Privacy Policy

Last updated: October 10, 2026

Young J Corp. ("Company," "we," "us," or "our") makes the RunHUD and OnTrack mobile applications and the OGQuick web API. This page summarizes how our products handle personal information.

Each product has its own privacy policy, and that policy is the one that applies to the product. If this summary and a product's policy differ, the product's policy prevails.

1. Product Privacy Policies

• RunHUD: runhud.planhub.kr/privacy-policy.html
• OnTrack: ontrack.planhub.kr/privacy.html
• OGQuick: ogquick.com/en/legal/privacy

2. RunHUD

• Running data stays on your device. Heart rate, pace, cadence, distance, and session time are processed on your device and are not sent to our servers.
• Premium purchases. To buy and restore premium features, you sign in with Google or Apple. We store your Google or Apple user identifier, your premium status, and the purchase record (transaction date and receipt) to verify the purchase. Payments are processed by Google Play or the Apple App Store.
• Sensor compatibility information (from November 10, 2026). When you connect a Bluetooth sensor or watch, RunHUD will send technical information about that connected sensor: the name it broadcasts, the Bluetooth services it advertises, your phone platform and OS version, the connection date and time, and a random installation ID generated by the app. This information is not linked to your account, name, or email, and is used only to improve device compatibility.
• What RunHUD does not collect: your name, email address, phone number, location, the Bluetooth (MAC) addresses of your sensors, or information about nearby Bluetooth devices you did not connect.
• Premium and purchase information is stored in Google Firebase. Retention periods are listed in the RunHUD privacy policy.

3. OnTrack

• Workout presets, workout history, app settings, and premium status are stored only on your device and are not sent to our servers.
• OnTrack does not collect your location or personal information such as your name or email address, does not use analytics or tracking services, and does not share data with third parties.
• Premium purchases are processed by the Apple App Store and Google Play. We do not have access to your payment information.
• If you uninstall OnTrack or clear its app data, your presets, history, and settings are permanently deleted. Because we do not store this data on servers, we cannot recover it.

4. OGQuick

OGQuick is a web service with its own account, billing, and data practices. Please see the OGQuick privacy policy.

5. Fitness Platforms

RunHUD and OnTrack do not connect to Garmin Connect or any other fitness-platform account, and we do not receive data from those services. RunHUD reads the live Bluetooth signals that sensors and watches (including Garmin devices) broadcast; as described above, that running data stays on your device.

6. Sharing

We do not sell personal information. For RunHUD and OnTrack, we provide personal information to third parties only with your prior consent or when required by law or legal process.

7. Your Rights

• RunHUD: You can delete your account with "Delete Account" in the app settings, or ask us to access, correct, delete, or stop processing your information.
• OnTrack: All data is on your device. You can view and delete it in the app, or uninstall the app to remove it.

Age requirements differ by product and are described in each product's privacy policy.

9. Changes to This Page

When our products' privacy practices change, we update this page and its "Last updated" date. Notice periods for changes to a product's policy are described in that product's policy.
