Terms of Service

Version 1.0 — 12 June 2026. EnterTheLoop Ltd, registered in England and Wales (company number 17169996), registered office Hunters Moon, Little Lane, Saunderton, Princes Risborough HP27 9NW. You accept this document electronically; the version and content hash you accept are recorded against your account.

1. Who we are

1.1 These Terms of Service ("Terms") are between you and EnterTheLoop Ltd, a company registered in England and Wales (company number 17169996) with its registered office at Hunters Moon, Little Lane, Saunderton, Princes Risborough HP27 9NW ("EnterTheLoop", "we", "us", "our"). We operate the platform at entertheloop.ai (the "Platform").

1.2 You can contact us at support@entertheloop.ai, or for anything about your personal data at privacy@entertheloop.ai, or by post at our registered office.

1.3 The Platform enables verified UK clinicians to carry out AI evaluation, judgement-signal, RLHF (reinforcement learning from human feedback) and clinical scenario-review tasks, and enables us to assemble, license and sell the resulting evaluation datasets and related products.

2. Definitions

2.1 In these Terms:

• "Contributor" means a person who holds a Verified Account and has executed the Contributor Agreement;
• "Contribution" means any work, judgement, rationale, critique, rubric, scenario, annotation, ranking, rating or other material created or submitted via the Platform;
• "Judgement Data" means the structured signals generated by Platform activity — ratings, rankings, preference selections, judgement-shift responses, calibration and reliability metrics, and associated metadata;
• "Confidential Information" has the meaning given in the Contributor Agreement;
• "Units" means the contribution units described in the Payment Schedule;
• "Payment Schedule" means the payment schedule to the Contributor Agreement, as in force when a Contribution is accepted;
• "Clinical Integrity Rules" means the rules so named in the Acceptable Use & Clinical Integrity Policy;
• "Engagement" means a defined client-specific body of task work;
• "QC-accepted" means accepted following the quality-control review described in the Contributor Agreement and the Payment Schedule;
• "Reliability Report" means the report of that name described in the Contributor Agreement;
• "Verified Account" means an account for which we have completed identity verification and professional register verification under clause 6.

2.2 Headings are for convenience only. "Including" means "including without limitation". References to legislation are to the law of England and Wales as amended from time to time.

3. These Terms and how you accept them

3.1 You accept these Terms by ticking the "I accept the Terms of Service" checkbox presented at account creation, after you have had the opportunity to read the full text and the summary of its key terms. We do not treat browsing or use of the Platform, by itself, as acceptance.

3.2 When you accept, we record: the version number and a cryptographic hash of the full text as presented to you, the checkbox wording, the date and time, the IP address used, and the verification state of your account. We keep every published version of these Terms, and we will give you a copy of the version you accepted on request.

3.3 The following documents are incorporated into these Terms by reference and form part of your contract with us:

• (a) the Acceptable Use & Clinical Integrity Policy;
• (b) the Professional & Conflict of Interest Declaration, which you complete at onboarding; and
• (c) for Contributors, the Contributor Agreement (including the Payment Schedule), which you execute separately by typed signature and which governs your Contributions, the assignment of rights in them, payment, confidentiality and related matters.

3.4 The Privacy Noticeis not a contract term and is not incorporated into these Terms. It is the information we are required to give you about how we use your personal data; you will be asked to confirm you have read it, never to "consent" to it as a condition of using the Platform.

3.5 If these Terms conflict with the Contributor Agreement on any matter concerning Contributions, intellectual property in Contributions, Judgement Data, Units, payment or confidentiality, the Contributor Agreement prevails. If these Terms conflict with the Acceptable Use & Clinical Integrity Policy, these Terms prevail.

4. Eligibility

4.1 To open an account you must:

• (a) be at least 18 years old;
• (b) be based in the United Kingdom;
• (c) hold current registration with the General Medical Council, the Nursing and Midwifery Council, the Health and Care Professions Council or the General Pharmaceutical Council that is not subject to suspension, erasure or to conditions or restrictions relevant to evaluation work — or such other professional registration as we specify for particular task types; and
• (d) act in your own name and on your own behalf.

4.2 You warrant that all information you give us at registration and afterwards is accurate, complete and kept up to date, and that you will tell us promptly if any of it changes.

4.3 You may hold one account. You must not open an account for, or operated by, anyone else, and you must not allow anyone else to use yours.

4.4 You must contract with us personally and not through any company, partnership or other intermediary (including a personal service company). Accounts are for your personal performance of task work only, because clients rely on every Contribution being the personal work of the verified clinician recorded as its author.

5. Your account and security

5.1 You must keep your sign-in credentials confidential and must enable and maintain multi-factor authentication where we make it available.

5.2 You are responsible for activity carried out through your account, except to the extent that the activity results from our failure to maintain reasonable security, or occurs after you have notified us under clause 5.3 that your account may be compromised.

5.3 You must notify us promptly at support@entertheloop.ai if you know or suspect that your credentials have been lost, stolen or used by anyone else. We will then secure the account and you will not be treated as responsible for subsequent unauthorised activity.

5.4 You must not impersonate any person, misrepresent your identity, qualifications, registration or specialty, or create an account using anyone else's details.

6. Verification

6.1 Before you can perform tasks, we verify your identity and your professional registration. An account becomes a Verified Account when both checks are complete.

6.2 Identity verification. You may verify your identity by either route, and both have equal standing:

• (a) biometric verification (automated face-match and liveness check by our verification provider), which we will only use with your explicit consent, given separately at the point of verification and withdrawable as described in the Privacy Notice; or
• (b) manual document review by our staff, which takes up to 5 working days.

Choosing manual review makes no difference to your account, your task access or your standing. How each route uses your data, and the immediate deletion of biometric data on completion of verification, are described in the Privacy Notice.

6.3 Register checks. We check your registration against the public register held by your regulator and record your registration number, registration status and the date we checked. We rely on our legitimate interest in maintaining a verified clinician panel as the lawful basis for these checks, as explained in the Privacy Notice; we do not ask for, and you should not send us, fitness-to-practise history.

6.4 Re-verification. We may repeat identity or register checks at reasonable intervals, or where we have a specific reason (for example, a client or regulatory requirement attached to an Engagement, or information suggesting your details have changed). We will tell you when re-verification is required and give you a reasonable time to complete it; task access may be paused until it is complete, but accrued Units and fees are unaffected.

6.5 Duty to notify. You must tell us promptly if your professional registration lapses, is suspended or erased, or becomes subject to any condition, restriction, undertaking or investigation relevant to your platform work.

7. The Platform service

7.1 The Platform provides access to AI evaluation, judgement-signal, RLHF and clinical scenario-review tasks, calibration and reliability scoring, and related features. Task content may be synthetic, anonymised or simulated clinical material; we will tell you expressly if any task content describes a real identifiable individual.

7.2 No guaranteed work. We do not promise you any volume, frequency or continuation of tasks; task availability is at our discretion and may end at any time. Nothing in these Terms obliges us to offer you work or obliges you to accept it. You may decline, skip or abandon any task at any time without penalty, explanation or effect on your standing.

7.3 We will provide the Platform with reasonable care and skill. Beyond that, and to the extent the law allows, the Platform is provided as available: we do not promise that it will be uninterrupted, error-free or available at any particular time, and we may carry out maintenance, with advance notice where reasonably practicable.

7.4 We may modify, add or withdraw Platform features. If we withdraw or materially change a feature in a way that significantly disadvantages you, we will give you reasonable advance notice, and you may close your account under clause 13.7 with all accrued entitlements honoured.

7.5 Nothing in this clause 7 excludes or limits any right or remedy you have under the Consumer Rights Act 2015 in respect of services not performed with reasonable care and skill.

7.6 Automated decisions. Some Platform decisions that significantly affect you — for example calibration scoring and readiness gating that determine your access to tasks — may be made by solely automated means. Where they are, you have the right to information about the decision, to request review by a human reviewer, to make representations and to contest the decision. How to do this is set out in the Privacy Notice.

8. No clinical advice; no clinician–patient relationship

8.1 The Platform presents synthetic, anonymised or simulated clinical content for AI evaluation and safety-review purposes only. Nothing you produce on the Platform is clinical advice, diagnosis or treatment for any person; no clinician–patient relationship arises between you and any person depicted in task content; and your outputs will not be communicated to patients or used for the care of any identified individual. You act solely as an independent professional evaluator for EnterTheLoop and its clients.

8.2 Your professional obligations continue. The standards of your regulator (GMC, NMC, HCPC or GPhC) apply to your work on the Platform, and you remain responsible for your own regulatory compliance, employer declarations and indemnity arrangements, as set out in the Contributor Agreement and your onboarding declarations.

9. Acceptable use

9.1 Your use of the Platform is subject to the Acceptable Use & Clinical Integrity Policy, including the Clinical Integrity Rules. The headline prohibitions are set out here because we enforce them under clause 13; the Policy contains the full rules.

9.2 You must never:

• (a) include in any Contribution, message or upload any information that identifies, or could reasonably be combined with other information to identify, any real patient or service user — if you realise you may have done so, or suspect task content describes a real identifiable person, you must stop and report it immediately via the route in the Acceptable Use & Clinical Integrity Policy;
• (b) access the Platform by scraping, bots, scripts or any other automated means, or attempt to harvest Platform content or other users' data;
• (c) reverse engineer, decompile or disassemble any part of the Platform, except to the extent that the law allows this despite this clause;
• (d) circumvent, probe or test any security, rate-limiting, access-control or verification measure;
• (e) use task content, Confidential Information, or non-public data, scores, methodologies or outputs obtained through the Platform to build, train, calibrate or benchmark a competing clinical AI evaluation platform, panel or benchmark product. Nothing in this paragraph (e) restricts your use of your own general skill, knowledge and experience, or prevents you from working for any other platform or AI developer generally. After your account closes, this paragraph (e) continues for the same period as the confidentiality obligations in the Contributor Agreement (five years from your last platform activity; indefinitely for trade secrets);
• (f) share your credentials or allow any other person to perform tasks through your account;
• (g) copy, photograph, record, download or otherwise exfiltrate task content, prompts, scenarios, rubrics, gold-standard answers, model outputs under evaluation, or any other Confidential Information, beyond what the task interface itself requires.

The materials in clause 9.2(g) include trade secrets of ours and of our clients; the restrictions in this clause 9, together with our access controls, form part of the reasonable steps we take to keep them secret.

9.3 Some Engagements carry additional engagement-specific confidentiality and handling rules; these are presented to you before the first task of the Engagement and apply alongside this clause.

9.4 For clarity, nothing in this clause 9 restricts your use of your own professional credentials, your CPD records and evidence, or your Reliability Report (see clause 10.2), and nothing in these Terms prevents the disclosures protected by the carve-outs in the Contributor Agreement (regulators, protected disclosures, duty of candour).

10. Intellectual property

10.1 We (or our licensors) own the Platform, its software, design, branding, methodologies, calibration systems, aggregated and de-identified data, and all improvements — nothing in these Terms transfers any of that to you.

10.2 You keep: your professional credentials, your CPD records and evidence, and your Reliability Report, which you may use and share freely.

10.3 Rights in your Contributions and in Judgement Data are governed by the Contributor Agreement, not by these Terms. We grant you a personal, non-transferable permission to access and use the Platform for performing tasks and managing your account, and for no other purpose. We may suspend or withdraw this permission only as set out in clause 13.

10.4 Feedback.If you send us ideas, suggestions, proposals or other feedback about the Platform or our services ("Feedback"), then: (a) you confirm the Feedback does not include anyone else's confidential or proprietary information; (b) we owe you no obligation of confidence in respect of it (this does not affect our duties regarding your personal data, or our confidentiality obligations under any other agreement); (c) we may already be working on something similar; and (d) you assign to us all copyright in the Feedback and, so far as the assignment is not effective until confirmed in signed writing, you grant us an exclusive, worldwide, perpetual, irrevocable, royalty-free, sublicensable licence to use the Feedback for any purpose and will execute any confirmatory document we reasonably request. In respect of Feedback only, you waive your rights under sections 77 to 83 of the Copyright, Designs and Patents Act 1988; so far as this waiver is not effective as a formal waiver under section 87(2) of that Act, it takes effect as an informal waiver and as a contractual undertaking not to assert those rights (section 87(4)). This Feedback waiver is deliberately broader than the moral-rights position in the Contributor Agreement, because Feedback is not attributed content. Feedback is not a Contribution and earns no Units or fees unless we expressly agree otherwise.

11. De-identified and aggregated data

11.1 We may create and use, for any lawful purpose including commercial purposes, statistics, insights and datasets that are aggregated or de-identified such that neither you nor any other individual is identified or reasonably identifiable, applying the Information Commissioner's anonymisation standards in force from time to time. Where we supply a client with pseudonymised data, we remain responsible for the key and the client is contractually prohibited from attempting re-identification.

11.2 Nothing in this clause limits your statutory data-protection rights, which are described in the Privacy Notice.

12. Liability

12.1 Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud, or for any liability that cannot lawfully be excluded or limited. The limits in clause 12.2 also do not apply to your deliberate or reckless breach of clause 9.

12.2 Subject to clause 12.1: neither of us is liable to the other for indirect or consequential loss (that is, loss which does not arise directly and naturally from the breach), loss of profit, or loss of opportunity; and each party's total liability to the other in any 12-month period is limited to the greater of £2,500 and the amounts paid or payable by us to you in the 12 months before the event giving rise to the claim.

12.3 Nothing in these Terms affects your statutory rights as a consumer, including under the Consumer Rights Act 2015, or any right you cannot give up by contract.

13. Suspension and account closure

13.1 Investigatory suspension. We may suspend your access to tasks while we investigate only where we reasonably suspect:

• (a) a breach of the Clinical Integrity Rules;
• (b) a breach of the no-patient-data rule in clause 9.2(a);
• (c) fraud; or
• (d) a serious breach of the security or confidentiality obligations in the Acceptable Use & Clinical Integrity Policy.

These are the only grounds for investigatory suspension. Suspension pending investigation takes effect immediately.

13.2 Reasons and response. If we suspend your task access, we will tell you the reasons (unless prohibited by law) and give you an opportunity to respond, in each case at or promptly after suspension, and we will complete the investigation promptly.

13.3 Confirmed breach. Forfeiture has only the following triggers: fraud (including collusion, gaming of the quality-control or calibration systems, or a materially false declaration under the Professional & Conflict of Interest Declaration), plagiarism, fabrication, breach of the AI-assistance rule, or inclusion of real patient information. If the investigation confirms one of those triggers: the Units, fees and accrued-but-unpaid royalty attributable to the affected Contributions are forfeit as set out in the Contributor Agreement; your other accrued Units, fees and royalty are unaffected; and any accrued, QC-accepted fees will be paid under the Payment Schedule. No other breach of these Terms or of any other document gives rise to forfeiture, and we never withhold or forfeit your whole balance.

13.4 Closure by us.We may close your account for confirmed fraud, repeated confirmed breaches of these Terms or the Clinical Integrity Rules, or loss of the professional registration required by clause 4.1(c). If we close your account for any other reason, we will give you at least 30 days' notice before closure. In every case of closure by us, your accrued entitlements (less only anything forfeited under clause 13.3) survive and are honoured as set out in the Contributor Agreement and the Payment Schedule.

13.5 Serious incidents. Where a confirmed breach involves serious dishonesty or identifiable patient data, we may report the matter to your professional regulator and, where required, to other authorities. This is in addition to, not instead of, the steps in this clause.

13.6 Never for declining work. We will never suspend, deprioritise or penalise you for declining, skipping or abandoning tasks, or for inactivity.

13.7 Closure by you. You may close your account at any time via your settings or by writing to support@entertheloop.ai. Closure does not affect accrued Units or accrued, QC-accepted fees, which are dealt with under the Contributor Agreement and the Payment Schedule. What happens to your data on closure, including the retention we are required by law to maintain, is described in the Privacy Notice.

14. Changes to these Terms

14.1 We may change these Terms only for one or more of these reasons:

• (a) changes in law or regulation;
• (b) security or fraud prevention;
• (c) quality-system calibration;
• (d) new task types or Platform features; or
• (e) requirements of clients or of the Independent Governance Board.

The Acceptable Use & Clinical Integrity Policy may be varied only under this clause 14, for the same reasons and with the same protections, notice and exit rights as these Terms.

14.2 Any change is prospective only. No change affects Units or fees already accrued, Contributions already submitted, or any other entitlement that has already arisen.

14.3 We will give you at least 30 days' individual notice of any change, by email to your registered address and by notice in the Platform, stating what is changing, why, and the date the change takes effect.

14.4 If you do not wish to continue under the changed Terms, you may close your account at any time before the effective date, free of charge, and your accrued Units and accrued, QC-accepted fees will be honoured as set out in the Contributor Agreement and the Payment Schedule.

14.5 We keep a version history of these Terms, with version numbers and hashes, and will provide any past version on request. When a new version takes effect, we will ask you to confirm acceptance of it at your next sign-in and will record that acceptance against the new version hash; we do not treat continued use alone as acceptance. Between the effective date and your next sign-in, the new version applies, subject to clause 14.2. If at sign-in you decline to confirm acceptance, you may close your account under clause 14.4 with your accrued entitlements honoured; you cannot continue to perform tasks under the old version after the effective date.

14.6 Changes to the Contributor Agreement additionally require your re-acceptance by the same typed-signature process used at onboarding, recorded against the new version hash, before you submit further Contributions under the changed version.

15. Complaints

15.1 Service complaints. If you are unhappy with anything about the Platform, contact support@entertheloop.ai. We will acknowledge your complaint within 5 working days and give you a substantive response within 30 days.

15.2 Data protection complaints. Complaints about how we use your personal data are handled under our Data Protection Complaints Procedure: you can complain using the electronic form on the Platform or by emailing privacy@entertheloop.ai; we will acknowledge your complaint within 30 days and respond without undue delay, as required by section 164A of the Data Protection Act 2018.

15.3 The ICO.You also have the right to complain to the Information Commissioner's Office (ico.org.uk) at any time. You do not have to use our procedures first, although we would welcome the chance to put things right.

16. Disputes and governing law

16.1 These Terms are governed by the law of England and Wales. We will try to resolve any dispute through our complaints process first, and we both may agree to mediation through an accredited provider. Either of us may bring proceedings in the courts of England and Wales; this is non-exclusive — if you live in Scotland or Northern Ireland you may bring proceedings in your local courts, and nothing in these Terms limits where you can sue or be sued as a consumer. Ledger, unit-count and royalty-calculation disputes may, at your option, be referred to expert determination as set out in the Contributor Agreement.

17. General

17.1 Severance. Each clause, and each restriction within a clause, is separate and independently enforceable. If any of them is found to be unenforceable, it is treated as deleted to the minimum extent necessary, and the rest of these Terms continue in full force.

17.2 Entire agreement. These Terms, the Acceptable Use & Clinical Integrity Policy, the Professional & Conflict of Interest Declaration and the other declarations you make at onboarding, any engagement-specific notice you accept under clause 9.3, and (for Contributors) the Contributor Agreement (including the Payment Schedule) are the entire agreement between us about access to and use of the Platform. However: nothing in this clause excludes or limits liability for fraud or fraudulent misrepresentation; and nothing in these Terms excludes, limits or replaces any statutory right you have as a consumer or otherwise.

17.3 Assignment. You may not assign or transfer your rights or obligations under these Terms. We may assign or transfer ours to a successor to our business or to a member of our group, provided the successor is bound to honour your accrued entitlements and the protections of the Contributor Agreement under the successor-binding covenant in the Contributor Agreement; we will notify you of any such transfer.

17.4 Third-party rights. No one other than you and us may enforce these Terms under the Contracts (Rights of Third Parties) Act 1999, except as expressly provided in the Contributor Agreement for your estate and personal representatives.

17.5 No waiver. If either of us delays in enforcing any part of these Terms, that does not prevent enforcing it later.

17.6 Notices. We will send notices to your registered email address and, for changes under clause 14, also in the Platform; a notice sent by email is treated as received 24 hours after sending unless we receive a delivery failure. You may send notices to support@entertheloop.ai or to our registered office; your notice is treated as received when we actually receive it.

17.7 Survival. Closure of your account or termination of these Terms does not affect clauses 3.2, 9 (to the extent stated in clause 9), 10, 11, 12, 16 and this clause 17, which continue in force, or any right or liability already accrued.
