Terms of Use

Aster terms of use for Aster-technologies.com

General Terms of Use

Scope

These Terms of Use, along with any specific terms when applicable, govern the interactions of any visitor on this Website and any functionally related websites (“User”).

1.1. Any use of this website and any functionally related websites ("Aster Website") operated and administered by the Aster entity specified on the Website imprint ("Aster"), is subject to these Terms of Use. These Terms of Use may be amended, modified or replaced by other terms and conditions, e.g. for the purchase of products and services.

1.2. In the case of web offers aimed at companies or public enterprises, such companies or enterprises are represented by the User and must assume that the User has appropriate knowledge and acts accordingly.

Services

2.1. The Aster Website contains specific information and software, as well as - as the case may be - related documentation, for viewing or downloading. The Aster Website may also serve as or provide access to online platforms or marketplaces for the promotion and transaction of offerings from Aster and/or third parties.

2.2. Aster may stop the operation of the Aster Website in full or in part at any time. Due to the nature of the internet and computer systems, Aster cannot accept any liability for uninterrupted availability of the Aster Website.

Registration, Password

3.1. Some pages of the Aster Website may be password protected. In the interest of safety and security of business transactions, only registered Users may access said pages. Aster reserves the right to deny registration to any User. Aster particularly reserves the right to make certain sites, which were previously freely accessible, subject to registration. Aster is entitled, at any time and without obligation to give reasons, to deny the User the right to access the password-protected area by blocking its User Data (as defined below), in particular if the User

uses false data for the purpose of registration;
violates these Terms of Use or neglects its duty of care with regard to User Data;
violates any applicable laws in the access to or use of the Aster Website; or
did not use the Aster Website for a long period of time.

3.2. For registration the User shall give accurate information and, where such information changes over time, update such information (to the extent possible: online) without undue delay. The User shall ensure that its e-mail address, as supplied to Aster, is current at all times and an address at which only the User can be contacted. For the avoidance of doubt, the e-mail address must be linked to a specific person (e.g. - john.smith@company.com). Generic or role-based e-mail addresses linked to groups or functions (e.g. - info@company.com) may not be used.

3.3. Upon registration the User will be provided with an access code, comprising a User ID and a password ("User Data"). On first access the User shall promptly change the password received from Aster into a password known only to the User. The User Data allows the User to view or change its data or, as applicable, to withdraw its consent to data processing.

3.4. The User shall ensure that User Data is not accessible by third parties and is liable for all transactions and other activities carried out under its User Data. At the end of each online session, the User shall log-off from the password protected websites. If and to the extent the User becomes aware that third parties are misusing its User Data the User shall notify Aster thereof without undue delay in writing, or, as the case may be, by e-mail.

3.5. After receipt of the notice under paragraph 3.4, Aster will deny access to the password-protected area under such User Data. Access by the User will only be possible again upon the User's application to Aster or upon new registration.

Right of use to Information, Software and Documentation

4.1. Separately agreed to license terms, for example software downloads or services offered over the Website, shall prevail over these Terms of Use. 4.2 – 4-5 are only applicable in case no specific license terms have been agreed upon.

4.2. The use of any information, software and documentation made available on or via the Aster Website is subject to these Terms of Use or, in case of updating information, software or documentation, subject to the applicable license terms provided by or previously agreed with Aster.

4.2. Aster grants User a non-exclusive and non-transferable license, which may not be sublicensed, to use solely for its own business purposes the information, software and documentation made available to the User on or via the Aster Website to the extent agreed, or in the event of no such agreement to the extent of the purpose intended by Aster in making same available.

4.3. If not otherwise specifically agreed, software made available to User will be provided in object code. There shall be no right for the source code to be made available. This shall not apply to source code related to open source software, which license conditions take priority over these Terms of Use in the case of transfer of open source software and which conditions require the making available of the source code. In such case Aster shall make the source code available in return for the payment of costs.

4.4. Information, software and documentation may not be distributed by the User to any third party at any time nor may it be rented or in any other way made available. Unless such is allowed by mandatory law, the User shall not modify the software or documentation nor shall it disassemble, reverse engineer or decompile the software or separate any part thereof. The User may make one backup copy of the software where necessary to secure further use in accordance with these Terms of Use.

4.5. The information, software and documentation are protected by copyright laws as well as international copyright treaties as well as other laws and conventions related to intellectual property. The User shall observe such laws and in particular shall not modify, conceal or remove any alphanumeric code, marks or copyright notices neither from the information nor from the software or documentation, or any copies thereof.

Intellectual Property

5.1. Notwithstanding the particular provisions in § 4 of these Terms of Use, information, brand names and other contents of the Aster Website may not be changed, copied, reproduced, sold, rented, used, supplemented or otherwise used in any other way without the prior written permission of Aster.

5.2. Except for the rights of use and other rights expressly granted herein, no other rights are granted to the User nor shall any obligation be implied requiring the grant of further rights. Any and all patent rights and licenses are expressly excluded.

5.3. Aster may, without charge, use any data, ideas or proposals stored by a User on the Aster Websites for the development, improvement and sale of all its offerings.

Aster may monitor the User's compliance with and analyze any violation of these Terms of Use.

To ensure compliance with these Terms of Use, Aster may take action against any content or resource that violates these Terms of Use or any other agreement Aster has with the User for use of the Aster Websites or where Aster is permitted or required by law or a competent authority. This may include removing, restricting, limiting, or disabling access to content or requesting the User to modify the content. Aster may also suspend or terminate the User's account if the User repeatedly or seriously infringes third-party rights, violates any law or regulation, these Terms of Use, or where Aster is permitted or required to do so by law or a competent authority.

Information on how to report any violation of these Terms of Use, including any content the User believes to be illegal, can be found on the Digital Services Act information page on the Aster Website, available under https://www.siemens.com/global/en/company/about/compliance/eu-digital-services-act.html and on the DMCA information page, available under https://www.siemens.com/en-us/company/customer-partner-terms/sw-terms/dmca. In addition, the User may report any suspected or actual violations of law or company policy at Aster or in Aster' supply chain via the protected reporting channels available under https://www.siemens.com/global/en/company/about/compliance/reporting-channels.html.

When Aster receives notice of any violation of these Terms of Use, Aster will manually review the reported activity. Aster may suspend the handling of notices and complaints from a User for a reasonable period of time and after having issued a warning if the User frequently submits notices or complaints that are manifestly unfounded. When making such decisions, Aster will assess, on a case-by-case basis and in a timely, diligent, and objective manner, the potential misuse and will consider all relevant facts and circumstances apparent from the information available to Aster

Aster may report any activity that Aster suspects violates any law or regulation or forward any report as required by law to a competent authority or other appropriate third parties. Aster may also share the User's content if a party claims that the User's use of the Aster Website or the User's content violates third party's rights or any law or regulation.

6.5 Indemnification

The User shall indemnify and hold harmless Aster, its affiliates, subcontractors, and their representatives against any third-party claims, damages, and necessary costs (including reasonable attorney's fees) and compensate Aster for all losses and expenses arising from the User’s intentional or negligent violation of these Terms of Use, applicable laws, or the rights of third parties in connection with the use of any Aster Website or online platform, or the User’s content uploaded thereto. This indemnification obligation does not apply to users who are consumers, i.e., natural persons acting for purposes outside their trade, business, or profession.

Hyperlinks

The Aster Website may contain hyperlinks to the web pages of third parties. Aster shall have no liability for the contents of such web pages and does not make representations about or endorse such web pages or their contents as its own, as Aster does not control the information on such web pages and is not responsible for the content and information given thereon. The use of such web pages shall be at the sole risk of the User.

Liability of defects for title or quality

8.1. Insofar as any information, software or documentation is made available at no cost, any liability for defects as to quality or title of the information, software and documentation especially in relation to the correctness or absence of defects or the absence of claims or third party rights or in relation to completeness and/or fitness for purpose are excluded except for cases involving willful misconduct or fraud.

8.2. The information on the Aster Website may contain specifications or general descriptions related to the technical possibilities of individual products which may not be available in certain cases (e.g. due to product changes). The required performance of the product shall therefore be mutually agreed in each case at the time of purchase.

Other Liability, Viruses

9.1. The liability of Aster for defects in relation to quality and title shall be determined in accordance with the provisions of § 8 of these Terms of Use. Any further liability of Aster is excluded unless required by law, e.g. under the Act on Product Liability or in cases of willful misconduct, gross negligence, personal injury or death, failure to meet guaranteed characteristics, fraudulent concealment of a defect or in case of breach of fundamental contractual obligations. The damages in case of breach of fundamental contractual obligations is limited to the contract-typical, foreseeable damage if there is no willful misconduct or gross negligence.

9.2. Although Aster makes every endeavor to keep the Aster Website free from viruses, Aster cannot make any guarantee that it is virus-free. The User shall, for its own protection, take the necessary steps to ensure appropriate security measures and shall utilize a virus scanner before downloading any information, software or documentation.

9.3. §§ 9.1 and 9.2 do not intend nor imply any changes to the burden of proof to the User's disadvantage.

9.4 Where User is located in the United States of America, the following deviating warranty and liability provision applies and, notwithstanding any other provision of these Terms of Use, supersedes all other provisions relating to liability and warranty for such User:

Aster make no representations or warranties regarding the accuracy or completeness of the Aster Website’s content. Except as specifically provided in these Terms of Use, the Aster Website is provided to User “as is”. Aster make no other representation or warranty, either express or implied. Aster do not warrant the accuracy, completeness, performance, currency, merchantability, or fitness for a particular purpose of the Aster Website or the method of delivering that information to User. Aster disclaims all responsibility for cases involving any loss or claim of any kind resulting from, arising out of, or any way related to (a) errors in or omissions in the Aster Website, including technical inaccuracies and typographical errors, (b) any third party websites or content therein directly or indirectly accessed through links in any of the Aster Website’s content, (c) the unavailability of the Aster Website, (d) any use of the Aster Website, (e) any use of any equipment or software in connection with the Aster Website, or (f) any reliance on the information contained in the Aster Website, even if advised of the possibility of such damages. In no event shall Aster, or its or their respective officers, directors, employees, shareholders, agents, or representatives, be liable to User or any other person for any special, indirect, incidental, exemplary, punitive, or consequential damages or loss of goodwill in any way arising from or relating to the use of or inability to use the Aster Website, even if Aster has been notified of the possibility of such damages. In no event may User bring any claim or cause of action against Aster more than one (1) year after such claim or cause of action arises.

Compliance with Export Control Regulations

10.1. If the User transfers information, software and documentation provided by Aster to a third party, the User shall comply with all applicable sanctions, embargoes and (re-) export control laws and regulations, and, in any event, with those of the European Union, the United States of America and the Federal Republic of Germany (collectively “Export Regulations”). The User shall not access or use the Aster Website from any location prohibited by or subject to comprehensive sanctions under the Export Regulations (e.g., Cuba, Iran, North Korea, Syria, and the non-government controlled areas of Ukraine) or grant access to any individual or entity on a relevant sanctioned party list.

10.2. Prior to any such transfer to a third party the User shall in particular check and certify by appropriate measures that

The User’s transfer, use, or distribution of such information, software and documentation, the brokering of contracts or the provision of other economic resources in connection with them will not be in violation of any Export Regulations, also taking into account any prohibitions to circumvent these (e.g., by undue diversion);
Such information, software and documentation provided by Aster are not intended or provided for prohibited or unauthorized non-civilian purposes (e.g., armaments, nuclear technology, weapons, or any other usage in the field of defense and military);
The User has screened all direct and indirect parties involved in the receipt, use, transfer, or distribution of the Goods and Services against all applicable restricted party lists of the Export Regulations concerning trading with entities, persons and organizations listed therein.

10.3. If required to enable authorities or Aster to conduct export control checks, the User, upon request by Aster, shall promptly provide Aster with all information pertaining to the particular end-user, the particular destination and the particular intended use of information, software and documentation provided by Aster, as well as any export control restrictions existing.

10.4. Aster shall not be obligated to fulfill these Terms of Use if such fulfillment is prevented by any impediments arising out of national or international foreign trade or customs requirements or any embargoes or other sanctions.

Supplementary Agreements, Place of Jurisdiction, Applicable Law

11.1. Aster may revise, add, or remove parts of these Terms of Use from time to time. Continued use of the Aster Website after such changes constitutes acceptance of the new Terms of Use.

In this case and where User seeks to do business with Aster, the User should contact the Aster representative for the particular country for country specific business.

11.4. These Terms of Use and all disputes arising from or in connection with them shall be governed by:

the laws of Germany (excluding its conflict of laws principles), or

Online Platforms and Marketplace Terms

These Online Platforms and Marketplace Terms amend the General Terms of Use (see A. General) with respect to the User's access to, or purchase of certain products or services on, Aster online platforms and marketplaces offered via the Aster Website:

B2B Environment

Any online platform or marketplace on the Aster Website is intended for business-to-business (B2B) use only and not for consumers. By registering and accessing the platform or marketplace, the User confirms acting for business, commercial, or professional purposes and not in the capacity of a consumer. Aster may require the User to provide suitable proof of its status as an entrepreneur or business user (e.g., a VAT ID number). The data required for verification must be provided by the User in a complete and truthful manner.

Types of Offerings and Role of Aster

The platform may list products, software, or services (“Offerings”). Offerings may be sold by Aster (“Aster Offerings”) or by external third-party sellers (“Third-Party Offerings”). For all Third-Party Offerings, Aster acts only as a facilitator to the transaction and is not the seller of record or a party to the agreement between the User and the third-party seller.

Governing Terms for Offerings

3.1. Use of a Aster Offering is governed by the applicable Aster agreement documents presented during the order process (“Aster Terms”). In the event of a conflict between these Terms of Use and the Aster Terms, the Aster Terms will control as to each party’s rights and responsibilities related to the Aster Offering itself, while these Terms of Use will control as to the use of the online platform or marketplace.

3.2. Use of a Third-Party Offering is governed by the terms and conditions provided by the third-party seller ("Third-Party Terms”), not the Aster Terms. By ordering a Third-Party Offering, the User enters into a direct agreement with the third-party seller. Aster is not a party to, and has no responsibility or liability under, any Third-Party Terms. The User acknowledges that:

Aster is not responsible for compliance with the Third-Party Terms;
Aster does not guarantee any Third-Party Terms are adequate for the User's needs;
Aster is under no obligation to test, validate, or otherwise review the Third-Party Offering;
Aster does not assume any obligation or responsibility with regard to the use of the Third-Party Offering, its support or any other related services or products, whether or not they are designated by Aster as “certified” or otherwise; and
Aster is not responsible for any dispute between the User and the third-party seller, but Aster may elect to assist in resolving any dispute. If Aster elects to assist, the User agrees to co-operate with Aster to resolve the dispute.

3.3. The Aster Terms or Third-Party Terms applicable to an ordered Offering are referenced via links during the order process. Aster recommends that the User saves or prints the applicable terms; Aster does not save these terms for the User.

Orders and Conclusion of Contract

Unless expressly stated otherwise, the following process shall apply:

The presentation of Offerings on a platform or marketplace does not constitute a binding offer. Only the User's order constitutes a binding offer to the relevant seller to purchase the Offering. Prior to placing a binding order, the User will be presented with a summary of the order and will have the opportunity to identify and correct any input errors using the technical means provided. The User may cancel the ordering process at any time before the order becomes binding. When the User places an order, an email may be sent confirming the receipt of the order. This order receipt confirmation does not constitute an acceptance of the User's offer. A contract is only concluded if the order is accepted by the seller, which is typically confirmed with another email detailing the particulars of the order or by the provisioning of the Offering.

Maintenance and Support

Maintenance and support of Aster Offerings will be provided pursuant to the applicable Aster Terms. Any maintenance and support of Third-Party Offerings will be provided by the applicable third-party seller and only to the extent described in the applicable Third-Party Terms. Aster is not responsible for any maintenance and support for Third-Party Offerings.

Payments and Invoicing

Where Offerings are available for purchase, the User must pay the applicable fees. The platform may offer various payment methods. For payment by credit card, fees are typically due in advance at the time of purchase, unless stated otherwise. For purchase on an existing account with Aster, the payment terms contained in the separate agreement between the User and Aster shall apply. The User consents to receiving electronic invoices from the respective seller (whether Aster or a third-party) for all transactions conducted on the platform.

User's Representations and Authorizations

By entering payment information, the User represents that it is an authorized user of the payment method and that the associated information is accurate. The User authorizes Aster or its payment service provider to:

charge the full amount due for the Offerings to the selected payment method;
charge the amount due for any automatic renewals of a subscription to which the User has agreed; and
return to the payment method any funds due to the User resulting from a purchase.

Failed Payments

Aster is not liable for any payments that are not completed due to insufficient funds or credit limit, incorrect information provided by the User, or other circumstances beyond Aster’s reasonable control. To the extent any amounts owed cannot be collected from the payment method provided, Aster has the right to charge the amount of any such transaction to the User's account (if any), to otherwise collect the amounts due from the User, or to terminate the related order.

Request for Quote Option

Certain Offerings may permit the option to request a quote from the applicable seller. Where the User selects this option, all resulting transactions will be concluded outside the platform in accordance with the applicable seller’s terms provided to the User along with the quote.

Ownership

Except for the rights of use expressly granted to the User in these Terms of Use, all right, title and interest (including intellectual property rights) in the online platform or marketplace are reserved by Aster. All right, title and interest (including intellectual property rights) in the Offerings are reserved and retained by their respective seller (whether Aster or a third-party) and its licensors.

AI Terms of Use

These AI Terms of Use amend the Aster Terms of Use (see A. General) with respect to any AI powered conversational experiences in services provided by Aster on the Aster website, as well as any other AI powered generative experiences on or resulting from services provided by Aster on the Aster website (collectively “AI Services”).

Nature and Limitations of Content

AI Services generate content for general informational use only. While this may encompass information related to Aster, its products, and solutions, all such content is subject to inherent AI limitations and based on available training data. It is inherently subject to inaccuracies, incompleteness, or becoming outdated. This content does not constitute legal, medical, or professional advice, nor does it include binding offers or accurate pricing information. Specifically, AI Services are not intended to provide financial information, including forward-looking statements or capital market-related information, and the User of AI Services agrees not to rely on its responses for such purposes. The User should independently verify the accuracy and appropriateness of any content before relying on or utilizing such content for any purpose. Aster disclaims all liability for any inaccuracies, omissions, or reliance on such content.

AI Services Use Restrictions

The User shall not:

use AI Services beyond the scope of access granted;
permit any other users to access or use AI Services to develop, train, or improve any other AI, including a competing or similar product or service;
use web scraping, web harvesting, web data extraction, or any other method to extract data from AI Services;
use AI Services to create content or use content in a manner that the User knows or should know infringes, misappropriates, or otherwise violates any intellectual property rights or other rights of any person, or that violates any applicable law, regulation, or rule.

High-Risk Use

AI Services are not intended for use in High-Risk contexts. Aster will not be liable for any claims, damages, losses, costs, or liabilities arising from the use of our AI Services in High-Risk contexts, and the User will indemnify and hold Aster harmless against any such claims.

"High-Risk contexts" means situations where AI Services are used to inform or make decisions that require enhanced safety measures or risk management features, such as fail-safe or fault-tolerant systems. This includes contexts where failure or malfunction may reasonably be expected to result in death, personal injury, property or environmental damage, or significant impacts on fundamental rights. High-Risk contexts include, but are not limited to, critical infrastructure, healthcare, transportation safety, biometric identification, education and employment decisions, law enforcement, migration, justice, and democratic processes, as well as any other high-risk AI practices defined or prohibited by applicable laws and regulations.

Liability

Sections 8 (Liability of defects for title or quality) and 9 (Other Liability, Viruses) of Aster' general website Terms of Use (see A. General) apply mutatis mutandis to AI Services and its generated content. For these applications, references to "information," "software," "documentation," "goods," "services," "facilities," or "equipment" also include AI Services and its outputs.

Use Rights of Aster

Aster may collect, store, and analyze conversational experiences with AI Services (input and generated content) to train and improve its products or services and enhance the overall user experience. This use includes, but is not limited to, identifying patterns, correcting inaccuracies, and enhancing response quality.

Use Rights for the User

Content generated by code generation features of AI Services may be subject to third party licenses, including, without limitation, open source licenses (“Third Party Licenses”) or Aster proprietary licenses. Subject to the User’s compliance with these AI Terms of Use and to the extent such granting of use rights (i) is permitted by applicable law and (ii) does not conflict with rights of others (including Third Party Licenses) or Aster proprietary licenses, as between the parties, Aster grants the User a non-exclusive, worldwide, royalty-free right to use the content generated by code generation features of our AI Services. Except for the use rights expressly granted herein, User shall not acquire any title, interest or right in any pre-existing, underlying or independently developed data, information, or intellectual property of Aster. In case AI Services are embedded in the Aster Xcelerator Developer Portal, the code generation features of AI Services are intended solely for content associated with and based on the Aster Xcelerator Developer Portal. The User is expressly prohibited from using these features for content unrelated to the Aster Xcelerator Developer Portal.

Changes to these AI Terms of Use

Aster may modify these terms at any time.
