(2) The provider of the Platform is:
Stefan Osbahr
Holmer Ring 7
25920 Risum-Lindholm
Germany
Email: kontakt@turnieros.de
(hereinafter "Provider")
(3) Deviating terms of the user are not recognised unless the Provider expressly agrees to their validity in writing.
§ 2 Description of services
(1) TurnierOS is a web-based platform for organising and managing sports tournaments. The Platform offers in particular the following functions: creation and management of tournaments and events, team registration and management, schedule creation and result entry, live result display for spectators, invoicing and payment processing, and communication between organisers and teams.
(2) The Provider makes the Platform available in its current version. There is no entitlement to specific functions or to the maintenance of a specific range of features. The Provider is entitled to further develop, modify or discontinue individual functions of the Platform at any time.
(3) The Provider strives for high availability of the Platform but cannot guarantee uninterrupted availability. In particular during maintenance, updates or events of force majeure, availability may be temporarily limited.
§ 3 Registration and user account
(1) Use of certain functions of the Platform requires registration and the creation of a user account. There is no entitlement to registration.
(2) When registering, the user is obliged to provide truthful and complete information. Changes to the registered data must be updated without delay.
(3) The user is responsible for keeping their login details secret. They are liable for all activities carried out under their user account, unless the use by third parties is not attributable to them. In case of suspected misuse, the Provider must be informed immediately.
(4) The Provider is entitled to block or delete user accounts if the user violates these T&C, has provided false information during registration or if the account is used for illegal purposes.
§ 4 Tournament participation and team registration
(1) Tournament organisers can create tournaments via the Platform and open them for participation. The specific conditions of participation (e.g. age classes, entry fees, number of participants) are determined by the respective organiser.
(2) With the registration of a team for a tournament, a contract is concluded between the team (or its contact person) and the tournament organiser. The Provider of the Platform is not a party to this relationship but merely provides the technical infrastructure.
(3) The contact person who registers a team confirms that they are authorised to represent the team.
§ 5 Terms of payment
(1) If entry fees or other charges apply for participation in a tournament, these are set by the tournament organiser and processed via the Platform. Payment is made via the offered payment service providers (currently Stripe and PayPal).
(2) The payment process is handled directly between the user and the respective payment service provider. The terms of use of the chosen payment service provider apply additionally.
(3) Invoices are provided electronically in PDF format and comply with the requirements of German tax law (ZUGFeRD format).
(4) All prices stated on the Platform are inclusive of statutory VAT, unless stated otherwise.
§ 6 Right of withdrawal for consumers
(1) For distance contracts, consumers have a 14-day right of withdrawal pursuant to §§ 312g, 355 BGB (German Civil Code).
Withdrawal notice:
You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of the conclusion of the contract. To exercise your right of withdrawal, you must inform us (Stefan Osbahr, Holmer Ring 7, 25920 Risum-Lindholm, email: kontakt@turnieros.de) by means of a clear statement (e.g. a letter sent by post or an email) of your decision to withdraw from this contract.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning the exercise of the right of withdrawal before the withdrawal period has expired.
Consequences of withdrawal:
If you withdraw from this contract, we shall reimburse all payments received from you without delay and no later than fourteen days from the day on which we received notice of your withdrawal. For this repayment, we will use the same means of payment that you used for the original transaction, unless expressly agreed otherwise with you.
(2) The right of withdrawal expires prematurely if the contract is for the provision of a service and the service has been fully performed after the consumer has expressly consented to the performance of the service beginning before the expiry of the withdrawal period (§ 356 (4) BGB). This may particularly apply to tournaments taking place before the end of the withdrawal period.
§ 7 User obligations
(1) The user undertakes to use the Platform only for the intended purposes and to comply with all applicable laws when using it.
(2) In particular, the following are prohibited: uploading illegal, insulting, discriminatory or otherwise offensive content; manipulation of tournament results or data; use of automated systems (bots, scrapers) to access the Platform; any action that impairs the functionality of the Platform or hinders other users in its use.
(3) The user indemnifies the Provider from any third-party claims arising from illegal use of the Platform by the user.
§ 8 Liability
(1) The Provider is liable without limitation for intent and gross negligence. For slight negligence, the Provider is only liable in the event of a breach of essential contractual obligations (cardinal obligations). In such case, liability is limited to foreseeable damages typical of the contract.
(2) The above limitations of liability do not apply to damages resulting from injury to life, body or health, to the assumption of a guarantee, or to maliciously concealed defects.
(3) The Provider is not liable for the factual accuracy of tournament data entered by organisers or users. The respective organiser is responsible for the accuracy of tournament results.
(4) The Provider is not liable for outages or disruptions of the Platform caused by force majeure, disruptions at third-party providers (e.g. hosting providers, payment service providers) or other circumstances for which the Provider is not responsible.
§ 9 Intellectual property
(1) All content of the Platform (software, design, texts, graphics, logos) is protected by copyright and is the property of the Provider, unless otherwise marked.
(2) Users are granted a simple, non-transferable right to use the Platform for the duration of use.
(3) Content uploaded by users to the Platform (e.g. club logos, tournament data) remains the property of the respective user. The user grants the Provider a simple right of use to this content to the extent necessary for the provision of the Platform services.
§ 10 Contract duration and termination
(1) The usage relationship is concluded for an indefinite period and may be terminated by either party at any time without notice.
(2) The user may have their account deleted at any time by sending a message to the Provider. The Provider will delete the account and the associated personal data in compliance with statutory retention obligations.
(3) The right to extraordinary termination for good cause remains unaffected.
(4) Upon termination, payment obligations already incurred (e.g. due entry fees) remain in force.
§ 11 Data protection
Information about the processing of personal data can be found in our privacy policy.
§ 12 Changes to the T&C
(1) The Provider reserves the right to change these T&C at any time with effect for the future. Registered users will be informed of material changes by email.
(2) If the user does not object to the amended T&C within four weeks of receiving the notice of change, the amended T&C are deemed accepted. The notice of change will refer to the right to object and the significance of the objection period.
§ 13 Final provisions
(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. In relation to consumers, this choice of law applies only to the extent that it does not restrict mandatory legal provisions of the state in which the consumer has their habitual residence.
(2) If the user is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction for all disputes arising out of or in connection with this contract is Husum.
(3) Should individual provisions of these T&C be or become invalid or unenforceable, the validity of the remaining provisions shall remain unaffected (severability clause).
(4) The European Commission provides a platform for online dispute resolution (ODR): https://ec.europa.eu/consumers/odr/. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
