That's not a notably missing phrase, because it's not open source. Maybe it's notable because you don't trust closed source security products, but if so, you didn't say that. :) Not that I disagree with you. I use 1Password, but in my opinion the fact that it is closed source is definitely a mark against it. If there was anything built on top of, say, GPG that had remotely similar functionality, I would totally use that. Maybe there is and I don't know about it.
You might be interested in STRIP[1] which is built on SQLite and SQLCipher, the latter being an open-source encryption codec for the former. It's up to the user to decide whether and how to use Dropbox, Google Drive, etc., for syncing.
