IndexedDB isn't sketchy, just annoying. It is the only semi-reliable way to store more than a few MBs of data with JS, but the API is awful and it's a pain to use without some kind of wrapper to make it bearable. (LocalForage is good, it provides a LocalStorage-like API on top of IndexedDB or some other APIs in older browsers.)
