2. Independently Operated Websites
Introsinet provides non-commercial web hosting for private individuals and non-profit associations. Websites hosted on individual Introsinet subdomains are operated by their respective owners. Each website provides its own legal notice and privacy policy identifying the party responsible for its content and its processing of personal data.
This legal notice and privacy policy apply only to the central Introsinet website, not automatically to websites hosted on subdomains. Technical hosting and infrastructure-related processing may involve Introsinet and the respective website operator in different roles. These responsibilities, including any necessary data processing agreements, must be determined according to the actual arrangements.

This website may contain links to external websites operated by third parties. Their operators are responsible for their own content and privacy practices. We do not adopt external content as our own merely by linking to it. We will review or remove links when we become aware of a specific legal issue.
