1.Acceptance & License Grant

This End User License Agreement (“Agreement”) is a binding agreement between you (the “User,” “you”) and SlabOS LLC (“SlabOS,” “we,” “us”). By installing, accessing, connecting an account to, or otherwise using the SlabOS application and its features (the “Software”), you agree to this Agreement. If you do not agree, do not use the Software.

Subject to your compliance with this Agreement, SlabOS grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Software for your internal business purposes during the period you are an authorized user.

2.The Software

SlabOS is a multi-tenant SaaS platform for countertop fabrication shops, providing quoting, scheduling, job management, slab inventory, a crew mobile app, a customer portal, AI assistance, reporting, and optional integrations with third-party services, including the QuickBooks® Online accounting platform operated by Intuit Inc. (“Intuit”).

3.License Restrictions

You will not, and will not permit any third party to:

• Copy, modify, translate, or create derivative works of the Software;
• Reverse engineer, decompile, disassemble, or attempt to derive source code, except to the extent this restriction is prohibited by applicable law;
• Rent, lease, lend, sell, sublicense, distribute, or make the Software available to any third party except as expressly permitted;
• Use automated scraping or systematic extraction (other than authorized exports) without written permission;
• Probe, scan, or test the Software for vulnerabilities except under a written responsible-disclosure authorization;
• Remove or obscure any proprietary notices; or
• Use the Software in violation of applicable law, export-control regulations, or third-party rights.

4.Accounts & Eligibility

You must be at least 18 years old and have authority to bind the business on whose behalf you use the Software. You are responsible for the accuracy of registration information, the security of your credentials, and all activity under your account. Notify us at security@slabos.org of any suspected unauthorized access.

5.QuickBooks® Online Integration

The Software offers an optional integration with QuickBooks Online. The integration is enabled only if you choose to connect it and authorize access through Intuit’s OAuth flow.

5.1 Data accessed. With your authorization, SlabOS accesses your QuickBooks Online company data solely as needed to provide the features you enable — for example, customers/accounts, invoices, estimates, items, payments, and related accounting records — in order to create and synchronize invoices and quotes, reflect payment status, and surface Intuit-hosted payment links within SlabOS.

5.2 Use of data. SlabOS uses QuickBooks data only to provide and support the integration you requested. SlabOS does not sell QuickBooks data, and does not use it for advertising or for any purpose unrelated to delivering the Service to you.

5.3 Disconnect. You may disconnect the integration at any time from within SlabOS, or from your Intuit account at Intuit’s My Apps. Upon disconnect, SlabOS stops accessing your QuickBooks Online company and revokes/retires the associated access and refresh tokens.

5.4 Retention & deletion. Access and refresh tokens are stored securely and are deleted or invalidated when you disconnect or when your account is closed. Accounting records already written to your QuickBooks Online company remain in your QuickBooks account under your control. You may request deletion of QuickBooks-derived data held by SlabOS by emailing privacy@slabos.org.

5.5 Security. SlabOS transmits data over encrypted connections and stores integration credentials using industry-standard safeguards. See our Security Overview.

5.6 Intuit relationship. “Intuit,” “QuickBooks,” and “QuickBooks Online” are trademarks of Intuit Inc. SlabOS is an independent third-party application. SlabOS is not endorsed by, sponsored by, or affiliated with Intuit, and Intuit is not responsible for the Software. Your use of QuickBooks Online is also governed by your separate agreement with Intuit.

6.Data, Privacy & Security

Our collection and handling of your information is described in the Privacy Policy, and — for paying customers — the Data Processing Addendum. You retain ownership of the business data you submit to the Software and grant SlabOS a limited license to host, process, and transmit it solely to provide the Service to you.

7.Intellectual Property

SlabOS owns all right, title, and interest in the Software, including its brand, trademarks, code, design, models, and documentation. No rights are granted except the limited license expressly stated in this Agreement. Trademarks of third parties (including Intuit) are the property of their respective owners.

8.Third-Party Services

The Software connects with third-party services, including Intuit/QuickBooks (accounting), and may include mapping, messaging, email, AI, and payment providers. Your use of those services is subject to the respective provider’s terms, and SlabOS is not responsible for their availability, content, or acts.

9.Disclaimers

THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE.” SLABOS DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. SLABOS DOES NOT WARRANT THAT THE QUICKBOOKS INTEGRATION WILL BE UNINTERRUPTED OR ERROR-FREE, AS IT DEPENDS ON SERVICES OPERATED BY INTUIT. AI-GENERATED OUTPUTS ARE BEST-EFFORT AND MAY BE INCORRECT; USERS MUST VERIFY OUTPUTS — INCLUDING ANY ACCOUNTING OR TAX DATA — BEFORE RELYING ON THEM. PAYING CUSTOMERS RECEIVE ADDITIONAL WARRANTIES UNDER THE MSA AND SLA.

10.Limitation of Liability

For free and trial users, SlabOS’s aggregate liability is limited to US $100. For paying customers, see the Limitation of Liability provisions in the MSA. In no event will SlabOS be liable for indirect, consequential, special, or punitive damages, or for loss of data or profits arising from your use of the Software or any third-party integration.

11.Term & Termination

This Agreement applies for as long as you use the Software. You may stop using the Software and disconnect any integration at any time. SlabOS may suspend or terminate your license for breach of this Agreement, with or without notice depending on severity. Upon termination, the license granted here ends and you must cease using the Software. Sections that by their nature should survive (including Intellectual Property, Disclaimers, Limitation of Liability, and Governing Law) survive termination.

12.Updates & Changes

SlabOS may update the Software and this Agreement from time to time. Material changes will be communicated by email (where you have an account) or by in-app notice. Continued use after the effective date constitutes acceptance.

13.Governing Law & Disputes

This Agreement is governed by the laws of the State of Illinois, USA. Disputes will be resolved by binding arbitration in Chicago, Illinois under the AAA Commercial Arbitration Rules, except that either party may seek injunctive relief in any court of competent jurisdiction.
