6. Liability for content

6.1 Content of this website

We prepare the content of this website with care. We do not warrant that it is complete, correct or up to date at all times. Mandatory liability under the law is unaffected.

6.2 Chat content

reactive.chat provides the technical platform for conversations between our Customers and the visitors of their websites. We are not a party to these conversations. Messages of a Customer's agents and of its AI assistant are statements of that Customer; messages of visitors are statements of the visitor. We do not review messages editorially. Automated measures apply: before a chat message is stored, card numbers, IBANs, e-mail addresses, telephone numbers written with a leading + or 0, German tax and identity-card numbers and secrets are replaced by placeholders (not in data sent through the programming interface or entered in chat forms), and spam and abuse are detected automatically. As a hosting provider we are not obliged to monitor stored information; we act on specific notices.

6.3 Knowledge base and AI answers

The knowledge base from which a Customer's AI assistant answers is created and maintained by the Customer. Its accuracy, lawfulness and the rights to it are the Customer's responsibility. AI answers are generated from this content by language models running on our own computers; they can be wrong. We are responsible for the selection, configuration and operation of the models, not for the content of the Customer's knowledge base. The Customer must review the assistant's behaviour and can switch it off at any time. Details: AI Act information.

6.4 Reporting illegal content

If you encounter illegal content in a chat operated with reactive.chat, report it to contact@lukaswojcik.com, stating where you found it and why you consider it illegal. We examine every report and act as described in the Acceptable Use and Anti-Abuse Policy.

7. External links

This website contains links to websites of third parties. We have no influence on their content; the respective operator is responsible for it. At the time of linking no illegal content was apparent. If we become aware of an infringement, we remove the link.

8. Copyright and licences

The content of this website and the software of reactive.chat (texts, graphics, code and design) are protected by copyright. Any use beyond reading, in particular reproduction, editing and distribution, requires our prior written consent. Names and marks of third parties belong to their respective owners.
