The Software licensed by the Vendor is exclusively available from the Atlassian Marketplace at and the Vendor is entitled to grant sub-licenses to use the Software through the Atlassian Marketplace.  
The following terms apply to the contractual relationship between the Vendor and the acquirer of a sub-license to use the Software (hereinafter: Buyer) on the Atlassian Marketplace (hereinafter: License).

If the Buyer gets access to the Software available on the Atlassian Marketplace via a telecommunications connection and the data generated by the use of the Software and/or the data required for the use of the Software including the respective and necessary licensing of the Software. However, the offer to get access to and license the Software is directed exclusively to legal entities under public law, special legal funds under public law, or entrepreneurs.

This agreement (hereinafter: Agreement) sets out the terms upon which the Software is licensed and may be used by the Buyer. The term “Buyer” also includes its employees, agents and affiliated companies. The terms of this Agreement apply when the Buyer first downloads, installs, or uses the Software, whichever occurs first. The Buyer will require a current and valid License key or active subscription to use and continue to use the Products. If the Buyer does not agree to the terms of this Agreement, the Buyer shall not download, install or use the Software or any services related to them.

The Software is protected by international copyright laws. The rights of use concerning the Software are subject to this Agreement and the Atlassian Cloud Terms of Service. Any conflicting, deviating, or supplementary provisions proposed by the Buyer shall not become part of the Agreement unless the Vendor expressly agrees to their validity in writing. This preamble and the provisions contained therein are also part of this Agreement.

1. Object

This Agreement grants permission to use of the Software and to receive maintenance services. An overview of the current Software that the Vendor offers on the Atlassian Marketplace can be found on the Software listing on the Atlassian Marketplace (hereinafter: Documentation).

Services associated with the Software are mainly supplied within the Atlassian Cloud environment (hereinafter: “Atlassian Cloud”). The Vendor does not have direct access to the Buyer’s data, other than for short time to supply Cloud Services. This includes diagram creation, editing, and storage and all other data produced with the Software by the Buyer in the Atlassian Cloud (hereinafter: Application Data). The hosting services are provided by the Vendor (hereinafter: Hosting Provider). Most provisions about the availability of services here refer to the Hosting Provider. The Vendor has no influence over the Atlassian Cloud. Please refer to the Atlassian Cloud Terms of Service for the core features.

This Agreement covers the most current version of the Software from the beginning until the end of the term (see §3).

Other services, including but not limited to installation, instruction, training, customization of the Software, or any other service, are not part of this Agreement. If the Vendor offers such services, they are to be agreed upon separately in writing.

2. Right of Use, Multiple Use, and Use on Networks

The Vendor grants the Buyer a non-exclusive, non-transferable a) sub-license to use the Software; and b) permission to use the Cloud Services, both as acquired from an approved source, for the direct benefit of the Vendor during the term of this Agreement and as set out in Buyer's License specifically acquired (see §3) and this EULA (collectively, the “Usage Rights”). “Cloud Service” means that the Hosting Provider is hosting the Software or parts of it as a software-as-a-service for the Buyer. This “Cloud Service” is an image generation service. It should not be confused with the cloud service that Atlassian is offering. The Atlassian Cloud Service is clearly described as from Atlassian in this document. 

These Usage Rights may only be exercised by the maximum number of users for whom the Buyer owns an Atlassian core software license(s) such as Confluence and/or Jira.

It is prohibited to provide the Software to more users than contractually agreed. A higher user-number package must be purchased if the number of users exceeds the contractually agreed upon number of users. The Buyer agrees to pay the difference through a new transaction in the Atlassian Marketplace (upgrade).

The Vendor shall make sure that the Cloud Services are available for use on a central data processing system that is not part of the Atlassian Cloud (hereinafter: Server).

All Application Data remains on the Atlassian Cloud. The Software is a JavaScript program run in the web browsers of the users. For this reason, the Vendor and all its partners have no access to the Application Data.

When Cloud Services are performed and the Vendor needs to process Application Data temporarily, the Vendor shall make sure that the service has available processing capacity.  The Software will be available in accordance with the Atlassian availability standards.

The point of interconnection for the Software and Application Data is, in most cases, the user’s web browser. For the rare cases of server-side activities, it is the exit router of the Vendor's data center. The Vendor is neither responsible nor liable for the quality of the necessary hardware and software utilized by the Buyer nor for the telecommunications connection between the Buyer and the Vendor up to the point of interconnection. Especially for browser software, the Vendor requires the Buyer to use current versions of major internet browsers and at least those web browsers required by Atlassian for their core products.

3. Term

The Buyer may choose the term of the Agreement on the Atlassian Marketplace according to the options available there. The term is automatically extended by the length of the initially selected term unless either party terminates the Agreement at the end of the term (“the Term”). The right of each party to extraordinary termination for good cause shall remain unaffected. The Agreement can be terminated by clicking the corresponding button "Unsubscribe" for this Software within the administration of the basic Software. 

Initially, the Buyer is entitled to test the Software free of charge for 30 days (subject to change by Atlassian). During this period, the Vendor is not obliged to provide any support or maintenance services. During this period, the Vendor's liability is excluded to the extent permitted by law.

4. Resale, Transfer, or Sublicensing

The Buyer may not transfer, sell, rent, lease, sublicense, re-license or assign the Software in any way. In particular, the Buyer shall not be entitled to transfer access to the Software to third parties other than specified by the terms of the Atlassian Marketplace. The Buyer shall take the necessary precautions to guarantee that unauthorized third parties cannot access the Software and/or the Application Data.

5. Open Source Software

If Open Source Software is used in the Vendor’s product, it will not materially or adversely affect the Buyer’s ability to exercise Usage Rights in the Software.

6. Cloud Services

The Buyer will not intentionally (a) interfere with other customers’ access to, or use of, the Cloud Service, or with its security; (b) facilitate the attack or disruption of the Cloud Service, including a denial of service attack, unauthorized access, penetration testing, crawling, or distribution of malware; (c) cause an unusual spike or increase in Buyer’s use of the Cloud Service that negatively impacts the Cloud Services operation, or (d) submit any information that is not contemplated in the applicable Documentation.

7. Ownership

The Buyer does not acquire any rights or permissions other than by the license granted by this License to use the Software for the Term, in particular, does not become the owner of marketing materials, any Software or electronic media, intellectual property rights, methodologies, strategies, research, and designs. The Vendor reserves the right to use in any way it wishes any programming tools, skills, content, methodologies, strategies, and techniques acquired or used in performing its duties under this License.

The ownership of Application Data created using the Software shall remain with the author of that content.

8. Maintenance Services

In summary, the Vendor offers the following services to the Buyer free-of-charge for the Software during the Term:

  • The Buyer will get Software updates (updates) released in the way defined by Atlassian, when updates are released by the Vendor

  • The Vendor shall provide the Buyer with technical support for troubleshooting and error (as defined in clause 10.2) resolution (hereinafter: "Software Maintenance") for the Software as set out in clause

  • 10.1 during the support hours referred to in clause 11.3 via the support channels listed in clause 9.

Full particulars of these services are set out below in clauses 12, 13, and 14.

9. Official Support Channels

The Vendor offers the following support channels:

  • A publicly accessible documentation

  • A publicly accessible helpdesk for registering new support tickets

  • Direct email support via support

The Vendor endeavours to be easily available during the support hours set out in paragraph §11.3  below, via email, chat, Atlassian forums, Vendor’s forums, social media, and other channels. However, availability is at the discretion of the Vendor.

10. Included Services

The Vendor offers the following services during support hours (please see clauses 12, 13, and 14 for full particulars of these services):

  • Investigation of problems with the Software,

  • Analysis of errors (as defined in clause 10.2) and investigation of the underlying causes of the reported problems (root cause analysis)

The limited services as mentioned above comprise the entirety of the Vendor's obligation to provide support services. Furthermore, the Vendor is not obliged to provide further services. In particular, the Vendor is not obliged to provide installation, customization, programming, consulting, and training services. If the Vendor offers such services, they are to be paid for and agreed upon separately in writing. If additional services are offered for free as a courtesy, this does not imply any obligation for the future. If additional services are offered for free as a courtesy, the Vendor's liability is excluded to the extent permitted by law.

The Vendor shall use reasonable endeavors to resolve documented, reproducible errors in the Software (Software Maintenance) using competent personnel and according to accepted industry standards. The Vendor is not responsible for the success of the resolution of errors and gives no guarantee in this respect. For this License, an ‘error’ is a material non-compliance between the functionality of the Software with the Documentation for the Software, reported by the Buyer, which occurs other than by user error. If an error cannot be reproduced by the Vendor, it is not considered an error. The non-compliance has to cause a loss of functionality permanently and significantly. In this case, the parties shall endeavor to reach an agreement on the action to be taken.

The Vendor is exempted from the obligation to perform Software Maintenance for the Buyer (without affecting the payment obligation for the agreed purchase price of the Software), particularly:

  • in the event of errors resulting from unauthorized modifications or alterations to the Software (both server-side and client-side);

  • if the installation of the current or previous Software versions, as well as the delivered error solutions, were not carried out, unless the delivered versions of error solutions are faulty;

  • for Software versions released a period (e.g., more than one month) before the Buyer reported the error. This timeline is dependent on if and how Atlassian allows the Buyer to hold back updates (“Release Track”) for their instances in the Atlassian Cloud.

  • in the event of errors due to the unauthorized use of the Software or incorrect operation, unless the Software is used following the user Documentation;

  • for Software provided by the Vendor that is no longer developed or supported (end-of-life status), is intended to be used for test purposes and is, therefore, an unfinished version of the Software (beta version), is created as a final test version (release candidate), and/or is a development version (development release) or used as a free version;

  • for any hardware defects;

  • when the Software is used on hardware, software (not limited to but especially not current web browsers), and operating system environments other than those specified in the user documentation;

  • in the event of disruptions caused by force majeure or similar circumstances;

  • alterations to the Software made by the Buyer in breach of this Agreement;

  • alterations to the Software, performed by technicians outside of the Vendor without the Vendor's prior written consent.

If the Vendor offers such services, they are to be agreed upon in writing and paid for separately.

The Buyer shall understand that neither the Vendor nor the Hosting Provider store any Application Data and thus the Buyer shall undertake adequate data backup measures to ensure that any data to be recovered is stored in a machine-readable format and that the Buyer can recover with minimum effort. Atlassian offers the following guidelines for Atlassian’s Jira Cloud backups and Confluence Cloud backups.

11. Error Reporting, Obligation to Cooperate, and Support Hours

The Buyer must immediately report any errors that may occur with a detailed description of the problem using the support channels listed in clause 9.

For the execution of the contractual services, cooperation by the Buyer must be complete and punctual. The obligation to cooperate includes the following items in particular:

  • The Buyer must observe all applicable laws and regulations. It is prohibited to transfer data or content to the Vendor's Servers that violate legal provisions or infringe third-party property rights or copyrights, or other rights of third parties.

  • When reporting an error, all documentation, log files, and other information relevant to troubleshooting shall be made available without delay;

  • Only data free from computer viruses or other harmful code may be transmitted;

  • The Buyer may use no software, technologies, or procedures in connection with the use of the contractual Software that is capable of affecting its operation, security, and availability.

To transmit error reports, the Buyer can reach the Vendor during support hours on workdays between 09:00 and 17:00 (GMT+2). Workdays include Monday to Friday. The Vendor reserves the right to change support times as needed.

The support cases’ processing, considering the reaction and solution times specified in clauses 13, 14, shall be carried out during the support hours specified in paragraph 11.3.

12. Error Classification Levels

In the case of error reports, the Vendor will use reasonable endeavors to ensure that the processing of the support cases is carried out within the response and resolution times specified in clauses 13, 14. The response and resolution times depend on the classification level; the following error classification levels apply:

  • Priority 1: Critical error. The use of the whole or a material part of the Software is impossible or significantly restricted. A significant limitation exists where the whole or a material part of the Software no longer works, and no functional workaround can be achieved (“significant limitation”).

  • Priority 2: Other disturbances. Any other problems with the Software.

The Vendor will use reasonable endeavors to handle all support cases within the time periods set out below. Priority 1 errors are given priority over priority 2 errors, irrespective of the time they were registered in the support system.

13. Response Time

Response time is the period between the report of an error and the first action taken by the Vendor. The period starts with receiving the corresponding support request through an official support channel according to clause 9 within the support hours specified in clause 11.3. and runs exclusively during the agreed support hours. If a message appears outside the agreed support hours, the response time begins with the next support period.

The Vendor will use reasonable effort for the following response times according to the error level: Priority 1: 4 hours and Priority 2: 8 hours.

The response times are the Vendor's declared aspiration. In particular, regarding the provision of clause 12.2., the Vendor does not guarantee the observance of the stated response times. Non-compliance with these response times does not constitute any right for the Buyer to reduce the price, claim for reimbursement, terminate the Agreement, or seek any other form of compensation.

14. Resolution Time

The resolution time is the maximum time before troubleshooting resolves the error or a workaround is implemented after the start of work on a support case.

The Vendor will use all reasonable business efforts for the following resolution times according to the error classification levels: Priority 1: 16 hours and Priority 2: 40 hours.

The response times are the Vendor's target resolution times over the average of the last 5 incidents of that priority level. Any specific incident resolution time will vary. In particular, regarding the provision of clause 12.2., the Vendor does not guarantee the observance of the stated average response times. Non-compliance with these response times does not constitute any right for the Buyer to reduce the price, claim for reimbursement, terminate the Agreement, or seek any other form of compensation.

15. Limitation of liability

The Vendor shall be liable for damages resulting from this Agreement, for whatever actual or legal reasons, only under the following regulations:

In the case of willful intent, gross negligence or in the case of a loss of life or personal injury, the Vendor shall be liable without restriction under statutory provisions.

Insofar as the Vendor culpably infringes an essential contractual obligation, the liability for all cases shall be limited to the foreseeable damage at the time of conclusion of the Agreement up to a total amount for all damages per calendar year, which corresponds to 100% of the purchase price paid by the Buyer in this calendar year, as far as the Buyer can prove the damage. Such a fundamental obligation will always exist, where the obligation is essential for the due and proper implementation of the Agreement, and on which the Buyer trusted and could reasonably rely. This limitation of liability also applies to data loss and data corruption. An essential contractual obligation in the meaning of this Agreement is any obligation the fulfillment of which necessarily enables the proper performance of the Agreement and the observance of which the other party of the Agreement regularly relies on.

Liability is excluded in the event of negligent violation of other non-essential contractual obligations and (where appropriate laws authorize) in respect of indirect and/or consequential losses including but not limited to special damage even if the Vendor was aware of the circumstances in which such special damage could arise; loss of profits; loss of anticipated savings; loss of business opportunity; loss of goodwill; loss or corruption of data.

The Vendor will indemnify and hold the Buyer harmless from any claim, suit, or proceeding brought against it based on a claim that the Vendor has infringed or is infringing any third party's trademark, copyright, patent, or other intellectual property right in or concerning the Software. The maximum damage that the Vendor is liable for is limited as in clause 15.2.

The Vendor shall not be liable for the loss of Application Data insofar as the damage is due to the Buyer failing to carry out data backups, thereby ensuring that the Buyer can restore lost data with reasonable effort.

The Buyer will indemnify and hold the Vendor harmless for any claim, suit or proceeding brought against it based on (i) any breach by the Buyer of applicable data protection laws; and/or (ii) any infringement of the intellectual property rights.

16. Fees

All costs for the Software are defined in the Atlassian Marketplace. In the Atlassian Marketplace, the Buyer purchases and pays directly unless they work with an Atlassian Solution Partner. 

17. Defects

In case of a defect (which is not an ‘error’) of the Software, the Vendor shall in its sole discretion remedy the defect immediately or to deliver a replacement free of defects if the Buyer notifies the Vendor of the defect. Claims based on a defect shall become statute-barred within one year of the Software being provided by the Vendor.

18. Warranty

The Vendor also guarantees that it is entitled to grant the sublicense in accordance  with this License.

The Vendor does not accept any additional guarantees.  All other conditions, warranties, or other terms which might have effect between the parties or be implied or incorporated into this License, whether by statute, common law, or otherwise, are hereby excluded, including the implied conditions, warranties, or other terms as to the satisfactory quality, fitness for purpose or the use of reasonable skill and care.

Warranty claims shall become statute-barred within one year of the Software being provided by the Vendor.

19. Export and Import Control 

The license and services under this Agreement may be subject to export and import restrictions in certain countries. The Buyer shall comply with the applicable export and import control regulations. The performance of the Agreement by the Vendor is subject to the provision that there are no obstacles to performance due to national and international export and import law provisions or any other statutory provisions.

20. Termination

The Vendor shall be entitled to terminate the obligation of providing the Software Maintenance (clause 8) without notice if, in particular: the Buyer breaches their obligations under this Agreement and if, despite an appropriate grace period with a rejection warning, they do not put an end to the breach or demonstrate that appropriate measures have been taken to suitably prevent the repetition of the breach of contract in the future. 

The right to extraordinary termination for good cause (§ 314 BGB) remains unaffected.

22. Publicity

The Vendor shall not use any trade name, trademark, service mark, logo or commercial symbol, or any other proprietary rights of Buyer or any of its affiliates in any manner without prior written authorization. Vendor
shall not issue any press release, other publicity, or promotional materials that relate to Buyer, its affiliates, or this Agreement.

23. Miscellaneous

The Vendor is not responsible or liable for any failure or delay in the performance of its obligations under this Agreement arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, epidemics, pandemics or an outbreak of infectious disease, quarantines, national or regional emergencies, civil or military disturbances, nuclear or natural catastrophes and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services (“Force Majeure”); it being understood that the Vendor is to use commercially reasonable efforts that are consistent with accepted practices in the software industry to resume performance as soon as practicable under the circumstances.

All agreements are contained within this contract.

The applicable law and the place of jurisdiction for all disputes arising out of or in connection with the Agreement shall be Novi Sad (Serbia) under the law of Serbia. The United Nations Convention on Contracts for the International Sale of Goods of 11 April 1980 (CISG) shall not apply.

Should a provision of this Agreement be or become invalid, all other provisions shall remain unaffected. Such an invalid provision shall be replaced with a provision in line with the intention that the parties could reasonably attribute to the Agreement at the time of entering into said Agreement.
