Privacy Policy

1. Scope

This policy applies to the Volume Changer application (listed as “Fine Volume Control” or a localized equivalent on the App Store, the “App”) and its support channel. The App is operated by the Volume Changer developer.

2. Data handled on your device

The App stores this information in its local on-device storage to provide its features. The current system volume is also processed on-device only as needed to adjust volume. The developer does not transmit these preferences or selected photos to a developer-operated server or use them for advertising.

3. Photo library access

The App opens your photo library only when you choose to change the background of the Glass or Liquid Glass design. It handles only the image you select. A copy is stored in the App's on-device storage and is not sent to the developer or RevenueCat.

4. Data processed for in-app purchases

The App uses the Apple App Store and RevenueCat to display and process Pro Mode and developer-support purchases, check entitlements, and restore purchases. These services may process:

• An anonymous App User ID generated by RevenueCat
• Transaction and purchase-history information such as product, purchase date, and purchase status
• Purchase receipts issued by Apple
• Technical information such as device type, OS, app version, and last-seen time

This information is used to provide purchases, verify entitlements, restore access, prevent fraud, provide support, and understand purchase activity in aggregate. The App does not provide RevenueCat with your name, email address, or a custom account ID. Apple processes payment details such as card numbers; the developer does not receive them.

For more information, see the RevenueCat Privacy Policy and Apple's App Store & Privacy notice.

5. Data the App does not collect or use

The App does not require account registration and does not access your name, address, location, contacts, health information, microphone, or camera. It includes no advertising or crash analytics SDK and does not track you across other companies' apps or websites.

As explained above, photo-library access is limited to the image you choose for an on-device background.

6. Support and this website

If you use the support form, the developer uses the content you submit and any contact information you voluntarily provide to respond and resolve the issue. The form is provided through Google Forms. Do not submit passwords, payment details, or other sensitive information.

This privacy page contains no advertising, analytics, or tracking scripts. It is delivered through Firebase Hosting, where Google may process access information such as IP addresses for delivery and security.

7. Retention and deletion

• You can replace or clear a selected background photo in the custom-design settings.
• You can delete the App's local preferences and background photos by uninstalling the App.
• Apple or RevenueCat may retain purchase records as needed for restoration, fraud prevention, accounting, and legal obligations.
• Support information is deleted within a reasonable period after it is no longer needed, except where retention is required by law or to resolve a dispute.

To request access to or deletion of information processed through RevenueCat, contact the developer using the support page below. Requests are handled subject to applicable law and each service's retention obligations.

8. Security and international processing

The App uses encrypted connections for purchase-related communications. Service providers such as RevenueCat, Apple, and Google may process information outside your country of residence. Each service manages information under its terms and applicable laws.

9. Changes to this policy

This policy may be updated when the App, its service providers, or applicable requirements change. Material changes will be communicated on this page or in the App.
