Privacy Policy - Ugong

1) Who we are

Ugong is provided by Saifullah Ahad ("we", "us", "our"). Our website/portfolio is: https://saifullah.ai.

2) What this policy covers

Ugong is a vehicle noise analysis instrument that records engine sound using the device microphone, analyses the acoustic signal on-device, and presents measurement results. This policy explains what the app handles and what it does not.

3) Information we collect

Ugong does not collect, store, transmit, sell, or share personal data. The app has no account system, no user profile, no analytics SDK, no advertising SDK, no crash-reporting SDK, and no third-party tracking.

Ugong requests the Android RECORD_AUDIO permission. The microphone is used only during the guided recording protocol to capture engine noise. Audio recordings are saved locally on the device for analysis and are never transmitted or uploaded.

Vehicle information you enter (make, model, year, cylinder count) is stored only in the app's local database on your device and is never transmitted.

Ugong does not request the INTERNET permission, so the app cannot transmit data from the device.

4) Local data storage

The app stores the following data locally on your device:

• Vehicle profiles: make, model, year, and cylinder count you enter.
• Audio recordings: WAV files of engine noise captured during protocols.
• Analysis results: order spectra and comparison results computed from recordings.

All data is stored in the app's local storage and is removed when you uninstall the app or clear the app's storage from Android Settings.

5) How we use information

Because Ugong does not collect data, there is no server-side use of information. Microphone input and analysis results are used only on-device.

6) Sharing and disclosure

We do not share personal information because we do not collect any.

Ugong does not integrate any analytics, advertising, authentication, cloud, or tracking SDKs.

7) Data retention

We do not retain personal data. Vehicle profiles, recordings, and analysis results remain only in local app storage until you delete them within the app, clear app data, or uninstall Ugong.

8) Your choices and controls

• Microphone permission: you can allow, deny, or revoke microphone access in Android Settings > Apps > Ugong > Permissions.
• Delete recordings: you can delete individual recordings from within the app.
• Delete vehicles: you can remove vehicle profiles and their associated recordings.
• Reset app data: clearing app storage removes all local data.
• Uninstall: uninstalling the app removes Ugong and all its local data.

9) Safety and instrument disclaimer

Ugong is a measurement instrument. It does not name vehicle parts, estimate repair costs, or provide mechanical advice. It reports where acoustic energy sits in the engine's order spectrum. Interpretation of results should be performed by a qualified mechanic.

10) Children's privacy

Ugong is a general utility app and is not directed to children under 13. It does not knowingly collect personal information from anyone, including children.

11) International transfers

Ugong does not transfer any data internationally because it does not transmit data.

12) Changes to this policy

We may update this Privacy Policy from time to time. We will post the updated policy at https://privacy.saifullah.ai/ugong.html and update the effective date above.
