We do not collect your name, email, browsing history outside the active tab, or any data unrelated to the features above.
2. How Data Is Processed
- Audio transcription: Tab audio and AI tutor voice input are sent to the Groq API (Whisper model) for transcription. Audio is transmitted for processing and is not stored by LinGOAT after transcription completes.
- Translation & AI tutor responses: Transcribed text and selected words/phrases are sent to one or more of the following services to generate translations, definitions, and tutor responses:
- Groq API — translations, AI tutor responses
- Google Translate API — translations
- MyMemory Translation API — translations
- Jisho.org — Japanese word/dictionary lookups
- Wiktionary (en.wiktionary.org) — word/dictionary lookups
- Local storage: Vocabulary lists, starred words, and notes are stored locally in your browser using Chrome's
storage API. This data stays on your device and is not transmitted to us.
3. Third-Party Services
LinGOAT sends data to the following third-party services solely to provide the Extension's core features (transcription, translation, dictionary lookups):
- Groq (groq.com) — audio transcription and language model processing. See Groq's Privacy Policy.
- Google Translate API (translate.googleapis.com) — text translation. See Google's Privacy Policy.
- MyMemory Translation API (mymemory.translated.net) — text translation. See MyMemory's Privacy Policy.
- Jisho.org — Japanese dictionary lookups. Jisho.org is an independent project and does not publish a dedicated privacy policy. You can find more information on their About page.
- Wiktionary (en.wiktionary.org) — dictionary lookups, operated by the Wikimedia Foundation. See Wikimedia's Privacy Policy.
We do not control how these third parties process data beyond fulfilling the specific request sent to them (e.g. translating a sentence, looking up a word). We do not sell, rent, or share your data with any other third party.
4. Data Retention
- Audio sent for transcription is not retained by LinGOAT after the transcript is returned.
