Clear terms for a prepaid service.

1. Agreement and operator

These terms govern your use of FeynmanLM and its managed services. The service is operated by Aurify Technologies Ltd. By using the service, you agree to these terms and the Privacy Policy. If you do not agree, do not use the service.

2. Your account

Sign in with Apple is required for managed services. You are responsible for access to your Apple account and for activity performed through your FeynmanLM session. Do not use the service in a way that violates law, infringes rights, disrupts the service, or attempts to bypass metering, authentication, or security controls.

3. AI credits and usage

• Purchased credits are a prepayment for future managed AI and hosted-MCP usage; they are not cash, stored-value currency, or transferable.
• Credits do not expire. The displayed balance is maintained in FeynmanLM's server-side billing ledger.
• Usage is deducted at the displayed provider cost plus FeynmanLM's stated margin. A final streamed request can slightly exceed the remaining balance because its exact cost is known only when the response finishes.
• When the balance is empty or negative, managed calls stop until you add credit.
• Promotional or starter credits have no cash value and are not refundable.

4. Purchases, receipts, and tax

Stripe processes payments and stores payment details. After a successful purchase, Stripe provides a receipt and paid invoice through email and your billing history. Prices are shown in US dollars. Applicable tax may be added where legally required and is never added to your spendable credit balance.

5. Optional auto top-up

Auto top-up is off by default. If you enable it, the Checkout confirmation states the refill amount and balance threshold before you save a payment method. Each time your balance reaches that threshold, the selected credit amount plus applicable tax is charged; only the selected credit amount is added as prepaid credit. You can disable auto top-up at any time in Settings; disabling it does not reverse a refill already completed.

6. Refunds and disputes

You may request a refund of unused purchased credit by emailing [email protected]. Consumed usage and promotional credits are not refundable. Approved refunds return the unused purchased amount to the original payment method and remove the corresponding credit from your balance. Bank processing time is controlled by Stripe and your payment provider.

An open payment dispute temporarily freezes managed billing while Stripe reviews it. A lost dispute removes the corresponding purchased credit. These rules do not limit any mandatory consumer rights that apply to you.

7. AI output and service availability

AI output can be inaccurate and should not be treated as professional advice. You are responsible for reviewing output and for deciding how to use it. We may change models, prices, or service features, but completed purchases keep their dollar-denominated credit value. We may suspend access to protect users, investigate fraud or disputes, comply with law, or maintain service integrity.

8. Intellectual property

You retain rights in content you add. You grant the limited permissions needed to process that content when you request a feature. FeynmanLM, its software, design, and service infrastructure remain owned by their respective rights holders.

9. Changes and contact

We may update these terms for future use of the service. Material changes will be identified by a new effective date and, where appropriate, an in-app notice. Questions, refund requests, and billing issues can be sent to [email protected] or through the support page.
