Zoom

Zoom is an alternative, fee-based cloud solution for web conferencing based in the USA. The GWDG has temporarily acquired a limited number of licenses to be able to offer this service as well. Because of this cloud solution where we cannot guarantee our own data security, we typically do not recommend Zoom, especially for highly confidential meetings.

For meetings with less than 20 participants, please use our BigBlueButton service. To be able to offer an alternative solution for BigBluebutton for the lecture period starting 20th April 2020, the University Göttingen and the University Medical Center got a campus license for Zoom

We can create meetings in Zoom for a desired timeslot on request. Until we have an online form for this, you can send a request to webconf@gwdg.de. During our support hours we will set up a corresponding meeting for you as soon as possible.

You can invite participants by sending an email with a URL after setting up a web conference.

Zoom also offers the option to run so-called Meeting Connectors “on premises”, i.e. on servers of the GWDG. The GWDG has an environment for the GWDG (gwdg.zoom.us) and for the University of Göttingen (uni-goettingen.zoom.us). These two environments are currently in test operation. If you would like to participate in this test, please send an email to support@gwdg.de, so that we can activate your account. Click here for further information.

Basically, members of the University of Göttingen use https://uni-goettingen.zoom.us and other users of the GWDG use https://gwdg.zoom.us.

Terms of use

A campus license for Zoom meetings was procured, which covers the University and the University Medical Center Göttingen (employees and students).

The meetings which are included in the campus license are unlimited in time and allow up to 300 participants*. Additional licenses for Zoom webinars and so-called “large meetings” (up to 500 and 1,000 participants, respectively) were procured for teaching events and, if necessary, other, large events. Since the number of these licenses is limited, they will be assigned manually upon request to webconf@gwdg.de. For more information on additional features, please visit the Zoom website:

The following table provides an overview of the Zoom VC variants included in the campus license:

VC variant Description Number of licenses
Meeting Unlimited meetings with up to 300 participants All employees and students of the University and the University Medical Center Göttingen
Large Meeting Meetings with up to 500 participants 300 *)
Webinar 500 Webinars with up to 500 participants 400 *)
Webinar 1,000 Webinars with up to 1,000 participants 10 *)

*) Please send inquiries about this to webconf@gwdg.de.

Zoom is a good tool for teachers, students and learning groups to organize lectures and online meetings. To start or participate in a Zoom meeting, the download and start of a client program is initiated after entering the appropriate URL in the browser window. The software is available for all common operating systems. Alternatively, Zoom can also be used without a client program with an HTML 5-capable browser.


Set up a new Zoom account via the GWDG customer portal

You can create a Zoom account via the Customer Portal of the GWDG (for details see Activation of the zoom account). With this Zoom account, you can already conduct self-scheduled, open-ended meetings with up to 300 participants*.

Please note that by activating your account, you consent to the GWDG transferring your email address, first and last name, and institute affiliation to Zoom (USA) for the use of the service. Data generated during use will be stored on the Zoom servers. Do not use this option if you do not agree to this. Note that the use of the university account is only necessary for the meeting organizer and not for participants. They can also join meetings using the meeting link with an anonymous, self-registered Zoom account.

To use the service with the university account, please log in to the GWDG customer portal and accept the transfer of your data to Zoom in the “External Services” section. Please also refer to our privacy_protection and the online-privacy-policy of the company.


Large meetings or webinars (on request)

On request, we can create individual large meetings or webinars in Zoom with up to 1,000 participants for a desired time slot. Please send your request to webconf@gwdg.de. We will promptly set up a meeting for you during our support hours.


License assignment to create your own large meetings and webinars

We can assign a dedicated license to selected persons, with which any number of large meetings or webinars with up to 500 or 1,000 participants can be set up independently. This offer is primarily aimed at lecturers, IT administrators and/or IT managers. You can also send a request for this by e-mail to webconf@gwdg.de. However, due to the limited number of licenses, the GWDG must reserve the right to review the requests. Nevertheless, no one should be afraid to contact us about this.

The prerequisite for a license assignment is the activation of the zoom account. Subsequently, the respective license can be assigned.


Meetings with Zoom are accessible to everyone via a number identifier (meeting ID). For more security and an undisturbed video conference, the following meeting settings may help:

  • Disable “join before moderator” to prevent third parties from using your meetings without your knowledge.
  • Provide your meetings with passwords that you distribute to the intended participants in advance. To do this, enable the “Require password when setting up new meetings” and “Require password for instant meetings” options.
  • If the “Embed the password in the meeting link for one-click participation” option is enabled, the passwords are encrypted and embedded in the participation link. Provided the links are not distributed publicly, this increases convenience for attendees without seriously compromising security.
  • By enabling the “Request password for phone participants” option, you ensure that meetings are also protected from unwanted participants in this way.
  • If chats (general or private) are not required for a meeting, they should be disabled to prevent the possible unnoticed distribution of unwanted information or malicious web links by participating third parties.
  • If you do not want to transfer files in meetings, you should also disable the corresponding option.
  • The same applies to screen transfer and remote control, if applicable. Annotations and the whiteboard should also be disabled if not required.
  • For ongoing meetings, the “Lock meeting” option can be selected in the client as soon as all participants are present. This prevents unwanted third parties from joining the meeting later and possibly unnoticed.

You can also find more information about security on Zoom's pages:

Zoom also provides further precautions to control a meeting. All of these features are available to the moderator of the meeting.


Privacy Notice

Zoom is provided by a third party provider, the GWDG is only the administrator of the licenses. The use of Zoom requires the transfer of personal data (e-mail address, …) to a third party. The legal basis for this is consent according to DS-GVO Art. 6 Abs(1) Buchst. a). By requesting the GWDG to assign you a license, you are taking the “unambiguous confirming action” necessary for consent.

When using Zoom, we strongly advise against using the “Attention Tracking” feature, as it processes additional participant data and requires both obtaining and proving “verifiable consent” from all participants.

In addition, some reports exist (Heise, Vice) that the Zoom app sends data (time of use, iPhone model, time zone, location, mobile carrier, a unique advertising ID) to Facebook – even if no Facebook account was used to sign up. We continue to monitor the reporting and will update this information as new findings become available.

Data protection information according to DS-GVO Art. 13

This information supplements the data protection declaration of the GWDG (https://www.gwdg.de/privacy-notice) in the necessary places:

University and University Medical Center Göttingen

The collection of personal data is necessary to ensure digital teaching at the University of Göttingen (purpose) and is based on Art. 6 (1) UAbs. 1 lit. e) DSGVO, §§ 3 (1) S. 1 Nr. 1 NHG, 28, 29 PersDatO (legal basis).

As far as recordings are made, the collection of the participants' data is based on consent according to Art. 6 para. 1Ubs. 1 lit. a) DSGVO.

Other users

The processing including the transfer of personal data to Zoom Video Communications, Inc. takes place in the context of the provision of the online service Zoom. Since the use of the service is an additional offer, the legal basis is consent according to DS-GVO Art. 6 para. (1) letter a).

By requesting the GWDG to assign you a license, you hereby perform the “unambiguously confirming act” required for consent.

The right of revocation arises directly from the consent; this is possible in the same way as the consent via the user portal of the GWDG. The other data subject rights (right to information, correction, deletion, blocking, transferability) can be exercised as described in the GWDG data protection statement.

Processed data, recipients of the data, third country status

As part of the Zoom service, the following data is collected and shared:

  • email address, first and last name, institute affiliation (for details see userdata).

The data is passed on to Zoom Video Communications, Inc., a data transfer to the USA can therefore not be ruled out. The USA is a so-called *third country* under data protection law. The EU's PrivacyShield agreement with the USA ensures a data protection standard comparable to the GDPR, but the CloudAct still grants US investigating authorities access to the data in case of doubt.

Storage period

After the end of the subscription by revocation of the user, the customer data will be deleted automatically.

Data security

When using the Zoom service, the Guideline on Information Security of the University of Göttingen must be observed. Every user must be aware that data, e.g. chats, are stored in Zoom. In the case of sensitive data (e.g. personal or financial data), storage on external servers is prohibited.
