This Privacy Policy explains how XuanScope ("App"), developed and operated by Jietao Huang (developer account "JIETAO", "we", "us", "Developer"), handles information when you use the App.
In short: the App works entirely on your device. We do not operate any server that receives your personal data, we do not collect analytics or advertising identifiers, and we do not share any data with third parties for commercial purposes.
The following data is captured, processed, and stored exclusively on your device. It never leaves your device and is not accessible to us:
| Data | Purpose | Where it stays |
|---|---|---|
| Camera preview and USB (UVC) camera video | Multi-camera directing and composition | Device only |
| Microphone audio | Audio mixing, noise suppression, and recording | Device only |
| Images and videos you import | Use as picture sources in your composition | Device only |
| Recordings (MP4) and photos (JPEG) you create | Saved by your own action | Your device's media storage |
| App settings (layouts, overlays, shortcuts, streaming URLs) | Remember your configuration | Device local storage |
| Diagnostic logs (crash info, device model, OS version) | Troubleshooting problems you report | Device local storage; see Section 4 |
You can delete all of this at any time by deleting the files in your gallery or file manager, or by uninstalling the App.
When you use the "phone source" feature to connect another phone on your Wi-Fi network:
This traffic never passes through, and is not accessible to, any server of ours — we do not operate one. Security note: these features rely on general-purpose network protocols without end-to-end encryption or strong peer authentication. Use them only on networks you trust, and see our Terms of Service for details.
If you purchase a subscription, the payment is processed entirely by Google Play. We never see your payment method, your billing address, or your Google account credentials. The App only checks, locally on your device, whether a valid subscription is associated with your Google Play account.
Google's handling of your payment and account data is described in Google's own policies:
If you contact us for support at hjacto@gmail.com (for example, by using the "export diagnostic log" feature and emailing it), we receive the content you choose to send — typically your message and, if you attach it, a diagnostic log containing device model, Android version, app version, and crash details. We use it solely to diagnose and resolve your reported issue, keep it only as long as needed for that purpose, and do not add it to any marketing or profiling system.
All processing happens on your device or between your own devices on your local network, which limits exposure by design. Because we do not collect or store your personal data on any server, there is no developer-held database that could be breached. Local network transmissions are not end-to-end encrypted; please use trusted networks.
The App is a professional directing tool and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us personal information, contact us and we will delete it.
Because we do not maintain any server-side store of your personal data:
We retain support correspondence (Section 4) only as long as necessary to resolve your issue. The App itself retains nothing outside your device.
We may update this Policy to reflect changes in the App or applicable law. The current version is always available in the App, and the "Last updated" date above will change when we do. Material changes will be highlighted in the App.
