cancellation by Dr. Jochen Tunkel

In this case, any participation fees paid will be refunded. Further claims against the service provider cannot be asserted.
If, due to the corona pandemic, the applicable regulations for events in the respective federal state or at the federal level change, making it impossible to hold the event, we reserve the right to cancel the event at short notice. The course fee will be automatically refunded.

data protection

During the events offered by Dr. Jochen Tunkel / tunkel & tunkel Fachzahnarztpraxis / regenerative bioversity, photographs and video recordings of the event may be made. The aim is to be able to produce an illustrated report on the event afterwards. In doing so, we process the recordings on the basis of “legitimate interests” (Art. 6 para. 1 lit. f DSGVO). Should you wish not to be filmed or photographed at an event itself, please inform Dr. Jochen Tunkel of this during the event.

limitation of liability
We are liable in cases of justifiable inability and justifiable impossibility. Furthermore, we are liable for damages according to the statutory provisions in cases of intent, gross negligence, assumption of a guarantee as well as injury to life, body or health for which we are responsible. If, in addition, we violate with simple negligence an obligation, the fulfillment of which makes the proper execution of the contract possible in the first place and on the observance of which the course participant may regularly rely, as well as obligations, the violation of which endangers the achievement of the purpose of the contract, our obligation to pay compensation shall be limited to the foreseeable damage typical for the contract. In all other cases of liability, claims for damages due to the breach of an obligation arising from the contractual obligation and due to tort are excluded, so that we are not liable in this respect for financial losses of the course participant.
Insofar as our liability is excluded or limited on the basis of the above provisions, this shall also apply to the personal liability of our employees, workers, staff, representatives and vicarious agents. A reversal of the burden of proof is not associated with the above provisions.

If the service recipient is a merchant within the meaning of the German Commercial Code (Handelsgesetzbuch), a legal entity under public law or a special fund under public law, the place of jurisdiction shall be Freiburg im Breisgau. The same shall apply if the Purchaser does not have a general place of jurisdiction in Germany, relocates his/her place of residence or habitual abode outside Germany after conclusion of the contract or if his/her place of residence or habitual abode is unknown at the time the action is brought. However, we are also entitled to sue the customer at his/her general place of jurisdiction.
