3.1     Provision of the website

3.1.0.  Description and scope of data processing

Each time you visit our website, our system, i.e. the web server, automatically collects information from the system of your calling computer or terminal.

The following data is collected by us in this process: 

 3.1.1.  Purpose of data processing

The temporary storage of your IP address by our system is necessary to enable delivery of the website to your device. For this purpose, the user's IP address must necessarily remain stored for the duration of the session. The storage of the above data in so-called log files is done to ensure the functionality of our website. In addition, we use this data to optimize the website and to ensure the security of our information technology systems (e.g. for attack detection). An evaluation of the data for marketing purposes does not take place in this context.

3.1.2.  Legal basis

The legal basis for the temporary storage of this data and the log files is Art. 6 para. 1 lit. f) GDPR (legitimate interests of us as a website operator in the secure, trouble-free and legally compliant provision of the website).

3.1.3. Duration of storage

The above-mentioned data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.

In the case of storage of data in log files, this is the case after 7 days at the latest. Storage beyond this period is possible. In this case, the IP address of the user is deleted or alienated by us, so that an assignment of the calling client is no longer possible and the data contained no longer have any personal reference.

3.2.0. Description and scope of data processing

3.2.3. Duration of storage

The above-mentioned data will be deleted as soon as they are no longer required to achieve the purpose for which they were collected. For personal data sent by e-mail or the contact form, this is the case when the respective conversation with the user has ended. The conversation is terminated when it can be inferred from the circumstances that the relevant facts have been conclusively clarified and no contractual relationship results from it.
