There's really not much of a difference between syncing via Dropbox (or similar products) and cloud services with the following characteristics: - Client-side encryption, meaning the service has no way to obtain your cleartext passwords (short of planting a backdoor, which is a vector that applies to all password managers). - Full offline support, with the ability to export your database. This becomes relevant when the service is down, you're running into billing problems, or if the company goes out of business entirely. - Availability of a native client (as opposed to web apps or extensions that act as a thin layer on top of a web app). Planting a backdoor that leaks your secrets is significantly harder when you also need to compromise the vendor's signing key, as opposed to just breaching their web server and adding some JS file.
