Hi. If you downgrade your account, you'll be subject to Basic limits - so some notes may not be available to edit because they're too big; but you won't lose any information already submitted. You have the ability to export notes to HTML if you wish, and some other providers will import from an Evernote account. On a Basic account you have a 2 device limit, so you can install Evernote on a mobile and a laptop and sign into an account on either device. When you're signed in on the mobile you can add a password if you wish. If at some stage you decide to upgrade again, it's the same process in reverse.
