ZFrame is an independent iPhone camera-monitoring app developed by Yifei Li. For privacy questions, contact [email protected].
ZFrame receives Live View images and camera information over USB, including camera/device identifiers, exposure settings, recording status and connection information. It uses this information on your iPhone to display the camera view and controls.
Live View frames are processed in memory, including viewing LUT adjustments where applicable. ZFrame does not upload these images or camera settings to the developer, and does not save the Live View stream as photos or video files on your iPhone. The record button controls recording on the connected camera; resulting files are handled by the camera.
ZFrame does not require an account. The app contains no advertising, advertising identifiers, third-party analytics SDKs or developer-operated cloud service for your camera data. It does not track you across other apps or websites.
The app requests access to communicate with and control the connected camera. You can decline or change the relevant permission in iOS Settings; camera monitoring and control require that access.
ZFrame writes local diagnostic messages to the operating system's logging facilities to help troubleshoot connections and performance. These messages may contain camera identifiers, connection state, timing, errors and purchase product identifiers. The app does not automatically upload these logs to the developer. Apple may separately provide diagnostics under your device or TestFlight sharing settings; those services follow Apple's policies.
Tips are voluntary consumable in-app purchases. They do not unlock features or create a subscription.
Apple processes payments through the App Store. ZFrame receives transaction information from StoreKit to verify and complete a purchase on the device. The developer does not receive your payment card details or Apple Account password. Apple may provide sales and financial reports to the developer and retains its own transaction records under its policies.

Please share only what is needed. Remove sensitive footage, camera serial numbers or other personal information from attachments where it is not relevant. Never send account passwords or payment card details.
