Where do I put log out?
The most common placement pattern for a “Log out” button or link is within the upper right-hand corner of a screen. That is the place that has become the intuitive exit area for users, ever since Windows made that top-right 'x' the standard close pattern.
Why is logout button important?
A logout button in mobile surveys usually carries out two functions: saving the data that have been entered and closing the survey to prevent unauthorized entry; it is, therefore, an integral part of any online survey instrument.
