III. General information concerning data processing

1. Scope of processing of personal data
We collect and use personal data of our users only to the extent that this is necessary in order to provide a functional website and our content and services. Personal data of our users is generally collected and used only with the user's consent. An exception applies in cases where it is not possible to obtain prior consent for factual reasons and where statutory provisions permit the processing of the data. 

2. Legal basis for processing personal data
Where we obtain a data subject's consent for the processing of personal data, the legal basis is Art. 6 (1) letter a EU General Data Protection Regulation.

Where personal data which is required for the performance of a contract to which the data subject is a party is processed, Art. 6 (1) letter b GDPR serves as the legal basis. This also applies to processing operations which are required in order to implement precontractual measures.

Where personal data must be processed in order to meet a legal obligation to which our Company is subject, Art. 6 (1) letter c GDPR serves as the legal basis.

If the processing is necessary to protect a legitimate interest of our Company or a third party and if the interests, basic rights and fundamental freedoms of the data subject do not override the first named interest, the legal basis used for the processing is Art. 6 (1) letter f GDPR. 

3. Erasure of data and duration of storage
The personal data of the data subject shall be erased or blocked as soon as the purpose of the storage no longer applies. It may be stored beyond said date if this has been stipulated by the European or national legislator in EU regulations, laws or other provisions to which the Controller is subject. The data shall also be blocked or erased if a storage period specified in the said laws expires, unless there is a need to continue to store the data for the purpose of entering into or performing a contract.

4. SSL or TLS encryption
This site uses SSL or TLS encryption for security reasons and to protect the transmission of confidential content, such as requests, which you send us as operator of the site.

You will recognise an encrypted connection from the fact that the browser's address line changes from “http://” to “https://” and from the padlock symbol in your browser line.
If the SSL or TLS encryption is activated the data which you send us will not also be read by third parties.

Data whose continued retention is required for evidentiary purposes shall be exempt from deletion pending final clarification of the incident in question. It may be possible to store it for longer. In this case the IP addresses of the users shall be erased or changed to prevent them from being assigned to the visiting customer.
