Terms of service

1. Who provides the service

The service is provided by Nicolae Filip Stanciu, trading as “Strateva”, an independent professional working on quantitative research validation.

The full identifying details — tax number, registered address and, where applicable, registry data — do not yet exist: the provider has not completed registration. Until they do, these terms do not enter into force and no engagement can be concluded through this website. Once registration is complete, those details are stated in writing in the proposal for each engagement and on any invoice issued.

The formal contact channel is stan@strateva.ai. The LinkedIn, GitHub, Substack and Malt profiles are public profiles, never a contractual channel.

2. What the service is

Strateva independently validates systematic strategies: it reproduces the result the client declares, on frozen material, examines its fragility, and issues a documented outcome before the client decides whether to move the strategy to shadow trading.

It is a supply of services with a digital deliverable. It is not the sale of pre-existing digital content, it is not investment advice, it is not portfolio management, and it is not a recommendation to allocate capital.

3. Accepted markets

Strategies on cash equities and ETFs, spot crypto and spot FX are accepted.

Strategies whose main exposure depends on derivatives are outside scope: options, futures, perpetuals, CFDs, leveraged tokens and structured products. The reason is technical rather than commercial: those strategies live or die by mechanics a return series does not contain — funding, margin, roll, exercise — and validating them without modelling those would produce a confident-looking figure that means nothing.

4. What the client may send

Code, Pine Script, trade lists and written systematic rules are accepted for assessment, including material produced with AI assistance.

Being accepted for assessment is not the same as being compatible. Compatibility is established by the check described in the next section.

5. Compatibility check

Before any financial commitment exists, the client sends a compatibility request and Strateva reviews the material.

Strateva replies within 48 business hours, stating whether the material can be turned into a reproducible specification within the current scope.

If the material is not compatible with the engine or with the current scope, no proposal is issued and nothing is charged. This check is a human review, not an automated process.

6. Validation Scope

If the material is compatible, Strateva drafts a Validation Scope: one document fixing the claim under test, the asset, the timeframe, the period, the cost assumptions, the benchmark and what would count as a failure.

The Validation Scope is the specific subject matter of each engagement. Every later result is valid only inside it.

One validation equals one strategy version, one asset and one timeframe. A change to the rules is a new version; an additional asset or timeframe is an additional validation.

7. When the contract is formed

Neither this website nor submitting the compatibility form is a binding offer, and neither creates a contractual relationship.

The contract is formed when, in writing, the client accepts the Validation Scope, accepts the price and delivery date stated in the proposal, and payment is confirmed on the agreed terms.

Each engagement is made up of: the particular conditions agreed in writing for it, the confirmed Validation Scope, the confirmed price and deadline, and these general terms.

8. Price, taxes and invoicing

Published prices are those of the packages current at the time of the proposal. The price applying to an engagement is the one in its proposal, not one published later.

Prices are stated exclusive of tax. Applicable indirect taxes are added on the invoice according to the rules in force at the provider’s place of establishment and the client’s status.

The specific tax regime and the moment an invoice is issued will be determined once the provider completes registration, and will be stated in the proposal before any payment.

9. How and when payment is made

Payment is confirmed before work begins. That is the only payment rule settled today.

The specific payment method is stated in writing in the proposal. This website has no payment gateway and no checkout: nothing can be bought or paid for by pressing a button here, and no card details or credentials are requested anywhere on the site.

For the Research and Portfolio packages, any agreed split of the payment is stated expressly in the proposal.

10. When work starts

Work starts when three conditions hold: the Validation Scope is accepted, the material is complete and frozen, and payment is confirmed on the agreed terms.

Before they hold, nothing runs and none of the client’s allowance is consumed.

11. Delivery times

A compatibility request is answered within 48 business hours.

The report delivery date is confirmed in writing in the proposal, per engagement, before the client accepts and before any payment. No fixed per-package deadline is published, because there is not yet enough measurement to support one, and publishing a figure without it would be a commitment the provider cannot guarantee.

The clock starts when the three conditions in section 10 hold.

If the client changes rules, asset, timeframe or material after work has started, the clock stops and a new Validation Scope may be required.

If a delay is attributable to Strateva, the client is told in writing with a revised estimate. No automatic compensation is offered.

12. The client’s obligations

The client undertakes to: supply material they are entitled to hand over for validation; declare truthfully the results they claim to have obtained; supply the data, or enough about it to assemble an equivalent set; and disclose limitations they already know about.

The client is responsible for the lawfulness of the material supplied and for the fact that sending it breaches no third-party rights or confidentiality obligations binding on them.

13. Incomplete or incompatible material

If, after an engagement is accepted, the material turns out to be incomplete or incompatible, Strateva says so before continuing rather than at delivery.

The client may complete the material, in which case the clock resumes, or cancel the engagement under section 20.

Where incompatibility is found before work starts, nothing is charged.

14. Confidentiality and ownership of the material

The material the client sends remains theirs. Strateva acquires no rights over the strategy, the code or the data beyond what is strictly necessary to perform the engagement.

Strateva does not publish, reuse for other clients, or use as training material anything it receives. The examples published on this website are the owner’s own strategies.

The delivered report belongs to the client and may be used freely. The methodology, the tooling and the validation engine are Strateva’s and are not transferred with the report.

15. Handling of code, data and attachments

Material is kept only for as long as needed to perform the engagement and to stand behind the report if its content is later disputed.

Execution takes place in an isolated environment with no access to anything outside the engagement’s frozen inputs.

The client may request deletion of their material once the engagement is closed. The specific retention policy is set out in the privacy policy.

16. What the report and the outcome are

The report states what was checked, on what evidence and with what result, inside the agreed Validation Scope and over the period examined.

The outcome is computed by applying a decision rule frozen before execution. It is not an opinion formed after seeing the result.

“Ready for shadowing” means no reason was found to discard the strategy and that it may be run unfunded, in parallel. It is not authorisation to trade real capital and not a forecast of profitability.

17. No guarantee of a favourable result

No favourable result is guaranteed. An unfavourable result is correct performance of the service, not a breach.

There are no discounts, refunds or price terms tied to what the outcome says. Tying them would give the provider an interest in the answer, which is precisely what this service exists not to have.

18. Technical discrepancy procedure

The client may raise a factual or technical discrepancy within 7 calendar days of delivery, stating specifically what they consider wrong and why.

One reconciliation review is included at no cost where the discrepancy concerns: transcription errors, data incorrectly incorporated, reproducible differences, or demonstrable failures in performing what was agreed.

If an error attributable to Strateva is confirmed, it is corrected, the affected work is re-run, and a new traceable version of the report is issued. The previous document is not rewritten or replaced silently.

An outcome is not changed because of subjective disagreement. The result changes only when the valid evidence changes or an error is demonstrated.

Supplying rules, data, costs, assets, timeframes or benchmarks other than those agreed is not a discrepancy: it is a new Validation Scope and, where applicable, a further chargeable validation.

Four things are kept distinct: correcting an error of ours, clarifying something already in the report, a new validation over a different scope, and a commercial complaint. Only the first means redoing work at no cost.

19. Corrections and new versions

Every corrected version of a report is identified as such and states what changed from the previous one and why.

Earlier versions are not destroyed. A document that changes silently after delivery stops being evidence, which is exactly what the client bought.

20. Cancellation

The client may cancel an engagement before work starts. If execution has not begun, nothing is due; if the price has already been paid, the applicable refund position is stated in the proposal.

Once work has started, cancellation settles the part actually performed, and what has been produced up to that point is delivered to the client.

Strateva may terminate an engagement on finding that the material is unlawful, that the client is not entitled to supply it, or that the subject matter falls outside the accepted scope. Amounts paid for the unperformed part are returned.

21. Right of withdrawal

These terms are addressed exclusively to professionals and businesses contracting within their activity. In that case the consumer right of withdrawal does not apply.

Were the provider to open contracting to consumers, the consumer rules of the provider’s place of establishment would apply in full, including the right of withdrawal, its period, the model form for exercising it, the express request to start early, and proportionate payment for work already performed. That route is not enabled today and this website has no mechanism to record those consents.

Nothing in these terms seeks to exclude or limit mandatory rights that may belong to a consumer. This section has not been reviewed by a lawyer; the reasoning behind it, and what would have to change to accept consumers, is recorded in the repository for that review.

22. Refunds

Nothing is charged where material is declared incompatible before a proposal is issued.

The refund position for an engagement already paid for and not started is stated in the proposal.

There are no refunds tied to what the outcome says, for the reason given in section 17.

23. Liability and its limits

Strateva is responsible for performing the service correctly according to the agreed Validation Scope and to the professional care required.

Strateva is not responsible for the client’s investment decisions or their results. A validation reports what held up under the agreed checks over the period examined, and nothing beyond that.

A clean result lowers risk; it does not prove the absence of a flaw. No finite set of checks can, and the report states its own limitations.

None of the above excludes liability for wilful misconduct or gross negligence, nor any mandatory rights that apply.

24. Data protection

The processing of personal data is governed by this website’s privacy policy, which identifies the controller, the purposes, the legal bases, the processors, the retention periods and how to exercise rights.

The competent supervisory authority and the applicable regime depend on the provider’s place of establishment, to be determined under section 1.

25. Applicable law and complaints

The applicable law and forum will follow the provider’s place of establishment, which is not yet determined (see section 1). Until it is, these terms are not in force.

Any complaint may be addressed first to stan@strateva.ai and will be answered in writing.

26. Contract language

These terms are published in Spanish and English. The client contracts in the language in which the proposal is communicated to them, and that is the contract language for that engagement.

Where the language versions differ, the version in which the accepted proposal was issued prevails.

27. Version of these terms

Version 1.0.0-draft. No effective date: these terms are not in force.

The version applying to an engagement is the one current when its proposal is accepted, and is identified in it. Later amendments do not affect engagements already accepted.

Where documents conflict, the order of precedence is: particular conditions agreed in writing, the confirmed Validation Scope, the confirmed price and deadline, and these general terms.
