Privacy Policy

Your privacy is important to us

Introduction

This Privacy Policy explains how Battery Health Checker ("we", "our", or "us") collects, uses, and protects information when you use our website (batterychecker.org) and our desktop application.

We are committed to protecting your privacy and being transparent about our practices.

Desktop Application

No Data Collection

Our Battery Health Checker desktop application is designed with privacy as a core principle:

  • No personal data collection: The application does not collect, store, or transmit any personal information
  • No usage analytics: We do not track how you use the application
  • No internet connection required: The application works entirely offline
  • Local processing only: All battery information is read directly from your system's hardware and processed locally on your computer
  • No data transmission: No information leaves your device when using the application

What the Application Accesses

The Battery Health Checker application only accesses:

  • Windows Management Instrumentation (WMI) battery information
  • System battery status APIs provided by Windows

This information is displayed to you and is never stored or transmitted anywhere.
