Privacy Policy — DuolingoFa (دولینگوفا)

What is stored: your settings, your own Gemini API key, a cache of translations and a small history of looked-up words. Everything is kept locally in the browser's extension storage and is never sent to the developer.

What is sent and when: only if you enable the smart features and enter your own API key, the extension sends (a) short interface texts found on duolingo.com pages that are not in its built-in dictionary, and (b) the word, sentence or phrase you select with the 🔎 or 📖 tools (and its surrounding sentence), to the Google Gemini API (generativelanguage.googleapis.com) using your key. Google's terms and privacy policy apply to that processing. Text inside language-lesson exercises (options, word banks, exercise sentences) is not sent automatically.

What is not done: no analytics, no tracking, no advertising, no data sold or shared with anyone else, no remote code.

Permissions: "storage" (settings and cache); access to duolingo.com (to translate the interface); access to generativelanguage.googleapis.com (to call Gemini with your key).
