Vroomist Privacy Policy

1. Introduction

Vroomist ("we", "our", or "us") is a vehicle performance measurement app for iOS. This Privacy Policy explains how we collect, use, store, and protect your information when you use the Vroomist app.

Vroomist connects to Bluetooth Low Energy (BLE) GPS devices, or uses your iPhone's built-in GPS, to record and analyze vehicle performance metrics, including sprint times, drag racing distances, and GPS logs. By using Vroomist, you agree to the practices described in this policy.

The app is intended for users aged 13 and older.

2. Information We Collect

Almost everything the app records stays on your iPhone — it is not sent to us. There are two exceptions: the weather lookup described below sends your approximate coordinates to Open-Meteo, and anonymous analytics and crash data go to Firebase. Section 4 summarises where each kind of data lives.

Measurement Data

Location, speed, altitude and motion data from a connected BLE GPS device or your iPhone's own GPS, together with the performance results calculated from it — such as sprint and drag times, trap speeds and G-force — and the environmental conditions recorded alongside them. The app also reads your device's built-in barometer for atmospheric pressure.

Your Own Content and Preferences

Car names you create, optional free-text notes you attach to a measurement, and your app settings such as units and auto-connect. Notes never leave your device; please avoid putting personal information about yourself or others in them.

Device Information

The name, type, connection status and battery level of a connected GPS device.

Weather Data

To provide environmental context for your measurements, the app periodically sends your approximate coordinates to the Open-Meteo weather API and stores the returned conditions locally with your measurements. Nothing else is sent to Open-Meteo. See the "Third-Party Services" section for details.

Diagnostics, Analytics and Performance Data

To find crashes and understand how the app is used, anonymous diagnostic and usage data is sent to Firebase: which features and screens are used, device connections, measurements recorded, exports, settings changes, whether a system permission was granted, your unit preferences and the type of GPS device you use, plus crash reports and performance timings.

This data is pseudonymous — Firebase associates it with a device-generated identifier (Apple's IDFV) — and we do not collect your name, email address or phone number. We do not send the name or address of your GPS device, your vehicle details, or your notes.

3. How We Use Your Information

We use the information we collect to:

• Calculate and display vehicle performance metrics (sprint times, drag times, trap speeds)
• Store your measurement history for review and comparison
• Sync real-time data to the Apple Watch companion app
• Export measurement data as CSV files or images (including saving images to your photo library)
• Improve the app through anonymized analytics, crash reporting, and performance monitoring

4. Data Storage and Security

We take the security of your data seriously. Here is how your information is protected:

• Local storage: All data is stored on your device.
• Encryption: Data at rest is protected by iOS standard file protection encryption. BLE communication is encrypted by Apple's CoreBluetooth framework.
• Limited remote transmission: Only anonymized analytics, crash reports, and performance metrics are transmitted to Firebase servers. An analytics event may include a measurement's elapsed time, but never your saved measurement records, location data, or personal information. The one exception is the Open-Meteo weather query described above, which receives your approximate geographic coordinates in order to return local weather conditions.

5. Third-Party Services

Apple Watch

If you use the Vroomist Apple Watch companion app, real-time speed and measurement data is synced between your iPhone and Apple Watch via Apple's WatchConnectivity framework.

Firebase (Google)

We use Firebase for anonymous usage analytics, crash and error reporting, performance monitoring, and for delivering configuration updates without an app store release. Crash reports include your device model, OS version and app state. No GPS data, saved measurements, notes or personal information is included in anything sent to Firebase. See Google's Firebase Privacy and Security page for details.

Open-Meteo

We use the Open-Meteo weather API to obtain the weather conditions recorded alongside your measurements. Each request sends your approximate coordinates; no account, identifier, measurement data or other personal information is sent. Open-Meteo is operated by Zippenfenig Software & Services (Germany, EU) — see their Terms & Privacy.

App Tracking Transparency Future

If we implement any form of tracking in the future, we will request your explicit consent through Apple's App Tracking Transparency framework before any tracking occurs.

6. Data Sharing

• We do not sell your personal data to anyone.
• We do not share your data with third parties for marketing or advertising purposes.
• We do not display any advertisements in the app.

Data is shared only with the following parties as necessary for the app to function:

• Apple Watch: Real-time performance data synced to the companion app.
• Firebase (Google): Anonymized analytics, crash reports and performance metrics, to improve app quality and stability.
• Open-Meteo: Your approximate coordinates, solely to retrieve local weather conditions.

7. Children's Privacy

Vroomist is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal data, please contact us at vroomistcontact@gmail.com and we will promptly delete such information.

To exercise any of these rights, please contact us at vroomistcontact@gmail.com.

9. Data Retention

• Performance data (sprints, drags, GPS logs) is retained on your device until you choose to delete it.
• Diagnostic logs are stored locally on your device and can be removed by uninstalling the app.

You can delete all app data at any time by uninstalling Vroomist from your device.

10. App Tracking and Advertising

Vroomist currently does not include any advertising or tracking technologies. We do not use the Identifier for Advertisers (IDFA) and we do not participate in any ad networks.

If we implement tracking or advertising-related features in the future, we will update this Privacy Policy and request your explicit consent through Apple's App Tracking Transparency framework before any tracking occurs.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we make changes, we will update the effective date at the top of this page and may notify you through the app or our website.

Your continued use of Vroomist after any changes to this policy constitutes your acceptance of the updated terms.
