As you get done with installing the app and activating it on your child’s phone, you can edit the profile and adjust settings for that profile. You can tap on the Settings button right under that contact and there you can toggle features on and off. If you don’t want to monitor call logs for your son Harry, toggle the Call Logs to off.
Remember, you’d have to set the profiles for all your children added to your Family Dashboard. Otherwise it will be set as Default profile settings.
