We have decided to use Zoom as a videoconferencing service. Note that
this provider (Zoom Video Communications, Inc., 55 Almaden Blvd, Suite
600, San Jose, CA 95113, USA) can access all data that you provide when
registering for the video conference. If you do not provide personal
data during the registration, there is still a possibility that Zoom
identifies you using your IP address. We would not have decided to use
Zoom if we considered this as a significant risk. As an additional
precaution, we have opted to use European computing centers. Should you
still have privacy concerns (and are not using an Internet Service
Provider that cannot map IP addresses to your name), we suggest using an
anonymization service such as Tor (https://www.torproject.org/).
