It’s just so simple. However, there’s a particular setting within Chrome OS you should pay attention to. That setting is “Sync and Google services.”  Within that setting, you tell Chrome OS what you want to sync in your account – which, in turn, syncs across your devices.  Also: Google Fiber touts 100Gbps broadband in challenge to rival ISPs Out of the box, Chrome OS syncs everything:

Many of these are innocuous and helpful to sync. You probably want all of your bookmarks, settings, and even open tabs synced. The more problematic ones are extensions, passwords, and payment methods. Passwords and payment methods are sensitive information that you might not want to sync across devices. On top of this, you really shouldn’t have Google saving your passwords anyway (use a password manager instead).

Had I allowed extensions to sync, that same extension would have been added to any Chrome OS device I logged in to and wreaked the same kind of havoc. Because of that incident, I prefer to disable the syncing of extensions. Now, how do you manage the sync options in Chrome OS? Let me show you.

Just keep that in mind when you start disabling options for syncing.
