Details
The service will check to see if web storage is available on the browser. If it is available then the service will use it to store the key-value items persistently. Web storage can be used in a similar way to cookies but with a much higher size limit (several MB for web storage compared to a few KB for cookies). However, cookies are more widely supported by browsers and can be set to expire after a certain date.
If local storage is not available then non-persistent memory storage within the app is used instead.
