1. How does Desklog Work?
Once the users are added to the Desklog company account, they will be able to receive the invitation with credentials to log in to Desklog. The admin or the Desklog owner will be able to track the user.
Desklog will be able to track Applications, URLs, Documents, etc. The Desklog owner or the admin will be able to categorize the tracked application as either Productive or Non-productive or Neutral apps. Depending on what type of application is accessed by the user the productivity graph is displayed. The auto screenshots of the working window of the user will be captured every few minutes.
Refer to question 2 under section 1.2 to know how the users are tracked.
2. What is the difference between Time At Work and Productive Time?
The total amount of time spent by the user on the system is called the Time At Work and this time is the sum of productive time, neutral time, non-productive time.
The time spent on the productive application is called the productive and similarly, on other types of applications, it is called non-productive or neutral time.
