Privacy Policy
Effective date: August 22, 2026
1. Introduction
Welcome to GPS Speedometer: Odometer ("we", "our", or "us").
This Privacy Policy applies to the GPS Speedometer: Odometer mobile application, available on the Apple App Store.
GPS Speedometer: Odometer is published by Hoang Tue.
We respect your privacy and are committed to protecting it. This Privacy Policy describes how we handle information in our GPS Speedometer: Odometer mobile application, including your device's location and the limited data collected automatically through third-party services we use to keep the app stable, understand how it is used, and display ads.
By using the app, you agree to this Privacy Policy.
2. Information We Collect
GPS Speedometer: Odometer's core functionality — measuring your speed and the distance you've traveled — relies on your device's GPS. We do not require an account, and we do not collect your name, email address, phone number, or any other information that directly identifies you.
Location data. The app uses your device's location (including, if you grant permission, location in the background) to calculate your current speed, heading, and distance traveled. This location data is processed on your device to power the speedometer and odometer display and is not collected, stored, or transmitted by us to our own servers. Because the app may use your location even when it isn't open (for example, to keep tracking a journey), this can decrease device battery life.
The app uses Firebase Analytics and Firebase Crashlytics, both provided by Google, to help us understand app usage and diagnose crashes. Through these services, the following categories of information may be collected automatically:
- Usage and app interaction data (e.g. screens viewed, features used, session length, app opens) via Firebase Analytics.
- Device and app information such as device model, operating system version, app version, language, and general (non-precise) region, derived from your IP address.
- Crash and diagnostic data via Firebase Crashlytics, including crash logs, stack traces, and the app state leading up to a crash, to help us identify and fix bugs.
- Identifiers such as a Firebase installation ID, used to group events and crash reports without directly identifying you by name.
The app displays ads served by Google AdMob. Through AdMob, the following information may be collected:
- Advertising identifier (e.g. Apple IDFA), used to track you across apps and websites, serve and measure ads, and, where personalized ads are enabled, to help make ads more relevant to you.
- Device and technical information such as device model, OS version, app version, IP address (used for approximate location and fraud/invalid-traffic detection), and general ad interaction data (impressions, clicks).
Depending on your region, AdMob may show either personalized or non-personalized ads, and consent/opt-out choices may be presented to you in-app (for example, via a consent management platform or Apple's App Tracking Transparency prompt) as required by applicable law (such as GDPR in the EU/UK or similar frameworks elsewhere).
We do not use cookies or tracking pixels ourselves, beyond what AdMob uses to serve and measure ads as described above.
3. Third-Party Services
We use the following third-party services to operate the app:
- Firebase Analytics (Google) — helps us understand how the app is used so we can improve it. See Firebase's privacy and security documentation and Google's Privacy Policy.
- Firebase Crashlytics (Google) — helps us detect, diagnose, and fix crashes and errors. See the same Firebase and Google privacy documentation linked above.
- Google AdMob — displays ads within the app and processes advertising identifiers and related data for ad delivery, tracking, and measurement. See AdMob's data disclosure and Google's Privacy Policy.
These services may process data on servers located outside your country of residence. We do not otherwise use third-party APIs, authentication providers, custom databases, or advertising SDKs beyond those listed above, and your precise location and speed/distance readings are never sent to our own servers.
If you download the app through the Apple App Store, Apple may also process information under its own privacy policy. We do not receive your payment details or store account information from the App Store.
4. Your Choices
You control location access through your device's Settings app, where you can grant, restrict (e.g. "While Using the App" only), or revoke location permission for GPS Speedometer: Odometer at any time. Revoking location access will prevent the app's core speed and distance features from working.
Depending on your device and region, you may also be able to limit analytics, advertising, and crash data collection through your device's privacy settings or through in-app consent prompts where applicable.
On iOS, this includes responding to the App Tracking Transparency prompt, which lets you allow or deny tracking for advertising purposes. You can also review Google's ad settings at adssettings.google.com.
Uninstalling the app will stop any further collection of location, usage, advertising, or crash data associated with your device through Firebase or AdMob.
5. Data Retention and Deletion
We do not collect or store your location, speed, or distance data on our own servers — that information is processed on your device and can be removed by clearing the app's local data or uninstalling the app.
Analytics and crash data collected via Firebase is retained by Google according to Firebase's default retention settings, and is used only in aggregate or diagnostic form to improve app stability and user experience.
6. Children's Privacy
We do not knowingly collect personal information from children under 13. The analytics and crash reporting described above collect only technical and usage data, not identifying personal information.
Because the app uses location tracking and displays ads through Google AdMob, it is not intended for use by children under 13, and we do not knowingly direct the app or its advertising to children. If the app is ever configured as child-directed, ad serving is adjusted accordingly (e.g. non-personalized ads only, no tracking) in line with applicable requirements such as COPPA.
7. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Effective date".
