It is an application that monitors the status of your camera in the event that it was opened without your permission by an application, which may be a hacking or spying tool.
first activate the protection, then you can exit the app. It will work in background, and at any time it detects a change in your phone camera status about whether it has been used or opened in background, it will notify you with a notification.
with camera protection, stay informed about your camera, and be reassuring.
Be aware that the application doesn't need to connect to your camera to access it; it only checks if the camera is open or not. It runs 24/7 in the background (so there is no need to keep it open; open it for the first time to activate the protection, and after that, you can close it) and will notify you if anything changes about your camera.
