Introduction
This document represents an agreement between the customer (a legal entity or individual using the DEON services) and DEON GmbH & Co. KG. The term "user" refers to individuals authorized by the customer to access and use DEON. The agreement also applies to companies associated with DEON.
"Deon" refers to the services and programs offered by DEON under the domains operated by DEON (deon.de, deon.eu, deon.cloud, etc.) and their subdomains as well as aliases.
By operating and using Deon, you accept the terms of this agreement. You commit to using Deon exclusively in accordance with the following terms.
These terms of use become part of the contract when the user registers for Deon, accepts an offer from DEON, or otherwise uses DEON services. During registration, explicit consent is obtained. The same applies when DEON services are commissioned in writing.
1. Subject of the Contract
DEON provides a collaboration platform (“Deon”) that allows visual projects to be created and managed in shared workspaces.
Deon is available as a freemium service: The free version includes limited functionality and usage capacity, while paid subscriptions unlock additional features and higher limits.
The fees for using Deon are communicated to the user in writing and are binding. These fees are due immediately after invoicing for the entire term and can be paid using the specified payment method. DEON can send invoices and payment reminders via email. If a fee cannot be collected, the user bears all resulting costs.
Deon may only be used within the scope of the offered possibilities. All other uses require the prior written consent of DEON.
With Deon, DEON provides a technical application for the exchange of content and collaboration among users. DEON does not participate in the content.</a>
The user acknowledges that a 100% fail-safe provision of applications is not possible and that the provision may be hindered by internal events (e.g. maintenance work, security interests) and external events (e.g. power and network outages). This also applies to Deon. However, DEON will endeavor to achieve the highest possible system stability and constant availability for the services offered.
Deon, all elements contained therein and all associated content - with the exception of user transfers and unless otherwise specified - belong to DEON or are licensed to DEON. All copyrights and other industrial property rights, regardless of their form, remain at all times with DEON and the licensors of DEON.
DEON reserves the right to make changes to the services and other performances offered, provided this is reasonable for the user.
2. Rights and Obligations of the User
You may use Deon for your own purposes (“use” means access to and execution of the services and programs offered).
Completing the registration process constitutes an offer on your part to enter into an agreement on the use of Deon. DEON accepts this offer by setting up your user account. This acceptance means that the agreement between you and DEON has been concluded.
To register as a user, you must provide personal data that must be truthful. We recommend that you keep your password confidential to prevent misuse. Each user may register only once and create only one user profile.
The customer grants DEON the right to include the customer's name and company logo in its customer list and website. Apart from this, neither party may use the name or logo of the other party without their prior written consent.
Please note that you are responsible for your activities on the platform. Any liability for these actions on the part of DEON is excluded.
You are obliged to comply with the laws applicable in your country for the entire period during which you use Deon, especially when configuring content and communicating with other users.
In addition and regardless of the legal situation, you are not permitted to:
- To use content that is pornographic, vulgar, obscene, abusive, insulting, defamatory, harassing, threatening, hateful, racist, or otherwise objectionable;
- To harass other users with mass content (especially SPAM).
In addition, the following actions are prohibited for all users, unless otherwise agreed contractually:
- To rent, lease, sublicense, lend, sell, transfer, copy, modify, adapt, connect with other programs, translate, convert into another programming language, perform reverse engineering of the various manufacturing steps of the software, decompile or create derivative works of Deon or elements of Deon, either by itself or through third parties, unless this is expressly permitted in this Agreement or by mandatory law.
- To copy or trade Deon or elements of Deon in any way or to permit third parties to do so, unless this is expressly permitted in this agreement.
- To activate Deon or elements of Deon with mechanisms, scripts, or other software (e.g., robots or crawlers) that are not required for the proper use of the platform. However, this does not affect the use of interfaces and software provided by DEON for programmatic access (e.g., APIs).
- To carry out activities that negatively affect or excessively burden the function and/or infrastructure of Deon.
If you notice that other users are using Deon in an illegal or non-contractual (improper) manner, you can notify DEON via the platform's contact form.
3. AI-supported functions
Overview
DEON can introduce optional features supported by artificial intelligence (“AI features”) designed to assist users in creating, organizing, or analyzing content.
Activation (Opt-in / Opt-out)
The use of AI functions is entirely voluntary. They are disabled by default and can be activated by individual users or the customer's organization administrator ("Opt-in“). Users can deactivate them at any time ("Opt-out“).
AI Provider
When activated, AI features can process user-provided content via one or more external AI service providers (“AI Provider”) on behalf of DEON.
DEON carefully selects AI Providers and ensures compliance with the EU General Data Protection Regulation (GDPR) through corresponding data processing agreements.
The current list of AI Providers (including their processing locations and data transfer protection measures) is available at:
https://deon.de/document/ai-providers
This list can be updated at any time without requiring a new version of these Terms.
Data Usage and Responsibility
When AI functions are used, user input data and AI-generated outputs may only be processed to provide the requested result. DEON and its AI providers do not use this data for model training unless explicitly agreed upon.
You must ensure that no unlawful or confidential data is transmitted unless you are authorized to do so.
Outputs and accuracy
AI-generated results are created automatically and may contain inaccuracies. They are provided "as is" without warranty of accuracy, completeness, or suitability for a particular purpose.
Ownership
You retain the rights to your inputs and AI-generated outputs, unless such content contains third-party material. DEON does not claim ownership of your content.
Credits and Billing
AI functions may be subject to usage limits, credits, or additional fees. Each user can receive a free monthly credit and purchase additional credits as needed. Details are available in the plan-specific terms.
4. Term and Termination
Free services can be terminated by the user at any time without giving a reason. The user can cancel directly via the account page. After cancellation, DEON can delete all content created by the user.
Paid services are provided on a subscription basis. Renewal and cancellation periods depend on the specific plan. The user can view, modify or cancel the subscription at any time via the account page, subject to the cancellation period applicable to the chosen plan. After cancellation, DEON can delete all content created by the user.
Both parties are entitled to terminate both free and paid services for good cause. Good cause exists if, taking into account all the circumstances of the individual case and weighing the mutual interests, it is unreasonable to continue the contractual relationship until the agreed termination or until the expiry of a notice period. Good cause exists in particular if:
The user does not comply with statutory provisions;
The user breaches provisions of this agreement;
The user harms other users or the platform.
If good cause exists, DEON is entitled, in addition to termination, to warn the user, delete the user's content and block the user's access.
The user's claim to a refund of fees paid in advance expires if DEON must take measures that result from the existence of good cause.
5. Right of Withdrawal for Consumers
If you use Deon as a consumer within the meaning of the law (§ 13 BGB), the following conditions apply to you: Right of withdrawal: You can revoke your contractual declaration within 14 days without stating any reasons in text form (e.g. letter, e-mail). The period begins after receipt of this instruction in text form, but not before conclusion of the contract and not before fulfillment of our information obligations according to Article 246 § 2 in conjunction with § 1 paragraph 1 and 2 EGBGB and our obligations according to § 312e paragraph 1 sentence 1 BGB in conjunction with Article 246 § 3 EGBGB. To maintain the withdrawal period, the timely dispatch of the withdrawal is sufficient. The withdrawal is to be directed to: DEON GmbH & Co. KG Ella-Kay-Str. 22c 10405 Berlin E-mail: invoice@deon.de Consequences of withdrawal: In the event of an effective withdrawal, the services received on both sides must be returned and any benefits drawn (e.g. interest) must be surrendered. If you are unable to return the service received to us in whole or in part or only in a deteriorated condition, you must provide us with compensation for the value. This can lead to you having to fulfill the contractual payment obligations for the period up to the withdrawal. Obligations to reimburse payments must be fulfilled within 30 days. The period begins for you with the dispatch of your withdrawal declaration, for us with its receipt. Special note: Your right of withdrawal expires prematurely if the contract is fully fulfilled by both parties at your express request before you have exercised your right of withdrawal.
6. Support and Customer Service
Users can use the platform's contact form to send questions, instructions, and comments about Deon, the services offered, or contractual aspects.
7. Warranty
DEON provides its services "as is" without any express or implied warranty regarding functionality, availability, or suitability for a specific purpose.
DEON is unlimitedly liable for damages resulting from the violation of life, body, or health, which are based on a breach of duty by DEON, its legal representatives, or vicarious agents. For other damages, DEON is only liable in cases of intent or gross negligence. In cases of slight negligence, liability is limited to damages resulting from the violation of essential contractual obligations (cardinal obligations) and only to the foreseeable damage typical for this type of contract.
Any further liability, especially for indirect damages, consequential damages, or lost profits, is excluded to the extent permitted by law.
8. Indemnification
The user is solely responsible for their actions on the platform. The user undertakes to indemnify, defend, and hold DEON harmless from all claims by third parties, including reasonable legal costs, arising from the unlawful or non-contractual use of Deon by the user, particularly in cases of legal infringements, illegal content, or breaches of contractual obligations.
If such a claim is made, the user must immediately cease the infringing behavior at the request of DEON and actively support DEON in defending the claim.
9. Final Provisions
This document represents the entire agreement between the user and DEON regarding the use of Deon and supersedes all previous versions of this document.
DEON reserves the right to modify this agreement at any time. DEON will inform the user in a timely manner about any changes. If the user does not object to the modified agreement within six weeks after notification, the modified agreement is considered accepted.
The user agrees that DEON may communicate with them via email, post, or in-app notifications within the services, including regarding changes to these terms. These terms also apply to third-party providers, branches, affiliated companies, and subsidiaries of DEON, where applicable.
If any provision of this agreement is or becomes invalid, the remaining provisions remain unaffected. The invalid provision will be replaced by a valid provision that comes closest to the original intention in a legally permissible manner.
This agreement is governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods and the conflict of laws rules of international private law.
If the customer is a merchant, a legal person under public law, or a public-law special fund, the exclusive place of jurisdiction for all disputes arising from or in connection with this agreement is Berlin, Germany.
This agreement is written in German. In case of discrepancies between this and a translated version, the German version takes precedence.
