1. Introduction

Welcome to Vibration Meter ("we", "our", "the App"). Your privacy is important to us. This Privacy Policy explains how we handle information when you use our mobile application.

2. Information We Collect

We do not collect any personal information. Specifically:

• We do not collect your name, email address, phone number, or any other personal identifiers.
• We do not collect your location data.
• We do not track your usage or browsing activity.
• We do not use cookies, analytics, or tracking technologies.
• We do not collect device-specific information for advertising purposes.

3. Sensor Data

The App uses your device's built-in accelerometer sensor to measure vibrations. This sensor data is:

• Processed entirely on your device in real time.
• Used solely for displaying vibration readings, waveforms, and statistics within the App.
• Never transmitted to any server, cloud service, or third party.

4. Recorded Sessions

When you use the recording feature, vibration session data (peak values, average values, waveform data) is saved locally on your device using the App's internal storage. This data:

• Remains entirely on your device.
• Can be exported as CSV files by you, at your discretion.
• Is never uploaded or shared automatically by the App.

5. User Preferences

The App stores your settings (theme, language, sensor sensitivity, alert threshold, etc.) locally on your device using SharedPreferences. These preferences are not transmitted anywhere.

6. Third-Party Services

Vibration Meter does not integrate any third-party analytics, advertising, or tracking services. The App does not contain ads.

7. Internet Permissions

The App does not require internet access to function. All features work entirely offline.

8. Children's Privacy

The App does not collect any personal information from anyone, including children under the age of 13. The App is safe for users of all ages.

9. Data Security

Since no personal data is collected or transmitted, there is no risk of data breach from our end. All recorded vibration data is stored securely in your device's internal storage, accessible only by the App.
