mobile local web-server to store local data by a web app

Hi all

scenario:
last year I've developed a web app for android devices that should work off-line.
The app serves as front-end of the main app running on the main web server.
When on-line, the app should receive from the main web server the data about specific tasks that should be done off-line.
When again on-line, the app should return to the main web server the new data of the completed tasks.
In order to work off-line the app stores data in the internal storage of the browser (local-storage or indexedDB).
The application is cached in the Application Cache of the browser (according to the supplied manifest file).
I've not developed a native app for several reason, that cannot be overcame.

new scenario:
the now mandatory use of https does create problems with AppCache; furthermore, the use of the browser internal store seems too limiting and the browser sandbox in general doesn't allow complete operational freedom.
I'm thinking about a solution based on having a web server running locally (on the android device). The web app could talk with a simple server app in order to store and retrieve data in a relational db, and also to carry out other operations such as documents generation and likes.

questions:
what do you think about this, guys?
do you have any hints?
do you know any product (free) that may be used?
maybe a NodeJS running on Android?

I would warmly thank you in advance, guys.

last but not least: please excuse my poor and bad english :(
