In the case of any ambiguities or conflicts between the German and other language versions of these Terms and Conditions, the German version shall prevail.
These Terms and Conditions (T&Cs) govern the use of the Hanz App (web app and mobile app) and its features by companies or other legal entities (hereinafter referred to as "Company"). The app is provided by GBR Karahodza & Salaheddine, Lerchenstraße 49, 70176 Stuttgart, Germany. The contract is concluded between the provider and the Company. The use of the app by individual employees (users) of the Company takes place within the framework of the rights and obligations assigned by the Company. The users of the app are not direct contractual partners of the provider, but use the app on behalf of and under the responsibility of the Company with whom the provider has entered into the contract.
The Hanz App is a digital platform for managing construction sites. The users (grouped into Managers, Supervisors, and Workers) can create projects, upload construction plans, manage and perform work packages and tasks. The app is solely intended for managing construction sites and must not be used for other purposes.
The contract for the use of the app is concluded between the provider and the Company as soon as the initial user of the Company registers, accepts the T&Cs, and completes the registration. The use of the app by the Company's employees (users) takes place within the framework of the registration made by the Company and the user accounts set up.
The registration is done by an initial user of the Company, who provides their email address and is automatically created as a Manager of the Company. Within a company, users with the roles of Manager or Supervisor can create user accounts for the employees (users) of the Company and assign appropriate roles. A Manager has the highest administrative role and can manage all aspects of the Company within the app. Each employee is considered a "user" in the context of the business use.
The privacy policy can be viewed in the Privacy Policy. By registering and using the app, the Company agrees to the terms outlined there.
Users (employees of the Company) are required to use the app only in accordance with applicable laws and these T&Cs. The Company ensures that all employees use the app solely for the intended purposes in accordance with these T&Cs. It is prohibited to use the app for illegal activities, including but not limited to:
Abuse of the AI services includes, but is not limited to:

Violations of these rules, especially the unauthorized sharing of Worker Codes or the use of shared Worker Codes, may result in the immediate suspension of the user account and potentially legal consequences.
The provider is committed to taking reasonable technical and organizational measures to protect the users' data from unauthorized access, loss, or misuse. The data is stored in a secure cloud infrastructure and a secure database provided by recognized vendors. The Company is responsible for ensuring that its employees comply with data protection regulations.
The provider is not liable for damages or data loss caused by technical errors, system failures, or other circumstances for which the provider is not responsible (e.g., by the cloud database provider or server host).
The provider assumes no responsibility for the content that users store, upload, or share in the app, such as projects, employee information, construction plans, or images.
The provider's liability for damages resulting from the use of the app is, to the extent permitted by law, limited to direct damages. In no case shall the provider be liable for indirect, incidental, or consequential damages.
The use of the Hanz App is currently free of charge. No fee is charged for using the app, and all features are accessible without costs. Price changes will affect the Company as the contracting party.
The provider reserves the right to change the pricing model for the use of the app at any time, even if the app is currently provided for free. In such a case, the provider will inform the Managers of the Company by email about the changes.
The law of the Federal Republic of Germany shall apply. The provisions of international private law and the UN Convention on Contracts for the International Sale of Goods shall not apply.
The jurisdiction for all disputes arising from the use of the app and these T&Cs shall be Stuttgart, provided that the user is a merchant, a legal entity under public law, or a public-law special fund.
If individual provisions of these T&Cs are or become entirely or partially ineffective or unenforceable, the effectiveness of the remaining provisions shall not be affected. The invalid or unenforceable provision will be replaced by a regulation that reflects the economic purpose.
The provider reserves the right to change these Terms and Conditions at any time. All changes will be communicated to the Managers of the Company by email at least 14 days before the changes take effect. The Company is obligated to inform its employees (users) about the changes and ensure that the users accept the modified T&Cs.
If the Company does not object to the modified T&Cs within 14 days of notification of the changes, the changes will be deemed accepted. An objection must be made within 14 days after notification of the changes. In case of an objection, the provider may terminate the contract with the Company. If the Company does not agree to the changes, the provider may suspend the use of the app for the Company.
