Virtuozzo End-User License Agreement

Updated May 2021

This End-User License Agreement (this “Agreement”) is a legal contract between you, as either an individual or an Entity (as defined below), and Virtuozzo International GmbH (“Virtuozzo”). Read the terms and conditions of this agreement carefully before downloading, installing, obtaining a license key, or otherwise accessing or using virtuozzo’s proprietary software accompanied by this agreement (the “software”). The software is copyrighted and it is licensed to you under this agreement, not sold to you. By downloading, installing, obtaining a license key, or otherwise accessing or using the software, you acknowledge that you have read this agreement, that you understand it, and that you accept and agree to be bound by its terms. If you are accepting this agreement on behalf of a company, organization, educational institution, or agency, instrumentality or department of a government (an “entity”) as its authorized legal representative, then you represent and warrant that you have the power and authority to bind such entity to these terms, and references to “you” herein refer to both you, the individual end user, and the entity on whose behalf you are accepting this agreement. If at any time you are not willing to be bound by the terms of this agreement, you should click the “i do not accept” or similar button, terminate the download and/or installation process, immediately cease and refrain from accessing or using the software and delete any copies you may have. This agreement, along with any additional terms or policies incorporated herein by reference, represents the entire agreement between you and Virtuozzo concerning the software, and this agreement supersedes and replaces any prior proposal, representation, or understanding you may have had with Virtuozzo relating to the software, whether orally or in writing.

1. License.

1.1. Grant of License. Subject to your full and ongoing compliance with the terms and conditions of this Agreement, including without limitation payment of all applicable license fees, the applicable Virtuozzo entity from which you obtained the Software hereby grants to you, and you accept, a personal, limited, nonexclusive, non-transferable (except as set forth in Section 1.5 below), non-assignable, revocable license to use the Software during the Term (as defined below) in machine-readable, object code form only, and the user manuals accompanying the Software (the “Documentation”), only as authorized in this Agreement. For purposes of this Agreement, the “Software” includes any updates, enhancements, modifications, revisions, or additions to the Software made by Virtuozzo and made available to end-users. Notwithstanding the foregoing, Virtuozzo shall be under no obligation to provide any updates, enhancements, modifications, revisions, or additions to the Software.

1.2 Scope of Use. Your license to use the Software is conditioned on the following license restrictions, and any use of the Software in violation of any of these restrictions, or any of the other terms of this Agreement is a breach of this Agreement and is unlicensed. You may use one copy of the Software activated by a license key on a single device owned, leased, or otherwise controlled by you, at a single time (the “Authorized Device”). If you have multiple license keys for the Software, you may install and use as many copies of the Software as you have license keys, in each case, on an Authorized Device and only as authorized herein. For purposes of this Agreement, “use” of the software means loading the Software into the temporary or permanent memory of an Authorized Device. Installation of the Software on a network server solely for distribution to other computers is not “use” of the Software, and is permitted, provided that you have a valid license key for each Authorized Device on which the Software is installed. The Software may not be used on, distributed to, or installed on a greater number of computers than you have license keys. If you use or distribute the Software to multiple users, you must ensure that the number of Authorized Devices does not exceed the number of license keys you have obtained, or you will be in breach of this Agreement and such use and distribution is unlicensed.

1.3. Evaluation Licenses. In the event you obtained a trial or evaluation version of the Software, it will come with a trial activation key that activates the Software for a limited time period (the “Trial Period”). You may use the Software during the Trial Period for internal non-commercial purposes, solely to evaluate the suitability of the Software for your needs. Upon the expiration of the Trial Period you must either purchase an activation key or destroy the Software, Documentation, all backup copies thereof, and all trial activation keys that you have obtained. If you do not purchase an activation key prior to the expiration of the Trial Period, this Agreement, and all your rights and licenses hereunder will terminate at the expiration of the Trial Period.

1.4. Copies and Modifications. Except and solely to the extent that such a restriction is prohibited under applicable law, you may not reverse engineer, decompile, disassemble, or otherwise translate the Software or any license keys you have obtained. You may not modify or adapt the Software or any license keys that you have obtained in any way. Any such copies of the Software, Documentation, or license keys shall include any copyright or other proprietary notices that were included on such materials when you first received them. Except as authorized in this Section, no copies of the Software, Documentation, or license keys, or any portions thereof, may be made by you or any person under your authority or control.

1.5. Assignment of Rights. You will not sublicense, lease, rent, or lend your rights in the Software, Documentation, or license keys, as granted by this Agreement, without prior written consent of Virtuozzo, except that you may transfer this Agreement in full in connection with the sale of all or substantially all of the assets related to this Agreement, provided that the assignee assumes all of your obligations hereunder, and the licenses granted hereunder will only extend to use of the Software on the Authorized Device on which the Software was installed immediately prior to the assignment. Virtuozzo may assign this Agreement without limitation. Any assignment in violation of the foregoing shall be void and of no effect. Subject to the foregoing, this Agreement shall bind and inure to the benefit of the parties and their respective successors and permitted assigns.

1.6 Support and Maintenance Services; Updates; Upgrades. Virtuozzo will not provide any support or maintenance services under this Agreement. You acknowledge that Virtuozzo has no express or implied obligation to announce or make available any updates, enhancements, modifications, revisions, or additions to the Software and that this Agreement does not give you any rights in or to any of the foregoing. Virtuozzo may offer support and/or maintenance services separately. If you have purchased Virtuozzo support and/or maintenance services with the Software, these services are provided to you under the terms and conditions accompanying the applicable service. Any supplemental software code or related materials that Virtuozzo provides to you as part of any support and/or maintenance services are considered part of the Software and are subject to the terms and conditions of this Agreement. If you purchase an upgrade (a new version of the Software) from a perpetual license to a newer version of the perpetual license, then your license keys to the prior perpetual license will continue to operate. However, if you purchase an upgrade from a perpetual license to a term-based license, then the license keys to the perpetual license will terminate upon activation of the term-based license.

2. Intellectual property and confidentiality.

2.1. Use Reporting, License Violations and Remedies. Virtuozzo reserves the right, and you authorize Virtuozzo, to gather data on key usage including license key numbers, Authorized Device IP addresses or other applicable device identifier (including MAC address or UDID), domain counts and other information deemed relevant, to ensure that our products are being used in accordance with the terms of this Agreement. Virtuozzo reserves the right to remedy violations of any of the terms of this Agreement immediately upon discovery, by charging the then current list price of unauthorized keys to the payment instrument used to make the original, authorized purchase, or by any other means necessary, including remotely disabling the Software. You agree not to block, electronically or otherwise, the transmission of data required for compliance with this Agreement. Any blocking of data required for compliance under this Agreement is considered to be violation of this Agreement and will result in immediate termination of this Agreement pursuant to Section 4.

2.2. License Expiration. Your license may include an expiration date that can result in the termination of the license. If your license key is stolen, or if you suspect any improper or illegal usage of your license outside of your control you should promptly notify Virtuozzo of such occurrence. A replacement license will be issued to you and the suspect license will be allowed to expire. For lease licenses, your monthly payment for each month must be processed prior to the expiration date in order for the license updates to be performed. For your convenience Virtuozzo may, but has no obligation to, provide license expiration warnings in the product interface. It is your responsibility to contact Virtuozzo regarding any potential expiration that you deem inappropriate. Virtuozzo shall not be liable for any damages or costs incurred in connection with the expired licenses.

2.3. Proprietary Rights to Software and Trademarks. You acknowledge that the Software and the Documentation are proprietary to Virtuozzo, and the Software and Documentation are protected under United States copyright and other intellectual property laws and international treaties. You further acknowledge and agree that, as between you and Virtuozzo, Virtuozzo and its third-party licensors own and shall continue to own all right, title, and interest in and to the Software and Documentation, including associated intellectual property rights under copyright, trade secret, patent, or trademark laws. Except for the limited, revocable license expressly granted to you herein, this Agreement does not grant you any ownership or other right or interest in or to the Software or the Documentation or any other intellectual property rights of Virtuozzo, whether by implication, estoppel, or otherwise. Any and all trademarks or service marks that Virtuozzo uses in connection with the Software or with services rendered by Virtuozzo are marks owned by Virtuozzo. This Agreement does not grant you any right, license, or interest in such marks, and you shall not assert any right, license, or interest in such marks or any words or designs that are confusingly similar to such marks.

2.4. Confidentiality. You shall permit only authorized users, who possess rightfully obtained license keys, to use the Software or to view the Documentation. Except as expressly authorized by this Agreement, you shall not make available the Software, Documentation, or any license key to any third party, or use the Software, Documentation, or any license key for any purpose other than exercising rights expressly granted to you hereunder. You agree to cooperate with and assist Virtuozzo in identifying and preventing any unauthorized use, copying, or disclosure of the Software, Documentation, or any portion thereof.

2.5. Virtuozzo right to Use Data. Our use of personal data and our use of cookies are described in full in our Privacy Policy and Cookies Policy.

You agree that Virtuozzo may collect and use technical data and related information—including but not limited to technical information about your device, system and application software, and peripherals—that is gathered periodically to facilitate the provision of software updates, product support, and other services to you (if any) related to the Software. Virtuozzo may use this information, to operate, provide, improve, and develop our products, services and technologies, to prevent or investigate fraudulent or inappropriate use of our products, services, and technologies, for research and development, and for the other purposes described in this Agreement (and the Privacy Policy and the Cookies Policy) or to you as part of our products and services. Virtuozzo’s websites and online services may use “cookies,” which enable you to personalize your experience on Virtuozzo’s sites and provide information to Virtuozzo such as which websites have been visited and which ads and web searches are effective. If you want to disable cookies, check your browser settings.

2.6. Audit Rights. During the term of this Agreement and for two (2) years after termination or expiration of this Agreement, Virtuozzo may audit, upon written notice to you, your books, records, and computing devices to determine your compliance with this Agreement and your payment of the applicable license fees, if any, for the Software. In the event that any such audit reveals an underpayment by you of more than five percent (5%) of the license fees due to Virtuozzo in the period being audited, or that you have breached any term of this Agreement, then, in addition to any other rights and remedies Virtuozzo may have, you will promptly pay to Virtuozzo any underpayments plus the cost of the audit.

3. License Fees. The Software will be available to you for use upon your receipt of one or more license keys. Upon acceptance of this Agreement, you may obtain one or more license keys by paying the requisite license fees, using the procedure set forth on Virtuozzo’s web site. License fees for term-based licenses are due prior to the commencement of the applicable term, and may be re-billed to the payment instrument you used for your initial purchase upon the commencement of any renewal term. Your license to the Software will terminate automatically without notice if you notify Virtuozzo in advance that you do not intend to renew a term-based license or if you fail to pay a renewal fee for a term-based license. The license fees paid by you are paid in consideration of the license granted under this Agreement. License sales are final and Virtuozzo does not refund license fees under any circumstances. By accepting this Agreement you fully understand that once license fee payment is made to Virtuozzo you will have no recourse for receiving a refund of any part of the fees.

4. Term and Termination. This Agreement is effective upon your acceptance of the Agreement, or upon your downloading, installing, accessing, and using the Software, even if you have not expressly accepted this Agreement. This Agreement shall continue in effect until expiration or termination as provided herein (the “Term”). Term-based licenses terminate upon the expiration of the prepaid term, unless you have paid all applicable fees to extend the term. Without prejudice to any other rights, this Agreement will terminate automatically without notice to you if you breach or fail to comply with any of the limitations or other requirements described herein, including the payment of any applicable fees, and you agree that in any such case Virtuozzo may, in addition to any other remedies it may have at law or in equity, remotely disable the Software. You may terminate this License Agreement at any time by providing written notice of your decision to terminate the Agreement to Virtuozzo and ceasing use of the Software and Documentation. Upon any termination or expiration of the Agreement for any reason, you agree to uninstall the Software and either return to Virtuozzo the Software, Documentation, all copies thereof, and all license keys that you have obtained, or to destroy all such materials and provide written verification of such destruction to Virtuozzo.

5. Indemnification. You will, at your own expense, indemnify and hold Virtuozzo, and all officers, directors, and employees thereof, harmless from and against any and all claims, actions, liabilities, losses, damages, judgments, grants, costs, and expenses, including reasonable attorneys’ fees (collectively, “Claims”), arising out of any use of the Package (as defined below) by you, any party related to you, or any party acting upon your authorization in a manner that is not expressly authorized by this Agreement.
