Is it possible to make a local Chrome web app with offline sensible-data storage?

I would like to create a 100% offline web app in Chrome that stores sensible data. Are there any security issues an开发者_高级运维d if yes, which ones?

Thank you

You can't easily make offline apps that are based on file:// urls, you can however create apps that are hosted on a server that are made to work entirely offline.

Read about AppCache, LocalStorage, WebSQL, IndexedDB and FileSystem API's

If you really really don't want to host it, package your code up as a Packaged App
