In addition to the answers you've already gotten, don't forget standard HTML5 localStorage, which should work across platforms and therefore help code reusability. What's not a standard is how much space you're allowed, but the de facto standard amount is about 5MB in all platforms. It might be more on Windows 8 for Metro style apps, but that's just a guess.
