Our digital products may only be used online in closed, virtual classrooms of normal size (e.g. via Zoom, Skype, Moodle, etc.) and with the registered participants via screen sharing (sharing their own screen) with course participants. The sessions may not be recorded (filmed), they may not be shared with people outside the classroom, and no screenshots may be made. This virtual use corresponds to the projection / beamer presentation in face-to-face lessons.
Photographing, scanning or other digital copying of our digital products or printed textbooks is not permitted under any circumstances and is a violation of copyright law.
If you have any questions about the use of the materials in online lessons, we will be happy to advise you.
