please, im begging you. i just do it to my brother, no intention to others.
Unless you have your brother's permission (and I seriously doubt that you so, else you'd already have said so) and you have made it known to him specifically what you are recording and for what purpose it is being recorded this is illegal. We generally give users the benefit of the doubt when it comes to things which are legal in some instances and not in others, but there are precious few legitimate reasons for using keyloggers and all of them are covered by written privacy policies.
In short, no, we can't help you with this.
