This Privacy Policy explains how Auto Volume Control: Per App ("the App"), developed by Krepel Studio, handles information when you use the App.
Application package: com.krepelstudio.autovolumecontrol
Auto Volume Control: Per App allows users to assign a preferred media volume level to selected Android applications.
When a configured application becomes active, the App detects which application is currently in the foreground and applies the locally saved media volume setting.
The App is designed to perform this functionality locally on the user's device.
Krepel Studio does not operate a server for this App and does not collect or transmit users' app-usage information, volume rules, or other personal data to Krepel Studio.
To provide its core functionality, the App processes limited information locally on the device.
The App accesses information about applications that can be launched on the device, such as:
application name;
application icon;
package identifier.
This information is used only to display applications inside the App and allow the user to assign individual volume settings.
The App does not upload or transmit the list of applications to Krepel Studio or any external server.
When the volume automation feature is enabled, the App uses Android AccessibilityService functionality to determine the package identifier of the application currently in the foreground.
This information is processed locally only to determine whether a saved volume rule should be applied.
The App does not create or store a history of applications you open and does not transmit foreground application information to Krepel Studio.
The following information may be stored locally:
selected applications;
configured volume levels;
enabled or disabled volume rules;
application settings;
theme selection;
language selection;
onboarding state;
purchase entitlement status required for Pro functionality.
These settings are stored in the App's private storage on the device.
Auto Volume Control: Per App uses Android's AccessibilityService API for one specific purpose:
to detect which application is currently active so that the App can automatically apply the volume level previously configured by the user.
The AccessibilityService is not used to:
read messages;
read passwords;
read typed text;
inspect the contents of other applications;
capture the screen;
perform clicks or gestures on the user's behalf;
collect browsing history;
collect personal communications;
monitor user activity for advertising or analytics purposes.
The App does not require access to the accessibility window content for its intended functionality.
Accessibility access must be enabled manually by the user in Android system settings.
Users can disable Accessibility access at any time through Android Accessibility Settings. Disabling the service will stop automatic per-app volume switching.
Auto Volume Control: Per App is not represented as an accessibility tool designed primarily for users with disabilities.
The App uses only permissions and access required for its functionality.
The App uses Android audio-control functionality to change the device's media volume when a configured application becomes active.
This access is required for the core per-app volume feature.
AccessibilityService access is used only to identify the currently active application as described in this Privacy Policy.
The user must explicitly enable this access through Android system settings.
The App queries applications that can be launched by the user so they can be displayed in the application list.
The App does not require unrestricted access to every package installed on the device and does not use the QUERY_ALL_PACKAGES permission for its intended functionality.
The App does not use Notification Access or Usage Access for its core functionality.
It does not require access to the user's contacts, location, microphone, camera, SMS messages, call logs, or personal media files.
The App stores its settings and configured volume rules locally in the application's private storage.
Auto Volume Control: Per App does not read, upload, modify, or process the user's personal documents, photos, videos, audio files, or other files stored on the device.
The App does not provide cloud storage or synchronization.
Local App data can be removed by clearing the App's storage in Android system settings or by uninstalling the App.
Auto Volume Control: Per App does not contain advertising.
The App does not use Google AdMob, Google User Messaging Platform (UMP), or other advertising SDKs.
No information is collected or shared for advertising or advertising profiling by the App.
The App uses Google Play Billing to provide optional Pro functionality through Google Play.
Purchases are processed by Google Play.
Krepel Studio does not directly receive or store your payment card number, banking credentials, or other payment method details.
The App may receive and process billing information provided by Google Play that is necessary to determine purchase status and restore purchased functionality, such as:
purchased product identifier;
purchase status;
purchase token or equivalent purchase information supplied by Google Play.
This information is used only to manage the user's entitlement to purchased functionality.
Payment processing and related information handled by Google are subject to Google's own terms and privacy practices.
The App uses Google Play Billing for in-app purchases.
The current version does not use:
advertising SDKs;
analytics SDKs;
third-party tracking SDKs;
external cloud databases;
developer-operated analytics servers.
Android and Google Play platform services may process information according to Google's own terms and privacy policies.
Krepel Studio does not sell users' personal data.
The App does not transmit configured volume rules, foreground application information, or the user's application list to Krepel Studio or third parties.
Information required to complete or verify Google Play purchases may be processed by Google Play as part of the billing process.
The App is designed to minimize access to data and perform its primary processing locally on the user's device.
Application preferences and volume rules are stored within Android's application-specific storage.
Because the App does not operate a backend server for its core functionality, the locally stored volume configuration and foreground application information are not uploaded to Krepel Studio.
Users should keep their Android device and operating system updated and use appropriate device-level security protections.
Users remain in control of the permissions and settings used by the App.
You can:
enable or disable individual application volume rules;
modify or delete configured volume settings;
disable AccessibilityService access at any time;
clear the App's locally stored data through Android settings;
uninstall the App to remove locally stored App data;
manage Google Play purchases through your Google Play account.
If you have questions regarding privacy or data handling, you may contact Krepel Studio using the email address listed below.
The App does not intentionally collect personal information from children or other users.
The core volume-control functionality operates locally on the device and does not create user accounts or transmit user activity information to Krepel Studio.
This Privacy Policy may be updated if the App's functionality, permissions, data practices, Google Play requirements, or applicable platform requirements change.
When changes are made, the "Last updated" date at the top of this Privacy Policy will be revised.
Users are encouraged to review this Privacy Policy periodically.
