Terms of Service

These terms govern your use of the DualQuant strategy verification service. They are written to be read, so they are shorter than they could be and plainer than they need to be.

Version 1 · In effect from 3 November 2026 · Private preview

1. Who provides the service

The service is provided by DualQuant ("we", "us"), established in the Czech Republic and operating from the European Union. You can reach us at support@dualquant.ai, which is the address for every kind of question, including legal ones.

DualQuant is not a broker, an exchange, an investment adviser, a fund or an asset manager. We hold no customer money, place no orders and have no position in any instrument a verdict concerns.

2. What the service does

You describe a trading strategy. We agree an exact plan with you, fix it, run it against market data, and return a report stating what was checked and what was found. The method is described in full in the white paper, which forms part of your understanding of what you are buying.

A report carries one of four verdicts -- CHECKED, REJECTED, BLOCKED or UNCHECKABLE -- together with the result of each check, the comparison against a risk-matched passive benchmark, and an explicit list of what the report does not claim.

3. Accounts and API keys

Access requires an account and an API key. The key is a bearer credential: anyone presenting it is treated as you. Keep it secret, do not put it in a public repository or a client-side application, and tell us immediately at support@dualquant.ai if it may have been exposed, so we can revoke and replace it.

A session handle returned during a verification is also bearer-equivalent for that session. It should be handled with the same care as the key and should not be written to logs.

You are responsible for activity performed with your credentials, including activity by an automated agent you operate. If you let an agent drive the service, the attempts it makes are your attempts.

4. Attempts, fees and roll-over

An attempt is one complete verification of one pre-registered plan against a dataset, or one complete company research view, in either case over the API. Asking for the same company again on the same UTC day uses no further attempt. The subscription is $20 per month for 20 attempts, with additional blocks available at the same rate.

Unused attempts roll over for as long as the subscription is active. Your balance is the total of every attempt ever granted to you, less every attempt ever charged. We do not reset it monthly, because an allowance that resets is an allowance that expires, which is not what was paid for.

The following are never charged:

• A pre-flight refusal, where we tell you before reading any data that the rules are not supported or the dataset is not available.
• A failure caused by us -- a platform error, an interrupted run, or an internal fault.
• Questions or clarifications about a verdict you already received.

A verdict of REJECTED, BLOCKED or UNCHECKABLE is charged. Each of those is a completed verification that consumed the same work as a pass, and a finding you were entitled to receive.

You may cancel at any time. Attempts already in your balance remain yours and stay usable; we do not claw back what you have paid for.

If you are a consumer in the EU

You have a statutory right to withdraw from a distance contract within 14 days, without giving a reason. Because this is a digital service we begin performing immediately, that right ends once performance has started with your express consent -- so when you subscribe we will ask you to confirm that you want to start straight away and that you understand you lose the withdrawal right by doing so. If you would rather keep the right, wait out the 14 days before running anything.

Where the withdrawal right still applies, we refund you in full within 14 days. Outside it, we do not refund subscription payments already taken, because the attempts they bought do not expire and remain usable. Nothing here limits your rights under Czech consumer law or Directive 2011/83/EU.

If we cannot resolve a complaint between us, a consumer may take it to the Czech Trade Inspection Authority (Ceska obchodni inspekce, coi.cz), which is the competent out-of-court dispute resolution body.

Tax

Prices are stated in US dollars. Value added tax is charged where it is due, at the rate of the customer's own country for consumers in the EU, and under the reverse charge for EU businesses that give us a valid VAT number. A consumer will be shown the final price including VAT before paying.

Buying more attempts increases your balance and does not change the standard a result must meet. The count of distinct plans you have tested against a dataset is recorded and raises the statistical hurdle any single variation must clear. This is a deliberate and permanent feature, not a limitation we intend to relax.

5. What we undertake

These are commitments, not aspirations. They constrain how the service is built, and we would have to change the architecture to break them.

• We never publish a rank or a leaderboard.
• We never suggest a parameter, indicator or fix for your strategy. Doing so would make us a co-author of what we audit.
• We never issue a weak pass. A check either reached its answer or reports honestly that it did not.
• We never fund, allocate to, or take a position in a strategy on the basis of a verification, and we never trade against you.
• We never state a check ran when it did not. Checks that are not built are named in every verdict as not built.
• We charge a flat fee and have no interest in which direction any verdict goes.

6. Your strategies remain yours

You keep all rights in anything you submit: the description, the rules, the condition tree, and any data you bring. Nothing you send becomes ours.

You grant us only the permission needed to do the job you asked for: to store your submission, run it against market data, produce your report, and retain the records described in the privacy notice so a verdict stays replayable and the attempt count stays correct.

We do not publish your strategy, rank it, show it to another customer, use it to trade, or use it to train a model. You submit rules in a closed grammar rather than code, and we do not execute code on your behalf.

We may describe aggregate, non-identifying facts about the service -- for example how many verifications ran, or how often a given rung fails -- in a form that identifies neither you nor any strategy.

7. A verdict is not advice

This section matters more than its length suggests. A report from this service is a statement about a historical record. It is not investment advice, not a recommendation to trade or not trade anything, not a forecast, and not an assurance that a strategy will continue to work or ever worked outside the period tested.

A verdict of CHECKED means the record was real and executable on the data it names. It is not an endorsement of the strategy, and it is deliberately not called VERIFIED for that reason.

Trading involves risk of loss, including total loss. Every decision to deploy capital is yours alone, and you should take independent professional advice before doing so. We provide no such advice and are not regulated to.

8. Acceptable use

You agree not to:

• share, resell or sublicense your API key, or provide access to the service as though it were your own;
• misrepresent a report -- for example by presenting a verdict as an endorsement, quoting a result without its stated scope and caveats, altering a report, or implying a check ran that the report says did not;
• use multiple accounts to reduce your recorded attempt count, which is an attempt to defeat the statistical correction rather than a billing question;
• submit data you do not have the right to give us, including market data whose licence forbids it;
• attempt to disrupt the service, circumvent its limits, or access another customer's sessions, reports or records.

9. Availability and preview status

The service is in private preview. It is offered as it stands, without a service level commitment, and may be interrupted for maintenance or change without notice. Features described as planned or not built may change or may never be built.

We will not silently remove a check and continue reporting as though it ran. If a check stops running, verdicts will say so.

10. Liability

We provide the service with reasonable care and skill. We do not warrant that it will be uninterrupted or error-free, nor that a verification will detect every possible flaw in a strategy or a dataset.

To the extent the law allows, we are not liable for trading losses, lost profits, lost opportunity, or any indirect or consequential loss arising from your use of the service or from any decision you take after reading a report. Our total liability to you for any claim is limited to the fees you paid us in the twelve months before it arose.

Nothing in these terms excludes liability that cannot lawfully be excluded, including liability for fraud or for death or personal injury caused by negligence.

11. Ending the agreement

You may stop using the service and close your account at any time by writing to support@dualquant.ai.

We may suspend or end your access if you breach these terms, if your use threatens the integrity of the service or another customer's data, or if we are required to. Where it is reasonable to do so, we will tell you why and give you a chance to put it right.

Reports already issued to you remain yours. What happens to the records we hold is set out in the privacy notice.

12. Changes to these terms

We may update these terms. The version and date at the top of this page always identify the current text. Material changes will be notified to active account holders by email before they take effect, and continuing to use the service after that date means you accept them. If you do not, you may close your account.

13. Governing law

These terms, and any dispute arising out of or in connection with them, are governed by the law of the Czech Republic, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. The courts of the Czech Republic have jurisdiction.

If you are a consumer, this does not deprive you of the protection of the mandatory law of the country where you live, and you may bring proceedings there. The service is operated from the European Union and your data is stored on servers within it; the privacy notice sets out the one processing step that happens outside it, and how to avoid it.
