store receipt and entitlement status. See RevenueCat's privacy policy for details.
Product links
The Build tab contains Amazon product links. These include an Associates referral tag
(chasebaja-20), which means a small commission may apply on qualifying purchases.
A disclosure is shown on screen when these links are present. Amazon's
privacy policy
applies once you leave the app.
