Privacy Policy for Sound Meter: Vibration & Level

Last updated: October 19, 2026

Sound Meter: Vibration & Level is developed and published by Learn Piano Pianika Team.

This Privacy Policy explains how information is collected, used, processed, stored, and protected when you use Sound Meter: Vibration & Level.

We respect your privacy and are committed to providing a transparent and secure user experience.

Information We Collect

Our app does not require users to create an account or provide personal information such as their name, email address, phone number, home address, or date of birth.

The app uses your device's built-in microphone and motion sensors to perform its measurement functions.

Certain third-party services integrated into the app may automatically collect limited information for advertising, consent management, performance monitoring, and related functionality.

This information may include:

  • Device model and manufacturer

  • Operating system version

  • Advertising identifiers

  • IP address

  • Approximate location derived from IP address

  • App interactions and usage information

  • Advertising performance information

  • Crash reports and diagnostic information

The information collected depends on your device, operating system, region, privacy settings, and consent choices.

Microphone Access and Sound Measurement

Sound Meter: Vibration & Level requires microphone access to measure environmental sound levels.

The microphone is used to:

  • Measure surrounding sound levels in decibels (dB)

  • Display real-time sound intensity

  • Calculate minimum, maximum, and average sound levels

  • Display sound level changes over time

  • Provide sound measurement and calibration features

Microphone data is processed locally on your device for sound level measurement.

The app's sound measurement functionality is not intended to record conversations, capture speech content, or transmit microphone audio to external servers.

Sound measurements are intended for general informational purposes and should not be considered a replacement for certified professional sound measurement equipment.

You can revoke microphone permission at any time through your device's Android settings.

If microphone permission is denied, sound measurement features may be unavailable. Other features that do not require microphone access may continue to function.

Motion Sensors and Vibration Measurement

The app uses compatible built-in motion sensors, such as the accelerometer, to detect device movement and vibration.

These sensors may be used to:

  • Measure vibration intensity

  • Display real-time vibration readings

  • Analyze movement along the X, Y, and Z axes

  • Display vibration changes over time

  • Calculate vibration-related measurement values

Motion sensor readings are processed locally on your device.

The app does not require GPS location access to perform vibration measurements.

Measurement accuracy depends on the capabilities, sensitivity, condition, and calibration of your device's sensors.

Surface Level and Edge Level

Sound Meter: Vibration & Level includes digital leveling tools designed to help users check surface alignment and tilt.

These features use compatible device orientation and motion sensors to:

  • Measure surface tilt

  • Check horizontal alignment

  • Check vertical alignment

  • Display leveling indicators

  • Assist with basic positioning and alignment tasks

Level measurements are processed locally on your device.

These features do not require access to your contacts, messages, photos, or personal files.

Results may vary depending on device hardware, sensor calibration, and how the device is positioned.

Measurement Data and Local Storage

The app may store certain information locally on your device to support its functionality.

Depending on the features available in your app version, locally stored information may include:

  • App settings and preferences

  • Calibration settings

  • Measurement history

  • Saved measurement sessions

  • Measurement timestamps

  • Sound measurement results

  • Vibration measurement results

  • Level measurement preferences

Locally stored measurement data is used to provide app features and improve the user experience.

We do not operate a separate user account system or a cloud database for storing individual measurement histories.

Locally stored data may be removed when you clear the app's storage or uninstall the app.

Android backup services may independently back up eligible app data depending on your device settings and operating system configuration.

Internet Access

The app's core measurement features are designed to work without a continuous internet connection.

An internet connection may still be necessary for certain third-party services, including:

  • Loading and displaying advertisements

  • Advertising consent management

  • Google Play services

  • Google Play In-App Review

  • Analytics or diagnostic services, where integrated

  • Other internet-dependent services included in the app

The availability of these services depends on network connectivity, device compatibility, and regional requirements.

Advertising

Sound Meter: Vibration & Level may display advertisements provided by Google AdMob.

Advertisements may include banner advertisements and other supported advertising formats, depending on the app version.

Google AdMob and its partners may automatically collect or process certain information, including:

  • Advertising identifiers

  • Device information

  • IP address

  • Approximate location derived from IP address

  • App interaction information

  • Advertising performance data

This information may be used to:

  • Deliver advertisements

  • Measure advertising performance

  • Prevent advertising fraud

  • Limit advertisement frequency

  • Improve advertising relevance

  • Comply with applicable legal requirements

Depending on your region, device settings, and consent choices, advertisements may be personalized, non-personalized, or otherwise limited.

The app may use Google's User Messaging Platform (UMP) to request and manage advertising consent where required.

Declining personalized advertising does not necessarily prevent all advertisements from appearing. Advertising availability and behavior depend on applicable laws, consent choices, and Google's advertising requirements.

For additional information, please review Google's privacy documentation.

Analytics and App Performance

Where analytics services are integrated, we may use Google Firebase Analytics or similar services to understand general app usage and improve performance.

Analytics information may include:

  • App usage events

  • App version

  • Device model

  • Operating system version

  • Session information

  • General feature interactions

We do not intentionally transmit raw microphone audio or individual sensor measurement histories to analytics services.

Analytics data is used to identify technical issues, improve app stability, and understand general usage patterns.

Crash Reports and Diagnostics

The app may use Google or Firebase diagnostic services to identify crashes, errors, and performance problems.

Diagnostic information may include:

  • Device model

  • Android version

  • App version

  • Crash information

  • Error messages

  • Technical performance information

This information helps us:

  • Identify and resolve bugs

  • Improve application stability

  • Maintain device compatibility

  • Improve overall performance

We do not intentionally include raw microphone recordings or personal conversations in diagnostic reports.

Permissions

The app may request certain Android permissions required for its functionality.

Microphone Permission
