<ul>
<li>Answer with your own knowledge base: Use Retrieval-Augmented Generation (RAG) so the chatbot answers from your website content and uploaded documents.</li>

<li>WooCommerce Product Support: Search products, recommend items, and show product cards inside chat.</li>
<li>WooCommerce Cart Actions: Add to cart from chat, refresh cart summary, update quantities, or remove items.</li>
<li>WooCommerce Checkout Assist: Detect checkout requirements, collect required fields, show payment methods, and create an order from chat when your store supports it.</li>
<li>Order Lookup: Surface recent order information for logged-in or identified customers.</li>
<li>WooCommerce-Aware Agent Inbox: Support agents can see useful context such as contact info, last seen page, recently viewed pages, cart snapshot, and recent orders.</li>
<li>Personalized User Context: Logged-in WordPress/WooCommerce users can be recognized automatically for more relevant support.</li>
<li>Live Chat Uploads: Visitors can send images, documents, and voice messages during live chat with staff.</li>

<h3>Privacy Policy</h3>
This plugin transmits the following data to external services operated by Smart Processes:
<ul>
<li>WordPress post and page content (for indexing)</li>

<li>Visitor questions typed into the chat widget</li>
<li>Authentication tokens derived from administrator login (for API authentication)</li>
<li>Customer email and subscription data (for Stripe billing)</li>

<ul>
<li>IP address</li>
<li>User agent (browser and OS information)</li>
<li>Screen resolution</li>
<li>Accepted language</li>

A tab-scoped session ID is stored in <code>sessionStorage</code> and used to keep a conversation alive across refreshes and same-tab navigation. Closing the tab or browser starts a new conversation.
Access tokens and passwords are encrypted at rest in the WordPress database

<h4>Browser Local Storage</h4>
This plugin stores the following data in the visitor’s browser localStorage to preserve UI preferences across page loads:
<ul>
<li>mindweco-theme-mode – stores the visitor’s preferred color theme (light or dark).</li>
<li>pinned_{message_id} – stores which chat messages the visitor has pinned.</li>
<li>cit_{message_id} – stores citation/source references for bot responses.</li>
</ul>
The following values are stored in <code>sessionStorage</code> so the current chat keeps its state only for the active tab:
<ul>
<li>mindweco_tab_session_id – stores the current tab’s chat session ID.</li>
<li>mindweco_conversation_id – stores the active remote conversation ID.</li>
<li>mindweco_ask_only_current_page_{post_id} – stores the state of the Local Thinking toggle per page.</li>
</ul>
All data is stored locally in the visitor’s browser only. None of this data is transmitted to external servers. It is automatically cleared when the visitor starts a new chat session.
The subscription service may also be contacted server-side to retrieve pricing and billing-related information for the plugin’s subscription features.
The Smart Mind website may be referenced for legal pages, product information, optional pricing display, and optional front-end branding links.
