Unfortunately, you are not able to turn off recordings of online lessons - we’ve always recorded lessons for safeguarding purposes in the classroom and it is part of the terms and conditions to teach on the Tutorful platform. An alternative option would be to turn off your camera during lessons.
It's also important to note that as the recordings are not only a fantastic revision tool for students but also an important method of safeguarding, all session recordings will be accessible by students (or their parents).
