Privacy Policy

Last updated: April 12, 2026  ·  Claude Chat Exporter v1.0.0

Overview

Claude Chat Exporter is a browser extension that exports Claude.ai conversations to Markdown or JSON files saved directly to your device. It operates entirely locally — no data is ever sent to any external server, and no analytics or tracking of any kind are included.

What the extension accesses

• Page content on claude.ai — The extension reads the DOM of the active Claude.ai conversation tab to find copy-action buttons and the conversation title. This data never leaves your device.
• Claude's internal conversation API — When "Include timestamps" is enabled, the extension makes a single authenticated fetch to claude.ai/api/organizations/…/chat_conversations/… using your existing browser session. This is the same request your browser already makes to display the page. No credentials are stored or transmitted elsewhere.
• Clipboard (temporary intercept) — To capture message text, the extension temporarily intercepts calls to navigator.clipboard.writeText made by Claude's own "Copy" buttons. The interceptor is active only during an export and is fully restored immediately after. No clipboard data is transmitted or stored beyond building the local export file.

What the extension does NOT do

• Collect, transmit, or store any personal data on remote servers
• Use analytics, crash reporting, or telemetry of any kind
• Access any tab other than the active Claude.ai conversation tab
• Run in the background or on any site other than claude.ai
• Require an account, login, or any external service

Data storage

The extension uses no chrome.storage or cookies. The exported Markdown or JSON file is downloaded directly to your local machine via the browser's standard file-download mechanism.

Permissions justification

• activeTab — Required to read the URL of the current tab to confirm the user is on a Claude conversation page before enabling the export UI.
• scripting — Required to inject the export script into the Claude.ai page in order to interact with the page's DOM and clipboard API.
• host_permissions: https://claude.ai/* — Restricts the scripting permission to Claude.ai only; the extension cannot run on any other website.

Changes to this policy

If the privacy practices of this extension ever change, this page will be updated and the version number in the heading will reflect the change.
