Terms and conditions

The rules for using headcast. Please read section 9 before you upload anyone.

Last updated 16 September 2026.

1. Who we are

headcast is run by Sam Adeniyi, a sole trader in the United Kingdom, as a service at staging.headcast.ai that turns a written script into a talking-head video. We are not registered for VAT, so no VAT is charged and none is shown on a receipt.

The way to reach us about anything on this page is [email protected]. We answer by email.

2. These terms

These terms are the contract between you and us. They apply when you make an account, buy minutes, submit a video or use our API.

If you use the service for your business, you agree to them as a business. If you use it for yourself and not for a business, you are a consumer and you keep your legal rights as a consumer. Nothing here takes those rights away. Where a clause could not lawfully apply to a consumer, it does not apply to you.

If you accept these terms for a company, you confirm you are allowed to bind that company.

3. What the service does

You give us a script and a presenter. A presenter is one photograph of a person's face plus a short sample of that same person speaking, 8 to 30 seconds long. We make a video in which that person's likeness speaks your script in a copy of their voice, with generated pictures and short clips for the parts where they are not on screen. You get a 1080p mp4 file to download.

Scripts run from 30 to 6,000 words, up to 30 minutes of finished video. Uploads are limited to 12 MB per request. An account can hold up to 50 presenters. The avatar engine we use is HeyGen Avatar IV.

Access is by invitation at the moment. You can join the waitlist with your email address and an optional note.

4. Your account

You need an account. Keep your password, your two-step codes and your API keys to yourself. Anything done with your key or your session is treated as done by you. Tell us at once if you think someone else has access.

You must be 18 or over. Accounts are for adults.

5. How an order is made and accepted

When you submit a video you are making an offer to buy. The contract for that video starts when we accept the video for rendering, which is when its minutes are reserved and it enters the queue. Until then nothing is agreed and nothing is charged.

When you take a plan, the contract for the subscription starts when the first payment is taken and the month's minutes appear on your account. It renews each month, or each year if you chose yearly billing, until you cancel it from the billing page; cancelling stops the next renewal and your minutes work until the end of the period you paid for.

6. Price, VAT and payment

The price is From $99 a month. Each plan is a monthly or yearly subscription that comes with a set number of minutes of finished video every month: Starter $99 for 99 minutes, Creator $299 for 340, Pro $699 for 850, Max $1,299 for 1,700. Unused minutes do not carry over to the next month. If you need more than your plan's minutes in a month, you can buy packs of minutes at $1.00 each, the same on every plan, paid at the time of purchase; bought minutes do not expire. A video is only accepted when your balance covers its estimated length. Moving to a bigger plan applies at once and you pay the difference for the rest of the period; moving to a smaller plan applies from the next renewal. Cancelling applies from the next renewal too: the period you have paid for runs to its end and is not refunded (section 15).

Payment is taken by a third-party payment provider. We never see or store your card number. We keep only the card brand, the last four digits and a token the provider gives us, so that renewals and minute packs can be charged.

Our VAT status is marked to be confirmed in the box at the top. Until that is settled, prices are shown as they are charged and any VAT position will be stated on your receipt.

If a payment fails or is reversed, we can pause your account and remove minutes that were not paid for.

7. Minutes and how they are counted

Minutes are prepaid credit for our service. They are not money, not e-money and not a stored value you can spend anywhere else. You cannot transfer them to another account or cash them out.

There are two kinds. Plan minutes come with your subscription each month and are for that month: whatever is left when the month ends is gone and is not refunded. Bought minutes (minute packs) do not expire and are used after your plan minutes.

When we accept a video we reserve an estimated number of minutes. When the render finishes we settle the reservation against the real length of the finished video and give back the difference. The smallest charge for a video is one minute. If a render fails, the whole reservation goes back to your balance automatically.

We keep a record of every minute that moves on your account, in and out, so that you and we can check any charge.

8. The licence you give us

You keep ownership of everything you upload. You give us a licence to store, copy, change and process your photograph, voice sample and script for one purpose only, which is producing, delivering and storing the videos you ask for, and supporting you if something goes wrong.

To do that we pass parts of your material to the companies that run the generation steps for us. That includes the presenter's photograph and text taken from your script. Section 13 explains that these companies exist. The privacy policy explains what goes where.

We do not use your photographs, voice samples, scripts or videos to train our own models, and we do not sell them. The licence ends for any item when you delete it, except for copies in backups, which age out.

9. Faces and voices you upload

The same rule covers any other person who appears in what you upload, and any music, logo, brand or footage in your material.

10. What you may not make

You may not use the service to make or publish:

• anything that pretends to be a real person, company or public body in order to mislead, including fake endorsements, fake news reports and anything designed to be taken for a real recording;
• political campaigning, election material, or anything aimed at influencing a vote or a referendum;
• sexual or nude content, or anything sexualising a person;
• content that features or is about children, or that is aimed at children;
• harassment, bullying, threats, hate speech, or content that targets a person or a group;
• medical, legal, financial or safety advice presented as if it came from a qualified professional, unless the person speaking is that professional and has agreed;
• scams, phishing, investment pitches, fake giveaways and anything designed to get money or data by deception;
• anything unlawful in the United Kingdom or in the country where you publish it, and anything that breaks someone else's rights.

You may not resell raw access to the service as if it were your own product without asking us first, and you may not try to break, overload or reverse engineer it.

11. Your video and how you publish it

You own the finished video, as far as we can grant that, once its minutes have been settled. You can use it commercially. We claim no rights over it and we do not publish your videos.

Because the output is synthetic, you are responsible for how it is published. Platforms and advertising rules increasingly require you to label content that shows a person who is generated or altered, and some countries require it by law. Check the rules of the platform you publish on, use its disclosure setting where there is one, and label the video yourself where labelling is required. We do not do this for you.

Generated video can carry a mark that identifies it as generated. Do not try to remove one.

12. When we can refuse, stop or suspend

We can refuse a presenter or a script, stop a render that has started, and take down a video, if we reasonably think it breaks section 9 or section 10, or if a provider we depend on refuses it.

We can suspend or close your account for a serious or repeated breach. If we do that, minutes you have not used are refunded, unless the breach involved fraud or unlawful content, or a payment was reversed. If a render is stopped, its reserved minutes go back to your balance.

Where it is reasonable to do so we tell you why, and you can reply to [email protected] and ask us to look again.

13. The service depends on other companies and can change

Parts of the work are done by other companies: payments, avatar rendering, voice cloning, picture and clip generation, storage and email. If one of them changes its service, its prices or its rules, or stops working, our service can change too. We can add, change or drop features, and we can change providers.

If a change makes the service materially worse for you, tell us and we will refund minutes you have not used.

14. What we do not promise

We provide the service with reasonable care and skill. We do not promise a particular creative result. Generated video is not predictable. A likeness may not satisfy you, a voice may not sound the way you hoped, a picture may be wrong, and a render can fail outright.

Plan on about 40 minutes for a 10 minute video. That is an estimate, not a deadline. We do not promise the service will always be available.

15. Refunds and cancelling

Failed renders. If a video fails, its reserved minutes go back to your balance automatically. You pay nothing for it. That is the refund the service is built around, and it happens without you asking.

Subscriptions are paid in advance and are not refunded. Each period is paid for at its start, and the plan minutes for that period are made available at once. You can cancel at any time from the billing page; your plan then runs to the end of the period you have paid for and does not renew. We do not refund the current period, in full or in part, and we do not refund plan minutes you did not use.

Minute packs are paid for at the time of purchase and are not refunded, except under the 14 day right below if it applies to you.

What is not a reason for a refund. Changing your mind, no longer needing the service, not using minutes you paid for, a change in your own plans or budget, or deciding to use a different service. Our prices and the prices of others may change; a purchase is made at the price shown to you at the time, and a later price, ours or anyone else's, does not entitle you to money back.

When we do refund. If we did not provide the service with reasonable care and skill, or a charge was taken in error, tell us at [email protected] and we will put it right, which may mean minutes back on your account or money back to the card you paid with. This does not limit your legal rights.

Chargebacks. If you think a charge is wrong, contact us first: we answer, and we can see every minute on your account. A chargeback raised on a charge that matches these terms is treated as a breach of them. We will contest it with the record of your account and your use of the service, and we may suspend the account until it is resolved.

Your 14 day right to cancel, if you are a consumer. If you are buying as a consumer and not for a business, you can cancel a subscription or a purchase of minutes within 14 days of buying it, without giving a reason. Email [email protected] and say you are cancelling. By submitting a video during the 14 days you are asking us to start the service straight away, and you accept that you lose the right to cancel the part of the service that has been performed. In practice: minutes you have not used are refunded; minutes used on a video that finished are not; a video that failed cost you nothing. We refund within 14 days of accepting your cancellation, using the same payment method. This right is for consumers only; if you buy for a business it does not apply.

16. Our responsibility to you

We are responsible for loss you suffer that is a foreseeable result of us breaking this contract or failing to use reasonable care and skill.

We are not responsible for loss that is not foreseeable, for loss of profit, loss of business, loss of contracts or loss of goodwill, for any consequence of the way you use or publish a video, or for a claim by a person whose face or voice you uploaded without permission.

Our total liability to you, for everything connected with the service, is limited to the greater of the amount you paid us in the twelve months before the claim, or one hundred pounds.

Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for a breach of your legal rights as a consumer, or for anything else that cannot lawfully be limited.

17. Your responsibility to us

If someone brings a claim against us because of material you uploaded or a video you published, you will cover our losses, including reasonable legal costs, as long as we tell you about the claim promptly and do not settle it without asking you. This applies whether the claim comes from a person whose face or voice was used, a rights holder, a regulator or a platform.

This section does not apply to you as a consumer to any extent that would be unfair.

18. Your data

How we handle personal data, including the photographs and voice samples you upload, is set out in our privacy policy. It forms part of your agreement with us.

19. Complaints and going to court

If something has gone wrong, email [email protected] with your account email and what happened. We aim to reply within five working days and to settle complaints without formality.

If we cannot settle it, you can take the matter to court. Nothing here stops you doing that.

20. Changes to these terms

We can change these terms. If a change matters to you we will email the address on your account at least 14 days before it takes effect, and the date at the top of this page will change. If you do not accept a change, stop using the service and ask us for a refund of minutes you have not used.

21. Which law applies

These terms are governed by the law of England and Wales, and the courts of England and Wales deal with any dispute. If you live in Scotland or Northern Ireland you can also bring a case in your own local courts.

22. This is not legal advice

We are not a law firm. Nothing on this page is legal advice about your own use of the service. Whether you may use a particular person's face or voice, and what you must disclose when you publish a video, depends on your situation and where you are. If you are unsure, take your own advice before you upload.
