I do not want to restrict their usage!
I just want a log that has the following (3) things:
(1) What website they went to
(2) What time they got to the website
(3) What time they left.
I dont know if the software can produce this information for you or not. Probably best to wait till Selvan gets back to you with the answer.
Technically what you ask is almost impossible - what happens if they open a web page, and then open another browser and go somewhere else? Now you have two websites open at the same time..
What if she quickly switches between windows so only "sees" the page for a couple of seconds, then navigates elsewhere? That way she could be checking facebook all day, but only record a few minutes of "activity".
Also, apps tend to open sites continuously - for example the facebook app on a phone will check for updates all the time - it does not mean someone is using the app though.
Best to have this conversation with Susie in the "first life", but if you really need a technical solution, I hear this company makes a good product - http://www.qustodio.com/
