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 DEON GmbH & Co. KG, Ella-Kay-Str. 22c, 10405 Berlin (hereinafter "DEON“) represents.
Important notice: The validity of this agreement fully replaces all previous versions of this document. These terms apply equally to all third‑party providers, branches, affiliated companies and subsidiaries of DEON, insofar as they are involved in service delivery.
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 Provisioning models:
Freemium: A free basic version for individual users with limited storage and collaboration features.
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 required 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. Providing 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 strictly permitted by law (e.g., to achieve interoperability under 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 features such as semantic knowledge retrieval (RAG), visual grounding (recognition of spatial relationships 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 under no circumstances used 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 (e.g., Germany) during AI processing.
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 verifying and using 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. If misuse is suspected, DEON must be notified immediately.
4.3 Allowed 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 third‑party rights (copyright, personality rights) is strictly prohibited.
4.4 Collaboration (Cross‑Tenant): DEON permits sharing projects across organizational boundaries. The user is responsible for ensuring that when inviting external guests (Guest Users) the internal compliance policies of their 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 usage 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 Late Payment: If a delay of more than 14 days occurs, DEON is entitled to temporarily suspend access to the services until the arrears are settled.
6. Term, Termination and Data Portability
6.1 Contract Term: Subscriptions automatically renew for the selected base term (month/year) unless terminated with a notice period of 30 days before the end of the term.
6.2 Data Export: Users have the right at any time to export their data in common formats (PDF, PPTX, ODP). DEON does not guarantee permanent readability of data after the contract ends.
6.3 Deletion after Termination: Upon the termination becoming effective, all project data will be irrevocably deleted from the servers after a security period of 30 days, unless 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 begin 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 early if the service has been fully provided and you have expressly agreed before the start of execution that you will 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:

8. Warranty, Liability and SLA
8.1 Availability: DEON guarantees an availability of the cloud services of 99,6 % on an annual average. Excluded from this are integrated third-party systems as well as disruptions due to force majeure or failures of upstream providers.
8.2 Liability Standard: 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 via email, post or in‑app notifications within the services. DEON is entitled to amend these terms with a notice period of six weeks. The changes are deemed approved if the user does not object in writing within the 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 Jurisdiction: If the customer is a merchant, a legal entity under public law or a public-law special fund, the exclusive jurisdiction for all disputes arising from or in connection with this agreement is Berlin, Germany.
10.4 Language: This agreement is drafted in German. In case of inconsistencies between this and a translated version, the German version takes precedence.
10.5 Severability Clause: If any provision is ineffective, the effectiveness of the remaining provisions shall not be affected. In place of the ineffective provision, a regulation shall apply that most closely aligns with the original economic purpose and is legally permissible.
