+:::note Privacy in Temporary Chats
+In **Temporary Chat** mode, document extraction is performed **exclusively in the browser** to prevent data from being stored or processed on the backend. This strict privacy measure means that some complex file formats (like certain DOCX files) that rely on backend parsers may not be processed correctly.

 ## Available Extraction Methods
 
 Open WebUI supports multiple document extraction engines to accommodate different needs and document types. Each extraction method has its own strengths and is suitable for different scenarios.

+:::warning Temporary Chat Limitations
+When using **Temporary Chat**, document processing is restricted to **frontend-only** operations to ensure your data stays private and is not stored on the server. Consequently, advanced backend parsing (used for formats like complex DOCX files) is disabled, which may result in raw data being seen instead of parsed text. For full document support, use a standard chat session.

 ## Google Drive Integration
 
 When paired with a Google Cloud project that has the Google Picker API and Google Drive API enabled, this feature allows users to directly access their Drive files from the chat interface and upload documents, slides, sheets and more and uploads them as context to your chat. Can be enabled `Admin Panel` > `Settings` > `Documents` menu. Must set [`GOOGLE_DRIVE_API_KEY and GOOGLE_DRIVE_CLIENT_ID`](../../getting-started/env-configuration.mdx) environment variables to use.
