Privacy Policy

Effective date: October 16, 2026

Muze AI ("we", "us") provides a browser extension and an associated cloud gateway that let a user connect an AI assistant they choose (such as Claude) to their own web browser. This policy explains what data the extension and gateway access, how it is used, and the choices you have.

Muze AI has a single purpose: to let a user-approved AI assistant read and control the user's browser through a set of permissioned tools, where sensitive or high-impact actions require the user's explicit, one-time approval. We do not use your data for advertising, profiling, creditworthiness, or lending.

Data the extension accesses

The extension only acts in response to a request from the AI assistant you connected, and only for the permissions and tool groups you have enabled. When a tool runs, the extension may access:

• Website content — page text, DOM elements, links, tables, metadata, selected text, and screenshots of the page you are working with.
• Web history — tab URLs and titles, and (only if you enable the history group) your browser history, which the assistant can search or delete.
• Bookmarks, downloads, and clipboard — only if you enable those optional tool groups.
• Account information — the email address associated with your Muze AI account and an authentication token, used to link this browser to the gateway and to show who is signed in.
• Developer diagnostics — console messages, page errors, and performance data for the tab being controlled, when those tools are used.

How the data is used

Data accessed by a tool is used solely to perform the action you requested and to return the result to the AI assistant you connected. For example, if you ask the assistant to summarize a page, the page text is read and returned to that assistant so it can write the summary.

What is shared and with whom

• Your AI assistant. Tool results are sent only to the AI client you connected, so it can carry out your request.
• Our gateway. Requests and results pass through the Muze AI gateway solely to relay them between your browser and your AI client.
• No sale. We do not sell or transfer your data to third parties, and we do not use or transfer it for purposes unrelated to the extension's single purpose.
• No analytics or advertising. The extension contains no analytics, tracking, or advertising SDKs.

Local storage

Your settings (permission configuration) and sign-in token are stored locally in your browser using chrome.storage.local. Clearing the extension's data or signing out removes them.

Retention

The gateway relays tool traffic and does not build a profile of your browsing. Account and session records are retained while your account is active and are removed when you sign out, revoke access, or delete your account.

Security

Traffic between the extension, gateway, and AI client uses HTTPS/WSS. Access tokens are stored hashed on the server side. Approvals and the kill switch let you stop or deny any action at any time.

Your choices and controls

• Enable or disable tool groups from the extension dashboard.
• Approve or deny each sensitive action, or stop everything with the kill switch.
• Sign out at any time to unlink the browser.

Children's privacy

Muze AI is not directed to children under 13, and we do not knowingly collect their data.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by a new effective date on this page.
