📋 1. Overview

BBC Reading Assistant ("the Extension") is a Chrome browser extension that helps users read BBC news articles by generating AI-powered Chinese summaries and extracting key vocabulary. This privacy policy explains what data the Extension accesses, how it uses that data, and your rights.

We take your privacy seriously. The Extension is designed with a "local-first" principle — your data stays on your device.

🤖 3. Third-Party AI Services

When you analyze an article, the Extension sends the article text and your API request to the AI provider you configured. The following providers are supported:

DeepSeek — deepseek.com (recommended, cost-effective)
OpenAI — openai.com (GPT-4o, GPT-3.5)
OpenRouter — openrouter.ai (multi-model aggregator)
Azure OpenAI — azure.microsoft.com

Please review the privacy policy of your chosen AI provider. The Extension developer has no control over how these providers handle your data.

The Extension does not operate its own backend server. There is no intermediary between your browser and the AI provider you choose.

🔒 4. Chrome Permissions Explained

Permission	Why We Need It
`activeTab`	Read the content of the current BBC article tab when you click "Analyze"

The Extension requests the minimum permissions necessary. It does not have access to your passwords, form data, or any non-BBC pages.

🗂️ 5. Data Retention & Deletion

All data is stored in your browser's local storage (chrome.storage.local). You can delete it at any time by:

Removing individual words from the vocabulary page
