Terms of Service

These Terms of Service govern your access to and use of Lefine, including task creation, solver matching, authentication flows, payment flows, and digital result delivery.

By using the service, you agree to these Terms.

1. Description of the Service

Lefine is a digital product that helps users submit tasks, route them through solver workflows, manage payment and access steps, and receive digital results or delivery artifacts.

All product outputs are delivered digitally. No physical goods are provided through the service.

2. Accounts and Access

Some features may require a wallet connection, passkey, email-based communication, or another supported authentication method.

You are responsible for maintaining control over the devices, credentials, or accounts you use to access the service.

3. Orders, Pricing, and Billing

Task pricing, execution windows, and payment requirements may vary based on solver availability, task complexity, and delivery conditions.

We may use payment providers or payment infrastructure partners to process transactions, generate payment links, or verify settlement.

You are responsible for reviewing the applicable price and payment requirements before completing a transaction.

4. Digital Delivery and Fulfillment

Digital access, task execution, and result delivery may begin shortly after payment or other required confirmation steps are completed.

Because the product is digital in nature, fulfillment state may affect refund eligibility or cancellation rights where permitted by applicable law.

5. User Conduct

You may not misuse the service, interfere with its operation, attempt unauthorized access, submit unlawful content, or use the platform in violation of applicable law.

We may suspend, restrict, or terminate access if we reasonably believe the service is being abused or used in a harmful way.

6. No Guarantees

The service is provided on an as available basis. We do not guarantee uninterrupted availability, specific solver outcomes, or specific economic results.

Execution estimates, rankings, or solver selections shown in the product may change as the task progresses.

7. Limitation of Liability

To the maximum extent permitted by law, Lefine is not liable for indirect, incidental, special, consequential, or punitive damages arising from the use of the service.

Nothing in these Terms excludes liability that cannot be excluded under applicable law.

8. Intellectual Property

The website, interface, product content, and related materials remain the property of Lefine or its licensors unless otherwise stated.

You may not reproduce, redistribute, reverse engineer, or republish protected materials except as expressly permitted by law or written permission.

9. Changes to These Terms

We may update these Terms from time to time. Continued use of the service after updated Terms become effective constitutes acceptance of the revised Terms.
