Rainbrow uses the device's TrueDepth camera system to track the movement of your eyebrows. 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. The only depth data collected is related to the movement of your eyebrows: whether they are in an "up", "down", or "neutral" relative position.
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 and prevent accidental jumps.
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.
