If you do not agree to these Terms, do not use the Services. If you use the Services on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.
The Services are software-as-a-service (SaaS) platforms designed for aviation parts and maintenance organizations to streamline quality control, documentation, compliance, quoting, and finance workflows. They include, depending on your subscription:

The AvPics mobile application (the "Mobile App") is distributed through the Apple App Store and is subject to these Terms in addition to the App Store's terms.
You must create an account to use the Services. Authentication may be provided through email/password or single sign-on (e.g., Microsoft Entra). You agree to provide accurate, current, and complete information and to keep it updated.
You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to notify us immediately of any unauthorized use of your account.

The pricing published at jassco.net and in your order or written agreement is authoritative and controls in the event of any discrepancy. Plans, seat counts, and prices are subject to change with at least 30 days' notice for renewals.
Subscriptions are billed in advance, monthly or annually depending on the plan, through our payment processor (Stripe) or, where agreed, by invoice on net terms. You authorize us (and our payment processor) to charge your payment method for all applicable fees and taxes. Failed or overdue payments may result in suspension of access (subject to Section 12.4).
You may cancel your subscription at any time. Cancellations take effect at the end of the current billing period. Except where required by law, we do not provide refunds for partial periods or unused services.
Certain features (for example, the in-app compliance assistant, document drafting, and Finance summaries) use third-party large-language-model providers (currently Anthropic) to process the specific inputs you submit and relevant Customer Data in order to generate responses. When you use these features:
The Services are documentation, workflow, and record-keeping tools. They do not perform maintenance, do not make airworthiness determinations, and do not constitute approval, certification, or release-to-service of any aircraft part or article.
The Services and all related technology, including software, designs, and trademarks, are the property of Turbsol Management, LLC. You are granted a limited, non-exclusive, non-transferable license to use the Services in accordance with these Terms.
You and your organization retain all rights, title, and interest in and to all data, photos, documents, inspection records, quotes, and any other content you upload, create, or store using the Services ("Customer Data"). Longeron does not claim ownership of Customer Data under any circumstances.
By using the Services, you grant Longeron a limited, non-exclusive, revocable license to host, store, process, transmit, and display Customer Data solely to provide, maintain, secure, and support the Services (including via the sub-processors described in Section 10). This license terminates when you delete your content or close your account.
Longeron will not:
The Services integrate with third-party systems that you choose to connect (such as AvSight/Salesforce, Smart145, and cloud storage providers). We are not responsible for the availability, functionality, or policies of those services, and your use of them is subject to their own terms. You are responsible for having the right to connect them and for the credentials you provide.
To operate the Services, we use a limited set of sub-processors, including: Supabase (database, authentication, and file storage, backed by AWS), Vercel (application hosting), Stripe (payment processing), Anthropic (AI features), and Microsoft (single sign-on and Microsoft Graph/SharePoint, where used). Our handling of personal data and the current sub-processor list are described in our Privacy Policy, which is incorporated into these Terms by reference.
The Services are provided "as is" and "as available" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that the Services will be uninterrupted, error-free, or secure, or that any output (including AI-assisted output) is accurate or complete.
To the maximum extent permitted by law, Turbsol Management, LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses. To the maximum extent permitted by law, our aggregate liability arising out of or relating to the Services shall not exceed the amounts you paid to us for the Services in the twelve (12) months preceding the event giving rise to the claim.
You agree to indemnify and hold harmless Turbsol Management, LLC and its affiliates from any claims, damages, or expenses arising from your use of the Services or violation of these Terms.
While we implement backup procedures, you are responsible for maintaining your own backups of critical data. We are not liable for any data loss.

Under no circumstances will Longeron withhold access to Customer Data as leverage in any commercial dispute. Customers may always retrieve their data regardless of account standing or payment status.
Longeron is a brand owned and operated by Turbsol Management, LLC, which is the legal entity responsible for the development, operation, and maintenance of the Services. References to "Longeron" in these Terms refer to Turbsol Management, LLC. Longeron is not affiliated with, owned by, or a subsidiary of any customer organization. Customer relationships and integrations do not create any agency, partnership, or joint venture relationship.
Customer Data stored in the Services is logically and operationally separate from Longeron's own operational data. Customer Data is not commingled with Longeron's proprietary data and is not treated as an asset of Turbsol Management, LLC in any financial, legal, or corporate proceeding.
We may suspend or terminate your access to the Services for violations of these Terms or as otherwise permitted. Upon termination, your right to use the Services ceases; however, your right to retrieve Customer Data under Sections 14.1 and 14.4 survives.
These Terms are governed by and construed in accordance with the laws of Florida, United States.
You shall comply with all applicable export control laws and regulations, including International Traffic in Arms Regulations (ITAR), Export Administration Regulations (EAR), and Office of Foreign Assets Control (OFAC) sanctions programs. You are responsible for ensuring that any data you upload and any access you grant comply with such laws.
We reserve the right to modify these Terms at any time. We will notify you of material changes by posting the updated Terms on this page and updating the "Last Updated" date. Your continued use of the Services after changes constitutes acceptance of the new Terms.
