Privacy Policy

1. Information Collection and Processing

Our App is designed to function primarily as a local utility tool to help you monitor, measure, and optimize your device's battery health and charging performance. Accordingly, our data handling practices are as follows:

• Battery Status and Health Data: The App accesses standard battery diagnostics provided by your device (such as charging current, voltage, temperature, capacity, level, and technology). This data is processed in real-time and stored entirely locally on your device's secure SQLite database. We do not transmit this data to any external servers.
• No Personal Information: We do not collect, request, or store any personally identifiable information (PII) such as your name, email address, physical address, phone number, or contacts.

2. Device Permissions Used

To provide its core functionality, the App requires certain system permissions. Each permission is used solely for the reasons detailed below:

• INTERNET: Required to load advertisements from Google AdMob and to fetch general configuration properties.
• POST_NOTIFICATIONS: Required to trigger audio and visual alerts when your battery reaches custom charging or temperature thresholds.
• FOREGROUND_SERVICE & FOREGROUND_SERVICE_DATA_SYNC: Required to run a background service that monitors battery events while charging, ensuring alarms fire accurately even when the App is not actively in focus.

3. Third-Party Services and Advertising

To support development and keep the App free, we use third-party services that may collect information used to identify your device. We integrate with:

• Google AdMob: AdMob uses cookies and unique device identifiers (such as the Google Advertising ID or GAID) to serve personalized advertisements, perform ad diagnostics, and limit the frequency of ads.
• Google Play Services: Used to run core system libraries and facilitate App delivery.

Please refer to the privacy policies of these third-party providers for more details:

4. Cookies

Cookies are files with a small amount of data that are commonly used as anonymous unique identifiers. While our App itself does not set cookies, Google AdMob and Google Play Services may use cookies or mobile identifiers for ad tracking and personalization purposes.

5. Children's Privacy

Our App does not address anyone under the age of 13. We do not knowingly collect personal identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our records. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we can take necessary actions.

6. Security

We value your trust in providing us your device data, thus we are striving to use commercially acceptable means of protecting it. Since all battery test histories and charge session statistics are stored exclusively in your device's local database, they are protected by Android's built-in sandbox security model.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately after they are posted on this page.
