I would say this is more like a local git repository than what you said. When you add passwords to a vault, then it gets saved to your local copy and then synced to the server. When changes are made elsewhere, it downloads the changes and syncs your local repository.

Now "travel mode" simply removes the local git repository. The data still exists in the cloud, but you have to actively go out and log in to their service to retrieve it. Are you "hiding something" because you deleted a local copy of something from your device? There isn't something on your device that is somehow hidden. It's not there.
