III. Purpose of data processing, legal basis, and legitimate interests that are pursued by DE-CIX or a third party, and categories of recipients

1. Surfing on this website

DE-CIX gathers and automatically stores log file information in its server, which your browser deposited with us while you were surfing.

In brief, here is the key data that we store:

  • Type of browser/browser version
  • The operating system used
  • Referrer URL (the page visited previously)
  • URLs / pages on this website that have been accessed
  • IP address of the accessing computer along with its name
  • Time of the server request
  • Visitor history, which we sometimes consolidate with comparable information about other visitors and depict in a form that cannot be personally identified in features like top content.

Furthermore, we record the complete Uniform Resource Locator (URL) clickstream through and from our website, in anonymized form – i.e. the order of the pages on our internet presence that you access, including date and time, cookie or Flash-cookie number, the content that you looked at or that you searched for.

During your visits, we sometimes use JavaScript in order to gather and evaluate information, including the time it takes a website to load, download errors, the duration of the visit on a subpage, information regarding the interaction between pages (e.g. scrolling, clicking, mouse-overs) and leaving the page.

The legal basis for the processing of the IP address is Article 6, Para 1f) of the GDPR. Our legitimate interest results from the following list of purposes of the data processing. Please note on this point that it is not possible for us to draw any direct conclusions about your identity on the basis of the data collected, nor do we attempt to draw such conclusions.

The IP address of your device and the remaining data listed above is used by us for the following purposes:

  • Ensuring a seamless establishment of the connection
  • Ensuring the comfortable use of our website
  • Assessing the system security and stability.

The data is saved for a period of 7 days, after which it is automatically deleted or anonymized. IP addresses are anonymized by deleting the last 3 digits.

Further, we make use of so-called cookies and tracking tools for our website. Exactly what process is undertaken and how your data is used for these is clarified in Section III.8. below.

2. Registration for events

Registration forms for DE-IX’s numerous events are provided in advance on our website. In the scope of your registration, personal data will generally be collected. This includes:

  • Family name
  • First name
  • Company
  • Job title
  • When necessary, billing and delivery address
  • When necessary, billing and payment details
  • Email address
  • When necessary, phone number.

These details are collected for the purposes of identifying and registering you on the day of the event.

The legal basis for this is Article 6, Para 1b) of the GDPR, i.e. you make the data available to us on the basis of the contractual relationship between yourself and us. In addition, regarding the processing of your email address, the German Civil Code requires us by law to send an electronic order confirmation (Article 6, Para. 1c)). Insofar as we do not use your contact details for marketing purposes (see section III.3. below), we store your data collected for the fulfillment of the contract until the expiration of the legal or possible contractual warrantee and guarantee rights. After expiry, we retain the information regarding the contractual relationship that is required by commercial law and tax law for the legally determined period. For this period of time (generally 10 years from the conclusion of the contract), the data will only be re-processed in the case of an audit by the taxation authorities.

Ticket sales for DE-CIX events is undertaken through XING EVENTS GmbH. You can find a link to their Privacy Policy here.

DE-CIX ordinarily creates participant lists for events. The purpose of these is to inform the participants, and these lists are attached to the event documents. The lists usually include the surname, first name, and employer of each of the event’s attendees.

You can withdraw consent to the publication of your personal data in the list of participants at any time, by email to, by post to: DE-CIX Management GmbH, Lichtstrasse 43h, 50825, Cologne (keyword “Data Protection”) or by fax to the number +49 (0)221 70 00 48-111.

The DE-CIX events are also documented on the Internet. This includes the publication of photos or video recordings of the event. The publication of photos and interviews always takes place with the consent of the data subject. 

You have the option at any time to withdraw consent to the use of pictures and video material on which you can be identified as an individual, with effect for the future, by email to, by post to: DE-CIX Management GmbH, Lichtstrasse 43h, 50825, Cologne (keyword “Data Protection”) or by fax to the number +49 (0)221 70 00 48-111.

3. Data processing for marketing purposes

The following information concerns the processing of personal data for marketing purposes. The GDPR declares such data processing on the basis of Article 6 Para. 1f) as conceivable in principle and to be a legitimate interest. The duration of data storage for marketing purposes does not follow any strict precepts and is oriented around the question of whether the storage is necessary for marketing purposes. How this proceeds in the case of the withdrawal of your consent is clarified in section III.3.3.

3.1. Marketing purposes of DE-CIX

Insofar as you have concluded a contract with us regarding participation in an event, we will process your postal contact address apart from of a concrete declaration of consent, in order to occasionally in this way provide you with news on the company or forthcoming events. We process your email address in order to provide you with information regarding our own similar products apart from of a concrete declaration of consent.

3.2. Marketing on the basis of interests

To ensure that you only receive marketing information for which you are putatively interested, we categorize and supplement your customer profile with further information. For this, both statistical information and information regarding your person (e.g. the basic data of your customer profile) is used. The objective is to only provide you with marketing that is oriented to your actual or putative needs and not to burden you with unnecessary marketing.

3.3. Right to withdraw consent

You can withdraw your consent to the data processing for the purposes set out above at any time, without incurring costs, for each channel independently, and with effect for the future. For this, an email or letter to the contact details listed in Section II suffices. There are no costs other than the transmission costs according to the basic tariffs.

Insofar as you withdraw consent, the affected contact addresses will be blocked for further marketing-related data processing. Please note that in exceptional cases, it is possible that further sending of marketing material may take place temporarily, even after receiving your withdrawal of consent. This is technically due to the necessary lead-in time for advertisements and does not mean that we will not comply with your objection. Thank you for your understanding.

4. Sending of newsletters 

You can subscribe to the DE-CIX newsletter on UAE-IX’s website. Within the scope of making a subscription, we will collect personal-related data from you such as name and email address. We shall solely use these types of data for personalization and implementation of our email mailings. In order to prevent the misuse of email addresses, subscribers must confirm the ordering of our newsletter in an automated process via email (double opt-in). Only after you have clicked on the confirmation link will your email address be added to our mailing list. 

Your thus declared consent can be withdrawn at any time with effect for the future. This can be done conveniently with the aid of the link that is located in the lower section of each of our mailings, via email to, or by means of a message to our office – by mail to: DE-CIX Management GmbH, Lichtstrasse 43h, 50825 Cologne, or by fax to: +49-221-7000-48-11.

Our newsletters are sent via that emailing platform MailChimp, operated by the Rocket Science Group, LLC, 675 Ponce De Leon Ave NE #5000, Atlanta, GA 30308, USA. 

When you subscribe to our newsletter, MailChimp stores on our behalf your email address and further data for the sending and analysis of the newsletter. In addition, MailChimp can use this data for the optimization or improvement of their own services, e.g. for the technical optimization of the sending of emails and the presentation of the newsletter, or for commercial purposes, in order to determine which countries the recipients are from. MailChimp does not forward your data to third parties and will not contact you.

The data transfer takes place on the basis of the so-called “EU-US Privacy Shield”. MailChimp’s Privacy Policy can be found here.

The legal basis for the use of the email service provider MailChimp, the undertaking of the collection and analysis of statistical information, and the logging of the subscription process is our legitimate interest as defined in Article 6, Para 1f) of the GDPR. Our interest is directed towards the use of a user-friendly and secure newsletter system that both serves our business interests and the expectations of the user.

After expiry, we retain the information regarding the contractual relationship that is required by commercial law and tax law for the legally determined period.
