Terms of Service: Plain Rules for a Free Tool

1. Who we are, and what using the site means

In short: the tool is run by Roviant S.r.l. from Italy; using it means you accept these terms.

Cobalynx (cobalynx.com) is operated by Roviant S.r.l., an Italian limited liability company (società a responsabilità limitata) ("we", "us"), and is built and maintained by Mario Federico, its CEO. You can reach us at contact@cobalynx.com. By using the site you agree to these terms; if you do not agree, please do not use it.

2. The service is free, with no account

In short: a free statistical AI-text and file-provenance checker, with free content certification. No signup, and no payment today; paid hosted tiers are planned.

Cobalynx is a free checker: paste text for a measured AI-likelihood score — scoped to our published evaluation population — or upload a file to read its provenance metadata, and you can turn a “likely human” result into a free content certification. Using it needs no account, and everything the site offers today is free — no payment is taken. Hosted certification tiers are planned, but none are billable yet. How verdicts are computed, what a score does and does not mean, and the system's intended purpose and limitations are documented on the methodology page; the measured error rates are on the evidence page.

3. Verdicts are statistical evidence — never proof

In short: our verdicts are calibrated probabilities. They are effective, measured — and not perfect. No verdict proves who or what authored a text.

Every verdict is a probabilistic estimate with a published error rate, not a determination of fact. A verdict is never proof of authorship — in either direction — and we publish where detection fails as openly as where it works. As our own results surface puts it: “A “likely AI” verdict is probabilistic evidence, not proof. False positives happen; never treat this result alone as grounds to accuse a writer.”

4. Prohibited reliance

In short: never punish anyone on a Cobalynx verdict alone. That use is against these terms.

You agree not to use a Cobalynx verdict as the sole basis for any academic, employment, disciplinary, legal, or contractual decision or sanction against any person. A verdict may inform a fair process that weighs other evidence; it may never close one. If you use verdicts in any process affecting an identifiable person, you must ensure genuine human review of all the evidence — a verdict may inform that review, never replace it. This clause is a condition of use, not advice — it exists because probabilistic evidence used as sole proof produces false accusations, and it reflects the system's stated intended purpose.

5. Provided “as is”, without warranty

In short: we work to keep the tool accurate and available, but we promise neither.

The service is provided “as is” and “as available”, without warranties of any kind, express or implied — including accuracy of any verdict, availability, or fitness for a particular purpose — to the maximum extent permitted by applicable law. Rate limits, queues, and outages can occur at any time.

6. Limitation of liability

In short: for a free tool, our liability is limited as far as the law allows — and no further.

To the maximum extent permitted by applicable law, we are not liable for indirect or consequential damages arising from use of the service or reliance on a verdict, and our total liability for direct damages is capped at one hundred euros (€100). Nothing in these terms excludes or limits liability that cannot be excluded under applicable law — including liability for willful misconduct or gross negligence (Italian Civil Code, Article 1229) and the mandatory rights of consumers.

7. Acceptable use and abuse

In short: use the tool lawfully and manually; no scraping or bulk automation without permission. We may rate-limit or block abuse.

You agree not to: use the service for unlawful purposes or harassment campaigns built on verdicts; scrape the site or query it in automated bulk without our prior written permission; evade rate limits; probe the classifier to build or improve evasion tools; or attempt to disrupt the service. We may throttle, rate-limit, or block traffic that we reasonably consider abusive, at our discretion and without notice.

8. Your content stays yours

In short: you keep all rights to what you submit — and we don't keep what you submit at all.

You must have the right to submit the text and files you check. You retain all rights to them; you grant us only the transient, technical license needed to compute your verdict in memory and return it. We store nothing to license further: submitted content is deleted the moment your verdict is delivered, as described in the privacy policy.

9. Our content and brand

In short: the site, brand, and published evaluations are ours. Our own hash-bound certification is the one authorized certification use; no one else may manufacture a certification from our brand or verdicts.

The site, the Cobalynx name and mark, the detection system, and our published evaluations are our intellectual property. You may share and cite your verdicts and our published pages with attribution. Our own content certification is the single authorized certification use of a Cobalynx verdict: a certificate or badge we issue is bound by SHA-256 to the exact text scanned, is offered only for a “likely human” verdict, and states on its face that it is a statistical assessment, not proof of authorship — see the content certification page and the privacy policy. Apart from that first-party product, you may not use verdicts or our brand to imply endorsement or certification of any text, person, or product, and no third party may present a Cobalynx result as a certification of authorship or otherwise manufacture a certification from our brand or verdicts.

10. Changes to the service; termination

In short: the service is free and may change or end; material changes to these terms get a dated entry below.

We may change, suspend, or discontinue any part of the free service at any time. We may update these terms; material changes are recorded with a date in the history at the end of this page, and continued use after a change means acceptance. If any clause is found unenforceable, the rest remain in effect; these terms are the entire agreement between us about the service.

11. Privacy

In short: your text is processed in memory and deleted on delivery — the privacy page is the full, testable story.

How we handle submitted content, server logs, and analytics is governed by the privacy policy, which is part of how the service works, not marketing: its central promise is enforced by an automated no-persistence test on every release.

12. Governing law — consumers keep their local rights

In short: Italian law and Italian courts by default — but if you are an EU/EEA or UK consumer, you keep your home country's mandatory protections and courts.

These terms are governed by Italian law, and disputes go to the competent Italian courts — except that if you use the service as a consumer in the EU/EEA or the United Kingdom, you keep the protection of the mandatory provisions of the law of your country of residence and the right to bring or defend proceedings in your local courts. We will consider alternative dispute resolution in good faith; contact us first at contact@cobalynx.com.
