Chat Assistant Pro does not collect, store, or share any personal data. The extension processes user‑selected text locally and sends it to the Groq API only when the user explicitly requests an action such as translation, explanation, or summarization. No personal information, browsing history, or identifiable data is collected or stored. All user preferences (robot customization, widget position, settings) are stored locally in the browser using Chrome Storage. No data is sold, shared, or used for advertising purposes.
