Privacy Policy

Effective Date: July 9, 2026

WR Tools ("we," "our," or "us") operates the CPU Bar mobile application (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App and the choices you have associated with that data.

By downloading and using the App, you agree to the collection and use of information in accordance with this policy.

1. Information Collection and Use

Our App is designed to provide real-time system utilities (CPU monitoring) on your Android device.

A. Core Functionality (No Personal Data Collected)

• The App reads hardware performance metrics (such as processor utilization) locally on your device to display the overlay bar.

• This system performance data is processed entirely in real-time within the device's volatile memory. We do not collect, store, or transmit any of your device’s internal hardware or performance statistics to external servers.

B. Device Permissions

To function properly, the App requires specific Android system permissions. You will be asked to grant these permissions when activating features:

• SYSTEM_ALERT_WINDOW (Display over other apps): Required to display the real-time CPU performance bar as a visual overlay on top of other running applications.

• FOREGROUND_SERVICE & FOREGROUND_SERVICE_SPECIAL_USE: Required to keep the local CPU tracking process running reliably in the background when the screen is active.

• POST_NOTIFICATIONS: Required on Android 13 and above to display the ongoing status notification, which allows you to easily reopen the App’s settings.

2. Third-Party Services & Advertising

To keep our App free of charge, we use third-party advertising services provided by Google.

Google AdMob Our App integrates Google AdMob to display banner ads and rewarded video advertisements. AdMob may collect and use pseudonymous data (such as your device's Advertising ID, IP address, coarse/approximate location data, device information, and ad interaction data) to serve personalized or non-personalized advertisements, ensure fraud detection, and measure ad performance.

Google's use of information collected through AdMob is governed by Google’s Privacy Policy:

• Google Privacy & Terms

• How Google uses information from sites or apps that use our services

You can opt out of personalized advertising in your Android device settings under "Google" > "Ads".

3. Data Security

The security of your information is important to us. Since the App does not transmit or store personal user data on external servers, your data remains secure within your local device environment. Please remember that no method of transmission over the internet, or method of electronic storage is 100% secure, but we minimize risk by avoiding data collection entirely.

4. Children's Privacy

Our services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your child has provided third-party services within our App with personal data, please contact the respective third-party service providers or adjust your device's ad preferences.

5. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top. You are advised to review this Privacy Policy periodically for any changes.
