Browser extension privacy

Updated November 9, 2026

The Leash extension helps you connect Leash to your AI, check its security status, review pending requests, and see activity checked by Leash. This disclosure supplements the Leash privacy policy.

What the extension uses

When you sign in, the extension receives a revocable Leash session. It uses your account identity, AI connection metadata, pending approval details, and recent Leash activity to provide the control panel. Installation assistance reads the relevant buttons, labels and connection fields on the supported AI page you choose. The current site's address is used locally to identify the AI.

The extension does not collect your browsing history, scrape your chat conversations, sell data, use advertising trackers, or load remote executable code. It does not receive your Google, Apple or Microsoft password.

Your choices

Access to supported AI sites is optional and requested when you choose to connect that AI. Browser notifications are optional. Notifications contain a general description, not email contents or other private account details. Connecting email, files and other data accounts requires separate consent in Leash.

Storage and transmission

The sign-in session is stored in Chrome extension storage restricted to trusted extension pages. Private installation links and cached activity use extension session storage, also restricted to trusted extension pages. Content scripts cannot read that storage or approve requests. Sign out to revoke the extension's session and clear its cached data. Leash sessions expire after 30 days unless ended earlier.

The extension communicates with Leash over HTTPS. During setup, your private MCP connection is entered into the AI's connection settings so that AI can use Leash. No conversation transcript or general browsing history is sent to Leash by the extension. Leash account and activity retention follow the main privacy policy.

Limited use

Use of data received through the extension complies with the Chrome Web Store User Data Policy, including its Limited Use requirements. Data is used only to provide and maintain Leash's disclosed AI setup and security-control features.

Remove access or delete your account

Sign out in the extension, remove a site's permission in Chrome, or uninstall the extension at any time. Removing the extension does not disconnect an AI you separately installed. Manage AI connections and use Delete account in your Leash account to remove your account and associated data under Leash's deletion policy.
