End User License Agreement

The license agreement governing all KSTRLWORKS software

Effective Date: July 25, 2026 Updated Date: July 25, 2026

BINDING AGREEMENT - READ CAREFULLY

THIS END USER LICENSE AGREEMENT (“AGREEMENT” OR “EULA”) IS A LEGALLY BINDING CONTRACT BETWEEN YOU AND KSTRLWORKS. BY INSTALLING, ACTIVATING, ACCESSING, OR USING ANY KSTRLWORKS SOFTWARE, YOU AGREE TO BE BOUND BY THIS AGREEMENT.

If you do not agree, do not install, activate, access, or use the Software. If you are entering into this Agreement on behalf of a company or other legal entity, you represent that you have the authority to bind that entity, and “you” refers to both you and that entity.

This Agreement applies to every product KSTRLWORKS distributes, whether licensed as a subscription, as a one-time or perpetual purchase, or offered free of charge. It works together with our Terms of Service and Privacy Policy. Where this Agreement and the Terms of Service both address the license to use the Software, this Agreement controls.

Plain-Language Summary

This summary is provided for convenience only. It is not part of the Agreement and does not modify it. The numbered sections below are what govern.

You get a license, not ownership. We license the Software to you. We keep all rights we do not expressly grant.
Your license can be revoked. This is true even for one-time or “lifetime” licenses if you break the rules.
Personal covers private use. Any use for or that facilitates financial gain needs a Commercial license. What matters is how the Software is used, not who paid for it.
Do not crack, resell, reverse engineer, or share your license. These self explanatory.
Some products include open-source components. Those components keep their own licenses, and nothing here takes away rights you have under them.
The Software respects your privacy. No telemetry, no analytics, and no log collection. Crash reports and error logs never leave your machine, and we never collect your files or work. The details are in our Privacy Policy.
The Software is provided as-is, and our liability is limited, as set out below.

1. Definitions

“KSTRLWORKS,” “we,” “us,” “our” means KSTRLWORKS, the licensor of the Software.
“You,” “your,” “User” means the individual or entity that installs, activates, accesses, or uses the Software.
“Software” means any and all software products, applications, drivers, libraries, tools, command-line utilities, and hosted services published, distributed, or made available by KSTRLWORKS, whether installed locally in object or executable form or accessed remotely, together with any Updates and Documentation. This includes HardPass and every other current or future KSTRLWORKS product.
“Documentation” means the user guides, manuals, and materials we provide for the Software.
“License” means the right to use the Software granted under Section 3, subject to the license model, edition, and tier you obtained.
“License Key” means any key, token, credential, or entitlement we issue to activate or verify a License.
“Subscription License” means a License granted for a recurring, time-limited term, including any software-as-a-service or hosted offering.
“Perpetual License” means a License obtained through a one-time payment for continued use rights, subject to this Agreement.
“Free Edition” means any edition, tier, or trial of the Software offered at no charge.
“Personal License” and “Commercial License” have the meanings given in Section 4.
“Updates” means patches, bug fixes, new versions, and upgrades to the Software that we choose to make available.
“Device” means a single physical or virtual computer.

2. Acceptance

Your acceptance of this Agreement occurs when you take any of the following actions:

Install, activate, or launch the Software
Access or use the Software or any Free Edition in any manner
Create an account, purchase a License, or download the Software

By taking any of these actions, you acknowledge that you have read, understood, and agree to be bound by this Agreement. You further represent that you have the legal capacity to enter into a binding contract and that you meet the minimum age requirements described in our Privacy Policy. If you received a License Key or access from any source other than KSTRLWORKS or our authorized payment processors, you are not licensed under this Agreement and must not use the Software.

3. License Grant

3.1 General Grant

Subject to your continuous compliance with this Agreement and your payment of all applicable fees, KSTRLWORKS grants you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable License to install and use the Software in object code form, or to access and use it where we provide it as a hosted service, for your own use in accordance with the license model, edition, and tier you obtained.

ALL LICENSES ARE REVOCABLE. Whether your License is a Subscription License, a Perpetual License, or a Free Edition, it remains revocable for any breach of this Agreement. The words “perpetual” or “lifetime” refer only to the absence of recurring payment obligations, not to irrevocability. Upon revocation or expiration, you must immediately stop using the Software and delete all copies in your possession or control.

3.2 Subscription Licenses

A Subscription License grants use rights for the paid term only. When the term ends or the subscription is cancelled or unpaid, the License ends and your access to the Software, or to the paid features it enabled, ends with it. Billing, auto-renewal, and cancellation are governed by our Terms of Service.

3.3 One-Time and Perpetual Licenses

A Perpetual License grants continued use rights for the version or versions covered by your purchase, subject to this Agreement. A Perpetual License does not entitle you to Updates, upgrades, or new major versions except as we expressly provide (see Section 7), and it remains revocable for breach as described in Section 3.1.

3.4 Free Editions and Trials

We may offer Free Editions at our discretion, and we may determine and verify eligibility. Free Editions are licensed for personal, non-commercial use only unless we state otherwise in writing. Free Editions may have reduced features, may be changed, limited, or discontinued at any time, and are provided with no support commitment and no warranty of any kind.

3.5 Seats, Devices, and Activation

Unless your order or the applicable product terms state otherwise, each paid License authorizes use by one User. You may be required to activate the Software and to keep your License Key confidential. You may not pool, share, or concurrently use a single License across multiple Users to exceed the scope you purchased.

3.6 Alpha, Beta, and Pre-Release Software

We may designate certain builds as alpha, beta, preview, or otherwise pre-release. Pre-release Software is provided for evaluation, may contain defects, may be unstable, and may be changed, suspended, or discontinued at any time without notice. Do not rely on pre-release Software for anything you cannot afford to lose. We may require you to update to a newer build, and we may expire or disable pre-release builds. Pre-release Software is provided strictly as-is, with no support commitment and no warranty of any kind, and your use of it is at your sole risk.

4. Personal and Commercial Use

Each License is issued as either a Personal License or a Commercial License, as identified at the time you obtain it.

A Personal License permits use of the Software only for private, personal, non-commercial purposes.
A Commercial License is required if you use the Software for any commercial purpose or to facilitate financial gain of any kind. Any use that generates, supports, enables, or contributes to financial gain is commercial use. This includes, without limitation:
- Use in, for, or in connection with any business, trade, profession, or organization
- Use by an employee, contractor, or agent acting on behalf of any organization
- Use that generates, supports, enables, or contributes to revenue, income, paid work, or monetary benefit, whether direct or indirect
- Use in the creation or production of any goods, services, or content that you sell, license, or are compensated for

This requirement is determined by how the Software is used, not by who purchases the License. It applies equally whether the License is obtained by an individual or by an entity. Purchasing or using a Personal License, including a Free Edition, does not grant any right to commercial use. If your use is or becomes commercial, you must obtain a Commercial License before continuing. Using the Software commercially without a valid Commercial License is a material breach of this Agreement.

5. License Verification and Anti-Piracy

The Software may require activation and may perform periodic license verification, including for offline-capable editions.

You must activate paid Licenses through our licensing system.
The Software may check with our servers to verify your License, even for offline use.
We may update, modify, deactivate, or blacklist any License Key at any time for security or enforcement purposes.
License Keys obtained from any source other than KSTRLWORKS or our authorized payment processors are invalid, and using or attempting to use a breached, stolen, resold, or otherwise unauthorized License Key is a material breach of this Agreement.
Attempting to bypass, disable, or interfere with license verification is strictly prohibited and will result in immediate termination without refund.

6. Restrictions

You shall NOT, and shall not permit or enable any third party to:

Reverse engineer, decompile, disassemble, or attempt to derive the source code, structure, or algorithms of the Software, except to the limited extent this restriction is prohibited by applicable law or expressly permitted by the license of an open-source component
Modify, adapt, translate, or create derivative works of the Software, except as expressly permitted by an applicable open-source component license
Remove, disable, circumvent, or tamper with any license, activation, security, or technological protection measure in the Software
Rent, lease, lend, sell, sublicense, distribute, transfer, or otherwise make the Software or your License available to any third party
Provide the Software’s functionality to third parties as a hosted or managed service, service bureau, or “as-a-service” offering where the core value delivered is the functionality of the Software
Distribute, publish, or upload the Software, License Keys, or “cracked” or patched versions on any file-sharing platform, marketplace, forum, or similar service
Share your account credentials, License Keys, or authentication tokens with anyone, or use the Software to exceed the seats, Devices, or scope you purchased
Act as an unauthorized reseller or distributor of the Software or Licenses. We do not authorize resellers.
Use the Software for any unlawful purpose or in violation of any applicable law or regulation
Use the Software commercially under a Personal License or Free Edition, as described in Section 4

7. Updates, Upgrades, and Versions

We may provide Updates at our sole discretion. Updates may be delivered automatically or require manual action, and may add, change, or remove features or change system requirements. Updates are provided on a best-effort basis with no guaranteed schedule, frequency, or backward compatibility.

For Subscription Licenses, Updates are provided for as long as the subscription is active. For Perpetual Licenses, Updates are limited to those we expressly include with the version you purchased, and new major versions may require a separate purchase. Any Update you install is governed by this Agreement unless it is accompanied by a separate license, in which case that license governs the Update.

8. Ownership and Intellectual Property

The Software is licensed, not sold. KSTRLWORKS and its licensors retain all right, title, and interest in and to the Software, including all code, designs, algorithms, trade secrets, trademarks, and Documentation, and all intellectual property rights therein. All rights not expressly granted to you in this Agreement are reserved by KSTRLWORKS. You gain no ownership interest in the Software by this Agreement or by your use of it.

You may not use KSTRLWORKS trade names, trademarks, logos, or other brand features without our prior written consent, and you may not represent yourself as a partner, affiliate, reseller, or representative of KSTRLWORKS.

Feedback. If you choose to send us suggestions, ideas, bug reports, or other feedback about the Software, you grant KSTRLWORKS a perpetual, irrevocable, worldwide, royalty-free right to use that feedback for any purpose, without restriction and without obligation or compensation to you. Feedback never includes your files or work product, which we do not collect.

9. Third-Party and Open-Source Components

Certain Software may include or depend on third-party or open-source software components, which may include, depending on the product, components such as QEMU, libvirt, and related virtualization technologies. Those components are licensed to you under their own respective license terms, not under this Agreement. To the extent any open-source license grants you rights that conflict with the restrictions in this Agreement, the open-source license governs solely with respect to that component, and nothing in this Agreement limits, restricts, or removes any right you have under such a license.

Where required, the applicable third-party and open-source license notices and, where required, corresponding source, are made available with the Software or on request at [email protected]. Third-party components are provided by their respective authors without warranty, and KSTRLWORKS is not responsible for them beyond what their licenses require.

10. Data, Privacy, and Telemetry

Our handling of personal data is governed by our Privacy Policy, which is incorporated into this Agreement by reference. In addition, and consistent with that policy:

No telemetry and no log collection. The Software does not collect analytics, usage tracking, behavioral data, or activity logs, and does not phone home except for the limited license verification and Update checks described in Sections 5 and 7.
Your work stays yours. The Software does not collect, transmit, or store your files, projects, documents, or work product. Any crash reports or error logs remain local to your Device unless you choose to send them to us.
Minimal licensing data. To verify Licenses, deliver Updates, and prevent abuse, we may process limited data such as account identifiers, non-identifying system information, and IP address, as described in the Privacy Policy.
You are responsible for your own environment, including backups of your data and systems, and for how you configure and use the Software.

11. Term and Termination

This Agreement is effective when you accept it and continues until terminated or until your License ends. Your License and this Agreement terminate automatically, without notice, if you breach any provision, and we may also suspend or revoke any License as described in Section 3.1 and in our Terms of Service.

Upon any termination or expiration, you must immediately stop all use of the Software and delete all copies in your possession or control. Termination does not entitle you to any refund. Sections that by their nature should survive termination, including Sections 4, 6, 8, 9, 12, 13, 14, 15, and 18, survive.

12. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KSTRLWORKS DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTY THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR THAT DEFECTS WILL BE CORRECTED. You assume all risk as to the quality, performance, and results of the Software, and as to any loss or corruption of data. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL KSTRLWORKS, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, including loss of profits, revenue, data, business, or goodwill, business interruption, cost of substitute goods, or system failures, arising out of or related to the Software or this Agreement, even if advised of the possibility of such damages and even if a limited remedy fails of its essential purpose.

KSTRLWORKS’ TOTAL AGGREGATE LIABILITY FOR ANY AND ALL CLAIMS ARISING OUT OF OR RELATED TO THE SOFTWARE OR THIS AGREEMENT SHALL NOT EXCEED THE AMOUNT YOU PAID TO KSTRLWORKS FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. For Free Editions, that amount is zero. These limitations apply regardless of the legal theory and to the fullest extent permitted by law. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

14. High-Risk and Critical Systems

THE SOFTWARE IS NOT DESIGNED OR INTENDED FOR USE IN HIGH-RISK OR LIFE-CRITICAL APPLICATIONS, including medical devices, life support, nuclear facilities, aircraft or vehicle navigation or control, or any environment where failure could lead to death, personal injury, or severe physical or environmental harm. You agree not to use the Software in any such application, and you assume all risk if you do.

15. Indemnification

You agree to indemnify, defend, and hold harmless KSTRLWORKS and its officers, directors, employees, agents, licensors, and affiliates from and against any and all claims, liabilities, damages, losses, costs, and expenses, including reasonable attorneys’ fees, arising from your use or misuse of the Software, your violation of this Agreement, your violation of any law, or your violation of any third-party rights. This obligation survives termination of this Agreement.

16. Export Compliance

The Software may be subject to export control laws of the United States and other jurisdictions. You agree to comply with all applicable export and import laws, and you represent that you are not located in an embargoed country, are not on any government list of prohibited or restricted parties, and will not export or re-export the Software in violation of applicable law.

17. U.S. Government End Users

If you are a U.S. Government end user, the Software is a “commercial item” as defined in 48 C.F.R. §2.101, consisting of “commercial computer software” and “commercial computer software documentation.” Consistent with 48 C.F.R. §12.212 and 48 C.F.R. §227.7202-1 through 227.7202-4, U.S. Government end users acquire the Software with only the rights set forth in this Agreement.

18. Governing Law, Venue, and Waivers

18.1 Governing Law

This Agreement and any dispute arising out of or related to it or the Software are governed by the laws of the State of New York, without regard to its conflict of law provisions.

18.2 Venue

Any action arising out of or relating to this Agreement or the Software shall be brought exclusively in the state or federal courts located in Albany County, New York. You submit to the personal jurisdiction of those courts, and you waive any objection to venue and any claim that those courts are an inconvenient forum.

18.3 Jury and Class Action Waiver

TO THE FULLEST EXTENT PERMITTED BY LAW, YOU AND KSTRLWORKS WAIVE ANY RIGHT TO A JURY TRIAL, AND ANY DISPUTE WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION.

19. Changes to this Agreement

WE MAY MODIFY THIS AGREEMENT AT ANY TIME IN OUR SOLE DISCRETION. When we do, we will update the “Updated Date” above, and for material changes we may, but are not obligated to, provide notice by email. The current version is always available on our website. Your continued use of the Software after a change takes effect constitutes acceptance of the modified Agreement. If you do not agree to the change, you must stop using the Software and delete all copies. No refund is owed if you discontinue use because of a change.

20. General

Severability. If any provision is found unenforceable, it will be modified to the minimum extent necessary to make it enforceable, or severed, and the remaining provisions stay in effect.
No Waiver. Our failure to enforce any provision is not a waiver of it. Any waiver must be in writing and signed by an authorized representative of KSTRLWORKS.
Assignment. You may not assign or transfer this Agreement or any License without our prior written consent, and any attempt to do so is void. We may assign this Agreement without restriction.
Entire Agreement. This Agreement, together with our Terms of Service and Privacy Policy, is the entire agreement between you and KSTRLWORKS regarding the Software and supersedes all prior understandings on that subject.
Force Majeure. We are not liable for any failure or delay caused by circumstances beyond our reasonable control.
