Verantwortlich für den Inhalt nach § 18 Abs. 2 MStV / Responsible for content

Haftung für Inhalte / Liability for content

As a service provider, we are responsible for our own content on these pages under the general laws, in accordance with § 7 (1) DDG. Under §§ 8 to 10 DDG, however, we are not obliged to monitor third-party information that is transmitted or stored, or to investigate circumstances that indicate illegal activity. Obligations to remove or block the use of information under the general laws remain unaffected. Liability in this respect is only possible from the point at which we become aware of a specific infringement. As soon as we become aware of such infringements, we will remove the content concerned without delay.

The course material is written with care, but it is teaching material, offered free of charge, and we give no guarantee that it is complete, current or free of errors.

Haftung für Links / Liability for links

These pages may contain links to external websites of third parties, over whose content we have no influence, and for which we therefore cannot accept any liability. The provider or operator of a linked page is always responsible for its content. Linked pages were checked for possible legal violations when the link was set, and no illegal content was apparent at that time. Continuous monitoring of linked pages is not reasonable without concrete indications of an infringement. As soon as we become aware of an infringement, we will remove the link concerned without delay.

Urheberrecht / Copyright

The course content on this site, including the lessons, exercises, their checks and the accompanying explanations, is original work, created for LevelJar, and is subject to German copyright law. Reproduction, adaptation, distribution or any other use beyond the limits of copyright law requires the written consent of the author.

The site also includes third-party software and fonts, which remain the property of their authors and are used under their own licences, listed under acknowledgements below. If you notice a copyright infringement, please let us know; we will remove the content concerned without delay.

Streitschlichtung / Dispute resolution

We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle).
