Purpose: Presentation of the company, provision of services and/or sale of products and communication via the Internet.

The purpose of the data processing on this website is to provide information about the products and services of our companies, combined with the possibility for users to contact the specific contact persons within the company.

In all other respects, we process personal data in accordance with the following legal bases:

  • Art. 6 para. 1 lit. a GDPR for the processing of personal data with the consent of the data subject.
  • Art. 6 para. 1 lit. b GDPR for the necessary processing of personal data for the fulfilment of a contract with the data subject and for the implementation of corresponding pre-contractual measures.
  • Art. 6 para. 1 lit. c GDPR for the necessary processing of personal data in order to fulfil a legal obligation to which we are subject according to possibly applicable EU law or according to the possibly applicable law of a country in which the GDPR is fully or partially applicable.
  • Art. 6 para. 1 lit. f GDPR for the necessary processing of personal data to protect the legitimate interests of us or of third parties, provided that the fundamental freedoms and rights and interests of the data subject do not prevail. Justified interests are in particular our business interests in being able to provide our website, information security, the enforcement of our own legal claims and compliance with further legal provisions.

To this end, we use for the provision of our services service companies that are separately bound to secrecy and data protection. The data will only be passed on to the authorities where overriding statutory regulations exist. Under no circumstances do we use the data collected for the purpose of drawing conclusions about you personally.

  • IP address of your device

  • Name and URL of accessed files

The resulting connection data is automatically deleted, usually for a maximum of seven days. If the website is misused, log data, the further storage of which is necessary for evidence purposes, will be kept until the incident has been clarified.

If you have any questions, we offer you the opportunity to contact us using the form provided on the website. Your name and a valid e-mail address are required so that we know who sent the request and can respond to it. Further information can be provided voluntarily in the free text field.

The data will be processed for the purpose of contacting you in accordance with art. 6 para. 1 sentence 1 lit. a GDPR on the basis of your voluntary consent.

The personal data collected by us for the use of the contact form will be automatically deleted after your request has been processed.


c) With registration / use of our CDS Weblounge / newsletter receipt

On our website you voluntarily have the opportunity to register for our closed web lounge. The personal data you enter there is used for activation, creation of a customer account and registration for our respective newsletter. After submitting the registration form (5 steps), you will receive an automated verification e-mail in which you can complete your registration process by clicking on the link in the e-mail (double opt-in procedure). After completion of this verification procedure, activation by CDS can take place. If you are not activated by CDS, your personal registration data will be blocked and not processed further.

Data processing for the purpose of registration for our web lounge is carried out in accordance with art. 6 para. 1 sent. 1 lit. a and b GDPR on the basis of your voluntary consent, or this is necessary for the fulfilment of a contract with you or for the implementation of a pre-contractual measure.

The personal data collected by us for the use of the web lounge will be blocked after termination of the business relationship or after deletion of your customer account and deleted after the expiry of tax and commercial retention periods.


By registering voluntarily, you also subscribe to our respective newsletter. Consent is obtained during the registration process for the processing of your data and reference is made to this data protection declaration. The legal basis for data processing is art. 6 para. 1 lit. a of the General Data Protection Regulation (GDPR), which allows us to process the data if you have consented to the processing.

Subscription to the newsletter (your consent) can be revoked at any time in the future. To revoke your consent, each newsletter contains a link to unsubscribe from the newsletter. Optionally, you can also unsubscribe directly via our website. A request to unsubscribe from the newsletter can naturally also be sent directly to the person responsible for data processing. This is mentioned under point 1 of this data protection declaration.


Our website uses cookies. Cookies are encrypted text strings that store a website on the user's computer/mobile device. Cookies make it possible to adapt this website to your needs. Cookies are also used to measure the use of various pages on this website. The two types of cookies are referred to as "session cookies" and "persistent cookies". Session cookies are temporary and are automatically deleted as soon as you leave the website. Persistent cookies remain on your computer's hard drive until you delete them. Cookies are not used to collect data about your visits to other sites. Cookies do not damage or impair the functioning of your computer, programs or files.


Our Weblounge uses the following external scripts: Html5shiv and respond.js

Both scripts are used for display purposes in older browsers

HTML5 shiv enables the use of HTML5 editing elements in traditional Internet Explorer and offers easy HTML5 styling for Internet Explorer 6-9, Safari 4.x (and iPhone 3.x) and Firefox 3.x.

Respond.js is a polyfill for minimum/maximum width CSS3 media queries (for IE 6-8 and more). The purpose of this script is to provide a script to enable responsive web designs in browsers that do not support CSS3 media queries.


Your personal data will not be transmitted to third parties for purposes other than those listed below.

We will only pass on your personal data to third parties if:

  • you have given your express consent pursuant to art. 6 para. 1 sent. 1 lit. a GDPR,
  • the disclosure pursuant to art. 6 para. 1 sent. 1 f GDPR is necessary to assert, exercise or defend legal claims and there is no reason to assume that you have an overriding interest worthy of protection in not disclosing your data,
  • in the event that a legal obligation exists for the transfer pursuant to art. 6 para. 1 sent. 1 lit. c GDPR, and
  • this is legally permissible and is necessary for the processing of contractual relationships with you in accordance with art. 6 para. 1 sent. 1 lit. b GDPR.

Use of Matomo Tracking

Purpose of processing

The web analytics service Matomo (Piwik) is used on this website. No cookies are used for this purpose. If you do not agree to the storage and analysis of this data from your visit, you can object to its storage and use at any time by clicking on the following link. In this case, a so-called opt-out cookie will be stored in your browser, which means that Matomo will not collect any session data. Please note that if you delete your cookies completely, the opt-out cookie will also be deleted and you may have to reactivate it.

The legal basis is Art. 6 para. 1 (f) DSGVO. Our legitimate interest results from the fact that we make adjustments for optimisation and marketing purposes as well as for security based on the statistical analysis of user behaviour.
