No. Instead of cookies, the LeadDesk Chatbot widget uses browser storage, specifically localStorage and sessionStorage. Together they maintain the chat state and ensure a smooth operation for the chat. If you are using a third party widget, we do not store anything.

 

Comparing cookies and local storage

  Cookies localStroage and sessionStorage
Scope Sent with server requests; shared with the backend Client-side only; not sent with server requests
Size limit ~4KB per cookie ~5-10MB per domain
Lifespan Configurable expiration

localStorage:

  • the data is not deleted when the browser is closed, and are available for future sessions

sessionStorage:

    • lasts for a session
Use Backend communication, tracking
