Terms of Service

Last updated 31 August 2026

These terms are the agreement between you and Antheia. They cover what you can expect from the Service, what we expect from you, and what happens if something goes wrong. Please read them.

✿ ❀ ✿

01Agreement to these terms

These Terms of Service (the Terms) form a binding agreement between you and Antheia (we, us, our) governing your access to and use of the Antheia website and application (the Service).

By creating an account or otherwise using the Service, you confirm that you've read these Terms and agree to be bound by them. If you don't agree, don't use the Service.

If you're using Antheia on behalf of an organisation, you confirm you have authority to bind that organisation, and "you" refers to both you and it.

02Definitions

"Content" means anything you submit to the Service — including the ideas you describe and the answers you select — together with the app designs, screens, and code the Service generates for you.
"Output" means material generated by the Service in response to your input.
"Account" means the account you create to access the Service.
"Terms" means this document, as updated from time to time.

03The Service

Antheia helps you turn an idea into a working app. You describe an idea, Antheia asks you questions, and it generates app screens and code based on your answers.

The Service is under active development. Features may be added, changed, or removed, and behaviour may vary as we improve it.

04Eligibility

You must be at least 13 years old to use Antheia. If you are in the European Economic Area or the United Kingdom, you must be at least 16. If you are under the age of majority where you live, you must have permission from a parent or guardian.

You may not use the Service if you're barred from doing so under any applicable law, or if we've previously terminated your account.

05Your account

You sign in using a Google account. You're responsible for all activity that occurs under your Account and for keeping access to it secure — which in practice means keeping your Google account secure.

You agree to provide accurate information and to tell us promptly at hello@tryantheia.com if you believe your Account has been accessed without your authorisation.

You may not share your Account, transfer it to anyone else, or use anyone else's.

06Fees, plans, and payment

Plans and prices

Antheia offers a free plan and one or more paid plans. The plans available, what each one costs, what it includes, and any usage allowance attached to it are described on our pricing page. Prices are in US dollars.

We may change what the plans include, and we may add, alter, or retire plans. Where a change materially reduces what you're paying for, we'll tell you before it takes effect.

Billing and automatic renewal

Paid plans renew automatically until you cancel. When you subscribe, you authorise us to charge your payment method the then-current fee for your plan at the start of each billing period, and to keep charging it at the start of every following period until you cancel. After you subscribe we'll email you a confirmation setting out your plan, its price, the billing period, the renewal date, and how to cancel.

If you are under the age of majority where you live, any purchase must be made by a parent or guardian who accepts these terms and is responsible for the charges.

Paid plans are billed in advance. Payments are handled by a third-party payment processor; by subscribing you also accept that processor's terms. We never receive or store your full card number.

Cancelling

You can cancel at any time, online, from the billing settings in your account. You don't need to email us, call us, or ask permission. Cancellation takes effect at the end of your current billing period: you keep access to your paid plan until then, and you won't be charged again.

Usage, allowances, and limits

Generating designs, building and editing apps, and running apps you've published all consume computing resources that cost us money. Paid plans include a usage allowance, described on the pricing page. How much of that allowance a given action consumes depends on the work involved, and the same action may consume different amounts on different plans.

In practice a job costs between 1 and 12 credits depending on how much work it involves, and publishing an app costs 5 credits a month for as long as it stays online. Exact amounts depend on the complexity of the request; you can see what each job cost in your billing history.

Unless the pricing page says otherwise, allowances reset at the start of each billing period and unused amounts don't carry over. Where we sell additional usage separately, it is prepaid and, except where the law requires otherwise, non-refundable and not exchangeable for cash.

We apply limits and per-account spend caps to keep the Service available and affordable, and we may change them. We may throttle, restrict, or suspend an account whose usage is automated, abusive, or materially disproportionate — including on a paid plan.

Usage is consumed by the work, not the result. When Antheia generates a design or builds an app, your allowance is consumed based on the work performed — whether or not you're happy with what comes back. If output is wrong, incomplete, or you decide to regenerate it, that usage still counts and we can't restore it. Our own costs are incurred the moment the work runs. If something failed because of a fault on our side, tell us and we'll put it right.

Our records

Our usage metering and billing records, together with our payment processor's records, are the authoritative account of what you used and what you were charged, absent an obvious error.

Price changes

We may change our prices. If a price increase would apply to your plan, we'll email you at least 30 days before it takes effect. If you don't want to pay the new price, cancel before it applies — continuing past that date means you accept it.

Failed payments

If a payment fails, we may retry it and we'll email you. Paid features may be suspended until payment succeeds. If it keeps failing we may cancel your subscription — your account stays open on the free plan and your projects are not deleted.

Taxes

Prices exclude sales tax, VAT, GST, and similar transaction taxes unless we say otherwise. We'll add any tax we're required to collect, calculated from the billing information you give us, which you agree to keep accurate. You're responsible for any tax, interest, or penalty resulting from information that turns out to be wrong. Where a payment processor is required to collect and remit tax as the seller of record, that processor's tax treatment applies to your purchase.

Refunds

Except where the law requires otherwise, fees are non-refundable. Cancelling stops future charges; it does not refund the period you're already in. Usage you've already consumed is not refundable.

We will refund billing errors, duplicate charges, and charges that resulted from a fault on our side — email us and we'll sort it out. We may issue other refunds or credits at our discretion.

If we terminate your paid plan for a reason that isn't your fault, we'll refund the unused portion of your current billing period. If we terminate it because you breached these terms, no refund is due.

Nothing in this section limits any statutory refund, cancellation, or withdrawal right you have as a consumer under the law where you live.

You have no ongoing right to any particular subdomain or published app. If we reclaim a subdomain or remove a published app under these terms, that doesn't entitle you to a refund.

07Your content

You own your Content. These Terms don't transfer any ownership of your ideas or of the designs and code produced for you.

To operate the Service, you grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce, modify, transmit, and display your Content — including transmitting it to third-party AI providers that generate Output. This licence exists solely so that we can run the Service for you, and it ends when you delete the relevant Content or your Account, subject to reasonable backup retention.

You are responsible for your Content. By submitting it you confirm you have the rights necessary to do so, and that it doesn't infringe anyone else's rights or break any law.

We may remove Content that violates these Terms or that we're legally required to remove.

08AI-generated output

Output may be inaccurate, incomplete, insecure, or unsuitable for your purposes. Because of how generative systems work, Output produced for you may also closely resemble Output produced for someone else. You are responsible for reviewing, testing, and validating any Output before relying on it, publishing it, or shipping it to others.

Antheia is a design and prototyping tool. Output is a starting point, not a finished, production-ready product, and it is not professional advice of any kind.

We make no representation that Output is original, non-infringing, secure, or fit for any particular purpose. You are responsible for ensuring that anything you build or release complies with the laws and obligations that apply to you.

09Our intellectual property

The Service itself — including its software, design, interface, and the Antheia name and marks — belongs to us and is protected by intellectual property laws. These Terms grant you a limited, revocable, non-transferable, non-exclusive licence to use the Service in accordance with them. No other rights are granted.

You may not copy, modify, distribute, sell, lease, or create derivative works from any part of the Service, or attempt to extract its source code, except where such restrictions are prohibited by law.

10Feedback

If you send us suggestions, ideas, or feedback about the Service, you grant us an unrestricted, perpetual, royalty-free right to use it without obligation or compensation to you. We appreciate feedback and want to be able to act on it freely.

11Acceptable use

You agree not to use the Service to:

Break any law, or infringe the intellectual property, privacy, or other rights of anyone else
Create or distribute malware, spyware, or anything designed to harm, deceive, or defraud
Generate content that is harassing, hateful, sexually exploitative of minors, or that promotes violence
Impersonate any person or organisation, or misrepresent your affiliation with one
Probe, scan, disrupt, overload, or attempt to gain unauthorised access to the Service or its infrastructure
Scrape or harvest data from the Service by automated means, or use it to build a competing product
Circumvent usage limits, access restrictions, or security measures
Resell, sublicense, or redistribute the Service itself

We may investigate suspected violations and may suspend or terminate accounts involved.

12Third-party services

The Service depends on third-party providers, and may link to or integrate with services we don't control. We're not responsible for those services, their availability, or their content, and your use of them is governed by their own terms.

13Privacy

Our Privacy Policy explains what information we collect and how we handle it. By using the Service you agree to that handling.

14Availability and changes

The Service is provided on an as-is and as-available basis. We don't guarantee that it will be uninterrupted, timely, or error-free. Antheia is a young product, and it may be unavailable for maintenance, upgrades, or reasons outside our control.

We may modify, suspend, or discontinue any part of the Service at any time. Where we discontinue it entirely, we'll make reasonable efforts to give you notice and an opportunity to export your Content.

15Suspension and termination

You may stop using Antheia at any time. You can delete your Account yourself from your account settings, or by emailing privacy@tryantheia.com.

We may suspend or terminate your Account, with or without notice, if you breach these Terms, if we're required to by law, or if your use poses a risk to the Service or to other users.

On termination, your right to use the Service ends immediately. Sections that by their nature should survive — including Content licences already granted for backups, intellectual property, disclaimers, limitation of liability, indemnification, and governing law — survive termination.

16Disclaimer of warranties

THE SERVICE AND ALL OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY.

TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY OUTPUT WILL BE ACCURATE, ORIGINAL, SECURE, OR FIT FOR YOUR PURPOSES.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU. NOTHING IN THESE TERMS LIMITS RIGHTS YOU HAVE UNDER MANDATORY CONSUMER-PROTECTION LAW.

17Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, ANTHEIA WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, ARISING OUT OF OR RELATING TO YOUR USE OF THE SERVICE OR ANY OUTPUT — EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE FULLEST EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS ($100).

THESE LIMITATIONS APPLY REGARDLESS OF THE LEGAL THEORY ON WHICH A CLAIM IS BASED. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

18Indemnification

You agree to indemnify and hold harmless Antheia from any claims, damages, losses, liabilities, and reasonable legal costs arising out of or related to your Content, your use of the Service, anything you build or release using Output, or your breach of these Terms or of any law or third-party right.

19Changes to these terms

We may update these Terms from time to time. When we do, we'll revise the "last updated" date above. If a change is material, we'll take reasonable steps to notify you before it takes effect — for example through the Service or by email.

Continuing to use the Service after a change takes effect means you accept the revised Terms. If you don't accept them, stop using the Service and ask us to delete your Account.

20Governing law and disputes

These Terms, and any dispute or claim arising out of or relating to them, the Service, or any Output, are governed by the laws of the State of New York, without regard to its conflict-of-law principles.

You and Antheia agree that the state and federal courts located in New York, New York have exclusive jurisdiction over any such dispute, and you consent to personal jurisdiction and venue in those courts.

Nothing in this section removes any right you have to bring proceedings in your country of residence where mandatory local law gives you that right.

21General provisions

Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and us about the Service, and replace any earlier agreements or understandings on the subject.

Severability. If any provision is found unenforceable, it will be limited or removed to the minimum extent necessary, and the remaining provisions stay in full force.

No waiver. If we don't enforce a provision, that isn't a waiver of our right to enforce it later.

Assignment. You may not assign or transfer these Terms without our written consent. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets.

Force majeure. Neither party is liable for failure to perform caused by events beyond its reasonable control, including outages of infrastructure or third-party providers, natural events, or acts of government.

Notices. We may send notices to the email address associated with your Account or display them in the Service. You can reach us at the addresses below.

Relationship. These Terms don't create any partnership, joint venture, employment, or agency relationship between us.
