Effective Date: June 15, 2025
Adaptive Sound Level ("we", "our", or "the App") is committed to respecting and protecting your privacy. This Privacy Policy explains how our application collects, uses, and protects information in compliance with Google Play policies and user expectations.
Adaptive Sound Level is a standalone mobile application designed to adapt the device volume based on an estimate of the ambient noise level using brief, local audio recordings. These recordings are processed only on the user’s device and never transmitted, stored, or shared. The app functions completely offline and does not collect any personal or sensitive user data.
Audio Recording
The app uses the device’s microphone to record short audio samples (250 milliseconds every 5 seconds) through a foreground service. These recordings are used only to estimate environmental sound levels (e.g., volume in decibels).
Local Processing Only
All audio data is processed in real time and discarded immediately after analysis. No recordings are stored or saved, even locally.
No Internet Access
The app does not access the internet and does not transmit any data to the developer or to third parties.
No Personal Information
The app does not collect or access any personally identifiable information (PII), behavioral data, or device identifiers for analytics or advertising purposes.
The app requests the following permissions solely to ensure proper functioning:
RECORD_AUDIO
Required to capture ambient audio in short bursts to calculate the ambient sound level.
MODIFY_AUDIO_SETTINGS
Used to change the volume of ringtones, notifications and alarms according to the user settings and estimated ambient noise.
FOREGROUND_SERVICE
Enables the app to run continuously in the background to monitor ambient noise.
FOREGROUND_SERVICE_MICROPHONE
Ensures compliance with newer Android versions when using the microphone in a foreground service.
READ_PHONE_STATE
Used to detect phone call status to avoid recording during calls, preventing audio conflicts and ensuring user privacy.
RECEIVE_BOOT_COMPLETED
Allows the app to restart its service after the device is rebooted (if enabled by the user).
These permissions are used exclusively for functional purposes and not for tracking, profiling, or collecting data.
Adaptive Sound Level does not share any data because no user data is collected or stored. There is no integration with advertising networks, analytics services, or any third-party SDKs.
Adaptive Sound Level does not expose children to any inappropriate content or experiences.
The app:
Contains no visual, audio, or textual content that may be inappropriate for minors.
Does not collect any user data, making it inherently privacy-safe for all age groups.
Can safely be installed on devices with parental controls.
Is free of ads, tracking, or external communications, ensuring no hidden data activity.
While the app is not specifically targeted toward children, its use by children is risk-free under parental guidance.
Because the app does not collect or retain any data, there is no data at risk of being exposed or misused. The app follows Android best practices to minimize permissions and ensure privacy-focused design.
We may occasionally update this Privacy Policy. Any changes will be reflected here with an updated "Effective Date" at the top of the page.

No personal or sensitive user data is collected.
All processing occurs locally, offline, and is temporary.
Permissions are used strictly for delivering the core functionality.
The app is privacy-friendly by design and does not communicate with any server.
