nirih - I installed a special keylogger program on my children's computer and phone. This program is specifically designed for parents.
I can make sure my children are not going to illicit sites, downloading music illegally, or chatting with dangerous people. I can read chat conversations, check the screenshot history, and look at a list of visited web sites from my children's computer activity. This Keylogger provides a full-range of versatile surveillance features for the home.
And also this this sms tracking app https://www.refog.com/sms-spy.html i know all about the messages my child is receiving
