+_Note: If the user decides to clear browsing data via whatever mechanism provided by the browser, this will clear out any `cookie`, `localStorage`, or `sessionStorage` stored. It's important to keep this in mind when designing for local persistance, especially when comparing to alternatives such as server side storing in a database or similar (which of course will persist despite user actions)._
