Chromesync, is a tool provided with every installation of Google Chrome and Chrome OS. It's purpose, is to retreive and store your browser settings, bookmarks and preferences. If you're working with several computers (Office and Home) and wish to have all of your browser data mirrored on both, Chromesync is the way to go.
To enable Chromesync: click on the Chrome menu (three small bars on the top/right corner). Choose Settings. In the tab that opens, there should be a "Sign into Chrome" option. Click on that, and enter your Centennial mail credentials. Click to save this. Once signed in, any bookmarks, themes, and browser services will be stored in an encrypted file on Google's servers. To retreive these settings, just sign into another installation of Chrome, or a Chrome OS Notebook. They'll return automatically.
