Privacy Policy for 英语阅读豆包助手 (English Reading Doubao Assistant) Last Updated: [2026-03-01]

1. Information We Collect and How We Use It The "English Reading Doubao Assistant" (hereinafter referred to as "the Extension") is designed to enhance your English reading and speaking practice using Doubao's AI capabilities. To provide these features, we interact with your browser in the following ways:

• Web Page Content & Screenshots (OCR): When you explicitly initiate a reading session or an OCR (Optical Character Recognition) capture on a web page, the Extension extracts the text or captures a screenshot of the selected active tab. This content is processed locally in your browser using Tesseract.js or sent directly to Doubao (https://www.google.com/search?q=doubao.com) to generate your reading material and context-specific translations.

• Voice Input (Microphone): The Extension utilizes your device's microphone when you click the "Record" (录制) or "Ask" (提问) buttons. The voice data is transmitted directly to Doubao (https://www.google.com/search?q=doubao.com) via their native input fields for speech-to-text conversion and AI evaluation.

• Local Storage (Reading History & Vocabulary): The Extension saves your reading history, learning progress, AI evaluation results, and vocabulary lists locally on your device using Chrome's chrome.storage.local API.

2. Data Sharing and Third Parties

• Doubao (ByteDance): Because the Extension acts as an interface layer over Doubao, the text, voice inputs, and article contents you select for practice are transmitted to www.doubao.com to fetch AI evaluations, translations, and scores. We do not control Doubao's data practices; please refer to Doubao's official privacy policy regarding how they handle the prompts and voice data you submit.

• No Data Selling: We do not collect, transmit, store, or sell any of your personal data on external servers. All extension-specific data (history, settings) remains locally on your device. (Note: Ensure all localhost tracking code is removed before publishing).

3. Permissions Required and Justifications

• storage: To save your reading history, settings, and vocabulary lists locally.

• activeTab & scripting: To extract article text or capture visible areas (for OCR) only on the tabs where you actively invoke the Extension.

• debugger (If you keep it): Used strictly to simulate native keyboard events (Arrow Left/Right) for turning pages on web-based ebook readers that block synthetic DOM events. This is only activated with your explicit in-app consent.

• Host Permissions (*://*.doubao.com/*): Required to inject the assistant UI and facilitate seamless interaction with the Doubao AI chat interface.

4. User Consent and Control You have full control over your data. You can clear your reading history and stored vocabulary at any time via the Extension's settings panel. Voice recording and OCR capturing only occur when you explicitly click the respective buttons.
