Refund and Cancellation Policy
Version 2026-08-18. Effective 2026-08-18. Supersedes the version of 2026-08-17.
This policy covers the three ways you can pay for merkleset datasets: monthly subscriptions (sections 1 to 7), one-time Corpus Snapshot purchases (section 8), and the prepaid wallet (section 9). It is part of the Terms of Service.
Two structural facts shape everything below:
- We sell to businesses and professionals only. This policy is written for a business-to-business sale. It is not a consumer policy, and consumer withdrawal rights are addressed separately in section 10.
- Stripe processes the transaction as merchant of record. We set the substantive position — when you can cancel, what is refundable and what happens to your data. Stripe executes the payment mechanics: it issues your invoice, performs any refund, and administers chargebacks and any statutory refund right that attaches to the transaction itself.
1. Cancelling
1.1 You may cancel at any time. Email contact@merkleset.com from the address on your account, or use whatever cancellation control your plan provides.
1.2 Cancellation takes effect at the end of the period you have already paid for. You keep access and keep receiving releases until then.
1.3 We will confirm your cancellation by email. If you do not get a confirmation within two business days, chase us — do not assume it went through.
1.4 Cancelling stops the next renewal. It does not reverse the current period; see section 2.
2. Refunds
2.1 A started period is not refundable in part. Subscriptions are monthly, releases are delivered continuously through the period, and a partial month cannot be un-delivered. So there is no proportionate refund for the unused remainder of a period you have started.
2.2 A period we failed to deliver is refundable. If a dataset you paid for published no release during a period in which it should have published at its stated cadence, and the cause was on our side, tell us and we will refund that period in full or extend your subscription by the equivalent, whichever you prefer.
2.3 First-period good-faith exception. If you subscribe for the first time and, within 14 days of the start of your first paid period, tell us that the service does not do what our documentation says, we will refund that first period in full. This is a narrow exception, and we mean it as it reads: it covers a genuine failure of the service to match its description, not a change of plan or a budget decision. It applies once per customer, to a first paid period only.
2.4 If we retire a dataset you subscribe to, we refund the unused part of any fee prepaid for it (clause 5.7 of the Terms of Service). That is a deliberate exception to section 2.1, because the failure to deliver is ours.
2.5 Refunds are made through the merchant of record, to the original payment method, in the original currency. Timing depends on your bank.
2.6 Taxes charged on a refunded transaction are handled by the merchant of record as part of the refund.
2.7 We do not refund free or demo access, because nothing was paid for it.
2.8 No refund can exceed what you actually paid. Whatever remedy applies under this policy — a refund, a re-credit, an extension of your subscription, or any combination of them — the total we return for a given item can never exceed the amounts we have actually received from you for that item. Nothing here pays out twice against the same payment, and no remedy leaves you further ahead in money than if the purchase had not happened. This cap applies to all three purchase shapes in this policy: subscriptions, one-time Corpus Snapshot purchases (section 8) and wallet top-ups (section 9). It applies alongside, not instead of, any mandatory right you have under applicable law that cannot be excluded by agreement; where such a right gives you more than this section would, that right prevails. See section 10 for the consumer position and what remains open on it.
3. What happens to data you already received
3.1 Your licence to releases already delivered survives cancellation, permanently. You do not have to delete downloaded releases, embeddings, indexes, fine-tuned models or anything else you built from them. This is set out in clauses 3.1 to 3.4 of the Data License Agreement, and it is deliberate: cancelling should not force you to rebuild a vector database.
3.2 Access ends when the subscription ends. No further downloads, no new releases, and no new signed URLs. Download what you need before your period ends — we are not your archive, and clause 5.4 of the Terms of Service says so plainly.
3.3 The prohibitions in the Data Licence and the Acceptable Use Policy continue to apply to data you keep. In particular, no redistribution, no competing data product and no re-identification.
4. Non-payment
4.1 If a payment fails, the merchant of record will normally retry and notify you.
4.2 If payment remains unmade, or is reversed, more than 14 days after it was due, we may suspend delivery and downloads for the affected datasets after telling you.
4.3 Suspension for non-payment does not revoke your licence to releases already delivered.
4.4 If you settle the amount due, we restore access. If you do not, we may terminate the subscription under clause 12 of the Terms of Service.
4.5 Do not use a chargeback as a cancellation route. If you think a charge is wrong, tell us first at contact@merkleset.com. We would rather fix a billing mistake than defend a dispute.
5. Changing plan
5.1 An upgrade takes effect when we confirm it, and the price difference is charged for the remainder of the period.
5.2 A downgrade takes effect at the start of your next period, so you keep what you paid for.
5.3 Adding a dataset starts a new subscription for that dataset on the same period boundary, unless we agree otherwise.
6. Price changes
6.1 We give at least 30 days' notice of a price change, and it applies from your next period (clause 4.5 of the Terms of Service).
6.2 If you cancel because of a price change, before the new price takes effect, nothing extra is payable.
7. If we terminate
7.1 If we terminate for your material breach, no refund is due.
7.2 If we terminate for any other reason, we refund the unused part of the current period.
7.3 We may end free or demo access at any time, with no refund, because nothing was paid.
8. One-time Corpus Snapshot purchases
8.1 A Corpus Snapshot is a one-time purchase, not a subscription: you buy the latest full published release of one dataset as it stands at the time of purchase, licensed under the Data License Agreement, with a 12-month re-download window for the exact release you bought. Nothing renews and nothing further is delivered.
8.2 Delivery is immediate on download. The first time you download the purchased release you have received, in full, the thing we sold. There is no delivery period, no instalments, and nothing left outstanding on our side except keeping the re-download window open.
8.3 Before your first download, we will refund a snapshot purchase in full on request within 14 days of purchase. Nothing has been delivered yet, so nothing has to be un-delivered.
8.4 After your first download, the purchase is not refundable. A delivered release cannot be returned, and your licence to it is perpetual (clauses 3.1 to 3.4 of the Data License Agreement). One exception, mirroring section 2.3: if within 14 days of purchase you tell us that the purchased release does not do what our documentation says, we will refund in full. The same narrowness applies — a genuine failure to match the description, not a change of plan.
8.5 If the re-download window fails on our side — the purchased release stops being available for re-download within its 12 months — we will restore access, or, if we cannot, refund the purchase in full. Losing our copy is our failure, not yours.
9. The prepaid wallet
9.1 You may top up a prepaid wallet balance and pay for downloads from it. A download is debited by corpus size at the rate stated at the time of the debit. The first download of a release debits your balance; re-downloading the same release is not charged again.
9.2 An unused top-up is refundable. We refund a top-up in full on request within 14 days of that top-up, provided no download debit has occurred since it — the balance is still just money, and nothing has been delivered against it.
9.3 Once any debit has occurred since a top-up, the position mirrors the rest of this policy on delivered digital content. The debited amounts paid for releases that were delivered in full at the moment of download and are not refundable. The remaining balance is then no longer refundable as of right under section 9.2; we may still refund a remaining balance on request at our discretion, but this policy does not promise it. This is our intended commercial position, stated as such — see section 10.4 for what remains open on it.
9.4 A debit for a download that failed on our side is re-credited. Tell us at contact@merkleset.com; we would rather re-credit than argue.
9.5 Credits do not expire, unless an expiry was stated to you at the time of the top-up.
9.6 Balances are non-transferable. A wallet balance belongs to the account that topped it up. It cannot be moved to another account, pooled across accounts, or redeemed for cash except as sections 9.2 and 9.7 provide.
9.7 If we retire the wallet, or terminate your account other than for your material breach, we refund the unused balance in full. A prepaid balance is money held against future delivery; if we stop delivering, it comes back.
9.8 The cap in section 2.8 applies to the wallet too. A refund of a balance is limited to the amount you actually paid in and have not yet spent: amounts already debited for downloads you received are not refunded a second time, and the total of every refund and re-credit relating to a top-up can never exceed what that top-up cost you.
10. Consumer withdrawal rights — the assumption behind this policy
10.1 This policy assumes business-to-business sales only. Accepting a customer who is buying as a consumer changes the legal position, because Spanish and EU consumer law gives a consumer a 14-day right of withdrawal for a distance contract.
10.2 For digital content and digital services there is a carve-out from that right, but it is conditional: it applies only where supply has begun and the consumer expressly consented to supply beginning before the withdrawal period ended and acknowledged losing the right of withdrawal. Without both, the right survives and a full refund can be demanded.
10.3 So if merkleset ever sells to a non-business customer, the order and payment process must capture that express consent and that acknowledgement — for a subscription, a snapshot purchase and a wallet top-up alike — and this policy needs a consumer section written for that regime.
10.4 [COUNSEL] Section 10 states an assumption, not settled advice: this policy is drafted B2B-only under Spanish law (in particular Real Decreto Legislativo 1/2007), and the consumer analysis is unresolved for each purchase shape, differently for each. For a subscription, the withdrawal-acknowledgement mechanics and who must capture them. For a one-time snapshot, whether supply "begins" at purchase or at first download, and what the pre-download refund in section 8.3 does or does not concede. For the wallet, whether a top-up is itself a supply of digital content or a prepayment for future supply, whether a debit is the moment supply begins — and for how much of the balance — and whether the refund rule in section 9.2 is a sufficient answer to a withdrawal demand. The same reservation attaches to the payment cap in section 2.8: it is our commercial position, expressly subordinated to mandatory law, and whether it holds against every non-excludable consumer remedy is for counsel to confirm rather than for this policy to assert. None of this is asserted as legal certainty; it is the commercial position we intend, and it requires attorney review before any non-business sale.
