Privacy Policy for AI Browser Assistant

1. Introduction

AI Browser Assistant ("we", "our", or "the extension") is dedicated to protecting user privacy. This Privacy Policy clarifies how our browser extension collects, uses, stores, and protects your information.

2. Core Principle: Local-First & Zero Tracking

The extension is built with a local-first architecture. All your configuration settings, sensitive credentials (such as API keys), and chat histories are saved solely within your browser's local sandbox via the chrome.storage API.

3. Data Collection and Usage

We process the following data strictly to execute the core functions explicitly requested by the user:

• API Credentials & Custom Endpoints: Your LLM API keys (e.g., OpenAI, Anthropic, DeepSeek, or custom compatible endpoints) are stored locally in your browser. They are used exclusively to authenticate outbound requests to the AI providers you configure.
• User-Selected Text & Page Content: When you invoke translation, article summarization, or side panel analysis, the highlighted text or article body is read from the active tab. This content is sent directly to your chosen AI service solely for generating the requested response.
• Bookmarks: When utilizing the Workspace bookmark management feature, bookmarks are queried and displayed locally inside the extension. No bookmark data is sent to external servers.

4. Third-Party AI Services

When you submit an AI prompt, translate text, or summarize a web page, the necessary text payload is transmitted directly from your client browser to the third-party AI provider endpoint specified in your settings. Please refer to your designated AI provider's privacy policy regarding their data retention and processing standards.

5. Chrome Web Store Limited Use Compliance

We strictly comply with the Chrome Web Store User Data Policy, including the Limited Use requirements:

• We do not sell user data to third parties.
• We do not use or transfer user data for targeted advertising or user tracking across sites.
• We do not use user data to determine creditworthiness or for lending purposes.

6. Permissions Justification

All requested Chrome permissions (e.g., storage, tabs, sidePanel, contextMenus, <all_urls>) are strictly utilized to enable in-page float actions, background synchronization, and native assistant UI as documented in our store declaration.

7. Contact and Inquiries

If you have questions, feedback, or requests regarding this Privacy Policy, please open an issue on our official repository or contact the developer via our support channels:
