# Privacy Policy for SoundDecibel Pro: Acoustic Meter
This Privacy Policy explains how SoundDecibel Pro handles user information.
### 1. Overview
SoundDecibel Pro is developed as an offline-first acoustic measurement utility. We maintain a strict commitment to user privacy and data security. The application does not collect, record, track, transmit, sell, or share any personal user data.
### 2. Audio Processing & Data Storage
- No Audio Recording: The App measures acoustic sound pressure levels exclusively in temporary local memory on your device hardware to calculate decibel values. No microphone audio streams or ambient sounds are ever recorded, saved to storage, or transmitted across the internet.
- Personal Data: The App does not collect or request any personal identification details (such as names, phone numbers, location data, or contact lists).
- Local Preferences: Any calibration offsets or statistical resets are stored strictly locally on your device and are permanently removed if the application is uninstalled or storage data is cleared.
### 3. Device Permissions Used
SoundDecibel Pro uses strictly minimal device permissions:
- Vibration Permission (VIBRATE): Used solely for subtle tactile haptic feedback during high decibel threshold warnings and UI button taps.
- Network Access (INTERNET): Used exclusively for the internal visual interface rendering container. No personal audio metrics, browsing history, or diagnostic logs are captured or transmitted over any network.
### 4. Third-Party Services & Tracking
The application contains no third-party advertising SDKs, tracking pixels, or cross-platform analytics frameworks. Your noise measurement activity remains entirely private.
### 5. Children's Privacy
Because SoundDecibel Pro collects zero personal data, it complies with standard child protection requirements and is safe for users of all age groups.
### 6. Data Security
All calculations execute locally within the secure sandboxed environment provided by the Android operating system without any external cloud database dependencies.
### 7. Policy Updates
Any future updates to this policy will be published directly within this page.
