【IMPORTANT】: Before version 1.3.0, FaceJoy need to use TrueDepth System for playing,so it only compatible with iPhone X series which has notch. After version 1.3.0, FaceJoy add Dual-Screen Mode for playing, so ALL iOS Devices can play with it. 【Dual-Screen Model】: Cast the iPhone to the second screen by AirPlay, the iPhone can be transformed into a body motion controller, and you can interact with the large screen by waving the iPhone (similar to Switch JoyCon). Note: This function requires a smooth network environment, otherwise delay may occur. FaceJoy uses the device's TrueDepth camera system to track the movement of your face(such as blink,smile,open mouth and so on) to controller the game elements . This allows for a unique user experience — a game you can play with your face. In order for this functionality to be possible, the app requires access to your device's camera. This access can be toggled on or off at any time in your device's settings. The camera images and resulting depth data are only used for gameplay purposes. The live video feed is never used, and its data is never stored locally or remotely. Camera access is required to get depth data from Apple's API's. This data is stored on the device only for the duration of your current game session. Every time the home screen is presented or the app is closed, the data is deleted. This data is used to make your gameplay experience more enjoyable. Face data is never stored remotely, given to third parties, or used for any non-gameplay purposes. The face data only remains on your device, and never leaves your device at any time. If you have any questions, please reach out to me at kittenyang@icloud.com Thanks for playing FaceJoy!
