System operator

Our website is hosted by Kontrapunkt Agentur für Kommunikation GmbH, Goldbekplatz 2, 22303 Hamburg, Germany. This service provider collects and stores the following information for us, which your terminal automatically transmits:

  • Browser type/version
  • Operating system used
  • Referrer URL (the previously visited page)
  • IP address of your terminal
  • Time of the server request

We use this information exclusively for optimisation and error analysis. A comparison with other data stocks or a passing on to third parties, also in excerpts, does not take place. We reserve the right to subsequently check these data in the event of suspicion of illegal use of our website and to pass them on to authorised third parties. The data will be deleted automatically after 30 days at the latest.

Third-party services

Our website uses content and services of third parties. These include, for example, tools for sending newsletters and analysing user behaviour. In order for the services to be made available, it is imperative that the IP address be transmitted from your terminal to the third-party provider. Wherever possible, we have chosen a configuration that conforms to data protection regulations. However, we have no influence on whether the IP address may be stored. The third-party vendors are listed below.

Fathom Analytics

Our website uses the services of Fathom Analytics for website analytics. Fathom Analytics does not use cookies and complies with EU GDPR. Your IP address is only briefly processed, and Handelskammer Hamburg, operating this website, has no way of identifying you.

iFrame integration of the Twitter feed

The Twitter feed (Twitter Inc., 1355 Market Street, Suite 900, San Francisco, CA 94103, USA) is integrated into our website. Twitter International Company, One Cumberland Place, Fenian Street, Dublin 2 D02 AX07, Ireland, is responsible for the processing of data of persons living outside the United States.

Twitter uses Twitter buttons or widgets integrated into websites and cookies to record your visits to these websites and assign them to your Twitter profile. On the basis of this data, content and advertising can be tailored and offered to you. Because Twitter Inc. is a non-European provider with a European subsidiary only in Ireland, it is not bound by German data protection regulations in its own reading. This concerns, for instance, your rights to information, blocking or deletion of data and the possibility of objecting to the use of data for advertising purposes.

Social media services


The Hamburg Chamber of Commerce uses the technical platform and services of Twitter Inc. 1355 Market Street, Suite 900, San Francisco, CA 94103, USA, for the short message service offered here. Twitter International Company, One Cumberland Place, Fenian Street, Dublin 2 D02 AX07, Ireland, is responsible for the processing of data of persons living outside the United States.
We would like to point out that you use the Twitter short message service offered here and its functions under your own responsibility. This applies in particular to the use of interactive functions (e.g. sharing, rating).
Information on what data is processed by Twitter and for what purposes can be found in the Twitter privacy policy:

Twitter Inc. is committed to the principles of the EU-US Privacy Shield. More information can be found at:
The Hamburg Chamber of Commerce has no influence on the type and scope of data processed by Twitter, the type of processing and use, or the passing on of this data to third parties. Nor does it have any effective means of control in this respect. By using Twitter, your personal information is collected, transmitted, stored, disclosed and used by Twitter Inc. and is transferred to, stored and used in the United States, Ireland and any other country in which Twitter Inc. does business, regardless of where you live. On the one hand, Twitter thereby processes your voluntarily entered data such as name and username, email address, telephone number or the contacts in your address book when you upload or synchronise it. On the other hand, 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 advertising or other content.
Twitter Inc. may use analysis tools such as Twitter and Google Analytics for analysis. The Hamburg Chamber of Commerce has no influence on the use of such tools by Twitter Inc. and has not been informed about such potential use. If tools of this kind are used by Twitter Inc. for the account of the Hamburg Chamber of Commerce, the Hamburg Chamber of Commerce has not commissioned, approved or supported this in any other way. Nor are the data obtained during the analysis made available to us. Only certain, non-personal information about the tweet activity, such as the number of profile or link clicks through a specific tweet, can be viewed by the Hamburg Chamber of Commerce via its account. Furthermore, the Hamburg Chamber of Commerce has no way to prevent or disable the use of such tools on its Twitter account.
Finally, Twitter also receives information if you view content, for example, even if you have not created an account. This so-called log information may include the IP address, browser type, operating system, information about the previously accessed website and pages, your location, your mobile operator, the terminal you are using (including device ID and application ID), the search terms you are using and cookie information.
You can restrict the processing of your data in the general settings of your Twitter account and under ‘Privacy and security’. In addition, you can restrict Twitter access to contact and calendar data, photos, location data, etc. on mobile devices (smartphones, tablet computers) in the settings options there. However, this depends on the operating system used. More information on these issues can be found on the following Twitter support pages:
You can find out more about the possibility of viewing your own data on Twitter here:
Information on Twitter’s conclusions about you can be found here:
Information on the available personalisation and data protection settings can be found here (with further references):
You also have the option of requesting information via the Twitter data protection form or the archive requirements:
The Hamburg Chamber of Commerce also processes your data. It does not collect any data about your Twitter account. However, the data you enter on Twitter, in particular your username and the content published on your account, will be processed by us in so far as we retweet or reply to your tweets or create tweets ourselves that refer to your account. The data freely published and distributed by you on Twitter will thus be included in our offer and made accessible to our followers.

Data security

Unfortunately, the transmission of information on the Internet is not completely secure, which is why we cannot guarantee the security of the data transmitted to our website via the Internet. We protect our website and other IT systems against the loss of availability, integrity and confidentiality through appropriate technical and organisational measures. Your personal data is transmitted in encrypted form on our website. You can recognise the secure connection by the fact that the displayed address starts with ‘https://...’ instead of ‘http://...’ and a closed padlock is displayed on your browser. For more information about our SSL certificate, click on the padlock.

Your rights and contact information

You can request information at any time about the personal data about you stored by us and, if necessary, its correction and/or deletion and/or blocking. For this purpose and/or for further information, please contact the address given in the Imprint.

If you have any questions, comments or enquiries regarding the collection, processing or use of your personal data by us, please also contact us using the contact details provided. We would like to point out that you can revoke any consent given to us at any time with effect for the future.
