– In cases of simple negligence, the Provider is only liable for breaches of essential contractual obligations (cardinal duties), and such liability is limited to the foreseeable damage typical for the contract. Essential contractual obligations are those whose fulfilment is necessary for the proper use of the Platform and on whose observance the user regularly relies.

(7) The Provider assumes no liability for the content or course of group sessions insofar as these serve as a space for exchange and support. Responsibility for the individual implementation of any content and recommendations lies solely with the user.

(8) The group counselling is not designed as psychotherapeutic treatment. Liability for any failure to seek, or delay in seeking, medical or psychotherapeutic help by the user is excluded.
