Privacy Policy for TV Cast - Screen Mirroring

Last Updated:  May 11, 2026 (Updated to comply with Android 14+ requirements)

1. Introduction

Sanxview ("we", "our", "us") is committed to protecting your privacy. TV Cast - Screen Mirroring is a premium tool that mirrors your screen to compatible displays over a local network. This policy explains why we require certain permissions and how we ensure your data never leaves your control.

 2. Our "Privacy First" Commitment

We believe your data belongs to you. Unlike many other apps:

- ✅ No Data Collection: We do not collect, store, or transmit any personal information.

- ✅ No Tracking: We do not use analytics, crash reporters, or tracking SDKs.

- ✅ No Cloud Servers: Your screen and audio data are streamed directly to your TV. We do not have access to your sessions.

- ✅ No Account Required: You can use all features without an account or login.

 3. How the App Works (Data Processing)

All data processing happens locally on your device and your private WiFi network.

A. Screen Mirroring

The app uses the Android MediaProjection API to capture your screen. This data is converted into a stream and sent directly to your target display device on the same network. It is never saved or uploaded.

B. Audio Mirroring (Internal Audio)

To provide a complete experience, the app captures System Audio (music, games, app sounds) using the AudioPlaybackCapture API.

- Important Note: While Android requires us to request the "Record Audio" permission for this, the app does NOT record your physical microphone or voice. It only captures internal digital audio from your apps.

C. Drawing & Annotation Tool

The app includes a feature to draw or highlight on your screen during mirroring. This uses the System Alert Window permission to show a transparent drawing layer. None of your drawings are saved.

4. Permissions & Their Purpose

We only request permissions essential for the app's core functionality:

| Permission | Purpose |

| :--- | :--- |

| Media Projection | To capture and stream your screen content to your TV. |

| Record Audio | Required by Android to capture internal system audio (not your voice). |

| Internet & WiFi | To communicate with your TV/Display device on your local network. |

| Nearby WiFi Devices | To discover and connect to streaming devices without requiring your GPS location (Android 13+). |

| System Alert Window | To provide the "Screen Sketch" tool that lets you draw over other apps. |

| Foreground Service | To ensure mirroring stays active when you leave the app to show other content. |

5. Local Storage

The app stores a minimal amount of data only on your device's internal storage:

- User settings (theme, quality preferences).

- Connection history (names/IPs of previously connected TVs) to make future connections faster.

- This data never leaves your phone. You can clear it anytime by clearing the app's cache or uninstalling it.

---

 6. Third-Party Services

The app is built using trusted open-source libraries:

- Lottie: For smooth UI animations (runs entirely offline).

- Glide: For efficient image handling (runs entirely offline).

- NanoHTTPD: A local-only web server used to facilitate the stream between your phone and TV.

- ZXing: For local QR code scanning.

None of these libraries collect or transmit your data.

7. DRM and Content Restrictions

Please note that some high-value streaming services (like Netflix, Disney+, or Amazon Prime) use DRM (Digital Rights Management). These services may block screen mirroring, resulting in a black screen. This is a restriction imposed by the content provider and cannot be bypassed by our app.

8. Children’s Privacy

Since we do not collect any personal information, our app is fully compliant with COPPA and other children’s privacy regulations. We do not knowingly or unknowingly collect data from children under 13.
