This Privacy Policy explains how **Whiteboard – Write & Teach** ("we", "our", or "the app") handles your information. We are committed to protecting your privacy and ensuring you have a safe, transparent, and distraction-free experience.
### 1. Offline-First Architecture
Whiteboard – Write & Teach is built with an **offline-first philosophy**:
- **Canvas Drawings & Notes:** All whiteboards, drawings, handwriting, sketches, and notes are processed and stored exclusively on your device.
- **Documents & Files:** Imported PDFs, images, and exported files (.png, .jpg, .pdf, .wb) are stored locally in your device's private storage.
- **No Cloud Uploads:** We do not operate external cloud servers that store, view, or sync your whiteboard creations.
### 2. Permissions & On-Device Processing
The app requests certain device permissions only when you explicitly trigger related features:
- **Camera (`android.permission.CAMERA`):**
Used solely when you tap to take a photo to insert onto your canvas or scan a document with the OCR scanner.
- **Microphone (`android.permission.RECORD_AUDIO`):**
Used solely to record voice narration when you explicitly choose to record a video lesson. Audio is encoded locally into the MP4 video file saved to your device.
- **On-Device OCR (Google ML Kit):**
Text recognition is performed **100% on-device** using Google ML Kit. Your scanned images and handwritten notes are never transmitted over the internet.
- **Screen Recording / Media Projection:**
Used only when you start a whiteboard lesson recording. No background recording takes place without your active consent and visible status bar notification.
### 3. Third-Party Services & Advertising
To support ongoing app development, the app integrates trusted third-party SDKs:
#### A. Google AdMob (Google Mobile Ads)
We display banner and native ads in non-intrusive dashboard areas. Google AdMob may automatically collect and process certain data, such as:
- Device identifiers (e.g., Google Advertising ID / GAID)
- Coarse location (IP address for general geographic ad localization)
- App interaction, diagnostics, and fraud prevention signals
You can learn how Google uses data by visiting:
[Google Privacy & Terms](https://policies.google.com/technologies/ads)
#### B. Google Play In-App Updates
The app uses the official Google Play Core In-App Updates API to notify you when a new version of the app is available on the Play Store. This operates under Google's standard Play Store services.
### 4. Children’s Privacy
Whiteboard – Write & Teach is designed for general audiences, teachers, and students. We do not knowingly collect personally identifiable information from children under the age of 13. All educational drawings, math formulas, and lesson notes remain on the local device.
### 5. Data Retention & Deletion
Because all whiteboard files and lesson recordings are saved locally on your device:
- You have complete control to delete any board at any time from within the app.
- Clearing the app’s data or uninstalling the app permanently removes all locally stored whiteboards and caches.
### 6. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
