UTXO Business OS
End-User License Agreement.

UTXO Business OS (Business OS · Studio edition · Windows app) is published by UTXO Core Labs, operating under the trade name Huri's, with registered offices in Stuttgart, Germany.

All intellectual property in the software — including but not limited to source code, compiled binaries, installers, icons, brand assets (UTXO Suite mark, UTXO Core Labs marks, Huri's marks), documentation, design tokens, design systems, animations, marketing copy and the contents of this website — is owned by UTXO Core Labs and protected under German and international copyright, trademark and database-rights law.

No part of the software or its assets may be reproduced, distributed, modified, decompiled, sold, sublicensed, embedded into a competing product or used to train machine learning models without prior written permission from UTXO Core Labs. Exceptions explicitly allowed by mandatory law (security research, interoperability, accessibility) remain unaffected.

1. License grant. Subject to your acceptance of this EULA and, where applicable, payment of the subscription fees, UTXO Core Labs grants you a personal, non-exclusive, non-transferable, revocable license to install and use UTXO Business OS on the devices covered by your plan. The license is granted, not sold.
2. Permitted use. You may use the software for lawful purposes inside the entity to which the license is issued. Multi-tenant resale, white-labeling, embedding the software in a competing product or providing the software as a service to third parties is prohibited without a separate written agreement.
3. Restrictions. You may not (a) decompile, disassemble, reverse engineer or attempt to derive source code; (b) remove or alter copyright, trademark or proprietary notices; (c) use the software to train, fine-tune or evaluate machine learning models; (d) circumvent license enforcement; or (e) use the software in safety-critical or life-supporting systems. Mandatory legal exceptions remain unaffected.
4. Local-first & privacy. UTXO Business OS is designed local-first. By default no personal data, files, credentials, transactions or telemetry leave your device. If you enable an optional integration (cloud backup, AI Gateway, email gateway, payment rail), the corresponding third-party terms apply to that flow. UTXO Core Labs publishes a separate Privacy Notice at www.utxosuite.com/legal.
5. Updates. The software may receive signed updates. You may decline non-security updates from Settings; security patches may be required to continue using paid features and may be applied automatically when a critical CVE is published.
6. Subscription & billing. Paid tiers are billed through UTXO Pay on the Stripe rail in USD reference. Prices on the website are converted to your local currency at the live FX rate; the actual charge is processed in USD on your card. Subscriptions renew automatically until cancelled. Refunds are issued pro-rata in accordance with EU consumer law for purchases by consumers within the 14-day withdrawal period.
7. License keys. Each license key is bound to the seat count of your plan. Sharing keys with users outside your organization terminates the license. UTXO Core Labs may verify license validity against the activation endpoint with the minimum personal data required (key, device identifier).
8. Warranty disclaimer. The software is provided "as is" and "as available". To the maximum extent permitted by law, UTXO Core Labs disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement and absence of bugs. No business software is infallible: you remain responsible for adequate backups and operational controls.
9. Limitation of liability. UTXO Core Labs's aggregate liability under this EULA shall not exceed the fees you paid for UTXO Business OS during the most recent twelve (12) months, or €100 if you use the free tier. UTXO Core Labs is not liable for indirect, incidental, consequential, special or punitive damages, or for lost profits, data, business or goodwill. Mandatory liability under product liability law, for fraud, or for death and personal injury caused by negligence is unaffected.
10. Termination. This license terminates automatically if you breach it. You may terminate at any time by uninstalling the software and cancelling the subscription. Termination does not affect accrued rights or obligations.
11. Export & sanctions. You confirm that you are not located in, and will not export the software to, a country subject to EU or US sanctions, and that you are not listed on any restricted-party list.
12. Changes to the EULA. UTXO Core Labs may amend this EULA with at least 30 days' notice for paid users. Continued use after the effective date constitutes acceptance. If you do not accept a change, you may cancel and receive a pro-rata refund of unused prepaid fees.
13. Governing law & jurisdiction. This EULA is governed by the laws of the Federal Republic of Germany, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods. The competent courts of Stuttgart, Germany shall have exclusive jurisdiction, without prejudice to mandatory consumer protection rules in your country of residence.
