Personal Data

The Chamber of Commerce and Industry Dortmund is a public authority that underlies the regulations of the Data Protection Act of North Rhine Westphalia (DSG NRW) and General Data Protection Regulation (GDPR). According to the DSG NRW personal data is detailed information about personal or objective relations of a specific or identifiable person. For contact purposes, our online presence enables input of the following personal data:

  • Data for a correct address, e.g. title
  • Personal data, e.g. name and surname
  • Address details, e.g. street, postcode and city
  • Communication data, e.g. telephone number, fax number or e-mail address
  • Additional information, e.g. company
  • Profile of the company

Purpose of the collection, processing and use

The personal data named above will exclusively be processed for the following purposes:

  • Contact
  • Enabling our range of services and the necessary communication
  • Handling of possible enquiries
  • Disclosure to interested companies, if you have consented

We would like to point out that you can revoke any consent given to us at any time with effect for the future.

System provider

Our internet service is hosted by the IHK Gesellschaft für Informationsverarbeitung mbH (Limited by German Law), Hörder Hafenstrasse 5, 44263 Dortmund. This service provider collects and stores the following information automatically transmitted by your terminal device:

  • Browser type/version
  • Software used
  • Referrer URL (the previously visited site)
  • IP address of your terminal device
  • Time of the server request

We exclusively use this information for optimization and error analysis. A comparison with other data sets or a transfer to third parties, also in extracts, does not occur. We reserve the right to subsequently check this data in case of suspected illegal use of our website and to pass it on to authorized third parties. After 30 days at the latest the data will automatically be deleted.


Our internet presence uses cookies to provide a convenient and feature-rich online service and to verify your eligibility to use the service. Cookies are text files that contain information to identify recurring customers exclusively for the length of their visit of the website. Cookies are stored on your hard drive and do not cause any damage there.

The website’s cookies contain personal data. Cookies save you the repeated input of data, facilitate the transmission of specific contents and help us identify the especially popular areas of our internet presence. You enable us to steadily improve structure and contents of our internet presence. The following cookies are saved on your terminal device.

TypeNameFunctionStorage duration

You have the possibility to deactivate the acceptance of cookies in the browser of your terminal device. However, we cannot exclude the possibility that all features will be available.

Contact form

If you send us enquiries via the contact form, your details from the enquiry form, including the contact details, will be stored by us for the purpose of processing the enquiry and the event of follow-up questions. We will not pass that data on without your consent.

The processing of the data submitted in the contact form thus exclusively occurs based on your consent (Art. 6 para. 1 lit. a GDPR). You can revoke your consent at any time. To do so an informal notice via e-mail will be sufficient. The legality of data processing operations carried out until revocation remains unaffected by the revocation.

The data entered by you in the contact form will remain with us until you request to delete it, revoke your consent for storage or the purpose for which the data was stored no longer applies (e.g. after processing your enquiry has been completed). Mandatory statutory provisions – particularly retention periods- remain unaffected.

Services by third-party providers

Our internet presence uses contents, services and benefits of third-party providers. These are for example tools for the display of geographical maps or videos. For these services to be made available it is necessary that the IP address of your terminal device is transmitted to third-party providers. Wherever possible, we have chosen a low data protection configuration. We have no influence on whether the IP address is possibly stored. In the following third-party providers are listed.

Display of YouTube videos

On our internet presence we have included videos of the provider YouTube (YouTube LLC, 901 Cherry Avenue, San Bruno, CA 94066, USA, represented by Google Inc. based in 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA). If you are playing the videos, a connection to a YouTube server will be made. Hereby, it will be transmitted to YouTube which one of our websites you have visited.

If you are logged in as a member of YouTube while doing so, YouTube will assign this information to your personal YouTube account. When using this service, such as clicking the start button of a video, this information is also associated with your user account. You can prevent this association by logging out of your YouTube user account and other accounts of the companies YouTube LLC and Google Inc. and by deleting the corresponding cookies of these companies before using our website. You can find further information about data processing and notes on data protection by YouTube under .

By including YouTube videos into our internet presence, cookies may also be set by YouTube.

Social media offerings


For the short message service offered here, the Chamber of Commerce and Industry Dortmund uses the technical platform and services of Twitter Inc., 1355 Market Street, Suite 900, San Francisco, CA 94103, USA. Responsible for the processing of data of people living outside the United States is the Twitter International Company, One Cumberland Place, Fenian Street, Dublin 2 D02 AX07, Ireland.

We would like to point out that the use of Twitter’s short message service is your own responsibility. This particularly applies to the use of the interactive features (e.g. sharing, rating).

You can find information about which data Twitter processes and for which purposes it is used in Twitter’s privacy policy:

The Chamber of Commerce and Industry Dortmund does not have any influence on the type and scope of the data processed by Twitter, the type of processing and use or the transfer of this data to third parties. Also, to that extent it has no means of control. By using Twitter, your personal information will be collected, transmitted, stored, disclosed and used by Twitter Inc. and transmitted, stored and used in the United States, Ireland and other countries where Twitter Inc. conducts business, regardless of your residence. Twitter processes your voluntarily entered data such as name and username, e-mail address, telephone number or the contacts in your address book when you upload or synchronize it. Twitter also evaluates the content you share to determine what topics you are interested in, stores and processes confidential messages that you send directly to other users, and can determine your location using GPS data, wireless network information, or your IP address to send you advertisements or other content.

Twitter Inc. may use analysis tools such as Twitter or Google Analytics for evaluation purposes. The Chamber of Commerce and Industry Dortmund has no influence on the use of such tools by Twitter Inc. and has not been informed about the potential use of such. If tools of this kind are used by Twitter Inc. for the account of the Chamber of Commerce and Industry Dortmund, the Chamber of Commerce and Industry Dortmund has neither commissioned nor approved or otherwise supported this in any way. Nor is the data obtained from the analysis made available to us. Only certain, non-personal information about tweet activity, such as the number of profile or link clicks through a single tweet is available to the Chamber of Commerce and Industry Dortmund via its account. Furthermore, the Chamber of Commerce and Industry Dortmund has no way of preventing or disabling the use of such tools on its Twitter account.

Finally, Twitter also receives information although you have not created an account, if you for example view content. This so-called “log data” may include the IP address, browser type, operating system, information about the previously visited websites, your location, your mobile operator, the device you are using (including device ID and application ID), the search terms you used and cookie information.

You can restrict the processing of your data in the general setting of your account and in the “privacy and security” section. In addition, for mobile devices (smartphones, tablets), you can restrict Twitter’s access to contact and calendar data, photos, location data, etc. in the settings. However, this depends on the operating system used. Further information on these points is available on the following Twitter support pages:

The Chamber of Commerce and Industry Dortmund also processes your data. It does not itself collect any data about your Twitter account. However, the data you enter into Twitter, particularly your username and the content published under your account, will be processed by us to the extent that we may re-tweet or reply to your tweets or may write tweets that reference your account. The data freely published and distributed by yourself on Twitter will thus be included by us in our offer and made accessible to our followers.


Our website contains a “share” button by Facebook Ireland Ltd., 4 Grand Canal Square Grand Canal Harbour, Dublin 2, Ireland. Facebook is a social network. The respective “share”-button can be recognized by Facebook’s logo.

We would like to point out that you use this Facebook page and its features at your own responsibility. This applies particularly to the use of the interactive features (e.g. commenting, sharing, rating).

During the visit of our Facebook page, Facebook records among other things your IP address and further information which exists on your computer in the shape of cookies. This information is utilized to provide us as the operator of the Facebook page with statistical information about the utilization of the Facebook page. More detailed information to this is provided by Facebook under the following link:

The data collected about you in this context is processed by Facebook Ltd. and while doing so may be transferred to countries outside the European Union. Which information Facebook collects and how it is used, is described by Facebook in general terms in its data usage guidelines. There you will also find information on how to contact Facebook as well as information on your advertisement settings.

You can find Facebook’s full data use policy here:

In what way Facebook uses the data from visiting Facebook pages for its own purposes, to what extent activities on the page are assigned, how long Facebook stores this data and whether data from a visit to a Facebook page is passed on to third parties, is not conclusively and clearly stated by Facebook and is unknown to us.

When accessing a Facebook page, the IP address assigned to your terminal device is transmitted to Facebook. According to Facebook this IP address is anonymized (for “German” IP addresses) and deleted after 90 days. Furthermore, Facebook stores information about the terminal devices of its users (e.g. as a part of the logon notification feature); this possibly allows Facebook an association of an IP address to individual users.

If you are currently logged in to Facebook as a user, there is a cookie on your terminal device with your Facebook identification. This enables Facebook to understand that you have visited this page and how you have used it. This also applies to all other Facebook pages. Through Facebook buttons inserted into websites it is made possible for Facebook to register your visits of the websites and to associate them with your Facebook profile. Based on this data, contents or advertising can be offered tailored to you.

To avoid this, you should log out of Facebook or disable the stay signed-in feature, delete the cookies on your device, and exit and restart your browser. This way, information by which you can directly be identified is deleted. With this you can use our Facebook page without your Facebook identification being revealed. If you access interactive features on the page (like, comment, share, messages, etc.), a log-in window will appear. After a possible registration you are visible to Facebook as a certain user.

For information on how to manage or delete existing information about you, visit the following support pages:

The data processing is carried out based on an agreement between joint controllers in accordance with Art. 26 DSGVO, which can be viewed here:

There is a regular review and adjustment of our privacy policy, as it is not possible to make further legal agreements with Facebook.

The Chamber of Commerce and Industry Dortmund also processes your data. Although it does not collect any data itself about your Facebook account. However, the data you enter on Facebook, namely your username and the content published under your account, will be processed by us to the extent that we comment on or reply to your posts, if applicable, or write posts that reference your account. This way the data freely published and distributed by you on Facebook will be included by us in our offer and made available to other users.
