Privacy Policy — Sound Level Monitor

Last updated: 2026-10-28

This Privacy Policy describes how Sound Level Monitor ("we", "us") handles your information when you use our application.

1. Microphone Access & Audio Processing

We do not record, store, save, or transmit your voice or any audio.

Sound Level Monitor requires access to your device's microphone solely to measure the ambient sound level (decibels) in your environment. The audio data captured by the microphone is processed in real-time to calculate amplitude.

Any temporary audio data generated during measurement is saved to your device's local cache and is immediately and permanently deleted as soon as the measurement stops. We have no access to this data, and it never leaves your device.

2. Information We Do Not Collect

We do not collect your name, email address, phone number, location, contacts, or any personal files. We do not collect your audio recordings. Our app does not require account registration.

3. Measurement History

Any decibel measurement history or logs you save within the app are stored locally on your device only. We do not upload or have access to this data. You can clear this history at any time from the app's settings.

4. Advertising

We use Google AdMob to display advertisements. AdMob may collect device identifiers (such as the advertising ID), IP address, and usage data to serve personalized or non-personalized ads. You can learn more at https://policies.google.com/technologies/ads.
