Syncing w/ Google Drive

when syncing G: Drive yesterday I noticed that a One Password file named OnePasswordCoreLocalization was blocked from Syncing to the G: Drive.  I for one do not want any of my 1Password files synced with any cloud service, ie G: Drive, Dropbox or even iCloud.

My question is, does 1Password block all syncing activities from outside storage entities so that I do not have to do anything extraordinary to protect my passwords and credit card information?
