Terms of Service

Last updated: 2026-06-07 — Effective: 2026-06-07

Please read these Terms carefully. They include a binding arbitration clause and a class-action waiver in §17 (for users in the United States, where enforceable), important limits on our liability in §13, and an AI-tool disclaimer in §6. By using the Service you accept these Terms.

1. Acceptance & eligibility

By accessing or using deepaidetector.com (the "Service", operated by the entity behind deepaidetector.com — "we", "us", "our"), you ("you", "Customer") agree to these Terms of Service. If you do not agree, do not use the Service.

You must be at least 16 years old (13 in the United States) to use the Service. If you use the Service on behalf of an organisation, you represent that you have authority to bind that organisation to these Terms; "you" then refers to that organisation.

2. What the Service does

The Service provides AI-generated-text detection — a probabilistic likelihood score and supporting signals indicating whether submitted text appears to have been generated by an AI model. The Service may also provide adjacent features (plagiarism comparison, deep-scan strategies, per-paragraph highlighting, exports, API access) per the plan you select.

3. Your account

  • You are responsible for the confidentiality of your credentials and API keys and for all activity that occurs under your account.
  • You must provide accurate registration information and keep it up to date.
  • You must notify us promptly of any unauthorised access at [email protected].
  • One account per natural person on free tiers; organisational seats are governed by the relevant plan (Team / Enterprise).

4. Acceptable use

Our full Acceptable Use Policy is incorporated by reference. In summary, you may not:

  • Use the Service to harass, defame, dox, threaten, or discriminate against any person or group.
  • Use the Service as the sole basis for high-stakes decisions about a person (academic discipline, hiring, firing, immigration, credit, criminal-justice outcomes). See §6 and our AI Detection Disclaimer.
  • Submit content you have no right to submit (eg, third-party confidential information, stolen material, classified data).
  • Scrape, bot, or automate any tier beyond what the published rate limits or your contract permit.
  • Reverse-engineer, decompile, or attempt to bypass the detection model, rate limits, or paywall.
  • Resell, white-label, or sublicense the Service or its outputs except under an Enterprise reseller agreement.
  • Probe, scan, or interfere with the security or integrity of the Service or its sub-processors.
  • Submit malware, illegal content (CSAM, terrorist content), or material that violates applicable law.

5. API terms

  • API keys are personal to your account. You are responsible for their security.
  • You must not share keys, embed them in client-side code (mobile app, JS bundle), or otherwise expose them.
  • Calls are metered per your billing mode (per_word or per_detection). See your dashboard for live pricing quotes.
  • We may rotate keys, throttle abusive traffic, or suspend keys without notice for security reasons.
  • API breaking changes are versioned (/v1, /v2); we give 6 months' notice before deprecating a major version.

6. AI-tool disclaimer (READ THIS)

AI detection is inherently probabilistic. Both false positives (genuine human text flagged as AI) and false negatives (AI text passing as human) are possible and inevitable. No detector — ours or anyone else's — can deliver 100% accuracy. Detection accuracy varies with text length, language, domain, and adversarial techniques (paraphrasers, humanizers).

The Service produces a signal, not a verdict. You agree:

  • Not to make consequential decisions about a person based solely on the Service's output.
  • To preserve the accused person's due-process rights when our score is used in any disciplinary or employment context.
  • To disclose to subjects, where required by law, that an AI tool contributed to the decision.
  • That we are not responsible for downstream uses of detection scores by you or third parties.

See AI Detection Disclaimer, EU AI Act Disclosure, and our published methodology.

7. Subscription, PAYG & billing

  • Subscriptions (Pro $19, Team $79, Enterprise) auto-renew monthly or annually based on your selection. We charge the payment method on file at the start of each billing cycle.
  • Cancellation: cancel anytime from your dashboard. You retain access through the end of the current paid period. We do not pro-rate cancellations.
  • PAYG balances: top-up packs ($10/$50/$100/$500/$1000) never expire while your account is active. They are non-refundable once used. Unused PAYG balance is refundable on request within 14 days of top-up; see §8.
  • Taxes: prices are exclusive of VAT, GST, or applicable sales tax. We collect and remit taxes where required.
  • Failed payments: after one failed charge we email you and downgrade access to the free tier within 7 days. Outstanding balances may be sent to collections.
  • Price changes: we may change pricing with at least 30 days' notice for monthly subs and 60 days for annual subs; you may cancel before the change takes effect.

8. Refunds

Full terms: Refund Policy. Summary:

  • 14-day money-back guarantee on a new monthly subscription, once per customer.
  • Annual subscriptions: pro-rata refund within 30 days of purchase.
  • PAYG top-ups: unused balance refundable on request within 14 days of top-up. Consumed balance is non-refundable.
  • EU/UK/CH consumers have a 14-day statutory right of withdrawal which we honour separately from our money-back guarantee.
  • Australia: nothing in these Terms limits your rights under the Australian Consumer Law.

9. Trials, promotions, beta features

Trials and promotional pricing may convert to standard pricing automatically; we disclose the conversion at sign-up. Beta features are provided "AS IS" and may change or be discontinued without notice; we do not provide SLA coverage for beta features.

10. Service availability & SLA

We aim for high availability but do not guarantee uptime on free, Pro, Team, or PAYG plans. Enterprise customers receive the Service Level Agreement (99.5% monthly uptime commitment with service credits) as part of their order form. We may perform scheduled maintenance with reasonable notice.

11. Privacy & data processing

Your use of the Service is governed by our Privacy Policy, which is incorporated into these Terms. Business customers may execute our standard Data Processing Addendum (DPA), which includes EU Standard Contractual Clauses and the UK International Data Transfer Addendum.

12. Intellectual property

  • Your content: you retain all rights to text you submit. We claim no ownership.
  • Licence to us: you grant us a limited, worldwide, royalty-free licence to process your submitted text solely to provide the Service. This licence is automatically revoked when we delete the data per our retention schedule.
  • No training without consent: we will not use your submitted text to train our detector unless you give explicit, separate opt-in.
  • Detection outputs: the score, paragraph breakdown, explanations, and exports for a given submission are owned by you; you may use them however you wish, subject to §4 and §6.
  • Service IP: the Service itself — including the detection models, rule corpus, code, copy, designs, trademarks — is our intellectual property or that of our licensors. No rights are granted to you except those expressly set out here.
  • Feedback: any feedback you give us about the Service is non-confidential; we may use it without obligation.

13. Limitation of liability

To the maximum extent permitted by applicable law:

  • The Service is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted availability.
  • We are not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including lost profits, lost data, lost goodwill, or business interruption, arising out of or in connection with the Service.
  • Our aggregate liability to you for any and all claims arising out of or relating to these Terms or the Service is limited to the greater of (a) the amount you paid us in the 12 months immediately preceding the event giving rise to the claim, or (b) USD 100.
  • We are specifically not liable for any harm flowing from your or a third party's decisions made on the basis of a detection score (eg, an academic discipline outcome, a hiring decision, an editorial decision). See §6.

Nothing in these Terms limits liability that cannot be limited under applicable law — including liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or breaches of mandatory consumer-protection rights.

14. Indemnity

You will indemnify, defend, and hold us harmless from any claim, damages, and expenses (including reasonable attorneys' fees) arising from (a) your breach of these Terms or the AUP, (b) your use of the Service in violation of law, (c) any decision you or a third party makes based on a detection score, and (d) your submission of content you had no right to submit. This indemnity does not apply to claims that are our fault under §13 or to claims for which indemnity would be unenforceable.

15. Suspension & termination

  • You may close your account at any time from the dashboard.
  • We may suspend or terminate accounts for material breach of these Terms or the AUP, for failure to pay, for legal compliance, or to protect the Service or other users.
  • For non-emergency suspensions we will use reasonable efforts to give notice and an opportunity to cure.
  • On termination, all licences granted under these Terms cease, and we will delete your data on the schedule in our Privacy Policy (subject to legal retention obligations).
  • Sections that by their nature should survive termination (eg, §12 IP ownership, §13 liability limits, §14 indemnity, §17 arbitration, §18 governing law, §22 misc) survive.

16. Third-party services

The Service relies on sub-processors listed in the Privacy Policy. We are not responsible for the acts or omissions of third parties beyond our contractual control. Links to third-party sites are provided for convenience and do not constitute endorsement.

17. Binding arbitration & class-action waiver (US users)

This section applies if you are located in the United States or if US law otherwise governs the dispute. If you are located elsewhere, see §18 and §19 for your applicable forum.

  • Informal resolution first: before filing arbitration you must contact us at [email protected] with a written description of the dispute and proposed resolution. We will negotiate in good faith for 60 days.
  • Arbitration: any unresolved dispute will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, by a single arbitrator, in English, in Wilmington, Delaware, or by video conference at your option.
  • Class-action waiver: claims may be brought only on an individual basis. You waive the right to participate in any class, collective, or representative action against us.
  • Small claims carve-out: either party may bring qualifying claims in small-claims court instead of arbitration.
  • IP carve-out: either party may seek injunctive relief in court to protect intellectual property rights without first arbitrating.
  • Severability: if the class-action waiver is held unenforceable as to any claim, that claim is severed from arbitration and proceeds in court, while the remainder stays in arbitration.
  • Right to opt out: you may opt out of this §17 within 30 days of first accepting these Terms by emailing [email protected] with the subject line "Arbitration Opt-Out" and your account email. Opt-out has no other effect on your relationship with us.
  • Federal Arbitration Act governs the interpretation and enforcement of this section.

18. Governing law & venue

For users in the United States: these Terms are governed by the laws of the State of Delaware, excluding its conflict-of-laws rules. Subject to §17, any judicial proceeding must be brought in the state or federal courts of New Castle County, Delaware.

For users in the European Union, EEA, UK, or Switzerland: nothing in this §18 deprives you of the protection of mandatory consumer-law provisions of your country of habitual residence. You may bring proceedings in your local courts where required by law.

19. Consumer protection (EU/UK/AU/CA)

  • EU/EEA/UK: if you are a consumer you benefit from any mandatory provisions of the law of your country of residence, including the 14-day right of withdrawal where applicable (which we honour separately at §8). The EU's Online Dispute Resolution platform is available at ec.europa.eu/consumers/odr.
  • Australia: our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. Nothing in these Terms excludes those guarantees.
  • Quebec: consumers retain rights under the Consumer Protection Act (CQLR c P-40.1).

20. Export controls & sanctions

You represent that you are not (and are not acting on behalf of someone) on any US, UK, EU, or UN sanctions list, and that you will not use the Service in a manner that would cause us to violate sanctions or export laws. We may refuse service to comply with these obligations.

21. Changes

We may update these Terms. Material changes will be communicated by email at least 30 days in advance, with a banner on the Service. Continued use after the effective date constitutes acceptance. If you do not accept, you must stop using the Service before the change takes effect; we will honour our refund commitments for any prepaid period that becomes unusable.

22. Miscellaneous

  • Entire agreement: these Terms (together with the Privacy Policy, AUP, DPA where applicable, SLA where applicable, and any order form) constitute the entire agreement between you and us about the Service.
  • Severability: if any clause is unenforceable the remainder remains in force.
  • No waiver: failure to enforce a right is not a waiver.
  • Assignment: you may not assign these Terms without our written consent; we may assign them to an affiliate or in connection with a merger or sale of substantially all assets.
  • Notices: we may give notice by email to the address on file; you give notice by email to [email protected].
  • Force majeure: neither party is liable for failure to perform due to causes beyond reasonable control.
  • Relationship: we are independent contractors, not partners, agents, or employees.
  • Headings are for convenience only.
