**Introduction**  

BatteryManAI, developed by Cheng-Ta Yu, is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and share your data when you use our app on iOS or macOS.

**Data We Collect**  

- **Battery Information**: We collect battery level, cycle count, and charging status to analyze your charging habits and provide AI-driven predictions. This data is processed and stored locally on your device (iOS and macOS).  

- **Device ID (iOS only)**: On iOS, we may collect an Identifier for Advertising (IDFA) to enable personalized ads through Google AdMob, subject to your consent via App Tracking Transparency (ATT). macOS does not collect or use Device ID.  

- **Network Status (iOS only)**: On iOS, we check network connectivity to load ads and ensure app functionality. macOS does not use network connectivity.

**How We Use Data**  

- **Battery Information**: Used to track charging habits over 7-14 days, predict battery health (e.g., when capacity drops below 80% or reaches 1,000 cycles), and provide personalized charging tips (iOS and macOS).  

- **Device ID (iOS only)**: Used by Google AdMob to deliver personalized advertisements, if you allow tracking.  

- **Network Status (iOS only)**: Ensures ads load correctly and supports app functionality. macOS does not use network data.

**Data Sharing**  

- **Google AdMob (iOS only)**: We share Device ID (IDFA) with Google AdMob for advertising purposes, subject to your consent. No other personal data is shared with third parties.  

- **macOS**: No data is shared with third parties, as all data is stored locally and no ads are included.  

- **Local Processing**: Battery information is processed and stored locally on your device and not uploaded to servers (iOS and macOS).

**Your Rights**  

- **Consent**: When you start recording charging data, BatteryManAI displays a privacy alert: "BatteryManAI will record your charging data for AI analysis. Data is stored locally and not uploaded to any server." You can confirm to proceed or cancel to opt out (iOS and macOS).  

- **Data Deletion**: You can delete all recorded charging data via the "Delete All Logs" button, which prompts: "Are you sure you want to delete all charging records? Unanalyzed records cannot be recovered." You can confirm to delete or cancel to retain data. No external data access or deletion requests are needed, as all data is stored locally (iOS and macOS).  

- **Ad Tracking (iOS only)**: You can opt out of personalized ads via iOS settings or the ATT prompt. macOS does not use ads.  

- **App Pricing**: iOS version is free with ads; macOS version is a one-time purchase of $0.99 (or equivalent) with no ads or in-app purchases.
