Data protection

We would like to point out that data transmission on the Internet (e.g. when communicating by e-mail) can have security gaps. Complete protection of data against access by third parties is not possible. The following data protection declaration informs you as a user of this website about the collection and use of personal data when visiting and using our websites. It goes without saying that we comply with the statutory provisions on data protection, such as those contained in the German Federal Data Protection Act (BDSG) and the German Telemedia Act (TMG), and we take the protection of your data very seriously. The regulations of the General Data Protection Regulation (GDPR) are observed.

With regard to the data processing described in more detail below, users and data subjects have the right:

To confirmation as to whether data concerning them is being processed, to information about the data processed, to further information about the data processing and to copies of the data (cf. also Art. 15 GDPR);
Correction or completion of inaccurate or incomplete data (cf. also Art. 16 GDPR);
Immediate erasure of the data concerning them (cf. also Art. 17 of the GDPR), or, alternatively, where further processing is necessary pursuant to Art. 17(3) of the GDPR, restriction of processing in accordance with Art. 18 of the GDPR;
To receive the data concerning them and provided by them and to transfer this data to other providers/controllers (cf. also Art. 20 GDPR);
To complain to the supervisory authority if they believe that the data concerning them is being processed by the provider in breach of data protection law (cf. also Art. 77 GDPR).

In addition, the provider is obliged to inform all recipients to whom data has been disclosed by the provider of any correction or deletion of data or restriction of processing that takes place on the basis of Articles 16, 17 (1), 18 DSGVO. However, this obligation does not apply if such notification is impossible or involves a disproportionate effort. Notwithstanding this, the user has a right to information about these recipients.

Likewise, according to Art. 21 DSGVO, users and data subjects have the right to object to the future processing of data concerning them, insofar as the data is processed by the provider in accordance with Art. 6 para. 1 lit. f) DSGVO. In particular, an objection to the processing of data for the purpose of direct marketing is permissible.



General data collection and data processing

Each time the provider’s website is visited and used, the provider or the web space provider collects access data in the form of the IP address and provider of the requesting computer, the website and data accessed, the date and time of access, the volume of data transferred, notification of successful access, the identification data of the browser and operating system used by the requesting computer and the website previously visited (the website from which the provider’s website was accessed).
The collection and processing of the aforementioned access data is only carried out for the purposes of system administration, system security, optimisation of the offer and statistical evaluations. The provider expressly reserves the right to subsequently evaluate the access data in the event of unlawful use and an unlawful attack on the provider’s Internet pages, insofar as there is sufficient suspicion of this on the basis of concrete indications.

Personal data

Concept of personal data
According to Section 3 (1) BDSG, personal data is individual information about personal or factual circumstances of an identified or identifiable natural person. This data includes, for example, name, address, e-mail address or telephone number. Usage data also count as personal data.


Collection of personal data
Personal data is only collected by the provider if this is legally permitted or if you consent to the collection of the data. Consent is assumed by the provider in the event that you contact the provider by e-mail or by means of a contact form; in this case, your data will be stored for the purpose of processing your request. After the processing has been completed, your data will be deleted unless there is a legal obligation to retain it.

The provider stores your IP address if you leave contributions in the blog offered or in any other way offered within the framework of the provider’s Internet offer. You can provide further information voluntarily. The storage is only for the purpose of being able to subsequently allocate contributions that are contrary to the existing legal regulations and thus only serves to safeguard the provider.

You can revoke your consent to the storage of your personal data at any time. You can unsubscribe from subscribed blog posts and subsequent comments at any time.
