Your lectures and notes stay private.
Keep your books and private notes in your account. Uploaded recordings are removed after 30 days.
Your books and saved notes stay available until you delete your account. You can read about storage, deletion, and the services involved in processing below.
Encrypted in transit and at rest
Uploads travel over TLS and are stored encrypted at rest (AES-256) in the cloud. Generated project state and outputs are stored in the same encrypted infrastructure.
Automatic deletion of recordings
Uploaded recordings are deleted automatically 30 days after upload. You do not have to remove them yourself.
You control project data
You can delete your account in Settings. This removes your stored lectures, chapters, private notes, bookmarks, and study tools.
Named subprocessors only
Processing uses a short, disclosed list of subprocessors (below). We do not sell your data or use your recordings to train third-party models.
