B. Specific information

Data protection declaration

We guarantee that we will only collect, process, store and use your data in connection with the processing of your inquiries, as well as for internal purposes, and to provide services or content requested by you.

  • To provide our contractual services (e.g. processing of orders) and online services.
  • Processing is required by law.
  • If you have given your consent.
  • Due to our legitimate interests (i.e. optimization, economic operation and security of our online offer within the meaning of Art. 6/1 lit. f. DSGVO (General Data Protection Regulation), especially when creating profiles for advertising and marketing purposes)

We would like to show you where the above legal bases are laid down in the GDPR:

  • Consent: Art. 6/1 sub-par. a. and Art. 7 DSGVO (GDPR)
  • Processing for the performance of our services and implementation of contractual measures: Art. 6 Par. 1 sub-par. b, GDPR
  • Processing for compliance with our legal obligations: Art. 6 Par. 1 sub-par. c, GDPR
  • Processing for the purposes of our legitimate interests_ Art. 6 Par. 1 sub-par. f, GDPR


Data transfer to third parties

Data will only be passed on to third parties within the framework of legal requirements. We only pass on user data to third parties if this is necessary, for example, for contractual purposes or on the basis of justified interests in the economic and effective operation of our business operations.

If we use subcontractors to provide our services, we take appropriate legal precautions as well as appropriate technical and organizational measures to ensure the protection of personal data in accordance with the relevant legal regulations.

For CODESYS Store customers: All contact data, including e-mail address, surname and first name, are forwarded to Mellissa Data GmbH, Cäcilienstr. 42-44, 80667 Köln, Germany, for verification before activation.

We would like to point out that due to the use of Google Analytics a data transfer takes place when using our online offer.


Transfer of data to a third country or international organization

Third countries are countries in which the GDPO is not directly applicable law. In principle, this includes all countries outside the EU and the European Economic Area.

Data is transmitted to a third country or an international organization. It is taken into account here that appropriate/adequate guarantees are available and that enforceable rights and effective remedies are available to you.


Duration of storage of your personal data

We adhere to the principles of data economy and data avoidance. This means that we only store the data provided to us for as long as necessary to fulfil the aforementioned purposes or as long as the various storage periods provided for by the legislator stipulate. If the re-spective purpose does not apply any more, or after the expiry of the corresponding periods, your data will be blocked or deleted as a matter of routine and in accordance with the statutory provisions.

To ensure this procedure, we have developed an internal company concept.



If you contact us via e-mail or contact form, you agree to electronic communication. In the context of contacting us, personal data is collected. Which data is collected in the case of a contact form can be seen from the respective contact form. Your data will be transmitted SSL-encrypted. The information you provide will only be stored for the purpose of processing your inquiry and for possible follow-up questions.

  • Processing for the performance of our services and implementation of contractual measures: Art. 6 Par. 1 sub-par. b GDPR
  • Processing for the protection of our legitimate interests: Art. 6 Par. 1 sub-par. f GDPR

We use software for the maintenance of customer data (ERP system) or comparable software based on our legitimate interests (efficient and fast processing of user inquiries). The system is operated by us inhouse. No data is therefore passed on to third parties. We would like to point out that e-mails can be read or changed during transmission without authorization and unnoticed. Furthermore, we would like to draw your attention to the fact that we use a software for filtering unsolicited e-mails (spam filter). The spam filter can reject emails that have been falsely identified as spam by certain features.

When you register for our e-mail newsletter, personal data is collected. We use this data for our own advertising purposes in the form of an e-mail newsletter, provided you have expressly consented to this.

Newsletter tracking: If you have expressly consented before, a newsletter tracking tool (also called web beacons or tracking pixels) is used. When the newsletter is delivered, the external server can record certain recipient data, e.g. the time of retrieval, the IP address or information on the e-mail program (client) used. The name of the image file is individualized for each mail recipient by appending a unique ID. The mail sender remembers which ID belongs to which e-mail address and can thus determine which newsletter recipient has just opened the e-mail when retrieving the image.

We use the newsletter tool CleverReach®.
