Privacy Policy

Last Updated: December 22, 2025

At CastX, we believe your privacy is a fundamental right. This Privacy Policy describes how we collect, use, and handle your information when you use our mobile application. Our core mission is to provide high-quality screen mirroring while keeping your data private.

1. The "Local Data" Guarantee

The primary function of this app—Screen Mirroring—is processed entirely on your local device and your private Wi-Fi network.

• No Content Collection: We do not record, store, or transmit the content of your screen, your camera, or your microphone to any external servers.
• Direct Streaming: Your screen data is streamed directly from your iPhone to your Chromecast device. We have no access to this stream.

2. Information We Collect

To improve the app and manage your premium features, we collect limited, non-sensitive data through our trusted partners:

• Product Analytics (via Mixpanel): We use Mixpanel to understand how users interact with the app. This data is anonymized and used solely to improve performance. It does not include your screen content.
• Subscription Management (via RevenueCat): We use RevenueCat to handle in-app purchases. This collects purchase history to ensure your premium features work. Financial details are handled securely by Apple.
• Device Info: We collect basic info like device model and OS version to troubleshoot bugs and ensure compatibility.

3. Third-Party Services

We only share data with the following providers to maintain app functionality:

• Mixpanel: For anonymized usage analytics.
• RevenueCat: For processing and validating subscriptions.
• Apple: For processing all financial transactions.

4. Data Security

Since we do not collect personal identities or screen content, there is no risk of your private media being leaked from our servers. Analytical and purchase data are stored securely by our partners following industry-standard encryption protocols.
