Privacy Policy

WheelVolume

Last updated: March 15, 2026

CK Tools ("we", "us", or "our") operates the WheelVolume mobile application (the "App"). This Privacy Policy informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.

🔒 Privacy First: We do NOT collect, store, or transmit any personally identifiable information (PII). WheelVolume works entirely offline and locally on your device.

1. Information Collection and Use

WheelVolume is a simple volume control tool that provides a floating wheel overlay to adjust your device's volume. The app:

Does not collect any personal information
Does not access the internet (except for AdMob/Google Play services)
Does not track your usage or behavior
Does not share any data with third parties (except as described below)

2. Permissions and Their Purpose

WheelVolume requires the following permissions to function:

Display Over Other Apps

Why we need it: To show the floating volume control wheel overlay on top of other apps.

How we use it: The app creates a circular overlay that appears when you trigger it. This overlay allows you to control volume without leaving your current app.

Modify System Settings

Why we need it: To adjust your device's volume levels when you interact with the wheel.

How we use it: When you rotate or tap the wheel, the app uses Android's AudioManager API to change the system volume. No data is recorded or transmitted.

3. Third-Party Services

WheelVolume may include the following third-party services:

Google AdMob (Rewarded Video Ads)

We use AdMob to provide optional rewarded video ads that unlock premium features (themes, size customization, position settings) for 12 hours. AdMob may collect device identifiers and usage data according to Google's Privacy Policy.

Google Play Billing (In-App Purchases)

We use Google Play Billing for lifetime premium purchases. All payment processing is handled by Google Play. We do not have access to your payment information. Transactions follow Google's Privacy Policy.

4. Data Storage and Retention

WheelVolume stores the following data locally on your device only:

App settings (theme, wheel size, position, behavior preferences)
Premium unlock status (whether you purchased or unlocked via ad)

This data is stored using Android's SharedPreferences and is automatically deleted when you uninstall the app.

5. Children's Privacy

WheelVolume does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children.

6. Changes to This Policy

We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes. Changes are effective when posted on this page.
