ChromaVector - Privacy Policy

 

Last updated: June 05, 2026

This Privacy Policy explains how Mel-Spectrum Analyzer ("we," "our") processes your data when you use our mobile application.

 

1. Audio Data Collection and Processing

The ChromaVector application provides real-time chromatic and harmonic analysis tools.

·         Nature of the data: The application accesses your device's microphone to analyze sound frequencies and pitch.

·         Processing: Captured audio data is processed exclusively in real time by our built-in analysis engine (developed in Rust) directly on your device.

·         Storage and transmission: No audio data is recorded, transmitted, or stored on external servers. All processing is strictly local and temporary.

 

2. Advertising and Third-Party Data

To keep the application free of charge, we integrate the Google Mobile Ads SDK (AdMob).

·         Data collected by third parties: The AdMob SDK may automatically collect advertising identifiers from your device (e.g., the Android Advertising ID) in order to measure ad performance and deliver personalized advertisements based on your preferences.

·         Sharing: This data is processed by Google in accordance with their own privacy policies.

·         Control: You can manage your advertising preferences and reset your advertising identifier through your Android device settings, under "Privacy" or "Google > Ads."

 

3. Preference Data

We save your personal settings locally (visualization mode, notation style, measurement smoothing, noise threshold, etc.) in order to improve your user experience. This data is stored exclusively on your device and is neither synchronized nor shared.

 

4. Your Rights

You retain full control over your use of the application:

·         Permissions: You may revoke microphone access permission at any time through your device settings. Please note that doing so will render the application non-functional.

·         Transparency: We are committed to not collecting any personally identifiable information (such as name, address, contacts, or precise location).
