If the Service User rejects the Alteration Offer, pg5-Studio is entitled to terminate the contract without prior notice, with the result that the Service Account will be deleted immediately. This shall be deemed as a cause of termination for which the Service User is not responsible, so that the legal consequences as stipulated in section (10.11) sentence 1 of this Terms of Service shall occur. Until the effective date of the termination of the contract, the last accepted Terms of Service continue to apply.

9. Liability


The Liability of pg5-Studio for their own as well as their attributable third-party fault for its legal representatives and vicarious agents is limited to intent and gross negligence.

Notwithstanding the foregoing, the liability for injury to life, body and health as well as the liability according to the German Product Liability Act (Produkthaftungsgesetz) shall in all cases fully maintain.

A Liability for minor negligence shall also maintain if it is a matter of essential contractual obligations (Kardinalspflichten) or if pg5-Studio has guaranteed the fulfillment of the breached duty. Essential contractual obligations (Kardinalspflichten) shall be understood as obligations which make the proper execution of the contract possible, obligations whose infringement endanger the realization of the contractual purpose and whose fulfillment the Service User may reasonably trust. However, pg5-Studio is only liable for contractually typical and foreseeable damage with regard to the aforementioned essential contractual obligations (Kardinalspflichten).

  • the Service User uses unauthorized services from pg5-Studio even though he is not allowed to use it because of the above mentioned terms of contract.
  • the Service User otherwise seriously disregards his contractual obligations or continues to disregard the rules of the game.

This does not include the data of the affected Service User as long as and as far as pg5-Studio has an interest in documentation and proof. This applies in particular to accounting documents from the purchase of Premium Services until the relevant statutory period of limitation.


In other cases, the Service User Account is suspended untill the termination date is reached. The account will be deleted automatically after a period of 3 months. (10.8) sentence 2 shall apply mutatis mutandis.


By terminating, the Service User loses all contractual rights by the termination date, in particular all rights to the Digital Contents provided by pg5-Studio.


As far as Premium Content is concerned, the Service User is only entitled to reclaim the amount of money paid, if PG5 Studio terminates for reasons that are beyond the Service User's control. In this case, the money will be repaid to the account deposited by the Service User. Alternatively, the Service User may claim that the Premium Content shall be transferred to another Service Account. Furthermore, for the loss of basic and premium content resulting from the termination of the contract, the service user won't receive any gems, money or transfer possibility to another service account.

13. Data Protection


The Service User agrees to the storage and processing of his data by logging in to the Service Account and the use of the Services for the purpose of opening the Service Account.


If the Service User wishes to delete his / her data, he / she has to inform pg5-Studio by post mail or via email to the address mentioned in (10.5.). In this case, pg5-Studio is entitled to terminate the Service Usage Agreement by good cause, without observing a notice period.
