Oratius uses OpenAI to teach. When you ask for feedback, hints or placement, we send your answer, relevant conversation and learning history, and the exercise to OpenAI. If you choose to record speech, we send that recording to OpenAI for transcription. Oratius does not save the recording; submitted text and feedback are saved with your progress. Avoid sharing sensitive personal information. AI can make mistakes. You can withdraw permission in Privacy settings; browsing your lessons remains available.
