None. Evernote can see what you store there. I do not recommend putting sensitive things there.
Please don't put your credit cards and drivers license in evernote. It's not end-to-end encrypted and not meant to store sensitive items like that. If/when they get compromised, all the items needed to steal your identity will be easily available to those hackers.
If you want something purpose built for that, I'd highly recommend using 1Password. Those items get stored in the same encrypted vault as your passwords and security/privacy is their central focus. As a bonus, they have 1Password for Families, which allows you to set up shared vaults (my wife and I have a shared vault for all credentials, kids SSNs, passport photos, etc, that both of us need) that syncs between multiple people in addition to your personal vault.
