Introduction and Scope
This document constitutes a comprehensive and legally binding agreement between the customer (hereinafter „Customer“ or „You“ – a legal entity or individual using DEON services) and the DEON GmbH & Co. KG, Ella-Kay-Str. 22c, 10405 Berlin (hereinafter „DEON“).
Important notice: The effect of this agreement fully replaces all previous versions of this document. These terms apply equally to all third parties, branches, affiliated companies and subsidiaries of DEON, insofar as they are involved in the provision of services.
DEON acts as „Sovereign AI Workspace“ and provides an infrastructure that goes beyond conventional whiteboard applications. The term „User“ refers to all persons who are authorized by the customer (e.g., by assigning a „Seat“ in the admin backend) to access DEON. „DEON“ includes:
- Platform services (SaaS/Cloud): Operated under deon.de, deon.eu, deon.cloud as well as customer-specific subdomains.
- Client Software: The installable applications for Windows (WPF/XPF), macOS, iOS as well as the web client (Lite/Desktop).
By registering an account, installing the software, or actively using the services, you fully agree to these terms.
1. Subject of the contract and scope of services
1.1 The Visual Workspace:
DEON provides a visual collaboration platform that acts as a universal data aggregator. The platform enables spatial organization of unstructured information (images, documents, notes) and interaction with over 40 file formats (including PDF, Office, CAD screenshots, high-resolution videos).
1.2 Meta-Browser Technology:
A core feature is the embedding of fully functional web browsers directly into the workspace. This allows the interactive use of third‑party applications (e.g., Jira, SAP Fiori, Salesforce) within the visual context without a media break.
1.3 Deployment models:
Freemium: A free basic version for individual users with limited storage and collaboration functions.
Enterprise/Pro: Paid subscriptions with extended administration rights, SSO integration, and unlimited projects.
1.4 Infrastructure and sovereignty:
The standard cloud service is operated GDPR-compliant on a Microsoft Azure infrastructure (West Europe). To meet the requirements for maximum data sovereignty (especially for the public sector), DEON optionally offers operation in sovereign European clouds (e.g., IONOS, STACKIT, Azure C5 Type 2) or as a fully isolated on-premises installation. These sovereign options may be subject to separate service descriptions and pricing models.
1.5 Continuous development:
DEON reserves the right to continuously expand the functionality (e.g., new AI agents, improved rendering engines). Updates serve security, stability and interoperability. Significant restrictions of existing functions will be announced with a 30‑day notice period.
2. End‑User License Agreement (EULA)
2.1 Usage rights: DEON grants the user a time-limited, revocable, non-exclusive right to install and use the client software. This license applies to the contractually agreed number of devices per user.
2.2 Update Obligation: To ensure data security, the user is obliged to install offered client updates promptly. DEON uses automated update mechanisms to ensure compatibility with the cloud components.
2.3 Reservation of ownership: All copyrights, patents and trademark rights to the software remain with DEON. The provision of the software does not constitute a sale of intellectual property rights.
2.4 Prohibited Use: Any form of reverse engineering or attempts to extract the source code are prohibited, unless expressly permitted by law (e.g., to achieve interoperability pursuant to the Copyright Act).
The use of automated scripts to extract data from the Workspace (“Scraping“) is only permitted through the officially documented REST APIs.
3. AI Functions (DEON Holistic Intelligence & DAIA)
3.1 Definition: The AI integration (DAIA – DEON AI Assistant) expands the workspace with „Holistic Intelligence“. This includes features such as semantic knowledge retrieval (RAG), visual grounding (recognition of räumlicher Zusammenhänge on the board) and automated workflow control via Model Context Protocol (MCP).
3.2 Data processing and Privacy (Zero-Training-Policy):
No use for model training: Customer-specific data, prompts and AI responses are not used under any circumstances for training base language models (LLMs) of DEON or third‑party providers (OpenAI, Google, Microsoft, STACKIT).
Local Inference: When using sovereign cloud options, the data remains within the defined legal jurisdiction during AI processing (e.g., Germany).
3.3 DAIA Agents: Users can create specialized „DAIA agents“ that are limited to specific project knowledge. These agents act as experts for defined subject areas (e.g., „Project Archive Agent“).
3.4 Disclaimer for AI results: AI-generated content is provided „as is“ . Due to the nature of LLMs, results can be factually incorrect or incomplete („hallucinations“).
Human in the Loop: The user bears sole responsibility for the verification and use of the results generated by DAIA. AI outputs should never serve as the sole basis for business‑critical or safety‑relevant decisions.
4. Registration, Identity and User Obligations
4.1 Identity Management: Authentication is performed primarily via Keycloak. This enables enterprise customers to seamlessly integrate their own identity providers (SAML/OIDC). The customer is responsible for managing its users in the DEON admin backend.
4.2 Security of credentials: The customer ensures that Passwörter and API-Tokens (generated under account.deon.cloud) are stored securely. If abuse is suspected, DEON must be informed unverzüglich.
4.3 Zulässige Inhalte: The user guarantees that the content uploaded by them does not violate applicable law verstoßen. In particular, uploading malicious code, illegal content, or content that infringes third‑party rights (copyrights, Persönlichkeitsrechte) is strictly prohibited.
4.4 Collaboration (Cross-Tenant): DEON allows sharing of projects über organizational boundaries. The user is für responsible that when inviting external Gäste (Guest Users) the internal compliance guidelines of the own organization are maintained.
5. Fees, AI Credits and Payment Terms
5.1 Subscription Fees: The costs are based on the current price list or individual framework agreements. All prices are exclusive of statutory VAT.
5.2 AI Credit System: Certain AI interactions consume „Credits“ (based on token consumption and model complexity).
Each paid subscription includes a monthly inclusive quota. Unused credits expire at the end of the billing period.
Additional credits can be purchased at any time as “Top-Up“. Enterprise customers can agree on alternative billing models (e.g., “Bring Your Own Endpoint“ for VW LLM-as-a-Service).
5.3 Payment Delay: If a delay of more than 14 days occurs, DEON is entitled to temporarily suspend access to the services until the outstanding amount is settled.
6. Term, Termination and Data Portability
6.1 Contract Term: Subscriptions automatically renew for the selected base term (monthly/yearly) unless terminated with a 30‑day notice before the end of the term.
6.2 Data Export: Users may at any time export their data in common formats (PDF, PPTX, ODP). DEON does not guarantee permanent readability of data after contract termination.
6.3 Deletion after termination: Upon the effective date of termination, all project data will be irrevocably deleted from the servers after a security period of 30 days, provided no statutory retention obligations apply.
