Using this for the evernote-account-plugin.apparmor:
{
    "template": "ubuntu-account-plugin",
    "policy_groups": [
        "accounts",
        "audio",
        "networking",
        "webview"
    ],
    "policy_version": 1.2
}

with apparmor-easyprof-ubuntu 1.3.4 (pending upload), I can successfully create an account under confinement. The reminders app itself is unable to use the account (I can start it, but it never leaves the splash screen). There are some denials:

Title:
  Account plugins should be made confinable by apparmor

Status in tools to review click packages:
  Confirmed
Status in Online Accounts setup for Ubuntu Touch:
  Fix Released
Status in apparmor-easyprof-ubuntu package in Ubuntu:
  Confirmed
Status in ubuntu-system-settings-online-accounts package in Ubuntu:
  Fix Released

Bug description:
  With the current implementation, the QML files for account plugins are
  executed by the Online Accounts QML applet which in turn is executed
  within the System Settings process, which probably means that
  malicious account plugins could control everything that the System
  Settings process can (like entering/exiting the flight mode).

  Account plugins (or the Online Accounts applet itself) should probably
  be run in a separate process, which could then be assigned a stricter
  confinement with apparmor.
