Dr.Web Family Security allows you to create schedules of three types: Allow, Block or Limit time.
The Allow type blocks an app or app group for the entire day except for a specified time period.
The Block type blocks an app or app group on a specified time.
The Limit time type limits the time family member can use an app or app group to several hours a day.
You can add the same app in different schedules. If you add an app to schedules of different types that have conflicting time frames, you will have to choose which schedule will remain enabled.
