Data protection

1. Purpose and legal basis of data processing
With this data protection declaration, users receive information about the type, scope and purpose of the collection and use of their data by the responsible provider.

Your personal data will only be processed by us in accordance with the provisions of German data protection law (Article 6 GDPR). Data is personal if it can be clearly assigned to a specific natural person, e.g. name, address, e-mail, telephone number, etc. The legal basis of data protection can be found in the Federal Data Protection Act (BDSG), the Telemedia Act (TMG) and the General Data Protection Regulation (GDPR).

The right to personal data processing arises in particular from
• an existing consent of the user, Art 6 Para. 1 S.1 lit a DSGVO,
• the fulfillment of a contract or pre-contractual measures with the user, Art 6 Para. 1 S.1 lit b DSGVO or
• legitimate interests of the provider, Art 6 Para. 1 S.1 lit f GDPR.

When you access our website, general information is automatically collected. This information (server log files) includes the type of web browser, the operating system used, the domain name of your internet service provider, IP address and the like. This is exclusively information that does not allow any conclusions to be drawn about your person. This information is technically necessary in order to correctly deliver the content you have requested from websites and is mandatory when using the Internet. Anonymous information of this type is statistically evaluated by us in order to optimize our website and the technology behind it. Tracking pixels also serve such purposes. The legal basis for the collection of general information is Art. 6 (1) sentence 1 lit. f GDPR.

2. Responsible in the sense of the data protection laws, Art. 4 No. 7 DSGVO

This website uses the online advertising program "Google AdWords" and conversion tracking as part of this.

Each Google AdWords customer receives a different cookie. This means that cookies cannot be tracked via the websites of AdWords customers.
