Welcome as a user of Vaadin’s website or as a registered community member. Your participation is valued, and we are looking forward to having you working together with us. These Vaadin Community Terms are applied to all non-commercial products, services and information offered for free on the vaadin.com website or through related tools and services.
1. GENERAL PROVISIONS AND SCOPE OF APPLICATION
The non-commercial products, services and information available through vaadin.com (“Service” or “Services”) are provided by Vaadin Ltd (“Vaadin” or “we”), with Finnish Business ID 1613563-9, located at Lemminkäisenkatu 3, 20520 Turku, Finland, or its affiliates and subcontractors.
These Vaadin Community Terms (“Terms”) control the relationship between Vaadin and you as a Service user and/or registered Vaadin community member (“you”). By using the Services, you are agreeing to these Terms as well as to Vaadin’s Privacy Policy.
Vaadin makes software available for download in the Service. Such software is always subject to separate license terms and conditions.
Vaadin also provides commercial products, services and information to its customers, including subscription fee-based products and services as well as consulting services. Separate Vaadin Commercial Terms and Conditions are applied to such commercial products and services provided against payment.
2. USING THE SERVICE
These Terms give you the right to access and use the Service for familiarizing yourself with Vaadin Framework, Vaadin Platform as well as other Vaadin products and materials (collectively “Vaadin Technologies”), exchanging information regarding Vaadin Technologies, sharing components and other contributions related to Vaadin Technologies, and downloading Vaadin Technologies and related components, and you agree not to use the Service for any other purposes. As regards the Vaadin Copilot and Vaadin Start software services, you are entitled to use them as set out in Section 8 below.
You may use the Service only as permitted by law and these Terms. You may not submit any content that violates or infringes any laws or the rights of others or is otherwise harmful. Vaadin may stop providing the Services to you if you do not comply with these Terms or we are investigating suspected misuse.
The Service and any software, materials, or information available through the Service may not be used in or for the benefit of, or exported or re-exported to (a) any EU, U.S., or other applicable sanctions authority's embargoed country or territory or (b) any individual or entity with whom dealings are prohibited or restricted under applicable trade or export control laws. You agree to comply strictly with all applicable import and export regulations and acknowledge that you are responsible for obtaining any licences required to export, re-export, transfer, or import any software or materials obtained through the Service.
3. REGISTRATION
While many of the Services are available without a registration, some Services require a registration. When you register, you will create a personal user account with a username and password. You should protect your username and password against misuse and keep them personal. You must promptly notify Vaadin about any unauthorized use.
4. GENERAL PROVISIONS ON SERVICE CONTENT
All Service users have the right to submit content in the Service. This means that the Service displays information and materials submitted both by Vaadin and Service users. All intellectual property rights related to Vaadin Technologies or other content submitted by Vaadin remain with Vaadin.
Using the Service does not give you ownership of any intellectual property in the Service or the content you access, if not expressly otherwise stated in these Terms. Before using any content from the Service, always ensure that you comply with any applicable license terms and conditions specified by the content owner or otherwise obtain the content owner’s consent to your use of the content in question.
When using the Service, you must evaluate the content in the Service carefully and bear all risks related to any content and take full responsibility of the use of any content in the Service.
Vaadin may monitor any content in the Service, and we may moderate, remove or refuse to display any content in the Service at our sole discretion. This does not mean that we necessarily review any content, so do not assume that we do.
5. YOUR SUBMISSIONS TO THE SERVICE
“Member Materials” means all materials that you as a community member provide or post, upload, input or submit for public display through the Service.
When you submit Member Materials to the Service, you are entirely responsible for that content, and you agree not to submit any unlawful content, content violating any intellectual property rights or otherwise inappropriate content. This responsibility continues even if you stop using our Services.
When you submit Member Materials to the Service, you retain ownership of any intellectual property right that you hold in such content. So that Vaadin can make the Services available to its community members, you grant Vaadin a worldwide, perpetual, irrevocable, fully paid up and unlimited license to use, store, reproduce, modify, create derivative works, communicate, publish, distribute and otherwise utilize the Member Materials. This license continues even if you stop using our Services. You represent and warrant that you have the legal right to transfer to and grant Vaadin the rights set out in this paragraph. Please always make sure you have all the necessary rights to any content you submit to the Service.
As regards software that you publish in the Service, you may specify separate license terms and conditions as set out under Section 7 below.
6. SOFTWARE AVAILABLE FOR DOWNLOAD
There is software available for download in the Service, such as Vaadin Technologies, related integration components, Vaadin add-on components, and third-party software components.
Downloading software does not give you ownership of any intellectual property in the downloaded software. You may use the downloaded software only under the license chosen by the publisher of the software.
7. PUBLISHING SOFTWARE
Any registered Service user or Vaadin can upload and publish software in the Service. If the publisher is a business, the business must be registered on the vaadin.com website with a normal user account.
Before uploading new software to the Service, you (as the publisher) agree to test the software properly, choose a license under which the software is licensed to users, list all dependencies of the software, including package name, web link and license information, and fill the requested information of the software in the Vaadin Add-On information page. As the publisher, you may set a maturity level for the software.
You, as the publisher, must select one or more licenses from the Service’s available license list for the software. The software will be made downloadable from the Service under the selected license or licenses. The available license list is based on the open-source licenses published at https://opensource.org/licenses.
You, as the publisher, may edit software published by you, publish upgrades or new versions of such software and remove such software, or its old versions, from the Service.
8. VAADIN SOFTWARE SERVICES
Vaadin provides Copilot (“Copilot”) and Vaadin Start (start.vaadin.com) as software-as-a-service tools (together, the “Software Services”).
Vaadin Start helps you create prototypes and application artifacts for your own applications. Copilot is an AI-powered assistant for Java developers, designed to work within your IDE.
General
While Vaadin makes reasonable efforts to keep the Software Services available, we do not guarantee uninterrupted or error-free operation and are not liable for any interruptions, failures, or resulting damages.
Vaadin does not provide support services for the Software Services.
All rights in the Software Services remain with Vaadin or its licensors. Vaadin grants you a limited, non-exclusive, non-transferable, and revocable right to use the Software Services in accordance with these Terms. You must not misuse the Software Services or attempt to interfere with their operation.
Vaadin may suspend or terminate your access if you do not comply with these Terms or if required to protect the Software Services or comply with applicable law. Vaadin may also close inactive accounts after 12 months, with prior notice.
You are responsible for the equipment, software, and connectivity required to use the Software Services, as well as any associated costs. Vaadin recommends using up-to-date software and browsers.
Your use of the Software Services is also subject to the general trade compliance obligations set out in Section 2. Your Input may not include material or information that requires a government licence for release or export.
Content
You may provide code, text, or other material to the Software Services (“Input”) and receive generated results (“Output”). Input and Output together are "Content”. For the avoidance of doubt, "Content" as used in this Section 8 is distinct from Member Materials as defined in Section 5.
As between you and Vaadin, and to the extent permitted by applicable law, you retain ownership of your Input. You may use Output for any lawful purpose, including commercial use. As Output is AI-generated, it may not be unique, and similar results may be generated for other users — your rights in any Output are therefore non-exclusive.
You are responsible for your Content and for your use of the Software Services. You shall not submit personal data to the Software Services. If you do, you are solely responsible for ensuring that you have a valid legal basis for such processing and that your use complies with all applicable data protection and privacy laws. Vaadin disclaims any responsibility or liability arising from the processing of personal data through the Software Services. You must ensure that your Input does not infringe third-party intellectual property rights, include third-party confidential information, or violate applicable law. If you breach any of the foregoing obligations, you will be liable to indemnify Vaadin as set out in Section 14.
YOU ACCEPT ALL OUTPUT 'AS IS', WITH NO REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, INCLUDING IN RELATION TO INTELLECTUAL PROPERTY OR OTHER RIGHTS IN OUTPUT, AND YOU USE OUTPUT AT YOUR OWN RISK WITH REGARD TO ALL SUCH RIGHTS. TO THE MAXIMUM EXTENT PERMITTED BY LAW, VAADIN DISCLAIMS ALL LIABILITY ARISING FROM YOUR USE OF ANY OUTPUT. Output may not always be accurate, complete, or reliable. You are responsible for reviewing and validating all Output before use, including by using human review. You should not rely on Output as a substitute for professional advice or independent judgement.
Vaadin treats your Content as confidential and uses it only as necessary to provide, maintain, and improve the Software Services, comply with legal obligations, and enforce these Terms. Vaadin does not use your Content to train the artificial intelligence models used in the Software Services and does not publicize or distribute your Content. The preceding sentence does not, however, restrict Vaadin's rights to information from independent sources that also appears in Output.
If you choose to provide feedback (such as ratings), you grant Vaadin a perpetual, irrevocable, and royalty-free right to use feedback for any purpose, including for statistical purposes and for developing the Software Services. Feedback is retained only for a limited period. In case you disable feedback, Vaadin does not access your Content, which may limit the ability of the Software Services to address your specific use case.
Vaadin may store temporary backup copies of Content to operate the Software Services but is not responsible for any loss of data. You are responsible for maintaining your own copies of Content.
Copilot
Copilot is powered by generative AI technologies provided by third parties, currently including OpenAI, LLC, Mistral AI SAS, and Anthropic PBC (“AI Providers”).
Given the probabilistic nature of machine learning and generative AI, Output — including any software code — may not always be accurate or error-free. You are responsible for reviewing and testing any code before use.
Vaadin provides Copilot in accordance with the applicable terms and conditions and use policies of the AI Providers, available at https://openai.com/policies/, https://legal.mistral.ai/terms, and https://www.anthropic.com/legal/ respectively.
Vaadin does not control the AI Providers' services and is not responsible for the availability, accuracy, or performance of AI Provider services. To enable Copilot, your Content may be shared with and processed by these AI Providers, including for generating responses, content moderation, and other purposes consistent with these Terms.
Your use of Copilot must comply with applicable law and the terms and policies of the AI Providers. You may not use Copilot for any unlawful, harmful, or abusive purposes, or in any way that violates those policies. Your use of Copilot in violation of these Terms or applicable AI Provider policies gives rise to the indemnity obligations set out in Section 14.
Vaadin Start
Vaadin Start processes the configuration and inputs you provide in order to generate application prototypes and artefacts. Vaadin treats such data as confidential in accordance with the Content provisions above and uses it only as necessary to provide and maintain the Vaadin Start service. Vaadin does not use your Vaadin Start inputs to train any AI or machine learning models.
9. USE OF VAADIN NAME AND TRADEMARKS
When naming your software, you may, but do not have to, indicate your software’s connection to Vaadin Technologies by naming it as “XXX for Vaadin” (you may not, however, name your component as “Vaadin XXX”). Also, when naming packages for APIs, you are allowed and encouraged to use the org.vaadin.* prefix, if your software is distributed under an open source license. The package prefix com.vaadin.* is reserved for Vaadin only.
“Vaadin” and “}>” are registered trademarks of Vaadin and may not be used without permission from us.
10. COPYRIGHT PROTECTION FOR VAADIN
Please notify Vaadin if you think that somebody is violating our copyrights, by email to privacy@vaadin.com or by filling out our online contact form.
11. FREE EXCHANGE OF INFORMATION
Except as set out below, Vaadin does not treat content that you submit to or receive from the non-commercial Service as confidential.
For clarity, information exchanged as part of commercial services is subject to confidentiality provisions of the Vaadin Commercial Terms and Conditions. Furthermore, data submitted to or created in the Software Services, including Copilot and Vaadin Start, is handled in accordance with Section 8 above.
12. DISCLAIMERS AND WARRANTIES
YOU EXPRESSLY UNDERSTAND AND AGREE THAT YOUR USE OF THE SERVICE IS AT YOUR SOLE RISK AND THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS. TO THE FULLEST EXTENT PERMITTED BY LAW, AND WITHOUT LIMITING THE DISCLAIMERS SET OUT IN SECTION 8 ABOVE, VAADIN AND ITS AFFILIATES, PERSONNEL AND PARTNERS EXPRESSLY DISCLAIM ANY AND ALL WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. VAADIN AND ITS AFFILIATES, PERSONNEL AND PARTNERS MAKE NO WARRANTY THAT (I) THE SERVICE WILL MEET YOUR REQUIREMENTS; (II) YOUR USE OF THE SERVICE WILL BE TIMELY, UNINTERRUPTED, SECURE OR ERROR-FREE; (III) ANY INFORMATION OBTAINED BY YOU AS A RESULT OF THE SERVICE WILL BE ACCURATE OR RELIABLE; AND (IV) ANY DEFECTS OR ERRORS IN THE SOFTWARE PROVIDED TO YOU AS PART OF THE SERVICE WILL BE CORRECTED. ANY MATERIAL DOWNLOADED OR OTHERWISE OBTAINED THROUGH THE USE OF THE SERVICE IS ACCESSED AT YOUR OWN DISCRETION AND RISK, AND YOU WILL BE SOLELY RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE OR LOSS OF DATA THAT RESULTS FROM THE DOWNLOAD OF ANY SUCH MATERIAL. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED BY YOU FROM VAADIN OR THROUGH OR FROM THE SERVICE SHALL CREATE ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.
13. LIMITATION OF LIABILITY
YOU EXPRESSLY UNDERSTAND AND AGREE THAT VAADIN AND ITS AFFILIATES, PERSONNEL AND PARTNERS SHALL NOT BE LIABLE TO YOU FOR ANY DIRECT, INDIRECT, SPECIAL, INCIDENTAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT LIMITED TO BUSINESS INTERRUPTION, LOSS OF USE, LOSS OF DATA, LOSS OF PROFITS, LOSS OF REVENUES, LOSS OF BUSINESS OPPORTUNITIES AND LOSS OF GOODWILL, OR DAMAGES CAUSED TO THIRD PARTIES OR BY THE PURCHASE OF REPLACEMENT PRODUCTS OR SERVICES, EVEN IF THEY HAVE BEEN ADVISED OF OR SHOULD HAVE FORESEEN SUCH DAMAGES. VAADIN'S LIABILITY, IF ANY, IS LIMITED TO THE LESSER OF (A) THE AMOUNTS WHICH YOU PAID TO VAADIN FOR THE SERVICE; OR (B) THE MINIMUM AMOUNT ALLOWED UNDER APPLICABLE MANDATORY LAW. THIS LIMITATION OF LIABILITY SHALL APPLY REGARDLESS OF THE CAUSE OF ACTION OR LEGAL THEORY PLED OR ASSERTED, INCLUDING NEGLIGENCE, BREACH OF CONTRACT AND WARRANTY.
14. INDEMNITIES
You agree to defend, indemnify and hold harmless Vaadin and its affiliates and licensors from and against any and all third party claims and all liabilities, assessments, losses, costs or damages resulting from or arising out of (a) any content you submit, post, transmit, or otherwise make available through the Service, including any Input submitted to the Software Services; (b) your use of the Service, including your use of Copilot; (c) any violation by you of these Terms, including any breach of the obligations set out in Section 8; or (d) your violation of any rights of another; or (e) your violation of the applicable terms and policies of the AI Providers. The foregoing is in addition to, and without limiting, any indemnification obligations set out in Section 8 above. This obligation shall survive the termination or expiration of these Terms and/or your use of the Service.
15. CHANGES TO THESE TERMS
Vaadin may change these Terms at any time. For material changes, Vaadin will provide at least thirty (30) days' prior notice on the vaadin.com website and by email to registered users. For non-material changes — such as clarifications, corrections, or updates to reflect new features — changes take effect upon posting, and we recommend that you review the Terms regularly.
If you do not agree to the new Terms for the Service, you should discontinue your use of the Service. None of the changes will apply retroactively and the changes will become effective on the announced date.
16. MODIFYING THE SERVICE
Vaadin may change the Service by adding, modifying or removing any features or functionalities. Vaadin may also stop providing parts of, or the whole of, the Service. We may also create new operating guidelines or limitations to the Service at any time.

You may not assign or transfer your rights or obligations under these Terms to any third party without Vaadin's prior written consent. Vaadin may assign these Terms and the rights and obligations contained herein to a company belonging to the same group of companies as Vaadin, or to a third party to which the business of Vaadin is transferred.
