The Chrome-only web future we're heading towards is as proprietary as it gets, and absurdly complex and unfit at the same time for demanding desktop apps people actually would want to use (audio, video, CAD, etc.). Google have successfully infiltrated web standard bodies and competitors to the point these are financially dependent on Google, successfully convincing younger devs that the web is a non-proprietary community effort. As improbable as it sounds, your best bet for a portable desktop app seems X-Windows (1980's tech) or Qtk. Unless you wanted a shitty privacy-invading Web app, or one where the site owner can shut down your app and data at any time.
