TWINii Expert Terms of Service

Twin Inc Ltd (Company No. 16656477)

20 Wenlock Road, London, N1 7GU

Version 1.2

Last updated: 15 September 2026

Effective from: 15 September 2026

Replaces: Version 1.1, August 2026

Schedules A, B and C set out what you earn in each place. You see the one that applies when you publish there, and you agree to it at that point.

These Terms are a legal agreement between you (the "Expert") and Twin Inc Ltd ("TWINii", "we"). By approving your TWINii, you agree to them in full. They sit alongside our general Terms of Use and Privacy Policy. If there is any conflict, these Expert Terms take precedence.

We may update these Terms from time to time. Material changes require 30 days' notice. If you disagree with a material change, deactivate before it takes effect.

1. Key Definitions

Your Work: everything you give us, and the public work of yours that we use to build your TWINii, in each case reviewed and approved by you before your TWINii is published. It includes audio, video, writing, images, voice samples, social posts and transcripts.

Your TWINii: the AI system we build from Your Work. It speaks in your voice, draws on the work you have approved, and stays inside the boundaries you set. It is not you, and it does not contain everything you know.

Voice Model: the AI voice model built from your samples, used only to run your TWINii.

Likeness: your name, image, voice, vocal patterns, mannerisms, persona, and biography.

Approve: the moment you confirm your TWINii represents you and is ready. Nobody can reach it until you publish it.

Publish: the moment you make your TWINii live in one of the places in 5.5.

Audience Member: anyone interacting with your TWINii via the Platform.

Net Revenue: gross revenue attributable to your TWINii, less only the deductions in section 4.2.

Platform: the TWINii apps, websites, widgets, and APIs.

Material change: a change to these Terms that reduces what you earn, narrows your rights, or puts a new obligation on you. Fixing a typo, clarifying wording that already meant the same thing, adding a feature, or complying with a legal requirement is not a material change.

2. What You Agree To

By approving your TWINii, you confirm:

(a) you grant the rights in section 3

(b) you consent to AI voice synthesis of your voice

(d) you are 18 or older and legally able to enter this agreement

(e) you agree to the revenue share in section 4

(f) you consent to the data processing described in section 7

(g) you understand your TWINii is clearly identified to audiences as AI

3. Grant of Rights

3.1 Content licence

You grant us a non-exclusive, worldwide, royalty-free (subject to revenue share) licence to use, reproduce, modify, and process Your Work solely to:

(a) build, train, run, and improve your TWINii on the Platform

(b) deliver Platform services to Audience Members

3.2 Limits on use of Your Work

Your Work is used only to build, train, run and improve your own TWINii. It will not be used:

(a) to train foundation models, whether ours or a third party's

(b) to build, train or improve any other Expert's TWINii

(c) to create or improve any model, system or feature designed to replicate, simulate or substitute the Expert outside that Expert's own TWINii

We may use operational and performance data that contains none of Your Work, such as latency, error rates, retrieval performance and safety signals, to improve the Platform.

Your Work cannot be anonymised. Something distinctive, such as a named framework, a methodology or a passage from your writing, identifies you on its own, whatever labels are removed from it. We therefore never rely on anonymisation as a basis for using Your Work. This section governs its use instead.

These limits are permanent. They continue to apply after your TWINii is deactivated and after this agreement ends.

3.3 Voice and Likeness

You grant us a non-exclusive, worldwide licence to create synthetic reproductions of your voice and Likeness solely to run your TWINii.

We will not:

(a) licence or share the Voice Model with any third party

(b) use the Voice Model to train any other AI system

We protect the Voice Model with encryption at rest, encryption in transit, and role-based access controls.

3.4 You keep ownership

You retain all rights, title, and interest in Your Work and Likeness, including moral rights. Nothing here transfers your IP to us.

3.5 Marketing use

We may use your name, Likeness, and excerpts of Your Work to promote the Platform. For any material campaign featuring you prominently, we will:

(a) share mockups at least 7 days before publication

(b) give you 5 business days to approve or reject (approval not unreasonably withheld)

(c) not associate you with political causes, controversial content, or third-party endorsements without your prior written consent

(d) action removal requests within 3 business days

3.6 Duration

These licences continue while your TWINii is active. On deactivation:

(a) the content licence ends, with up to 30 days to wind down

(b) the Voice Model is deleted within 90 days, with written confirmation

4. Revenue and Payments

4.1 Split

What you earn depends on where your TWINii is live. Each place has its own schedule:

Schedule A: The TWINii app
Schedule B: Your TWINii page
Schedule C: Your website

You agree to a schedule when you publish in that place, and only then. Sections 4.2 to 4.5 apply to all of them.

4.2 Net Revenue

Net Revenue applies only where a schedule says so.

Gross revenue less only these deductions:

(a) App store commissions (Apple, Google, typically 15 to 30%)

(b) Payment processing fees (Stripe or equivalent)

(d) Direct Infrastructure Costs: cloud hosting and AI compute tied solely to your TWINii, charged at actual metered vendor cost, with no mark-up, and never as a share of general platform overhead

If Direct Infrastructure Costs are expected to increase materially, we will notify you in advance.

Nothing else is deductible. Our R&D, marketing, salaries, overheads, fundraising, legal fees, and general corporate costs come out of our share.

4.3 Payments

We pay via Stripe Connect (or a successor we give reasonable notice of). Payouts trigger automatically once your balance reaches the payout threshold, which is shown in TWINii Studio. Smaller balances roll over. We give you 30 days' notice before raising the threshold. On deactivation, any remaining balance is paid within 30 days regardless of threshold.

4.4 Taxes

You handle all taxes on your share. We withhold only where the law requires it.

You do not invoice us. We work out your share and pay it automatically. Where a VAT invoice is needed, we raise it on your behalf under a self-billing arrangement, and you agree to accept invoices raised that way. You will not raise your own invoice for the same payment.

If you are or become VAT registered, tell us your registration number within 30 days. We add VAT to your payments from the date you tell us, and show it on the self-billed invoice. Tell us if you deregister.

If you are not VAT registered, no VAT is added to your share.

4.5 Queries

If you believe a payment or deduction is wrong, email us within 90 days of the statement. We respond within 14 days explaining how the amount was calculated. Any confirmed underpayment is paid with the next payout.

5. Your TWINii

5.1 What it is

Your TWINii is built from Your Work using our AI. It is a system, not a person. Responses are generated algorithmically and may not always reflect your exact views.

5.2 Preview and approval

We give you a reasonable chance to review and test your TWINii before it goes live. Take as long as you need: nothing goes live without you clicking "Publish", and there is no deadline for raising concerns, before or after publication. Section 5.4 sets out your ongoing rights.

5.3 Ongoing

We monitor outputs against our AI safety rules (section 8). You can report concerns at any time and we will investigate promptly. You can add to Your Work whenever you like, and you can ask us to remove specific parts of it from training: we will remove it from active pipelines within 30 days and confirm in writing. If full removal is technically impossible we will document the reason and apply reasonable mitigations. Your UK GDPR Article 17 rights apply.

5.4 Ongoing quality control

You may review your TWINii's responses at any time and request corrections. We will action corrections to prompts, source content or boundaries within 2 business days and confirm in writing. Anything you flag as urgent, including anything you consider inaccurate, off brand or potentially damaging, we will action within 24 hours.

You may add or restrict topic boundaries at any time.

You may pause your TWINii at any time from your dashboard while a concern is looked into. A pause takes your TWINii offline immediately and is not a deactivation: your content, Voice Model and settings are retained, and you can bring it back live when you are satisfied.

5.5 Where your TWINii appears

Your TWINii is not reachable by anyone until you publish it. You choose where, and each place is separate.

The TWINii app, on the terms in Schedule A
Your TWINii page, on the terms in Schedule B
Your website, on the terms in Schedule C

Publishing in one place does not publish in any other. You agree to that place's schedule at the point you publish there, in addition to these Terms.

You do not agree to these Terms again. They were agreed when you approved your TWINii, and they cover everything you do from that point on. A schedule adds only what is specific to that one place, including what you earn there.

6. Your Obligations

You must:

(a) be 18 or older

(b) have the legal right to enter this agreement

(d) only give us Work that is original to you or fully licensed, that does not infringe third-party rights, contain unlawful or defamatory material, or mislead

You must not:

(a) interfere with our AI safety systems

(b) use the Platform to promote illegal activity, hate, or discrimination

(d) impersonate another person through your TWINii

Tell us promptly if your circumstances materially change, you receive any third-party claim relating to your TWINii, or you become aware of a breach of these Terms.

7. Data Protection

7.1 Compliance

Each party complies with applicable data protection law, including UK GDPR and the Data Protection Act 2018.

7.2 Voice biometric data

Voice data is special category data under UK GDPR Article 9. You give your explicit consent for one purpose: running your TWINii.

Running it includes testing it. We run internal test conversations through TWINiis, including yours, to check that a change works before it reaches your audience. Nobody outside our team hears them, they are never published, and the audio is not kept once the test is done.

We use your voice data for nothing else. No foundation model training, no other Expert's TWINii, no research.

Withdrawing this consent deactivates your TWINii, because it cannot run without a voice. You can withdraw at any time in TWINii Studio.

7.3 Retention

Voice data and the Voice Model are kept for a maximum of 90 days after deactivation, then securely deleted with written confirmation.

7.4 Audience data

We are the data controller for Audience Member data.

Your dashboard shows you conversations Audience Members have had with your TWINii, so you can see how it is performing and improve it. Audience Members appear under a pseudonymous reference that stays the same for that person, so you can recognise a returning visitor. You do not receive their name, email address, photograph or account details from us.

Anything an Audience Member writes or says in a conversation is visible to you, including personal details they choose to share about themselves. We tell them so before they start.

You must not: attempt to identify an Audience Member; combine what you see with information from any other source in order to identify them; export, publish or share conversation content outside your use of the Platform; or use it to contact or market to them. These obligations continue after deactivation.

7.5 Security and breach

We use encryption at rest, encryption in transit, and access controls. If a breach affects your data we notify you within 72 hours with enough detail to assess impact. If the Voice Model is involved, we include the safeguards in place and remediation steps.

8. AI Safety Rules

All TWINiis follow these rules:

(a) Transparency: your TWINii is always identified as AI. It never claims to be you in real time.

(b) Prohibited content: no sexually explicit material, no promotion of violence or self-harm, no regulated professional advice (medical, legal, financial), no illegal activity, no discrimination.

(d) Accuracy: your TWINii does not fabricate credentials or factual claims on your behalf.

(e) Consent and respect: no manipulative, coercive, or deceptive interactions with audiences.

(f) Data minimisation: interactions retain only what is needed to run the Platform, to provide memory features to Audience Members, and to show you the conversation history described in section 7.4, as disclosed in our Privacy Policy.

We may update these rules for legal, regulatory, or technical reasons, with 30 days' notice for material changes. If an update materially restricts your TWINii in your domain, you may deactivate without penalty within 30 days.

We comply with the UK Online Safety Act 2023, the UK AI regulatory framework, and (where relevant) the EU AI Act.

9. Intellectual Property

9.1 Ownership

Your IP stays yours. Our technology, Platform, and systems stay ours.

9.2 Outputs

(a) Outputs involving your voice or Likeness belong to you. You can request archives and use them personally or to promote your work.

(b) Outputs materially derived from Your Work belong to you. An output is materially derived if it could not have been produced without Your Work. You grant us a licence to store, display and serve those outputs on the Platform for the purposes in 3.1(a) to (c).

(d) We may use all outputs to operate and improve the Platform, subject to the limits in section 3.2.

9.3 Export

You can request a machine-readable export of your TWINii's interactions, outputs, and analytics. We provide it within 30 days. Interactions are exported under the same pseudonymous references described in section 7.4, and the obligations in that section apply to the export.

9.4 Change of control

If we are acquired or merged, we notify you within 10 days. The successor must assume these Terms. If they will not be bound by equivalent protections, you have 30 days to deactivate without penalty, with full payout of accrued revenue.

10. Deactivation

10.1 By you

Deactivate any time via your dashboard or by email. We suspend within 24 hours and remove your TWINii within 30 days.

10.2 Emergency takedown

For urgent removal, email [email protected]. We suspend within 24 hours.

10.3 By us

We may suspend or deactivate your TWINii if:

(a) you materially breach these Terms and do not fix it within 14 days of written notice with evidence

(b) your conduct poses an imminent risk of harm

(d) your conduct could seriously damage the Platform's reputation

Except for imminent harm, we give written notice with evidence, allow 14 days to fix, and explain our final decision. For imminent harm, we suspend first and explain within 5 business days.

10.4 Appeals

You may appeal any suspension or deactivation in writing within 14 days. A senior team member not involved in the original decision reviews it and responds within 10 business days. If your appeal is upheld, we reinstate your TWINii and cover any documented lost revenue.

10.5 What happens

On deactivation:

(a) TWINii removed within 30 days

(b) Your Work returned or deleted within 60 days (your choice), with written confirmation

(d) accrued revenue paid within 30 days regardless of threshold

(e) profile and marketing materials removed within 30 days

(f) no conversation archives, transcripts or extracts retained. We may keep aggregate statistics, such as volumes, durations and error rates, which contain none of Your Work and no conversation text

11. Indemnities and Liability

11.1 You indemnify us

You indemnify us against claims arising from:

(a) your breach of these Terms

(b) Your Work infringing third-party rights

You are not responsible for AI-generated outputs not derived from Your Work, including hallucinations or model errors.

11.2 We indemnify you

We indemnify you against claims arising from:

(a) our breach of these Terms

(b) our technology or Platform (other than claims stemming from Your Work)

(d) AI outputs not derived from Your Work

(e) unauthorised third-party use of your Voice Model or synthesised voice, during or after your participation. This survives deactivation.

(f) regulatory investigations arising from our non-compliance

11.3 Procedure

The indemnifying party may take part in the defence and approve settlements (consent not unreasonably withheld). Neither party settles without the other's written consent.

11.4 Cap

Total aggregate liability (including indemnities) is capped at the greater of 12 months' revenue share or £10,000, except as set out in 11.5.

11.5 Unlimited

No cap applies to: death or personal injury from negligence, fraud, anything that cannot be excluded by law, or unauthorised use of the Voice Model or synthesised voice at any time, whether during or after your participation.

11.6 Indirect loss

Neither party is liable for indirect, incidental, special, consequential, or punitive damages, except in cases of wilful misconduct or gross negligence.

12. Confidentiality

Each party keeps the other's confidential information confidential. Exceptions: information that is public, already known, independently developed, or required by law. These obligations last 3 years after deactivation.

This does not stop you from talking about your own experience, sharing these Terms with professional advisors under confidence, or giving honest reviews of the Platform.

13. General

13.1 Law and jurisdiction: England and Wales, exclusive jurisdiction.

13.2 Disputes: good faith negotiation for 30 days, then CEDR mediation in London, then court. Claims under £2,500 can skip mediation. Either party may seek interim relief at any time.

13.3 Entire agreement: these Terms, the Terms of Use, and the Privacy Policy are the full agreement.

13.4 Assignment: you can assign to a management company or agent on written notice (we will not unreasonably object). We can assign to affiliates or successors who assume these Terms.

13.5 Force majeure: neither party is liable for delay caused by circumstances beyond reasonable control (acts of God, war, terrorism, pandemic, natural disaster). Business decisions, financial difficulties, regulatory enforcement, and changes in law are not force majeure. Suspension above 90 days lets either party terminate without penalty. Revenue continues to accrue during suspension.

13.6 Severability, waiver, third parties: invalid provisions are severed. Delay is not waiver. No third-party rights under the Contracts (Rights of Third Parties) Act 1999.
