CargoLog — Truck Driver Logbook · Last updated: April 28, 2026

CargoLog ("the App") is a truck driver logbook application developed by German ("Developer", "we", "us"). This Privacy Policy explains what data the App collects, how it is used, and your rights regarding that data.

1. Data We Collect

Data type	Purpose	Stored where
Trip records (origin, destination, odometer, cargo details, timestamps)	Core logbook functionality	On-device only
Vehicle and trailer information (plate numbers, type, year)	Garage management	On-device only
Refueling records	Fuel tracking and reports	On-device only
Driver name	Display in app header and reports	On-device only
Camera images (container numbers, cargo photos)	OCR recognition of container/seal numbers, trip documentation	On-device only
Location (precise, approximate, background)	Determining trip origin/destination; future GPS tracking feature	On-device only
App usage analytics	Understanding app usage patterns to improve the product	Google servers (Firebase Analytics)
Crash reports	Identifying and fixing bugs	Google servers (Firebase Crashlytics)

2. Data That Stays on Your Device

All trip data, vehicle profiles, trailer information, refueling records, driver name, and photos are stored exclusively in a local database on your device. We do not transmit this data to any server. The App does not have user accounts, cloud sync, or remote storage. You can export your database manually via the Settings screen.

3. Third-Party Services

The App uses the following third-party services that may collect data:

• Firebase Analytics (Google) — collects anonymous app usage data such as screen views, session duration, device model, and OS version. No personally identifiable information is sent. Firebase Privacy.
• Firebase Crashlytics (Google) — collects crash reports including stack traces, device model, OS version, and app state at the time of crash. No personal data from your logbook is included. Firebase Privacy.
• Google ML Kit (on-device) — used for text recognition (OCR) of container numbers. All processing happens on-device; no images or text are sent to Google servers.
• Google Play In-App Updates — checks for app updates via the Google Play Store.

4. Permissions

Permission	Why we need it
Camera	Scanning container/seal numbers (OCR) and taking cargo photos
Fine / Coarse Location	Auto-filling trip origin and destination
Background Location	Future GPS tracking feature (not active by default)
Internet	Firebase Analytics, Crashlytics, and checking for app updates
Notifications	Timer notifications (waiting time, refueling, at client, unloading)
Vibration	Haptic feedback for OCR container number validation
Foreground Service	Running timers while the app is in background

5. Data Sharing

We do not sell, trade, or rent your personal data to third parties. We do not share your logbook data with anyone. The only data transmitted from the App is anonymous analytics and crash reports sent to Google Firebase, as described in Section 3.

6. Data Retention and Deletion

All logbook data is stored on your device and persists until you delete it. You can:

• Delete individual trips from the trip history screen.
• Delete vehicles and trailers from the garage screen.
• Export or clear the entire database via Settings.
• Uninstall the App to remove all locally stored data.

Firebase Analytics and Crashlytics data is retained according to Google's data retention policies.

7. Children's Privacy

The App is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can take appropriate action.

8. Your Rights

Depending on your location, you may have rights under applicable data protection laws (such as GDPR or CCPA), including the right to access, correct, or delete your personal data. Since all logbook data is stored locally on your device and we have no access to it, you have full control over your data at all times.

For data collected by Firebase, you can opt out by disabling analytics collection or by contacting us to request deletion.

9. Security

Your logbook data is protected by your device's built-in security (screen lock, encryption). The App does not transmit your logbook data over the internet. Network communications with Firebase services use encrypted HTTPS connections.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the App after changes constitutes acceptance of the revised policy.
