Responsible for editorial content
Responsible for the editorial content pursuant to Section 18 (2) MStV: Stefan Dzwonek, NexTao GmbH, Königsallee 27, 40212 Düsseldorf, Germany. Every text on this portal is reviewed by the editorial team before publication.
Images and video
The photographs on this portal are licensed stock photography and show models, not members of the editorial team. The short film on the homepage is licensed footage. No image is loaded from a third-party server.
Interactive tools
The tools on this portal calculate estimates from the values you enter and explain how they arrive at them. They are for general information and self-reflection. They do not diagnose, treat or replace advice from a physician, dietitian or qualified therapist. The pictures the tools produce are drawn in your browser from your own inputs; what you do with them is up to you.
Dispute resolution
We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
Liability for content
As a service provider we are responsible for our own content on these pages under general law. We are not obliged to monitor transmitted or stored third-party information or to investigate circumstances that indicate unlawful activity. Obligations to remove or block the use of information under general law remain unaffected. Liability in this respect is only possible from the moment we become aware of a specific infringement. As soon as we become aware of such infringements, we will remove the content in question without delay.
Liability for links
Our pages contain links to external websites of third parties over whose content we have no influence. We therefore cannot accept any liability for this third-party content. The respective provider or operator of the linked pages is always responsible for their content. The linked pages were checked for possible legal violations at the time of linking; unlawful content was not recognisable at that time. Permanent monitoring of the content of linked pages is not reasonable without concrete indications of an infringement. As soon as we become aware of infringements, we will remove such links without delay.
Notes on health topics
The guides and tools on this portal serve general information. They do not replace medical or nutritional advice or an examination. If you have symptoms, please consult a physician.
