The short version
You hand us an hour of a lecture. We transcribe it, turn the transcript into notes, a glossary and questions, and hand all four back. The audio passes through us to be processed; it is not written to our storage, and the finished artifacts are held in your own browser. We do not sell your recordings, and we do not hand them to anyone to train models on.
The rest of this page is the detail behind that paragraph. If you want the handling of one specific recording confirmed in writing before you press record, ask at hi@lectureward.com.
