The German version of this page is the binding one. This English translation is provided for understanding only. Read the German version
1. Provider and scope
The provider of Cotrax and the accompanying apps for iOS and Android is CLUSTER ONE GmbH, Grüner Winkel 21, 41065 Mönchengladbach (see the legal notice). These terms apply to the use of the website, the apps and the interface.
2. The service
Cotrax builds practice scenarios for sales conversations – a customer persona together with a set of rules – and assesses the transcript of a conversation held with it automatically. You can hold the conversation in the service itself – over a voice connection to the AI provider, as described in the privacy policy – or at a provider of your choice (such as ChatGPT or Claude). The service is free of charge at present. Daily quotas may apply per account and are then shown in the application. We may adjust scope, quotas and features and may discontinue the service with reasonable notice.
3. Account
An account is needed for the AI features. You sign in with a link sent by email, without a password. You are responsible for access to your mailbox. An account may be used by one person only. You can delete your account in the application at any time; this removes all trainings stored in the account.
4. AI content and transparency
Your conversation partner in the training is an artificial intelligence, not a real person. Replies, assessments and suggestions are produced automatically and can be wrong, incomplete or inappropriate. They are training material and not advice. You can report AI content directly in the apps.
5. Your content
Product knowledge, offer details, files and conversation contributions remain your property. You grant us the right to process this content in order to provide the service and to transmit it to the service providers that the privacy policy lists. Do not upload content you hold no rights to, and no special categories of personal data.
6. Permitted use
The following are not permitted, in particular: attempts to push the AI towards abusive, discriminatory or unlawful content; circumventing quotas or protective mechanisms; automated bulk requests; passing on access credentials. In case of breaches we may block or delete accounts.
7. Availability and liability
The service is provided without any availability commitment. Maintenance and faults at service providers can lead to outages. We are liable without limitation for intent and gross negligence and under the Produkthaftungsgesetz; otherwise only for the breach of material contractual obligations and limited to the foreseeable damage typical for this kind of contract. We give no warranty for the success of real sales conversations.
8. Changes
We may change these terms with effect for the future. We will give notice of material changes in the application or by email. If you continue to use the service afterwards, the changed terms apply.
9. Final provisions
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, mandatory consumer protection provisions of their country of residence continue to apply. The place of jurisdiction for merchants is Mönchengladbach.
