Terms of Service

Version 1.0 — last updated 5 August 2026

These terms are a contract between you and LAVAN LABS LTD, a company registered in England & Wales, company number 17361107, registered office 128 City Road, London EC1V 2NX ("we", "us", "our"). They govern your use of Coworkkit (the "Service") at coworkkit.ai.

By creating an account or using the Service, you agree to these terms. If you don't agree, don't use the Service.

1. Who can use Coworkkit

Coworkkit is a developer tool, and it's offered for use in the course of a trade, business, craft or profession. You may sign up as an individual or as a company — a solo developer is welcome — but by signing up you confirm you're using it for business purposes rather than as a consumer.

If you are in fact a consumer under UK or EU law, nothing in these terms removes or limits the statutory rights you have as one.

You must be at least 18 and legally able to enter into a contract.

2. What the Service is

Coworkkit gives your web application an AI co-worker: it talks with your users by voice, can see the page they're on, and can carry out actions in your application on their behalf.

You install a front-end SDK and one server-side token route. We host the rest — speech recognition, the language model, speech synthesis and the real-time transport.

Scope and limits, stated plainly:

• Browser and WebRTC only. There is no telephony and no mobile SDK.
• The co-worker acts as your signed-in user, within the permissions you give it. It cannot do anything in your application that you haven't exposed to it.
• The Service is billed by voice-minute.
• We may change, improve or discontinue features. If we remove something you materially depend on, we'll tell you by email in advance where we reasonably can.

Beta and availability. Parts of the Service are being rolled out gradually, and some plans or features may be offered on a limited, preview or beta basis. During that period access may be gated — for example by invitation or a waitlist — and beta features may change, be limited or be withdrawn, with availability not guaranteed. Where a feature is in beta, we'll say so. Beta features are provided "as is", and the disclaimers and liability limits in these Terms apply to them in full.

3. Your account, and your users

There are two groups of people here, and the difference matters.

You are our customer. You hold the account, you accept these terms, and our relationship is with you.

Your end-users are the people who use your application and talk to the co-worker. They have no contract with us and no account with us. The relationship with them is yours. You are responsible for:

• your own terms and privacy notice with them;
• telling them the co-worker is available and what it does;
• any consents or notices your own regulator, sector or jurisdiction requires;
• deciding which of your application's actions and data the co-worker can reach.

You're responsible for keeping your API keys and credentials secure, and for everything that happens under your account.

4. What the AI can and can't be relied on for

Read this section rather than skipping it — it describes a real limitation of the product.

The co-worker is powered by large language models and speech systems. It is capable and it is also, sometimes, wrong.

• Output may be inaccurate, incomplete or inappropriate. We don't warrant that it's correct.
• The co-worker takes real actions in your application. You choose which tools and permissions to expose to it, and you are responsible for that choice and for its consequences.
• Keep a human check on anything consequential — anything that moves money, deletes data, sends communications on someone's behalf, or affects a person's rights.
• Don't use it as a substitute for professional advice — medical, legal, financial or otherwise — or in a setting where a wrong answer causes harm, unless you've put your own safeguards around it.

5. Plans, minutes and payment

All prices are in US dollars (USD).

5.1 What a minute is

A minute is a minute of voice-session time. Usage is metered while a session is live — measured roughly every 30 seconds and again when the session ends — and rounded to the nearest metered interval.

5.2 The two kinds of minutes

Plan minutes are spent first; purchased minutes are only used once your plan minutes are gone. This is deliberate — plan minutes expire anyway, so spending them first is in your favour.

5.3 Buying extra minutes

Extra minutes are $0.20 per minute on every paid plan, with a minimum order of $50 (250 minutes). This is a single published rate. Your plan's effective per-minute rate is lower because committing to a plan earns a discount — $0.20 is the standard rate, not a penalty.

Buying extra minutes requires an active paid plan. The free plan can't purchase them.

Nothing is ever charged to you automatically except your recurring plan fee. Extra minutes are bought when you choose to buy them.

5.4 How long purchased minutes last

Purchased minutes are valid for 12 months from your most recent purchase. The clock is rolling — buying more minutes extends the validity of everything you're holding, not just the new ones.

You'll see the expiry date beside your remaining minutes in the portal and at checkout, and we'll email you before minutes are due to expire.

5.5 Purchased minutes are yours

• They survive cancellation and downgrade. If you cancel or move to a cheaper plan, minutes you have already bought remain yours and remain usable — including on the free plan.
• They are not transferable between accounts or organisations, and they have no cash value.
• They are not money. Purchased minutes are prepaid units of the Service. They are not funds, not a deposit, not stored value, and not a payment instrument.

5.6 Free and promotional minutes are different

Minutes we give you — free-plan minutes, launch credits, trial or promotional grants — are not purchased minutes. They may expire sooner, on whatever terms we state when we give them to you; they are never refundable; and they carry no cash value.

5.7 ⭐ Changes apply going forward only

If we change these terms in a way that affects minutes, the change applies only to minutes purchased after the change takes effect. Minutes you have already bought keep the terms that were in force when you bought them — including their price, their validity period and their survival of cancellation.

We will not retroactively shorten, devalue or remove minutes you have already paid for.

5.8 Limits follow your plan, not your minutes

Service limits — concurrent sessions in particular — are set by the plan you're currently on, regardless of how many purchased minutes you're holding. Holding minutes on the free plan gives you the free plan's limits.

5.9 Who you're actually buying from

Payments are handled by Paddle.com Market Ltd ("Paddle") as our authorised reseller and merchant of record. When you buy a subscription or extra minutes, Paddle is the seller of record: Paddle takes the payment, issues the invoice, and handles VAT and sales tax.

That means two sets of terms apply, to two different things:

• These terms govern the Service — what it does, what you can do with it, how minutes work.
• Paddle's buyer terms govern the purchase transaction itself — payment, invoicing, tax, and Paddle's own refund and dispute handling.

Where the purchase transaction is concerned, Paddle's terms apply to it. Nothing in these terms limits any right you have against Paddle as the seller, or any statutory right you have.

Paddle operates its own refund policy and may issue a refund independently of us — for example where the law gives you a right to withdraw from a purchase. Where Paddle refunds a purchase, we'll adjust the minutes on your account to match.

5.10 Billing, failure, changes and cancellation

• Renewal. Paid plans renew automatically each period until cancelled.
• Failed payment. If a payment fails, your account is marked past due and we'll ask you to update your payment method. The Service continues for a short grace period; after that we may suspend it. Purchased minutes are not affected by suspension.
• Cancellation. You can cancel any time. Cancellation takes effect at the end of your current paid period — you keep the Service until then. Plan fees are not pro-rated on cancellation.
• Changing plan. Upgrades and downgrades are pro-rated. You don't receive two plan allowances in one period.
• Price changes. We'll give you at least 30 days' notice by email before a price change, and it takes effect at your next renewal after that notice. If you don't want to continue, cancel before then.
• Tax. VAT and sales tax are handled by Paddle and shown on your Paddle invoice.

Refunds have their own page: Refund Policy.

6. The free plan

The free plan includes 100 minutes per month and requires no payment card.

• A "Powered by Coworkkit" badge must remain visible in any application using the free plan. Removing, hiding or obscuring it is a breach of these terms and we may suspend the account.
• The free plan may be changed, limited or withdrawn at any time.
• Purchased minutes can be spent on the free plan, but new minutes can't be bought from it.

7. Acceptable use

You must not, and must not let your end-users:

• use the Service unlawfully, or to infringe anyone's rights;
• attempt to break, overload, probe, scrape or reverse-engineer the Service, or work around its limits;
• resell or expose the underlying API as a competing service;
• use the co-worker to give medical, legal or financial advice without your own compliance and safeguards in place;
• record or intercept end-users unlawfully, or in breach of any notice or consent obligation you owe them;
• use the co-worker to infer the emotions of employees, workers or students — this is prohibited under the EU AI Act, and it's prohibited here;
• present the co-worker as a human being where the law requires it to be identified as AI (see section 8);
• use the Service to generate content that is unlawful, deceptive, or that impersonates a real person without their permission.

We may suspend immediately where we reasonably believe there's a legal risk, a security risk, or serious abuse.

8. Telling people they're talking to an AI

Under the EU AI Act, the duty to ensure a person knows they are interacting with an AI system falls on the provider of that system — for Coworkkit, that is us, and we are implementing a default AI disclosure within the Service.

Until that default is enforced, you must ensure your end-users are clearly informed that they are speaking with an AI — for example by configuring the co-worker to say so, or by disclosing it in your interface — and you must not disable, remove or obscure any AI disclosure the Service provides.

Certain related duties fall on you as the deployer — in particular disclosure where you use emotion recognition or biometric categorisation (Article 50(3)), and disclosure of AI-generated or manipulated content (Article 50(4)) — and those remain your responsibility.

9. Data protection

How we handle personal data is set out in our Privacy Policy. This section sets out the data-protection terms between us, and forms part of these Terms.

Roles. For your own account, billing and usage data, we are the controller. For the personal data of your end-users — the voice and the words spoken to the co-worker — you are the controller and we are your processor: we process it only to provide the Service to you, on your instructions, and never for our own purposes.

Our commitments as your processor. Where we process your end-users' personal data on your behalf, we will:

• process it only on your documented instructions — including these Terms and how you configure the Service;
• keep the people who handle it under a duty of confidentiality;
• apply appropriate technical and organisational security measures;
• use sub-processors only as listed in our Privacy Policy, under equivalent obligations, and tell you before we add or replace one;
• assist you, so far as the nature of the Service allows, in responding to your end-users' data-protection requests and in meeting your own security, breach-notification and impact-assessment duties;
• at the end of your account, delete or return this data — noting that we do not store your end-users' voice or transcripts in the first place (see the Privacy Policy), so there is little to return;
• make available the information you reasonably need to demonstrate this compliance, and contribute to audits on reasonable notice and subject to reasonable confidentiality and security conditions.

These terms apply to every customer whose end-users' data we process — they are not limited by plan. A standalone or countersigned data processing agreement is available on request, and customers on the Growth plan and above can request negotiated terms.

10. Confidentiality

Each of us may learn non-public information about the other. Neither of us will disclose it, or use it for anything other than the Service, except where disclosure is legally required. This doesn't cover information that's public, already known, or independently developed.

11. Intellectual property

• We own the Service — the platform, SDK, models we've built, documentation and brand. You get a non-exclusive, non-transferable right to use it while your account is active.
• You own your content — your application, your data, and your end-users' data. You give us only the licence we need to run the Service for you.
• We don't train AI models on your data, and we don't let anyone else. Our own systems store no transcripts and run no training pipeline. Our AI processing runs on Google Cloud (Vertex AI), whose terms commit that Google will not use the data we send it to train or fine-tune its models without our permission — and we give no such permission. This is our standing policy, not just a default setting.
• Feedback. If you send us suggestions, we can use them freely, with no obligation to you.

12. What we don't promise

The Service is provided "as is". To the fullest extent the law allows, we exclude all implied warranties, including fitness for a particular purpose, satisfactory quality and non-infringement.

Specifically, we do not promise:

• any uptime or availability level. There is no service level agreement.
• that the Service will be uninterrupted, secure, or free of errors;
• that AI output will be accurate or suitable for your purpose;
• any security certification. We do not hold SOC 2 or ISO 27001.

13. Liability

Nothing here limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that can't lawfully be limited.

Subject to that:

• Neither of us is liable for indirect or consequential loss, lost profits, lost revenue, lost data, lost goodwill or business interruption.
• Our total liability to you, for all claims in aggregate, is limited to the greater of (a) the fees you paid us in the 12 months before the claim arose, or (b) US$100.
• On the free plan, our total liability is limited to US$100.

14. Indemnity

You'll indemnify us against claims, losses and reasonable costs arising from: your application; your end-users; your content; your use of the Service; or your breach of these terms — including any claim brought by one of your end-users.

15. Suspension and termination

• You may cancel at any time, effective at the end of your paid period.
• We may suspend or terminate immediately for breach of these terms, non-payment after the grace period, abuse, security risk, or where the law requires it.
• We may terminate for convenience on 30 days' notice. If we do, we'll refund any unused purchased minutes.
• On termination, your access ends. We'll retain or delete data as described in the Privacy Policy.

16. Changes to these terms

We may update these terms. For material changes we'll give at least 30 days' notice by email to your account address and post the new version here with a new version number and date. Continuing to use the Service after that means you accept the new terms.

Section 5.7 still applies: changes to how minutes work never apply retroactively to minutes you've already bought.

17. General

• Governing law. These terms are governed by the laws of England and Wales.
• Jurisdiction. The courts of England and Wales have exclusive jurisdiction.
• Notices. To us: legal@coworkkit.ai, or LAVAN LABS LTD, 128 City Road, London EC1V 2NX. To you: the email address on your account.
• Assignment. You may not assign these terms without our consent. We may assign them to a successor in connection with a merger, acquisition or sale of assets.
• Entire agreement. These terms, the Privacy Policy and the Refund Policy are the whole agreement between us about the Service.
• Severability. If any part is unenforceable, the rest stands.
• No waiver. Not enforcing something once doesn't mean giving it up.

• Force majeure. Neither of us is liable for failures caused by events outside our reasonable control.
