Right of objection to data collection in special cases and direct advertising (Art. 21 GDPR*)

In the event of violations of GDPR, those concerned have the right appealing  to a supervisory authority, in particular in the Member State of their residence, their place of work or the place of the suspected violation.


You have the right to have data, we process automatically based on your consent or in fulfilment of a contract, forwarded to you or a third party in a common, machine-readable format.

On our website, a so-called session cookie is automatically generated by the website framework used by us and stored on the end device of the caller when the website is called up. This is usually used, for example, to enable shopping cart functions for a store. The storage of the cookie cannot be avoided with the framework, however, this cookie would also only be able to be used by us and is completely harmless. Currently and for the foreseeable future, we will not use the cookie. Storing a cookie constitutes processing for which we need a legal basis. This is our legitimate interest in using this framework.


Webpage provider do automatically collect and store information in so-called server log files, which your browser automatically transmits to us as follows:

  • Viewed page of accessed file
  • Anonymised IP address
  • Operating system used
  • Browser type and version
  • Referrer URL
  • Host name of accessing computer
  • Date and time of server request
  • IP address
  • Message whether retrieval was successful
  • Amount of data transmitted

This data is not merged with other data sources and recorded as per Art. 6 para. 1 lit. f GDPR*. The website host has a legitimate interest providing  a technically error-free presentation and optimisation of the website – hence, any server log files must be recorded. The IP address is anonymized after 24 hours at the latest and the log entries are automatically deleted after 7 days.

The anonymized data is also evaluated for statistical purposes and to improve the offer. No other use or disclosure to third parties takes place.


If you send us inquiries using our contact form, all your details provided will be stored by us in order to processing your inquiry and for follow-up questions. We do not forward this data without your consent.

Processing of the data entered in the contact form is thus exclusively based on your consent (Art. 6 Para. 1 lit. a GDPR*). You can withdraw this consent at any time by simply sending us an informal notification by e-mail. The legality of data processing operations performed up to the time of revocation remains unaffected by the revocation.

5. processing in dialog

5.1 Contacting us by e-mail

If you contact us by e-mail, the e-mail will be stored by us and used to process your request. We do not pass on this data without your consent. The processing is based on your voluntary consent. Analogous to the section "Contact form", you can revoke your consent.

However, in order to comply with the archiving periods required by law with regard to e-mail traffic relevant under commercial and tax law, we generally transfer incoming e-mails to our e-mail archive. They remain there until the statutory retention periods for the fiscal year expire. The legal basis for this is our legitimate interest in a simple and secure archiving process in conjunction with the statutory regulations relating to commercial and tax-relevant e-mail traffic.

5.2 Application data

If you send us an application, it will always be treated confidentially and protected from unauthorized access. It will be reviewed and decided upon by our human resources managers upon receipt. The legal basis for this is processing with regard to an employment contract, thus Art. 6 para. 1 lit. b DSGVO.

If we can imagine a joint cooperation, we will inform you in detail about the further handling of personal data in your role as an employee in a conversation on site or during the preparation of the contract.

In the other case, we will destroy the documents after six months at the latest. We need this period in order to be able to provide information in the event of subsequent queries or clarifications on your part (legitimate interest according to Art. 6 Para. 1 lit. f DSGVO).

If we are unable to offer you a position directly, but would like to keep you in mind as a candidate for a future position, we would ask for your voluntary consent to do so, which you can revoke at any time.

If you send your application to, your application is excluded from our e-mail archiving.

5.3 Recruiting

Our recruiting employees are regularly on the lookout via social media channels such as XING and LinkedIn for interesting individuals who we might want to recruit as new employees. When we find an interesting candidate, we document some key data about him or her on the publicly viewable profile (e.g., name, current employer, location) as well as information about our exchanges with each other. The legal basis for this is our legitimate interest in finding good and qualified employees. The data will be stored as long as your profile is of interest to us. If we store data about you in this context, we will inform you about it and, if you do not agree, you can object with a simple reply.

6. Social media

Networking and communicating are elementary for us. Of course, you will therefore also find us in corresponding business-oriented social networks. These are currently XING and LinkedIn. The use of these platforms also involves the processing of personal data. We have displayed our company profile on these platforms and use them to introduce ourselves. We use the contact options to exchange information with people, to communicate about us or to advertise jobs. Our legal basis for this is our legitimate interest in being easy to find and reach for you, to get and stay in contact with each other, and to find qualified employees (Art. 6 para. 1 lit. f DSGVO).

However, we do not receive any personal data from the platforms which you yourself cannot also see as a user of the platform. In particular, we do not receive any personal usage statistics or similar data about you from the platforms. We completely delimit processing in this respect. We also have no influence on whether the platforms use mechanisms such as cookies or tracking tools for this purpose. All related topics can be found in the respective privacy policy of the platform:, (regarding the delimitation of the responsibility of the processing in the sense of "jointly responsible party" see

However, you will not miss anything if you do not wish to use these channels - all relevant information about us can be found on this website. You are also welcome to simply give us a call.

7. Processing of data for customer orders

For us as an IT service provider, the processing of personal data in the context of customer orders may play a role. Here, too, the protection of personal data and compliance with the relevant regulations is very important to us. For this reason, we always agree on this point with our customers in the context of a respective commission and are happy to agree on commissioned processing in accordance with Art. 28 DSGVO if necessary.
