Terms of Service

Limns (“we”, “us”) is an independent product run by one developer, and the name the service is sold and contracted under. There is no company behind it. These Terms of Service (“Terms”) govern your access to and use of limns.cc and the Limns service. By creating an account or using the service you accept them. If you do not accept them, do not use the service.

What Limns is

Limns is a single account through which you can send messages to, and generate images with, large language and image models operated by third parties — OpenAI, Anthropic, Google, DeepSeek, and Black Forest Labs directly. We do not build or host the models. We pass your request to the provider you picked, return its answer, and charge you for what it used, at our own rates. Which models are on offer changes; the model list is generated from the catalogue the app runs on and names every model and who serves it, so it is always current.

Eligibility and your account

• You must be at least 13 years old to use Limns, or older where the law of the country you live in sets a higher age for using an online service without a guardian — it is 16 in several EU member states, and in mainland China a person under 14 needs their guardian’s consent. Under that age, a parent or guardian has to agree to these Terms on your behalf and hold the account with you.
• You must be 18 or older to buy credits or start a plan. If you are under 18, someone with legal authority over you has to make the purchase.
• Limns is sold for your own use. If you build it into something of your own, the section on high-risk uses below applies to you, and you answer to your own users for what you put in front of them.
• You are responsible for everything done through your account and for keeping your sign-in credentials secure. Tell us at support@limns.cc if you believe someone else is using it.
• One person, one account. Do not share an account or resell access to it.

Credits, prices and payment

Limns runs on prepaid credits. A new account is granted free credits on sign-up, with no card — once for each email address, so a second account under the same address starts with none. After that you buy credits — as a top-up of an amount you choose, or every month on a plan — and spend them as you use the service. Credits are a prepaid balance for using Limns. They are not money, they carry no interest, and they cannot be transferred to another account or cashed out.

• Chat is charged from the tokens a reply actually used, at the model’s own rate, with any web searches the model ran counted separately.
• Images are charged from what the provider reports for the images it produced. Your balance has to cover the expected cost before the request is sent.
• Rates include our margin over the provider’s list price. What each request cost is itemised in Settings → Spending, per model.
• Each request is priced, and its cost held from your balance, before it runs. One that ends up using more than was held — extra web searches, for example — can take your balance slightly below zero, and further requests are refused until it is back above zero.

Credits from a top-up, the free credits a new account starts with, and credits we add to your account never expire while your account is open. Plan credits do. Each monthly charge grants that month’s allowance, valid only for the billing period it paid for. A plan’s credits are spent before any other credits on your account, and whatever is left of them when the period ends is removed from your balance — when the next month’s charge lands or, if the plan was cancelled or did not renew, shortly after the period ends.

Credits you did not pay for — the ones a new account is granted, anything from a promotion, and credits we put on an account to put something right — have no cash value. They are spent like any other credit and they are never refunded, because there was no payment to send back. Only credits you bought can be.

There are rate limits on how many requests an account can send in a period, and a single reply is capped at a maximum length. They exist so that one account cannot take the service down for everyone, and we may adjust them. A request that hits one is refused and costs no credits.

Each plan also carries a storage allowance for the files and images kept under your account, shown in Settings → Data. What happens to stored images when a plan ends is set out in the Refund Policy.

We may change prices, rates and the credit cost of a model — providers change theirs. A change applies to purchases and usage after it takes effect: it never re-prices a request already made or takes away credits you have already bought. If a change to the price of a plan or to the top-up rate (how many credits a dollar buys) raises what you pay, we give at least 30 days’ notice in the app or by email first, and for a plan the new price applies from the renewal after that notice, so you can cancel before it is charged. The per-request rates — how many credits a request to a model costs — are the exception: they follow the model providers’ prices and can change without notice, and a new rate applies to requests made after the change. A change that lowers what you pay needs no notice; we just apply it.

How you pay

Every payment is handled by Waffo Pancake, which acts as the merchant of record for every order, top-ups and plans alike: Waffo sells the credits to you, collects any applicable sales tax or VAT, appears on your statement, and its own terms as seller apply to that transaction alongside these Terms. Top-ups and plans are priced in US dollars.

We never receive or store your card number. Plans are billed monthly and renew automatically at the end of each period until you cancel. There is no free trial: a plan is charged when you buy it, and that month’s credits are granted by that charge. You can cancel at any time in Settings → Billing, and cancellation takes effect at the end of the period you have paid for. You can switch plans there too, confirming the switch on Waffo’s page. A move to a bigger plan takes effect at once: it is charged the difference between the two monthly prices, the current month becomes the bigger plan’s, credits already spent stay spent, and a new monthly period starts that day. A move to a smaller plan takes effect from the next renewal, which is charged at the new plan’s price and grants its credits; nothing is charged for it until then.

Tax and receipts. Prices are shown before tax; any tax that applies to you is added at checkout. Waffo is the seller: it works out and collects the sales tax or VAT for where you are, and emails a receipt for every payment. The invoice it issues as seller is the tax document for the payment — you can download every one of them from Waffo’s customer portal, signing in with the email address you paid with. To have a business name and tax ID on it, add them to your billing details there. No Chinese VAT invoice (发票) is issued for any order.

Refunds

How refunds work, what is refundable and how to ask is set out in full in our Refund Policy, which forms part of these Terms. In short: within 14 days of a purchase you can have it refunded, less the credits already spent from it (valued at the top-up rate) and the payment processor’s fees; free and promotional credits are never refunded; and anything we got wrong we put right, in full.

Acceptable use

These rules cover everything made with Limns — replies, images and anything you upload — whatever a model would have agreed to produce. You agree not to use Limns to create, upload, request or distribute content in any of these categories:

• Sexual and NSFW content. Pornography or anything sexually explicit, nudity, and sexually suggestive images or text — whoever or whatever it depicts, real or invented.
• Violence and gore. Graphic violence, gore, mutilation or torture, and disturbing or shocking horror imagery; and content that glorifies violence, threatens anyone, or encourages violence, self-harm, suicide, terrorism or violent extremism.
• Hate speech and harassment. Content that attacks, demeans or dehumanises people for their race, ethnicity, nationality, religion, caste, disability, sex, gender identity, sexual orientation or age, and content that harasses, bullies, threatens or intimidates anyone.
• Child sexual abuse material and child safety. Child sexual abuse material in any form — photographic, drawn, animated or generated — and anything that sexualises a minor, depicts a minor in a sexual context, or could be used to groom or exploit one. There is no exception to this, for fiction or anything else, and we report it (see How content is moderated).
• Deepfakes and impersonation. Realistic images or text of a real, identifiable person made without their consent to deceive, humiliate or harm them, including any sexual or intimate depiction of a real person; impersonating someone; passing generated content off as a real record of events; and political or election disinformation.
• Copyright and trademark infringement. Copying or closely imitating someone else’s protected work, characters, logos or brands without the right to, passing something off as someone else’s, and breaching anyone’s privacy or publicity rights.
• Weapons, malware and fraud. Real help in making biological, chemical, nuclear or radiological weapons or explosives; malware; and content meant to breach, overload or defraud a system or a person — phishing, scams, forged documents.
• Anything that breaks the law that applies to you, or the usage policies of the model provider that answered you — those policies apply to anything made here, and we pass them on rather than replace them.

And you agree not to do these things to the service itself:

• Resell it, share an account, or put it behind a product of your own without asking us first.
• Work around its rate limits, its credit accounting or any other protection, or run it from more than one account to get past a limit on one.
• Reverse-engineer it, scrape it in bulk, or use automated means to extract model weights, system prompts, hidden instructions, training data or response patterns from it or from the models behind it.
• Jailbreak a model, inject prompts into one, or otherwise try to get around the safety limits the provider built into it.
• Use it — or what it returns — to train, fine-tune, distil, benchmark or evaluate a competing model or service. This is the model providers’ own restriction as much as ours, and it applies whether the output was generated for you or for anyone else.

Reporting content

If you come across content made with Limns that breaks these rules — something a model returned to you, or something another person made here and published — email support@limns.cc with “Report” in the subject line. Say what the content is and where you found it (a link or a screenshot), and include anything that ties it to an account, such as the address it was shared from. You do not need an account to report, and we do not tell the account concerned who reported it. A rights holder reporting a copyright or trademark infringement uses the same address, and should name the work and show that they hold the rights in it.

How content is moderated

Content that breaks these rules is caught or found in four ways. The automatic checks refuse it on the spot; what happens to an account, a person decides.

• Image requests are checked by us. Before a prompt goes to an image model, Limns checks it with an automated classifier (OpenAI’s moderation model) and refuses one it finds sexual. Before a picture is shown or kept, it is checked the same way for sexual content, graphic violence and self-harm, and a set containing such a picture is withheld. A refused prompt or a withheld set costs nothing. If the check cannot be reached, the request goes on to the provider’s own checks below.
• Every request is checked automatically by the model’s provider. The image models check both the prompt going in and the image coming out, and an image they refuse is never delivered — OpenAI’s moderation on its GPT Image models and Google’s safety filters on Gemini, for example. The chat models are trained and filtered by their makers to refuse the same categories. None of this can be switched off from Limns.
• Reports from anyone, as set out above.
• Notices from model providers. A provider that finds a request from an account broke its policy can tell us, and we treat that as a report.

Every report and notice is read and reviewed by the person who runs Limns. To review one we look at the content it concerns, and at the rest of that account’s content only as far as the report needs — this is the one case, besides a legal obligation, in which we look at what an account has made, and the Privacy Policy says the same. Depending on what we find, we delete the content from our storage, refuse further requests, warn the account, suspend it or close it. Child sexual abuse material closes the account at once; we keep what the law requires us to keep and report it to the National Center for Missing & Exploited Children (NCMEC) or the police.

A report of child sexual abuse material, or of a threat to someone’s life, is dealt with within 24 hours of reaching us; any other report within 2 business days. If you think we got a decision about your account wrong, write to us and we will look at it again.

Your content

What you type, upload and generate stays yours, as far as it can be owned and subject to anyone else’s rights in it. You confirm you have the rights to whatever you upload. We claim no ownership of it and do not use it to train models.

You grant us only the permission needed to run the service for you: to transmit your request to the model provider you chose and return its answer, and to store your threads, your files and the images generated for you so that your own account can show them again, on this device and the next. We do not read them, sell them or train on them — see the Privacy Policy for exactly what we hold, for how long, and what we do not.

Model output

Model output is generated, not verified. It can be wrong, out of date, biased or made up, and two identical prompts can return different answers. You are responsible for checking anything before you rely on it, especially in medical, legal, financial or safety contexts. Output may also resemble content produced for someone else; we cannot and do not promise it is unique or that it is free of third-party rights.

High-risk uses, and telling people it is AI

Some decisions land on a person rather than on you. If you use Limns to produce advice, a recommendation or a decision that affects someone’s health, legal position, money, credit, job, housing, education, insurance or safety, then two things are yours to do, and the service is offered on that condition:

• Someone qualified reviews it before it is acted on or sent out. A model is not the professional, and nothing it returns is advice from us.
• Tell the person it is AI. If output reaches someone directly — a chatbot, an agent, a generated letter or report — say so, at the start of each session, in words they will see.

We cannot check either of these for you. It is the condition, not a recommendation.

Labelling what you make

Several countries now require content generated by AI to be marked as such before it is published or shared — mainland China’s labelling measures for AI-generated content, and the transparency duties of the EU’s AI Act, among others. Whether a rule like that applies to what you make here, and meeting it, is yours: we do not add a label for you. Some providers do write provenance metadata into the images their models generate, and that stays in the file you download unless you strip it. If AI generation services may not lawfully be used where you are, do not use Limns.

Where Limns may be used

The models are run by companies subject to United States export control and sanctions law, and the two payment channels have restricted lists of their own. So you may not use Limns, or let anyone else use your account, in or on behalf of a country or a person under comprehensive sanctions, or for any end use those laws prohibit, developing weapons among them. By using the service you confirm you are not such a person and are not acting for one. We may refuse or close an account to stay on the right side of this, and a channel may refuse a payment for the same reason.

Availability and changes

Limns depends on third-party providers. A model can be withdrawn, renamed, restricted or taken offline by its provider at any time, and we will remove it from the service when that happens; the app moves your request to another model and tells you it did. We may add, change or withdraw features, and we may suspend the service for maintenance or to protect it. We do not promise uninterrupted availability or that any particular model stays on the list.

Suspension and closing your account

You can stop using Limns at any time, and close your account yourself in Settings → Profile — which deletes your conversations, images and files with it. We may suspend or close an account that breaks these Terms, that is being used fraudulently, or where we are required to by law. If we close your account for a reason that is not your fault, we refund the credits you paid for and have not spent — to the method you paid with where Waffo can still send it there, and otherwise another way we agree with you.

If we stop offering Limns altogether, we will say so at least 30 days beforehand, in the app and by email, leave the service running so you can export your conversations and download your images, cancel every plan so nothing renews, and refund the credits you paid for and have not spent, in the same way. Free and promotional credits are not refunded, because nothing was paid for them. This is a prepaid balance, and it is the one promise a prepaid balance has to come with.

Disclaimers

Except where the law says otherwise, the service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement. Nothing in these Terms excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded, and nothing here affects consumer rights you have under the law of the country you live in.

Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential loss, for lost profits, data or goodwill, or for anything arising out of your use of model output. Our total liability for any claim relating to the service is limited to the greater of the amount you paid us in the twelve months before the claim, or the value of the unused credits on your account.

Indemnity

If someone brings a claim against us because of how you used Limns — content you made with it, rights you did not hold, or a law you broke — you agree to cover the reasonable costs of dealing with it.

Changes to these Terms

We may update these Terms. The date at the top says when they last changed. A change that materially reduces your rights takes effect 30 days after we give notice of it in the app or by email, and not before; continuing to use the service after that means you accept the new version. If you do not, stop using the service and, within those 30 days, ask for your unused credits to be refunded, whatever their age. Those from a purchase in the last 14 days are refunded under the Refund Policy. Waffo cannot send the money for an older purchase back to the method you paid with, so for those we settle it another way we agree with you, as the Refund Policy does when something has gone wrong. A change we have to make to follow a law or a regulator takes effect when it must, and a change that only adds something or makes the wording clearer takes effect when we publish it. No change applies backwards.

The rest of the agreement

• Ideas you send us. If you suggest something — a feature, a fix, a complaint that turns into a better design — we may act on it, ship it and keep it, owing you nothing and with no obligation to keep it confidential. That is not a claim on anything else you make here; it is about the suggestion itself. Do not send us anything you need kept secret or paid for.
• If we hand the service on. We may transfer these Terms, and the account and credit balance they cover, to whoever takes over running Limns — we will tell you before it happens, and your credits and your plan carry across on the same terms. You cannot transfer your account to someone else.
• Things outside anyone’s control. We are not liable for failing to provide the service because of something we cannot reasonably control: a provider outage, a network or infrastructure failure, an act of government, or a disaster. We will get it back up as soon as we can, and if an outage is long enough to matter, write to us and we will put it right.
• If one clause fails. A term a court finds unenforceable is narrowed to what is enforceable, or dropped, and the rest of these Terms stands.
• Not enforcing something is not giving it up. If we let a breach pass, we can still act on the next one.
• These Terms, the Privacy Policy and the Refund Policy are the whole agreement between us about Limns, and replace anything said before. Nothing here affects rights the law gives you that cannot be signed away.
• Notices. Ours reach you at the email address on your account, or in the app. Yours reach us at support@limns.cc.

Governing law and disputes

These Terms are governed by the law of England and Wales, without regard to conflict-of-law rules, and the courts of England and Wales have non-exclusive jurisdiction over any dispute arising from them. If you are a consumer, this does not deprive you of the protection of the mandatory consumer law of the country you live in, or of your right to bring proceedings in the courts there. Please write to us first: almost everything is settled by email, and a reply costs nothing.
