Teaching via Zoom
If you are participating in education via Zoom, and this meeting is being recorded, it is because the teacher has deemed it necessary in order to be able to carry out the instruction or examination.
The recording is originally only stored locally on the teacher's computer. The teacher then decides if there is also a need to publish this recording; the standard method of publication for this type of recordings are in Canvas at the space provided for the course in question. It is also the teacher that decides how long this recording will be available; normally this will be as long as the mentioned course space is available in Canvas. Information on publishing should have been given to you as a participant in the meeting - especially if it diverges from the above stated standard procedure. If you have not been given this information, don't hesitate to ask!
