1. Scope of Application
1.1 The following terms and conditions apply between Leadux GmbH, Friedrichstraße 95, 10117 Berlin, Germany ("Leadux") and the customer ("Customer") for the use of the AI-powered conversational lead generation services provided by Leadux ("Services").
1.2 These terms and conditions apply exclusively with regard to the Services. No other terms and conditions shall apply even if Leadux does not expressly object to them.

2.2 The Services are provided as "Software as a Service" (SaaS). The Customer accesses the Services via the internet. Leadux processes and stores data generated through the use of the Services on behalf of the Customer.
2.3 The AI responses generated by the Services are based on the Customer's published website content and general knowledge. Leadux does not guarantee the accuracy, completeness, or suitability of AI-generated responses. The Customer is responsible for reviewing conversation quality and configuring the Services appropriately for their industry and use case.

3.3 The Customer remains the data controller for all personal data collected from their website visitors through the Services. Leadux acts as a data processor on behalf of the Customer. A separate Data Processing Agreement (DPA) governs this relationship.

5. Data Protection
5.1 Leadux processes personal data in compliance with the GDPR and applicable German data protection laws.
