Top-up and Refund Policy

Effective date: July 29, 2026 Last updated: August 29, 2026

This Top-up and Refund Policy ("Policy") supplements and forms part of the Modelflare Terms of Service. It applies to prepaid credit top-ups, subscription purchases, renewals, and upgrades purchased from Havenbyte LLC through Modelflare.

1. Scope and Acceptance

By confirming a top-up payment or a subscription purchase, renewal, or upgrade, Customer agrees to this Policy. The top-up provisions apply to top-ups processed on or after July 29, 2026. The 48-hour refund window is a customer-favorable extension that applies to all top-ups otherwise eligible for the self-service refund flow, including top-ups processed before this update. The subscription provisions in Section 6 apply to subscription transactions processed on or after August 8, 2026. Except for this customer-favorable extension of the top-up refund window, earlier transactions remain governed by the other terms in effect when the transaction was processed.

Except where applicable law requires otherwise, this Policy does not create a right to refund consumed Services, promotional credits, third-party charges, taxes, invoice fees, bank fees, or other amounts that cannot be returned.

Except where applicable law requires otherwise, stablecoin top-ups are non-refundable.

2. Refund Window

Customer may request a refund within forty-eight (48) hours after the relevant top-up transaction is processed. The request must be received through the self-service refund entry in the Modelflare console or an official Modelflare support channel within that period. The time we receive the request, rather than the time we finish reviewing it, determines whether the request was submitted on time.

After the forty-eight (48) hour period expires, the unused portion is non-refundable except where applicable law requires otherwise.

3. Refundable Principal and Bonus Credits

Only the unused paid portion of the relevant top-up may be refunded. Promotional, bonus, trial, gift, referral, or other non-purchased credits have no cash value and are not refundable.

The refundable principal is calculated from Customer's available paid credits when we receive the refund request. We first subtract all bonus and other non-purchased credits granted with the relevant top-up from those available credits. If the result is less than zero, it is treated as zero. The refundable principal is the lesser of that result and the amount actually paid for the top-up.

Example: if Customer pays US$20 and receives US$21 in credits, including a US$1 bonus, then uses US$1, the remaining credits are US$20. We first exclude and revoke the US$1 bonus, leaving a refundable principal of US$19.

We determine usage, remaining credits, bonus credits, and refundable principal from our transaction, credit-ledger, promotion, and usage records.

4. Refund Processing Fee

The refund processing fee described in this section is not charged when a top-up is purchased. It applies only when a refund is processed.

Each approved refund is subject to a processing fee equal to five and one-half percent (5.5%) of the refundable principal, with a minimum fee of US$0.80. The percentage fee is calculated before the fee is deducted and is rounded up to the nearest cent. The fee is non-refundable.

The amount returned to the original payment method equals the refundable principal minus the refund processing fee. If the refundable principal is US$0.80 or less, no cash refund will be processed because the minimum fee equals or exceeds the refundable amount, except where applicable law requires otherwise.

In the example above, the refundable principal is US$19. The 5.5% fee is US$1.045 and is rounded up to US$1.05. The amount returned is therefore US$17.95, while the remaining US$20 in credits, consisting of US$19 paid credits and the US$1 bonus, is removed from the account.

5. Refund Method and Account Reconciliation

Eligible refunds are returned only to the original payment method unless applicable law requires another method. Payment-provider, bank, invoice, tax, foreign-exchange, or other third-party amounts that the relevant provider does not return are not part of the refundable principal.

When we process a refund through the self-service refund entry or an approved support flow, we revoke the corresponding refundable paid credits and the related bonus credits, withhold the refund processing fee, and return the remaining amount through the payment provider.

If Stripe or another payment provider confirms a full or partial refund through another channel, or confirms a refund before we could withhold the processing fee or revoke credits, we may deduct from Customer's account the refunded amount, the related bonus or promotional credits, and the applicable refund processing fee. This reconciliation applies even if some or all credits have already been used. Account credits may become negative, and we may suspend the account and its API keys until the resulting refund debt is resolved.

If the payment provider later confirms that a refund failed, was canceled, or was reduced, we may restore the corresponding previously deducted credits based on the verified provider state. Receiving a payment refund does not cancel Customer's obligation to pay for consumed Services, the refund processing fee, or other non-returnable amounts.

6. Subscription Purchases, Renewals, and Upgrades

Except where applicable law requires otherwise, subscription purchases, renewals, and upgrades are final and non-refundable. Customer is not entitled to a full, partial, or prorated refund because subscription quota was unused, expired, only partly used, or no longer needed.

Canceling automatic renewal prevents future renewal charges only. It does not cancel, refund, or prorate the current subscription period. Unused subscription quota cannot be converted to cash or account credits, transferred to another account, or carried beyond the applicable reset or expiration time unless the purchased plan expressly states otherwise.

A plan downgrade is not immediate. If the downgrade option is available, the current plan remains in effect through the current paid period, and the lower plan and its price take effect at the next renewal. Canceling renewal likewise takes effect at the end of the current paid period; no further renewal charge is made.

An enterprise or customized subscription may be governed by a separate written quote, order form, master services agreement, or other written agreement accepted by both parties. If that agreement expressly states different cancellation or refund terms, those written terms control to the extent of the conflict. Otherwise, the non-refundable rules in this Section apply.

If applicable law or a payment provider requires a subscription payment to be reversed, we may revoke the remaining subscription entitlement, terminate or adjust the subscription, and reconcile consumed Services, promotional benefits, account credits, and any resulting amount owed to the extent permitted by law.

7. Review and Abuse Prevention

We review refund requests using account status, payment date, identity consistency, transaction and usage records, payment-provider rules, fraud and abuse risk, sanctions risk, chargeback risk, and applicable law. We may require proof of payment, transaction IDs, identity information, or account ownership evidence.

We may refuse a refund request, suspend an account, or take other necessary measures where the request presents fraud, stolen-payment, money-laundering, sanctions, arbitrage, abuse, identity-mismatch, or other legal or security risk, except where applicable law requires the refund.

8. Changes and Contact

We may update this Policy from time to time. An updated Policy generally applies prospectively from the effective date stated in the updated version, except where applicable law requires otherwise. The 48-hour refund window in Section 2 is an express customer-favorable extension that applies to all otherwise eligible top-ups, including top-ups processed before this update.

To request a refund for an eligible top-up, use the self-service refund entry in the Modelflare console. Subscription purchases are not eligible for that self-service refund flow. For a billing question or a matter that requires review under applicable law, contact us through an in-dashboard support ticket, an official support channel published on our website, or support@modelflare.dev. For an enterprise or customized subscription inquiry, contact business@modelflare.dev.
