Last Updated: March 17, 2026

ENUF Enhancer Pro for ChatGPT is a Chrome extension that efficiently manages ChatGPT conversations and projects from a side panel. It provides features such as conversation listing, editing, bulk management, tagging, ZIP export, and prompt submission from the side panel.

This extension respects user privacy. It does not use any analytics tools, advertising SDKs, crash reporting, or third-party tracking services.

Information We Collect

This extension does not collect, track, or transmit any personal information externally.

The following data is retrieved through the chatgpt.com authentication session (Bearer token) and processed in browser memory:

  • Conversation Information: Conversation IDs, titles, creation and update timestamps
  • Message Content: User questions and AI responses, retrieved when displayed in the Chat tab
  • Authentication Token: Bearer token obtained from chatgpt.com's auth session, cached in memory with automatic renewal before expiration

This data is processed only in memory and is not persistently stored in local storage or on any server. It is discarded from memory when the side panel is closed.
