Privacy Policy for DocuCraft

DocuCraft Team

Last Updated: September 18, 2026

Effective Date: September 18, 2026

Thank you for choosing DocuCraft (formerly AI Chat Hub, "the Extension"). We take your privacy very seriously. This Privacy Policy describes transparently how information and user data are handled when you use our browser extension.

1. Core Operating Principle & No External Data Collection

DocuCraft does not operate any external servers, developer databases, analytics services, advertising networks, or remote telemetry.

All document parsing, styling, conversion (Word, PDF, Markdown), and branding synthesis are performed locally within your browser session.
We never collect, transmit, sell, or transfer your conversation content, personal files, or settings to any server owned or operated by the extension developer or third-party tracking services.

2. Permissions and Data Handled Locally

The Extension requests only the minimum permissions necessary to deliver its user-facing features:

storage Permission:
Data Stored: User-configured document branding preferences, including:User-uploaded company logo image (stored strictly as local base64 data URL within chrome.storage.local);
Document title alignment, diagonal watermark text and opacity, footer disclaimer text, and preferred UI language (ui_lang).
Storage Scope: Stored strictly on your local device. Never synchronized to any external cloud or server.
host_permissions (https://chatgpt.com/*, https://chat.openai.com/*, https://claude.ai/*, https://chat.deepseek.com/*, https://gemini.google.com/*):
Purpose: Used strictly to inject the local content script into supported AI web apps upon user visit to parse conversation turns, render the interactive floating action bar, and enable local export.
Website Content & Browsing Activity:The extension reads the conversation content on the active web page exclusively to display dialogue turns and generate your requested Word, PDF, or Markdown export.
The extension checks URL changes within active supported AI tabs solely to reset the selection state when you switch conversation threads (Single Page Application navigation).

3. Local In-Memory Session and Token Security

No Credential Harvesting or Exfiltration: The extension never steals, collects, or exfiltrates user passwords, login credentials, or session tokens.
In-Memory Temporary Handling:The extension's primary extraction mechanism is reading rendered DOM elements directly from the webpage.
In technical scenarios where historical conversation turns are not rendered in the visible DOM, the extension may optionally make same-origin read requests (e.g., using existing session cookies or active session identifiers stored in page memory/localStorage) solely within the official first-party AI platform domain.
Any session tokens accessed for this purpose remain strictly ephemeral in memory during that specific export task. They are never written to external logs, never persisted to disk, and never transmitted outside the official AI platform domain.

4. Third-Party Code and Dependencies

All runtime dependencies (including html2pdf.bundle.min.js, an open-source client-side PDF utility under the MIT license) are 100% locally bundled inside the extension package.
The extension does not load or execute any remotely hosted scripts or external dynamic code, adhering strictly to Chrome Web Store Manifest V3 guidelines.
