Refund policy

14 天内无理由；服务中断按比例补偿 · 运营主体：QuantCard · 联系：hello@quantcard.cc · 更新于 2026-10-12

1. First charge

Email hello@quantcard.cc (or reply to your Paddle receipt) within 14 days of your first payment and you get a full refund, no reason required, no questions asked. Refunds are processed by Paddle as merchant of record and normally appear in 5–10 business days.

2. Later cycles and cancelling

You may cancel a recurring subscription at any time; the current period is not refunded, but your quota stays usable until the period ends and nothing further is charged. For a refund of a period you have barely used, ask — if you have consumed under 10% of the period's cards we will normally refund it.

3. When we are at fault

If the API is unavailable for more than 24 continuous hours, or a billing bug charges you for a cached/deduplicated result, we refund or credit the affected period proportionally, without you having to ask. Cache hits and deduplicated concurrent requests are never billed — if you see a charge that looks wrong, send us the request time and we will reconcile it from the usage log.

4. What is not refundable

Nothing is non-refundable because of "the numbers came back negative". A card is a research output, not a promise of profit; but if you believe a card was produced by a defect (wrong cost model, mislabelled dataset, methodology silently changed), tell us and we will re-run it and refund the unit if we were wrong.

5. Chargebacks

Please contact us before opening a dispute; we refund promptly and would rather give money back than fight a chargeback. Duplicate-charge complaints are always resolved in your favour.
