LockDown Browser is a client application that is installed on a local computer. Both the Windows edition and the Mac edition of the browser are based on Chromium, Google’s open-source framework. Students do NOT need Google’s Chrome browser installed; nor will this version affect a Chrome browser that’s already installed.
