MultiChat Privacy Policy

Last updated: June 13, 2026

      This extension does not collect, transmit, or store any user personal data to external servers. All data is stored locally in your browser only.
    

1. Overview

MultiChat is a Chrome browser extension that allows users to chat with multiple AI services (ChatGPT, Gemini, DeepSeek, Claude, Grok, Doubao) simultaneously in a single page.

2. Data Collection

This extension does not collect any user data.

No browsing history is collected
No personal information is collected (names, emails, IDs, etc.)
No analytics, tracking, or advertising services are used
No external servers or backend APIs
User conversations with AI services are not read, recorded, or transmitted

3. Local Storage

The extension uses chrome.storage.local to store only the following local preferences:

enabledAIs: List of AI services selected by the user
aiPanelSplitSizes: Panel split ratios for the AI window layout

This data is stored locally in your browser only and is never transmitted to any external server. Uninstalling the extension automatically removes this data.

4. iframe Embedding Mechanism

The extension uses Chrome's declarativeNetRequest API to modify HTTP response headers of specific AI service websites:

Removes X-Frame-Options and Content-Security-Policy response headers
This modification applies only to sub_frame resource types and does not affect your normal browsing of these websites
The purpose is to allow embedding these AI services as iframes within the extension page

Content Scripts are injected into the AI website iframes to auto-fill text and click send buttons. All operations are performed locally in your browser.

5. Data Sharing

This extension does not share user data with any third party. User data is not sold or used for advertising.

6. Third-Party Services

The embedded AI services (ChatGPT, Gemini, DeepSeek, Claude, Grok, Doubao) each have their own independent privacy policies and terms of service. Your conversations with these services are governed by their respective privacy policies.

This extension is not responsible for the data handling practices of third-party AI services.

7. Permissions

storage: Saves local preferences (enabled AI list, panel split ratios)
tabs: Routes messages between the extension page and AI service pages
declarativeNetRequest: Removes iframe embedding restrictions on AI service websites to enable core functionality
host_permissions: Limited to the 6 supported AI service domains only

8. Data Security

All data is stored locally in your browser with no network transmission, eliminating data transmission security risks. You can remove all local data at any time by uninstalling the extension.

9. Disclaimer

MultiChat is not affiliated with, endorsed by, or sponsored by any of the supported AI services. Users must register and log into their own accounts on each AI service website. All AI service names and logos are trademarks of their respective owners. Their use in this extension is for identification purposes only and does not imply endorsement.
