The User may use the Materials solely for lawful internal use purposes. The scope of the license is as follows:

1. Territory: This license is worldwide; provided that the User shall nevertheless comply with the applicable laws and regulations of its location, the place of use and the place where the Materials are provided, and shall be bound by each of the restrictions set forth in Articles 4 and 5.

2. Subsidiaries and Affiliates: Where the User is a juridical person or other organization, it may permit its subsidiaries in which it directly or indirectly holds more than fifty percent (50%) of the voting shares, and other affiliates controlled by the same ultimate parent company, to use the Materials within the scope of the same lawful internal use purposes. The acts of such subsidiaries or affiliates shall be deemed the acts of the User itself, and the User shall be liable therefor as for its own acts; upon loss of such control or affiliate relationship, such right of use shall terminate simultaneously.

3. Nature of the License: The Materials are “licensed” and not “sold”, and are provided free of charge. This license is non-exclusive, non-transferable, non-sublicensable and revocable. Except as expressly granted under these Terms, Delta reserves all rights in and to the Materials, and no right not expressly granted shall be presumed to have been granted by implication, estoppel or otherwise.

4. Version Differences: Delta may separately announce on its official website license conditions of differing scope of application for different versions of the Materials or different categories of Users, and such announcements shall constitute part of these Terms.

1. The Materials may contain Open Source Components. The use, reproduction, modification and distribution of each Open Source Component shall be governed by its respective open source license terms and copyright notices. The User shall comply with the license terms and copyright notices applicable to each Open Source Component.

2. The scope of license set forth in Article 2 and the use restrictions set forth in Articles 4 and 5 apply only to the Delta Proprietary Portions and do not apply to Open Source Components; where any provision of these Terms conflicts with the license terms of an Open Source Component, such open source license terms shall prevail to the extent of the conflict.

3. The Materials may contain third-party software or non-open-source components, or may interface with third-party services. The User shall itself read and confirm the contents of all such third-party terms; Delta shall not be responsible for the functionality, quality, availability or legality of any third-party software or service, nor shall these Terms expand or alter any right granted by any third party.

4. With respect to the use, reproduction, modification and distribution of such third-party software or services, the User shall, in addition to these Terms, comply with the applicable third party’s license terms, end user license agreement or terms of service; where such terms conflict with these Terms, the third party’s terms shall prevail with respect to such third-party software to the extent of the conflict.

5. The User shall bear all liability arising from its breach of the license terms of any Open Source Component or of any third party, and shall hold Delta harmless from any and all claims and damages suffered as a result thereof.

Except as expressly permitted under these Terms, as provided in Article 3, Paragraph 2, or where such restriction is expressly prohibited by applicable law, the User shall not itself, and shall not permit, assist or induce any third party to, engage in any of the following acts (this Article applies only to the Delta Proprietary Portions; Open Source Components are governed by Article 3):

1. reverse engineer, decompile, disassemble, decrypt or crack the Materials, or otherwise seek to discover their source code, algorithms or trade secrets;

2. circumvent, defeat or disable any technical measure implemented by Delta to control access, verify licensing, ensure integrity or prevent abuse, or develop or distribute any alternative means for any of the foregoing purposes;

3. remove, alter, obscure or render illegible or difficult to identify any copyright notice, trademark, license marking, watermark, source attribution or other proprietary notice contained in the Materials;

4. sell, rent, lend, sublicense, pledge or otherwise dispose of the Materials; or provide the benefit of the Materials or of their functionality to any third party for consideration, whether through timesharing, service bureau, hosting, managed operation or any other arrangement;

5. publicly disclose the results of any performance benchmarking, stress testing, security testing or competitive analysis of the Materials without Delta’s prior written consent;

6. use the Materials for the purpose of developing, training or improving any product or service that is substantially competitive with the Materials, or for any other purpose that is manifestly unfair to Delta commercially;

7. disassemble, repackage, rename or redistribute the Materials for the purpose of circumventing the prohibited uses set forth in Article 5; or

8. modify, adapt or integrate, modify, adapt, translate, compile or refactor the Materials.

The User shall not export, re-export, transfer or otherwise make the Materials or any derivative works thereof available for any of the following uses, nor shall the User itself engage in, or permit, assist or induce any third party to engage in, any of the following:

the research and development, manufacture, testing or use of weapons or for military purposes;

The Materials shall not be used for the benefit of Russia, Belarus, Iran, North Korea, Syria, Cuba or any other country or region designated as comprehensively embargoed under applicable international law;

any other use prohibited under applicable law.

Where there is reasonable ground to believe that a third party’s use will violate the foregoing restrictions, the User shall not provide the Materials to such third party.

1. The User represents and warrants that: (1) it has full legal capacity and the authority to enter into these Terms; (2) it is not a restricted party listed on any applicable export control or economic sanctions list, nor is it controlled by any party so listed; and (3) its use of the Materials complies with these Terms and all applicable laws.

2. The User shall be liable for the acts of its employees, contractors and agents, and of any third party to which it provides the Materials, as for its own acts.

1. Delta may at any time, at its sole discretion, modify the Materials, or remove or disable any part of their functions or components.

2. For the purposes of maintaining information security, remedying critical vulnerabilities or complying with legal requirements, Delta may apply mandatory updates to the Materials, and may make acceptance of such updates a condition of continued use of the Materials.

3. These Terms do not of themselves confer upon the User any right to obtain updates, upgrades or new versions at any future time.

1. If the User discovers a security vulnerability in the Materials, the User shall report the same to Delta through the reporting channels announced by Delta, and shall not publicly disclose the details of such vulnerability or any exploitable attack code until Delta has completed remediation, or during such other reasonable period as the parties may agree.

2. In order to avoid material harm to the User, Delta may, to the extent necessary, take measures including issuing security advisories and suspending specific functions of the Materials or related services.

1. Where the User is a juridical person or other organization, Delta may, to the extent reasonably necessary, request the User to provide information relating to its use of the Materials (for example, number of deployments, versions and manner of use) in order to verify its compliance with these Terms.

2. Failure by the User to provide the requested information within the reasonable period designated by Delta shall constitute a material breach of these Terms.

3. Where Delta discovers any non-compliance, Delta may require the User to remedy the same immediately, to obtain and pay for the corresponding license, and to compensate Delta for the damages, losses and expenses arising therefrom; pending full remediation, Delta may suspend or terminate the User’s access to the Materials and related services without prior notice.

1. The Materials may, in the course of their operation, collect information relating to usage, installation environment and error events. The purposes, categories, period, territory, recipients and manner of Delta’s collection, processing and use of such information shall be governed by the privacy policy published by Delta.

2. Where the User uses the Materials to collect, process or use personal data, the User is an independent collector or processor of such personal data and shall itself confirm and comply with the requirements of the Personal Data Protection Act and other applicable laws. The rights granted by Delta to the User under these Terms do not mean that the User has obtained a lawful basis for processing any personal data.

All copyrights, patents, trademarks, trade secrets and other intellectual property rights in the Materials (excluding Open Source Components) are owned by Delta or its licensors. The User’s acquisition, possession or use of the Materials shall not effect any transfer of intellectual property rights.

Delta undertakes no express or implied obligation of confidentiality with respect to the Feedback; 3. Delta may, at its sole discretion, use, modify or disclose such Feedback for any purpose and in any territory; and 4. Delta thereby incurs no obligation to the User and no liability for any compensation or remuneration.

1. Except for fair use, the User shall not use the Delta Marks without Delta’s prior written consent.

2. The User shall not apply for registration of any trademark or other right in any country or region using the Delta Marks alone or in combination with other words, nor shall the User expressly or impliedly represent to others that it enjoys any right to display, use or dispose of the Delta Marks.

3. The User shall not use any name, mark or representation sufficient to cause others to mistakenly believe that a cooperative, endorsement, sponsorship or other relationship exists between the User and Delta.

The User shall be under an obligation of confidentiality with respect to Delta’s confidential information learned by reason of the Materials (including without limitation trade secrets, non-public technical information and source code, in whatever form presented), shall not disclose the same to any third party without Delta’s prior written consent, and shall take reasonable measures to prevent any third party from becoming aware thereof.

1. The Materials are provided “AS IS”, with all faults.

2. To the maximum extent permitted by applicable law, Delta and its licensors make no warranty or guarantee of any kind with respect to the Materials, whether express, implied or statutory, including without limitation any warranty of merchantability, fitness for a particular purpose, title or non-infringement, or any warranty arising from course of dealing, course of performance or usage of trade.

3. Delta does not warrant that the Materials are free from error, viruses or other defects, that their operation will be uninterrupted, that they will meet the User’s particular requirements, or that any error will be corrected; nor does Delta give any warranty as to the accuracy, completeness or reliability of the results they produce.

1. The User shall itself adopt appropriate data security, data backup and disaster recovery measures.

2. To the maximum extent permitted by applicable law, Delta and its licensors shall not be liable for any indirect, incidental, special, punitive or consequential damages arising out of these Terms, the Materials or the inability to use the Materials (including without limitation loss of revenue, loss of profit, loss of anticipated savings, loss of business, loss of opportunity, loss of goodwill or reputation, or loss of data or information), regardless of whether the claim is founded in contract, tort (including negligence), strict liability or otherwise, and regardless of whether Delta has been advised of the possibility of such damages.

3. To the maximum extent permitted by applicable law, Delta shall bear no liability whatsoever under these Terms.

Where Delta suffers any claim, demand, action or administrative proceeding by reason of the User’s breach of these Terms, violation of any applicable law or infringement of any third party’s rights, the User shall, at its own expense, defend Delta and its affiliates, directors, managerial officers, employees, agents and licensors, and shall indemnify them against all losses, damages, liabilities and expenses arising therefrom (including reasonable attorneys’ fees and litigation costs).

The Materials and their documentation are commercial computer software and commercial computer software documentation. Government agencies or their contractors that acquire the Materials obtain the same rights as any other ordinary end user and are bound by these Terms.

In the event of a breach of these Terms, Delta may terminate the license immediately without further notice.

1. Upon termination of these Terms, the User shall immediately cease use of the Materials and shall delete and destroy the Materials and all copies and components thereof; upon Delta’s request, the User shall confirm in writing that such deletion has been completed.

2. The provisions of Articles 11, 12, 14, 15, 16 and 17, and of Articles 19 through 29, shall remain in full force and effect after termination of these Terms.

1. Delta may amend these Terms at any time and shall publish the amended version on its official website; the amendment shall take effect on the date of publication or on the effective date stated in the amended version.

2. A User that continues to use the Materials after an amendment takes effect shall be deemed to have fully and irrevocably agreed to all provisions of the amended Terms. A User that does not agree to the amendment shall cease use of and delete the Materials.

1. The User shall not assign, transfer or otherwise dispose of all or any part of its rights and obligations arising under these Terms to any third party without Delta’s prior written consent; any assignment or transfer in breach hereof shall be of no effect.

2. Delta may assign its rights and obligations arising under these Terms to its affiliates or to any third party that assumes the relevant business of Delta as a whole.

Where Delta fails to perform or delays in performing its obligations under these Terms due to an act of God, war, civil disturbance, epidemic, governmental order, power or network interruption, third-party service interruption or any other cause not attributable to Delta, Delta shall not be liable for breach of contract.

If any provision of these Terms is held invalid, unlawful or unenforceable by a court of competent jurisdiction, such provision shall be excluded to the minimum extent necessary, or shall be replaced by a provision that is lawful, valid and closest to the true intent of the parties, and the remaining provisions shall continue in force and be binding.

Delta’s delay in exercising or failure to exercise any right, power or remedy under these Terms shall not constitute a waiver of such right, power or remedy; nor shall any single or partial exercise thereof preclude any subsequent or other exercise of any right, power or remedy.

These Terms (including the annexes, policies and announcements published on Delta’s official website and constituting part of these Terms) constitute the entire agreement between the User and Delta with respect to the Materials, and supersede all prior and contemporaneous oral or written understandings and agreements between the parties.

Notices given by Delta to the User may be effected by publication on the official website, by displaying a message within the software, or by sending to the email address provided by the User, and shall be deemed served upon dispatch.

These Terms shall be governed by the laws of the place of Delta’s registration and construed in accordance therewith.
