This page uses your browsers Local Storage functionality to store MQTT messages whilst they are "inflight". This allows the Paho javascript client to ensure that QoS 1 and QoS 2 messages are successfully delivered even if the network connection or browser fails. If you do not wish for the Local Storage to be used, please do not use this client, or only use QoS 0 to send and receive messages. If you wish to see the data being stored for yourself, open up your developer console and look for the Local Storage section, as messages are sent and received, you will see entries appearing and disappearing as the messages complete their QoS 1 and QoS 2 flows. Messages are deleted as soon as they have completed their QoS flow.
