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) extends the workspace with „Holistic Intelligence“. This includes functions such as semantic knowledge retrieval (RAG), visual grounding (recognition of spatial relationships on the board) and automated workflow control via the 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 passwords and API tokens (generated at account.deon.cloud) are stored securely. DEON must be informed without delay if misuse is suspected.
4.3 Permitted content: The user guarantees that the content they upload does not violate applicable law. In particular, uploading malicious code, illegal content or content that infringes the rights of third parties (copyrights, personal rights) is strictly prohibited.
4.4 Collaboration (cross-tenant): DEON allows projects to be shared across organizational boundaries. When inviting external guests (guest users), the user is responsible for ensuring that the internal compliance policies of their own organization are observed.
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 pricing 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.
7. Withdrawal Notice for Consumers
7.1 Right of withdrawal: If you use DEON as a consumer (§ 13 BGB), you have the right to withdraw from this contract within 14 days without giving reasons.
7.2 Consequences of Withdrawal: In the event of a valid withdrawal, all payments already made will be refunded. If you requested that the services start during the withdrawal period, you must pay a reasonable amount corresponding to the portion of services provided up to that point.
7.3 Expiration: The right of withdrawal expires prematurely if the service has been fully delivered and you expressly agreed before the start of execution that you would lose your right of withdrawal upon full contract performance.
To preserve the withdrawal period, timely sending of the withdrawal is sufficient. The withdrawal must be addressed to:
DEON GmbH & Co. KG
Ella-Kay-Str. 22c
10405 Berlin
E-Mail: support@deon.de
8. Warranty, Liability and SLA
8.1 Availability: DEON guarantees an availability of the cloud services of 99.6% on an annual average. This excludes connected third-party systems as well as disruptions caused by force majeure or outages at upstream suppliers.
8.2 Standard of liability: DEON is liable without limitation for intent and gross negligence.
In case of slight negligence, DEON is liable only for breach of an essential contractual obligation (cardinal duty). In this case, liability is limited to the contract-typical, foreseeable damage.
Liability for indirect damages, loss of profit or data loss is – as far as legally permissible – excluded, unless the user has performed regular backups (exports).
9. Indemnification Obligation
The user commits to indemnify DEON from all third‑party claims (including reasonable legal enforcement costs) arising from a culpable breach of these terms of use or applicable law by the user.
10. Final Provisions
10.1 Communication and changes: The user agrees that DEON may communicate with them by email, post or in-app notifications within the services. DEON is entitled to change these terms with six weeks' notice. The changes are deemed approved if the user does not object to them in writing within this period.
10.2 Applicable Law: This agreement is subject to the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods and the conflict‑of‑law rules of international private law.
10.3 Place of jurisdiction: If the customer is a merchant, a legal entity under public law or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from or in connection with this agreement is Berlin, Germany.
10.4 Language: This agreement is written in German. In the event of discrepancies between this version and a translated version, the German version shall prevail.
10.5 Severability clause: Should individual provisions be invalid, this shall not affect the validity of the remaining provisions. The invalid provision shall be replaced by a provision that comes as close as legally permissible to the original economic purpose.
