As per the API Guidelines, you are able to take advantage of the HTML localStorage API:

Your application will be able to use the local storage HTML5 API which as a limited amount of space available to your application (5 MB). Please be aware that any state you save here will be local, and hence you won’t be able to restore from it if the user logs into Spotify on another computer and browses to your application.
To restore state regardless of which computer a user is currently using, please use your own backend.

Comprehensive documentation on how you can interact with localStorage can be found on MDC.

It boils down to using window.localStorage.setItem(key, value) and window.localStorage.getItem(key) to set and retrieve data.
