Rules automatically activate and deactivate according to the schedule that you have set up for them. You don't have to do anything else once they are set up.

A rules will stay in the "Inactive" bin until its time to turn on. For example a “Study Time Rule" which is set to block internet traffic from 5.30pm - 8pm.

This rule will move into the "Active" bin at 5.30pm where it will stay until 8pm then turn off and return to the "Inactive" bin.

A "Inactive" rule does not mean that it's disabled. There is a separate button to disable your rules.
