This Privacy Policy explains how Battery Health & Analyzer ("we", "us", or "our") collects, uses, shares, and protects information when you use our Android mobile application (the "App").
By downloading, installing, or using the App, you agree to the practices described in this Privacy Policy. If you do not agree, please do not use the App.
1. Who We Are
Battery Health & Analyzer is a battery monitoring application that shows charging status, temperature, and related device readings, and can alert you when the battery is full, low, unplugged, or hot. We are the developer and operator of the App.
The App does not require you to create an account. Most of your battery readings, alarm settings, and charging history are stored locally on your device. We use third-party services (such as Google AdMob and Firebase) for advertising, analytics, crash reporting, remote configuration, and optional push notifications. You can stop monitoring at any time from Settings.
2. Information We Collect
We collect information in the following categories:
2.1 Information stored locally on your device
The App stores certain information on your device using local storage (SharedPreferences and on-device files). This data is used to provide core App functionality and is not uploaded to our own servers. Locally stored information may include:
- Onboarding completion status
- Theme, language, and temperature unit preferences
- Monitoring, notification, vibration, and start-on-boot preferences
- Alarm settings, including enabled state, thresholds, sounds, volume, and auto-stop options
- Charging history, including battery level samples and charging session times
- Floating widget and power-saver preferences
- Other in-app preferences needed to operate the App
2.2 Information collected automatically
When you use the App, certain information may be collected automatically by us and by third-party services integrated into the App, including:
- Device information (such as device model, operating system version, and app version)
- App usage events (such as screens viewed, alarms toggled, thresholds set, charging state events, ad interactions, and share actions)
- Crash reports, error logs, and diagnostic data
- Advertising identifiers and ad interaction data
- Firebase Cloud Messaging (FCM) device tokens for push notifications
- General technical data required to deliver ads, analytics, remote configuration, and notifications
2.3 Information you provide voluntarily
If you choose to contact us or leave feedback, you may voluntarily provide information such as:
- Your email message content
- Star ratings you submit in the in-app rating flow
- Device and environment details automatically included in feedback emails, such as app version, operating system version, screen resolution, locale, and time zone
We only receive this information if you choose to send it to us (for example, by opening your email app through the feedback feature).
2.4 Information we do not collect
The App does not require account registration and we do not intentionally collect:
- Your name, postal address, or phone number (unless you include them in a support email)
- Precise location or GPS data
- Contacts, photos, camera recordings, or microphone audio
- Payment or financial information (the App is free to use; ads are shown via third-party networks)
- Biometric identifiers
3. How We Use Your Information
We use collected information to:
- Provide and maintain App features, including battery monitoring, alarms, charging history, and optional power-saver tools
- Save your preferences and history on your device
- Display advertisements through Google AdMob and related ad measurement partners
- Measure App performance, usage trends, and feature engagement through Firebase Analytics
- Detect, diagnose, and fix crashes and technical issues through Firebase Crashlytics
- Deliver optional push notifications through Firebase Cloud Messaging
- Update ad units and related flags through Firebase Remote Config
- Respond to feedback, support requests, and user inquiries
- Improve the App, user experience, and content quality
- Comply with applicable legal obligations
4. Local Storage and On-Device Data
Most battery readings, alarm settings, and charging history remain on your device. Uninstalling the App or clearing the App's storage from Android settings will remove locally stored App data from your device, subject to your device's operating system behavior.
Alarm and notification settings are stored locally. The App requests notification permission so your device can show battery alerts. Monitoring may continue in the background while enabled.
5. Third-Party Services
The App uses third-party services that may collect information according to their own privacy policies. These services include:
Google / Firebase
- Firebase Analytics — usage and event analytics
- Firebase Crashlytics — crash and error reporting
- Firebase Cloud Messaging — push notifications
- Firebase Remote Config — feature flags and ad unit configuration
- Google AdMob — advertising
- Google Fonts — typography used in the App interface
- Google Play — App distribution and in-app rating flows

- AdMob & user data
- Firebase Privacy and Security
We do not control how these third parties process data. We encourage you to review their privacy policies.
6. Advertising
The App displays ads provided by Google AdMob. AdMob and its partners may use advertising identifiers, cookies or similar technologies, device information, and interaction data to serve, measure, and personalize ads where permitted by law.
Ad formats used in the App may include:
- Banner ads
- Native ads
- Interstitial ads
- App-open ads
You may be able to limit ad personalization through your Android device settings: Settings → Google → Ads → Opt out of Ads Personalization (wording may vary by device and Android version).
Even if you opt out of personalized ads, you may still see non-personalized advertisements.
7. Analytics and Crash Reporting
We use Firebase Analytics to understand App usage, such as which screens are viewed, when alarms are toggled, when charging starts or stops, when ads are shown, and when users share the App. This helps us improve features and content.
We use Firebase Crashlytics to collect crash logs, stack traces, and limited diagnostic context (such as last alarm type or battery percentage) to identify and fix technical problems. Crash reporting is enabled in release builds to protect development workflows.
Analytics and crash data are generally collected in aggregated or pseudonymous form and is not used by us to identify you personally.
8. Push Notifications
With your permission, the App may send push notifications through Firebase Cloud Messaging. This requires a device messaging token and notification permission on your device.
You can disable notifications at any time through your device settings. If you open a notification, we may log that the notification was opened for analytics purposes.
9. Permissions
The Android App may request or use the following device permissions:
| Permission | Purpose |
|---|---|
| Internet | Required to load ads, analytics, crash reporting, push messaging, fonts, and external links |
| Advertising ID (AD_ID) | Used by ad and measurement partners to deliver and measure advertisements |
| Network state | Used to determine connectivity for ads and related services |
| Notifications (POST_NOTIFICATIONS) | Used to show battery alarms, monitoring status, and optional push messages |
| Foreground service | Used to continue battery monitoring while the screen is locked or the App is in the background |

Ads in the App are configured with a maximum content rating of PG and without child-directed treatment specified, but parents and guardians should supervise minors' use of the App.
14. International Data Transfers
Information processed by third-party providers such as Google may be transferred to and processed in countries other than your own, including the United States. These providers may use appropriate safeguards as required by applicable law.
15. Security
We use reasonable administrative, technical, and organizational measures designed to protect information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

18. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. If changes are material, we may provide additional notice within the App or through other reasonable means. Your continued use of the App after an update means you accept the revised policy.
