Privacy Policy

Claude SessionKey Helper · Effective 2026-11-06

Claude SessionKey Helper is a browser extension with a single purpose: to read the sessionKey cookie that the user's own browser already holds for claude.ai, display it locally, and copy it to the clipboard when the user explicitly clicks “Copy sessionKey”.

Data the extension accesses

• Only the sessionKey cookie for claude.ai.
• No other cookies, browsing history, tabs, page content, or form data.
• The cookie is read locally through the official chrome.cookies API.

Data collection, storage, and sharing

• The extension does not transmit any data to any server.
• It does not store the key in local storage, sync storage, or a database.
• It does not use analytics, telemetry, advertising, or remote code.
• It does not sell, share, or disclose the key to third parties.

Clipboard

The key is written to the clipboard only after the user clicks the copy button. The clipboard is controlled by the operating system and browser; the extension does not read the clipboard.

Permissions

• cookies — required to read the user's own sessionKey cookie on claude.ai.
• clipboardWrite — required to copy the key when the user clicks the copy button.
• Host permission is limited to https://claude.ai/* and https://*.claude.ai/*.

Retention and deletion

The extension retains no data. To remove access, uninstall the extension. To invalidate a copied key, log out of Claude or revoke the session from Claude's account settings.
