Refund Policy

All payments are processed by our reseller, Creem.io, which acts as the Merchant of Record for every transaction. Creem handles billing, tax collection and remittance, and card processing on our behalf. Charges on your bank or card statement will appear under Creem's name, not Lumen Sieve.

You can cancel a paid plan at any time from the Billing page in your dashboard, or by emailing support@lumensieve.com. Cancellation takes effect at the end of your current billing period — you keep full access and your existing quota until then, and you will not be charged again.

Downgrading to a lower tier works the same way: it's scheduled for the start of your next billing cycle, and you keep your current plan and quota until it takes effect.

Because plans are billed in advance and usage-based overage charges reflect API calls already made, refunds are not automatic. We review refund requests case by case and issue them at our discretion for exceptional circumstances — for example, a duplicate charge, a charge after cancellation should have taken effect, or a billing error on our side.

To request a refund, email support@lumensieve.com with your account email and the transaction in question. We aim to respond within 2 business days. Approved refunds are issued back to your original payment method via Creem and typically post within 5–10 business days, depending on your bank or card issuer.

The Free plan requires no payment method and carries nothing to refund. Its 50 lifetime lookup queries are a one-time trial allowance, not a recurring charge.

If you have a billing concern, please contact us before filing a chargeback with your bank — we can typically resolve refund and billing issues directly and faster than a chargeback process. Accounts with an open chargeback may be suspended while it is under review, in line with our Terms of Service.
