InDecibel: Sound Meter
InDecibel: Sound Meter
Effective date: September 19, 2026
This Privacy Policy applies to InDecibel: Sound Meter, package name com.krepelstudio.indecibel, developed by Krepel Studio.
InDecibel is a sound level meter that uses the device microphone to provide an approximate measurement of environmental sound levels in decibels.
InDecibel does not collect, transmit, sell, share, or remotely store personal information.
The application does not require account registration and does not operate a developer-controlled server or cloud database.
InDecibel requires access to the device microphone in order to measure surrounding sound levels.
Microphone input is:
processed locally on the device in real time;
used only to calculate approximate sound levels and related statistics;
not recorded as an audio file;
not stored by the application;
not uploaded to any server;
not transmitted to Krepel Studio;
not shared with third parties.
Audio samples are processed temporarily in device memory only for the purpose of performing the sound measurement.
Permission: android.permission.RECORD_AUDIO
This permission is required to access microphone input and calculate the surrounding sound level.
InDecibel cannot perform its primary sound-measurement function without microphone access.
The application does not use the microphone for voice recording, communication, advertising, user profiling, or analytics.
InDecibel does not require:
location permission;
camera permission;
contacts permission;
storage or media permissions;
notification access;
usage access;
accessibility services;
foreground microphone services;
background microphone access.
The application is designed to measure sound only while the relevant application interface is active.
InDecibel may store application preferences locally on the user's device, such as:
selected application language;
selected visual theme;
onboarding completion state;
sound meter calibration adjustment;
other basic interface preferences required for normal application operation.
These settings are used only for application functionality.
Krepel Studio does not receive or remotely process these locally stored preferences.
Users can remove locally stored application data by clearing the application's data through Android settings or by uninstalling the application.
InDecibel does not create or save microphone recordings.
The application does not require access to user documents, photos, videos, music, downloads, or other personal files for its core functionality.
No sound recording files are created as part of sound-level measurement.
InDecibel does not use AdMob or other advertising networks.
The application does not display advertisements and does not use advertising identifiers for advertising purposes.
No Google User Messaging Platform (UMP) integration is used for advertising consent because the application does not contain advertising.
InDecibel is distributed as a paid application.
The application itself does not use an in-app Google Play Billing system, subscriptions, or in-app purchases.
Payment for downloading the application is handled by Google Play. Krepel Studio does not receive or process the user's payment card information or other payment credentials through the application.
InDecibel does not intentionally include advertising, behavioral analytics, tracking, or user-profiling SDKs.
The application does not send microphone audio or sound measurements to third-party services.
Standard Android operating system APIs required for application functionality are used locally on the device.
InDecibel does not continuously access the microphone in the background.
Sound measurement is intended to operate only while the relevant application interface is active.
The application does not use a background microphone service to monitor the user after leaving the application.
Because microphone audio is processed locally and is not uploaded or stored by Krepel Studio, exposure of microphone content through developer-operated servers is avoided.
Application preferences are stored using standard Android application storage mechanisms and are protected by the Android application sandbox.
Users should keep their device and Android operating system updated to maintain the security protections provided by the platform.
InDecibel does not knowingly collect personal information from children or adults.
The application does not require users to create an account or submit personal information.
Users remain in control of microphone access through Android system permissions.
Users can:
deny microphone permission;
revoke microphone permission at any time through Android settings;
clear locally stored application preferences;
uninstall the application and remove its locally stored data.
Because Krepel Studio does not maintain accounts or a remote database containing user personal information from InDecibel, there is normally no personal user data held by Krepel Studio that requires an access or deletion request.
This Privacy Policy may be updated if the application's functionality, permissions, data practices, or legal requirements change.
Any updated version will be published on the application's Privacy Policy page with an updated effective date.
Users are encouraged to review this Privacy Policy periodically.
