  1. HTML5 Web SQL seems to be abandoned, so I won't bother with that.
  2. Local storage persists "forever" i.e. Until the application or the user explicitly clears the data.
  3. Session storage persists only until the end of browser session(Some browsers persist the data over a crash situation)

Clearing the cache should have no effect on the saved data, but clearing the cookies might destroy it.
