FoneMonitor IS DESIGNED FOR LEGAL USE ONLY. It's a safe Android and iOS device monitoring software that can be used only for the exact purpose of parental control of their kids, by employers to monitor the devices that belong to them as well as on which the employees work, or by you when you have a consent of the device owner.
That could result in severe monetary and criminal penalties imposed on the violator if you failure to do so and it is likely to result in violation of applicable law. That would be better to consult your own legal advisor with respect to legality of using the application in the manner you intend to use it prior to registering, downloading, installing, and using it. FoneMonitor would not be held responsible if a user chooses to monitor a device the user does not have the right to monitor; nor can FoneMonitor provide legal advice regarding the use of the software.
