Feature Request: Activity Tracker on Local WiFi Only Access

As a user who has other caregivers for my child (grandma, babysitter, etc) it would be beneficial for the app to have the activity tracker on Local WiFi Only access. Currently the caregivers are writing down diapers, feedings and naps not under the monitor then I have to retroactively input them.
Allowing the activity tracker while connected to the local WiFi would allow my caregivers to log these items and view the monitor but still retain privacy when they are not here.
