1. A computer implemented method for managing user applications, the computer implemented method comprising: generating, by a computer, a visual model of user interface display screens of a user application by mapping components displayed within the user interface display screens to screen position coordinates and by mapping the screen position coordinates corresponding to the components to original source code of the user application without accessing the original source code of the user application; generating, by the computer, a runtime policy for each component in a selected set of components within the user interface display screens of the user application based on user interaction with the generated visual model of the user interface display screens; sending, by the computer, the generated runtime policy for each component in the selected set of components within the user interface display screens of the user application to a client device via a network; and tracking, by the computer, activity of each component in the selected set of components within the user interface display screens of the user application running on the client device using data that is tracked and logged on the client device based on the generated runtime policy for each component in the selected set of components.
