Worklife Barometer is the data controller for all data, and data is stored only on servers administrated by Worklife Barometer. Only a few persons in Worklife Barometer are able to access the technical systems in which the data is stored. The industrial psychologist, to which the individual case has been assigned, has access to the basic information about the person (first name, last name, company, phone number) as well as the response history. Access to these data is only available as long as the case is open. When the case handling ceases, the case “disappears” from the system used by the industrial psychologist.
