Er, I don't understand. You install bitwarden on your phone, you use it, never use a server. Not even required to have internet. The app isn't some crippled client, it can create a vault, encrypt the vault, edit the vault, etc. No cloud or server is required, only if it's useful for you to sync with other devices. Seems weird to call it a dark pattern because they optionally provide a way to sync through a server to keep N clients in sync that's easier to use than trying to rsync between N clients. Having used rsync to keep a work computer, home computer, laptop, and 2 phones synced with a password DB (Keepass) for years, I greatly prefer the sync through server solution, but that's not forced on you.
