## 2. Data We Collect and How It Is Used
### 2.1 Data You Provide (Stored Locally On Your Device)
The App collects and stores the following information **exclusively on your device** using secure local storage (AsyncStorage). This data is **never transmitted to any external server** by the App itself.
| Data | Purpose |
|---|---|
| **Your name** | Personalised greeting within the App |
| **Last Menstrual Period (LMP) date** | Calculating your Estimated Due Date (EDD) and gestational age |
| **Kick counter session logs** | Tracking fetal movement history |
| **Weight entries & profile** (pre-pregnancy weight, height, BMI category) | Monitoring weight gain against IOM recommendations |
| **Notification preferences** | Enabling or disabling local reminders |
| **Theme preference** (System / Light / Dark) | Remembering your display preference |
**None of this health-related data leaves your device.** We do not operate servers, databases, or cloud storage for this information.
### 2.2 Usage Data Collected by Third Parties
The App integrates **Google AdMob** to display banner advertisements. Google AdMob may collect the following data automatically to serve relevant ads:
- Device identifiers (Advertising ID)
- General location (IP-based, not GPS)
- Device type, OS version, and language
- App usage events (ad impressions, clicks)
This data is collected and processed by Google LLC under their own Privacy Policy. We have configured ads to request **non-personalised ads only**, which limits data collection for advertising purposes.
> For more information, see [Google's Privacy Policy](https://policies.google.com/privacy) and [Google AdMob's data practices](https://support.google.com/admob/answer/6128543).

## 4. Local Notifications
If you enable reminders, the App schedules **local push notifications** entirely on your device. These notifications:
- Are generated and delivered locally — no data is sent to any server
- Include daily kick-count reminders and weekly pregnancy milestone alerts
- Can be disabled at any time from within the App settings or your device's system notification settings
---
## 5. Data Sharing
We do **not** sell, rent, trade, or share your personal health information with any third party.
The only data that may flow to third parties is advertising data collected by **Google AdMob** as described in Section 2.2, which is subject to Google's own privacy policy and not controlled by us.

## 6. Data Storage and Security
All personal information you enter (name, LMP date, weight entries, kick sessions) is stored solely on your device using Android's secure local storage. We do not have access to this data. If you uninstall the App, all locally stored data is permanently deleted.
