End-User License Agreement
Last updated: July 19, 2026 · This Agreement is between you ("you") and Zapit Technologies ("Zapit Technologies", "we", "us"), a company registered in Texas, USA, the maker of netshell (the "Software").
Please read this Agreement carefully. By downloading, installing, activating, or using the Software, you agree to it. If you do not agree, do not install or use the Software. You represent that you are at least 18 years old and legally able to enter this Agreement. If you use the Software on behalf of a company or other organization, you represent that you have authority to bind that organization, and "you" means both you and that organization, which are jointly responsible under this Agreement. This Agreement governs the Software; your use of our website and your purchase are also subject to our Terms of Sale & Use, and our data practices are described in our Privacy Policy.
1. License granted
When you buy a license, we grant you a personal, non-exclusive, non-transferable license, revocable only as set out in Section 15 (Term and termination), to install and use one copy of the Software on one device that you own or control. The license is one-time and perpetual for the version line you purchased — there is no recurring fee and it does not expire on its own. A valid license is required to use the Software; there is no free trial edition. You may move the license to a different device by deactivating it on the first.
2. What you may not do
- Sell, rent, lease, lend, sublicense, distribute, or otherwise transfer the Software or your license key, except as expressly permitted here or where mandatory local law allows resale of a perpetual license.
- Share one license key across more devices than your license permits, or circumvent the license activation or edition controls.
- Reverse-engineer, decompile, disassemble, or attempt to derive the source code of the Software, except to the limited extent this restriction is prohibited by applicable law.
- Modify, adapt, or create derivative works of the Software, except for configuration and use of documented extension points.
- Remove, obscure, or alter any copyright, trademark, license, or other proprietary notices.
- Use the Software to provide a commercial service to third parties (for example a service-bureau, hosting, or managed-service offering), other than use by your own internal staff, unless we agree in writing.
- Use the Software to access systems you are not authorized to access, or to break any law.
3. Ownership
The Software is licensed, not sold. We and our licensors own the Software and all intellectual-property rights in it, and it is protected by copyright and other laws. You receive only the license expressly granted here and obtain no title to the Software or any copyrights in it. You own your own data, your device configurations, and anything you produce using the Software.
4. Third-party and open-source components
The Software is built on and includes third-party and open-source components, including the open-source Tabby terminal (MIT license) and other libraries, each provided under its own license, which continues to apply to that component. Acknowledgements and applicable notices are provided within the Software (for example, in an "About" or "Licenses" screen). Nothing in this Agreement limits your rights under those open-source licenses with respect to those components. The warranty disclaimers and liability limitations in this Agreement also apply, to the maximum extent permitted by law, for the benefit of the authors and licensors of those components, who are intended third-party beneficiaries of those provisions.
5. Your responsibility for what you run
The Software is a tool for connecting to and operating network and computer equipment. Any command that runs against your devices is run by you, or with your explicit approval. You are solely responsible for the commands you approve and run, for the configuration and state of your equipment, and for maintaining appropriate backups, change controls, and authorisation to access and change those systems. In the current read-only edition, the Software's AI features do not run changes on your devices at all — they investigate with read-only commands and, where a change may be needed, present the exact commands for you to review and run yourself. The AI can be wrong, incomplete, or misleading; its output is a suggestion, not professional advice, and you must independently verify anything before you rely on or run it. You accept the entire risk of operating your own equipment.
6. High-risk and critical uses
The Software is a general-purpose administration tool. It is not designed, tested, or intended for use in any environment requiring fail-safe performance, or where failure or error could lead to death, personal injury, or severe physical, environmental, or infrastructure damage (including life-support, emergency, industrial-control, or safety systems). If you use the Software in such an environment you do so at your own risk and are solely responsible for appropriate safeguards.
7. AI features and your own provider key
The Software's AI features work with an AI provider account that you supply — you bring your own key (for example Anthropic, OpenAI, Azure OpenAI, or Google). When you use those features, relevant session data is sent directly from your machine to the AI provider you chose, under that provider's terms and privacy policy — we are not a party to that relationship, we do not sit in the middle of it, and we are not responsible for how your chosen provider handles your data or for your usage costs with them. Before anything is sent, the Software is designed to strip credentials and other sensitive values (the "data wall") on a best-effort basis; this reduces but does not guarantee the removal of every secret, and is not a warranty that no sensitive data will ever be transmitted. You are responsible for choosing a provider you trust and reviewing that provider's terms. See our Privacy Policy.
8. Your API key and credentials
Your AI provider key and your device credentials are stored on your machine using your operating system's secure credential store, not in a plain configuration file, and are not sent to us. You are responsible for keeping your keys and credentials secure.
9. License activation and validation
Activating a paid license contacts our licensing provider, Lemon Squeezy, over an encrypted connection to verify your key and tie it to your device. This sends only your license key, an activation/instance identifier, and your device's name (hostname). It does not send your terminal contents, credentials, or device configurations. After activation the Software runs offline and re-checks the license periodically when you are online; a network outage will not lock you out of work you have already licensed. Your license permits activation on one device at a time; deactivate it to move to another device.
10. Editions, updates, and changes to the Software
The Software is currently offered as a read-only edition. A write-enabled edition, additional features, or additional device tiers may be offered separately in the future. Updates and fixes within the version line you purchased are included with your license; a future major version may be offered as a separate purchase. We may add, change, or remove features over time. You choose when to install any update.
11. Feedback
If you send us feedback, suggestions, or bug reports, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them for any purpose without obligation or compensation to you.
12. Disclaimer of warranties
The Software is provided "AS IS" and "AS AVAILABLE", without warranty of any kind, whether express, implied, or statutory, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the Software will be error-free, uninterrupted, secure, or free of harmful components, that it will meet your requirements, or that its AI output or any command it suggests will be correct or safe. You bear the entire risk as to the quality and performance of the Software. No statement, whether on our website, in marketing, or from any person, creates any warranty beyond this Agreement. Some jurisdictions do not allow the exclusion of implied warranties or limits on how long an implied warranty lasts, so the above may not fully apply to you; in that case any implied warranty is limited to the minimum scope and shortest duration permitted by law.
13. Limitation of liability
To the maximum extent permitted by law, in no event will Zapit Technologies or anyone involved in creating, producing, or delivering the Software be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, business, or goodwill, or for any damage to, misconfiguration of, or downtime of any equipment, network, or system, arising out of or relating to the Software or this Agreement, even if advised of the possibility and even if a remedy fails of its essential purpose. To the maximum extent permitted by law, our total aggregate liability for all claims relating to the Software will not exceed the amount you actually paid for your license. Nothing in this Agreement limits liability for fraud, for gross negligence or wilful misconduct, or for death or personal injury caused by our negligence, where such limitation is not permitted by law. Some jurisdictions do not allow certain of these limitations, so parts of this section may not apply to you.
14. Indemnification
To the maximum extent permitted by law, you will defend, indemnify, and hold harmless Zapit Technologies and its officers, employees, and suppliers from and against any third-party claim, demand, loss, liability, damage, cost, or expense (including reasonable legal fees) arising out of or relating to: (a) your use of the Software; (b) any command you approve or run and any effect it has on any equipment, network, or system; (c) your violation of this Agreement or of any law; or (d) your access to or use of any system you were not authorized to access. We will notify you of any such claim and may, at our option, participate in the defense with counsel of our choosing.
15. Term and termination
This Agreement takes effect when you first install or use the Software and continues until terminated. Your license terminates automatically if you materially breach this Agreement. On termination you must stop using and remove all copies of the Software. Sections 3, 4, 5, 6, 7, 11, 12, 13, 14, 16, 17, 18, and 20 survive termination.
16. Export control
The Software is subject to the export-control laws of the United States and other jurisdictions. You may not use, export, or re-export the Software except in compliance with those laws, and you represent that you are not located in, and will not use the Software in, any country or by any person or entity subject to applicable U.S. embargoes or restricted-party lists.
17. U.S. Government end users
The Software is "commercial computer software" and "commercial computer software documentation" as those terms are used in 48 C.F.R. 12.212 and 227.7202. If acquired by or on behalf of the U.S. Government, it is provided with only those rights granted to all other end users under this Agreement.
18. Dispute resolution
Before filing any claim, you agree to first contact support@zapittech.com and try to resolve the dispute informally for 30 days. Either party may still bring an individual claim in small-claims court. To the maximum extent permitted by law, any dispute will be brought only in an individual capacity and not as part of any class or representative action. Nothing in this section waives any right that cannot be waived under the law where you live.
19. Governing law
This Agreement is governed by the laws of the State of Texas, United States, without regard to its conflict-of-laws rules. Subject to Section 18, the state and federal courts located in Texas will have exclusive jurisdiction over any dispute, and you consent to that jurisdiction — without affecting any mandatory rights you have under the law where you live.
20. General
This Agreement, together with our Terms of Sale & Use and Privacy Policy, is the entire agreement between you and us regarding the Software. If there is a conflict, the following order controls, highest first: (1) this Agreement, for the Software; (2) the Terms of Sale & Use, for your purchase and the website; (3) the Zapit Technologies company Terms and Privacy Policy, for company-wide matters. If any provision is unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign this Agreement; we may assign it in connection with a merger, acquisition, or sale of assets. We are not liable for any delay or failure caused by events beyond our reasonable control, including outages of third-party services such as our licensing provider. A breach of Section 2 or 3 may cause irreparable harm for which money damages are inadequate, and we may seek injunctive relief in addition to other remedies. Any claim relating to the Software must be brought within one year after it arises, except where a longer period is required by law. Notices to you may be given by email or by posting on the website; notices to us go to support@zapittech.com. We may update this Agreement for future versions or purchases; the version you accepted at install continues to govern that install, and material changes will be posted here with a new "last updated" date.
