Lia­bi­li­ty for content

As a ser­vice pro­vi­der, we are respon­si­ble for our own con­tent on the­se pages accord­ing to Sec­tion 7, Para­graph 1 of the Ger­man Tele­me­dia Act (TMG). Accord­ing to §§ 8 to 10 TMG, howe­ver, we as a ser­vice pro­vi­der are not obli­ged to moni­tor trans­mit­ted or stored third-par­ty infor­ma­ti­on or to inves­ti­ga­te cir­cum­s­tan­ces that indi­ca­te ille­gal activity.

Obli­ga­ti­ons to remo­ve or block the use of infor­ma­ti­on accord­ing to gene­ral laws remain unaf­fec­ted. Howe­ver, lia­bi­li­ty in this regard is only pos­si­ble from the point in time at which know­ledge of a spe­ci­fic infrin­ge­ment of the law is known. As soon as we beco­me awa­re of any vio­la­ti­ons of the law, we will remo­ve this con­tent immediately.


The con­tent and works on the­se pages crea­ted by the site ope­ra­tors are sub­ject to Ger­man copy­right law. The dupli­ca­ti­on, edi­t­ing, dis­tri­bu­ti­on and any kind of explo­ita­ti­on out­side the limits of copy­right requi­re the writ­ten con­sent of the respec­ti­ve aut­hor or creator. Down­loads and copies of this site are only per­mit­ted for pri­va­te, non-com­mer­cial use.

Inso­far as the con­tent on this site was not crea­ted by the ope­ra­tor, the copy­rights of third par­ties are obser­ved. In par­ti­cu­lar con­tents of third par­ties are mar­ked as such. Should you nevertheless beco­me awa­re of a copy­right infrin­ge­ment, we ask that you inform us accord­in­gly. As soon as we beco­me awa­re of legal vio­la­ti­ons, we will remo­ve such con­tent immediately.
