Privacy Policy for Tacograph: Speed Alert
Effective Date: March 17, 2026
1. Introduction Welcome to Tacograph: Speed Alert (“we,” “our,” or “us”). We are committed to protecting your privacy. This Privacy Policy explains how our application collects, uses, and safeguards your information when you use our mobile application.
2. Background Location Data (Prominent Disclosure) Tacograph: Speed Alert relies on GPS data to function as intended. We collect location data to calculate your vehicle’s real-time speed and display the floating speed widget (overlay) over your navigation apps (like Waze or Google Maps), even when the app is closed or not in use. This background location tracking is strictly used for the core functionality of the speedometer and the 60-second tolerance timer.
3. Data Storage and Privacy We respect your privacy. We do not transmit, store on external servers, or sell your location data. All speed tracking and location calculations are processed locally on your device in real-time. The “History” feature (infraction log) saves data locally on your phone’s internal storage. You have full control over this data and can delete it at any time directly within the app.
4. Third-Party Services and Advertising To keep the app free, we use Google AdMob to display advertisements. AdMob may collect and use certain data (such as advertising IDs and generic device information) to provide targeted ads. We do not share your location data with AdMob. For more information on how Google uses this data, please review the Google Privacy & Terms. We also use the Google Play In-App Review API, which interacts with Google Play Services to request user ratings.
5. Permissions Required To use the app, you must grant the following permissions:
Location Permissions (Foreground & Background): Required to calculate speed via GPS.
Display Over Other Apps (Overlay): Required to show the floating speed widget on top of your GPS navigation apps.
Notifications: Required by Android to keep the background service running reliably.
6. Disclaimer Tacograph: Speed Alert is a driving aid based on GPS hardware. It does not replace the official tachograph or the vehicle’s speedometer. We are not responsible for any traffic fines, infractions, or damages resulting from the use of this application. Always obey local traffic laws.
