SurgicalPerformance prides itself on providing its users with confidentiality and anonymity by offering you features such as enhanced security, further protecting your most sensitive data. One of the safety features of SurgicalPerformance is automatically logging you out after a period of inactivity. This is to protect your data from any prying eyes, and prevents the entry of data by someone else (if on a shared computer for example). You can simply sign back in to pick back up from where you left off.
It is extremely important to try and remember to log out if you are walking away from the computer, especially if it is a public space or on a shared computer. It is not safe to assume that simply closing the window will log you out. In the event that you do not log out, another user may come along and enter data into the wrong account without even realising.
