Portal terms of use
These terms of use govern solely the use of the online portal at danubehandwerk.de (the „portal“). They do not govern the provision of the construction services themselves: the respective project works contract between the client company and RB INVEST Project Kft. is always concluded separately and, in all matters relating to services and remuneration, takes precedence over these terms.
1. Scope and contracting parties
The portal is operated by RB INVEST Project Kft., Moha utca 8903/12, 1121 Budapest, Hungary (the „operator“, „we“). Users are (a) client companies that use the portal to handle their projects, and (b) skilled workers who use the portal to record their assignments, working hours and documentation. These terms apply to the use of the portal in the version in force at the time the account is created. Deviating or conflicting terms of a user apply only where we have expressly agreed to them in text form.
2. Purpose and service of the portal
The portal is an internal working tool for organising and documenting trade assignments. In particular, it serves to create and manage construction sites, record and approve working hours, store site and documentation photos, share notices, and coordinate between the client company, skilled workers and administration. The portal is not a public marketplace and does not broker contracts between users.
3. Account, activation and access credentials
Use requires a personal user account. There is no entitlement to the creation of an account; we activate accounts only after prior review. The user must keep their access credentials confidential, not pass them on to third parties, and notify us without delay of any suspicion of misuse. We are entitled to temporarily block or close an account where there is good cause, in particular in the event of a significant or repeated breach of these terms or a justified suspicion of misuse.
4. Users‘ obligations
The user undertakes to provide only truthful and complete information in the portal and to keep it up to date. As part of onboarding, skilled workers truthfully upload the required documents (including ID document, registration and settlement data). The user must not misuse the portal, in particular must not post unlawful content, infringe the rights of third parties, or impair the technical functioning of the portal (e.g. by circumventing security measures or automated scraping). For uploaded content, the user grants us the simple, non-exclusive right, limited to the purpose of the portal, to store and process it and to make it accessible to the parties involved to the extent necessary.
5. Availability of the portal
We endeavour to provide operation that is as uninterrupted as possible, but we owe no particular or uninterrupted availability. Periods for maintenance, further development, disruptions and outages beyond our control (e.g. at the hosting or network provider, force majeure) may limit accessibility. We are entitled to further develop, change or discontinue portal functions, provided this is reasonable for the user.
6. Working hours, approval and documentation
Skilled workers record working hours and documentation in the portal; client companies confirm the reported hours or the completion by way of a digital approval (click confirmation). For evidentiary purposes, the time and IP address of individual actions are logged. The overviews and interim settlements generated in the portal serve transparency and do not replace a tax-effective invoice; binding invoicing takes place outside the portal by the operator. If a user identifies an incorrect entry, this must be reported without delay.
7. Liability
We are liable without limitation for intent and gross negligence, as well as for injury to life, body or health and under mandatory statutory provisions. In the case of simple negligence, we are liable only for the breach of a material contractual obligation (a cardinal obligation whose fulfilment makes the proper use of the portal possible in the first place and on whose observance the user may regularly rely); in that case liability is limited to the foreseeable damage typical for this type of contract. Any liability beyond this is excluded. For the access to the portal provided free of charge, we are additionally liable only in accordance with the statutory limitations of liability. The user remains responsible for appropriately backing up their own data.
8. Data protection
How we process personal data in connection with the portal is described in our privacy policy.
9. Amendment of these terms
We reserve the right to adapt these terms of use with effect for the future, where this is necessary for objective reasons (e.g. a changed legal situation, technical further development, new portal functions) and does not unreasonably disadvantage the user. We will inform users of material changes in an appropriate manner, for example by email or a notice in the portal. If the user does not object within a reasonable period or continues to use the portal, the amended terms are deemed to be accepted; we will point this out separately in the notice.
10. Final provisions
The use of the portal is governed by German law, excluding the UN Convention on Contracts for the International Sale of Goods. If the user is a merchant, a legal person under public law or a special fund under public law, the place of jurisdiction for all disputes arising from the use of the portal is the registered office of the operator; mandatory statutory places of jurisdiction and any mandatory consumer protection remain unaffected. Should any provision of these terms be or become invalid, the validity of the remaining provisions remains unaffected. Amendments and additions require text form.
