Effective date: 21 October 2026
This policy explains how Speedometer: GPS Speed & Trip for Android (the “app”, “we”) handles your information. The app uses your location on your phone to show your speed, distance and route, and your location, trips and settings stay on your phone unless you choose to share them. To find and fix problems, the app sends Google Firebase usage statistics and crash reports that are not linked to your name or any account, and are not intended to include your location, speeds or trips.
The app is published by DevsGround. If you have any questions, contact us at devsground.help@gmail.com.
Your Location
The app needs access to your precise location to work as a speedometer. It reads GPS positions from your phone and uses them, on your device, to:
- Show your current speed, distance, altitude, direction of travel and GPS signal details.
- Warn you when you go over the speed limit you set.
- Record trips and draw their route, if you start a trip and have Save Tracking Data turned on.
Your location is not uploaded by the app and is not intentionally sent to DevsGround, Firebase or other third parties. The app only asks for location access while the app is in use. It does not ask for “Allow all the time”. When you start a trip, tracking can continue with the screen off or while you use other apps; Android displays a notification while this is active, and you can stop the trip from that notification.
What Is Stored on Your Device
The app stores the following information on your phone:
- Saved trips: start and end time, duration, distance, maximum and average speed, vehicle type, and the route as a list of GPS points (latitude, longitude, time and speed).
- Odometers: total distance travelled for each vehicle type.
- Settings: preferences such as units, speed limits, alert sound and vibration, theme, accent colour and the position of the floating speed window.
You can delete saved trips in the app at any time and turn off Save Tracking Data in Settings so trips are not stored. Clearing the app's data in Android settings or uninstalling the app removes locally stored app data, subject to Android device and backup behavior.
What We Collect
There are no accounts and no advertising, and we do not sell personal information. Your location, speeds, trips, routes and settings stay on your phone unless you choose to share them.
To help keep the app working well, it uses these Google Firebase services, which Google provides under its Firebase privacy information:
- Firebase Analytics: may process usage statistics such as screens opened, app interactions, usage duration, Google Play install-referrer information, app version, device model, Android version, language and approximate region inferred from IP address rather than GPS. It uses an app-instance identifier. The app does not use the advertising ID, and this information is not used by the app for advertising or ad personalization.
- Firebase Crashlytics: when the app crashes, it may send technical details such as crash information, app version, device model, Android version, available memory and storage, and an installation or app identifier. The app is designed not to include your location, speeds or trips in crash reports.
- Firebase Cloud Messaging: may be used to send occasional app-related messages, for example about new features. A messaging token is processed to deliver messages to your installation. You can turn off app notifications in Android settings.
Google Analytics data retention can be configured and may be up to 14 months depending on settings. Crash-report retention may depend on the service settings and Google's practices. We use this information to understand general app usage, diagnose technical problems and improve reliability. Data is transmitted over encrypted connections such as HTTPS, and Google may process it on servers outside your country under its applicable safeguards. For more information, see Google's Privacy Policy.
Other Internet Features and External Services
- More Apps: the app may download a public list of our other apps and their icons from GitHub at
raw.githubusercontent.com. GitHub may receive technical information such as your device's IP address. The app does not include your location or trip data in this request. - App updates and ratings: the app may check for updates or show Google Play's in-app review prompt. These features operate through Google Play under Google's privacy practices.
- External links: links for the privacy policy, Play Store, email, Telegram and WhatsApp open in the apps or services you choose. Their own privacy policies apply when you use them.
Your Choices and Data Deletion
- Location: you can withdraw location permission in Android settings. Without it, the app cannot measure speed.
- Trips: delete trips from History or turn off Save Tracking Data in Settings.
- Messages: turn off the app's notifications in Android notification settings.
- Statistics and crash reports: clearing app data or uninstalling may reset app or installation identifiers. This does not necessarily delete information already held by Google services.
- Deletion requests: email devsground.help@gmail.com to ask about data held by service providers. Because the app does not ask you for a name or account, we may need relevant details, such as your phone model and the approximate date of a crash, to investigate a request. We may not be able to identify or delete a particular diagnostic record.
- Data on your phone: clear the app's data in Android settings or uninstall the app to remove locally stored app data, subject to Android backup behavior.
Sharing You Choose to Do
Some features let you share an image of a trip, export a CSV file containing trip information and GPS points, or copy coordinates from the GPS details screen. When you choose to share, Android's share menu lets you select a destination, such as an email or messaging app. The selected app or service handles the information under its own privacy policy. DevsGround does not receive a copy merely because you share it from your device. Remember that a route or coordinates can reveal where you have been.
Android Backup
Depending on Android backup settings and the app's backup configuration, Android may include saved trips and settings in a device backup stored in your Google account. This is managed by Android and Google under their applicable privacy practices, and DevsGround cannot access your Google account backups. You can review your Android or Google account backup settings to manage available options.
Permissions
- Precise and approximate location: used to measure speed, distance and route from GPS.
- Foreground service (location): allows a trip to continue recording when the screen is off or you switch to another app.
- Notifications: used to show tracking status and optional app messages when enabled.
- Display over other apps: supports the optional floating speed window, if you enable it.
- Vibration: used for speed-limit alerts when configured.
- Internet and network state: used for Firebase services, loading the public More Apps list and Google Play-related features.
- Receive messages and wake lock: may support Firebase Cloud Messaging delivery and related background handling.
- Play install referrer: may be used by Firebase Analytics to understand how the app was installed.
You can review available app permissions and notification controls in Android settings.
Children's Privacy
Speedometer: GPS Speed & Trip is not directed to children under 13, and DevsGround does not knowingly collect personal information from children under 13. If you believe a child has provided personal information through a feature or communication, contact us so we can review the concern.
Safety and Accuracy
Speed, distance and altitude derived from GPS are estimates and may be inaccurate, especially in tunnels, between tall buildings or when the GPS signal is weak. Always follow your vehicle's speedometer and posted speed limits. Do not use the app in a way that distracts you while driving.
Changes to This Privacy Policy
We may update this policy to reflect changes to the app, services or data practices. The updated version will be published on this page with a revised effective date. Significant changes may also be described in app release notes.
