With the right-click menu, only the text you selected on a page, when you choose “Practise this with Yiju”; it reads nothing else on any page and runs no script on any page. Your microphone only while you have a voice call open, and the API keys you enter in Settings. **Where it is kept.** Only on your own computer: in the browser's extension storage (with cached speech audio in the browser's IndexedDB) for the extension, or the app's `studio/data/` folder for the local server — API keys, settings, practice records (your text, the prepared material, what you wrote, feedback, explanations, voice transcripts), Anki cards waiting to be pushed, and model usage. The developer cannot see any of it. Uninstalling the extension (or deleting `studio/data/`) deletes it all. **Who receives it.** To provide its features, 一句 sends the necessary content, with **your own API key**, directly to **the providers you choose** in Settings — Google (Gemini API), DeepSeek, or Alibaba Cloud Model Studio (Qwen) — and to no one else: your text and focus for preparing the material; the sentence's meaning, the prepared wording and what you wrote for checks, hints, reviews, quizzes and explanations; the words to be read aloud when Gemini speech is chosen (with the browser's own voices chosen, the browser reads them — some of Microsoft Edge's “natural” voices send the text to Microsoft's service); your microphone audio and the current sentence's context during a voice call. Anki cards, if you turn that on, go only to Anki on your own computer (AnkiConnect at `127.0.0.1`). Each provider's own terms and privacy policy apply to what it receives. Your data is not used for any other purpose and is not transferred to anyone else. **Children.** 一句 is meant for learners. If you are under 14, use it with your parent's or guardian's consent and guidance, and follow the age requirements of the provider you choose. **Changes and contact.** Changes will be posted on this page with a new effective date.
