Prepaper

Terms of Service

Last updated 23 August 2026

Plain terms for a small product. This is what Prepaper does for you, what it costs, what you own at the end of it, and what we are and are not responsible for.

1.Who you are agreeing with

Prepaper is operated by The Magic of the Desert Business. In this document "we", "us" and "Prepaper" mean that company, and "you" means the person or organisation using the service.

By creating an account or paying for a plan you accept these terms. If you are using Prepaper on behalf of a company, you confirm you are allowed to accept them for that company.

2.What Prepaper does

You describe your app. An image model draws sets of paper-collage props from that description, Prepaper cuts them into transparent objects, and an editor lets you arrange them into animated onboarding slides. You export a folder containing the artwork, a configuration file, and a React Native component you can paste into your project.

The export is designed so that Prepaper does not become a dependency of your app. Once you have downloaded it, it keeps working whether or not you keep an account with us.

3.Your account

You need an account to use Prepaper. Keep your sign-in details to yourself, and tell us promptly if you believe someone else has access to your account.

One account is for one person or one organisation. You must be old enough to enter into a binding contract where you live.

You are responsible for what happens under your account, including credits spent.

4.Credits, plans and top-ups

Everything you generate is paid for in credits. One set of props costs 10 credits. That ratio is fixed: if pricing changes, we change the price of a credit, never the meaning of one, because your credit history is a permanent record and rewriting the unit would rewrite the past.

A plan is a monthly allowance of sets, and the current plans and their allowances are listed on the pricing page. Plan credits are granted when a billing period is paid for and they expire at the end of that period. They do not roll over. That is what makes a plan a plan rather than a stockpile.

Top-ups are one-time blocks of credits at a flat rate per set. Top-up credits do not expire. Top-ups are available to accounts with an active plan.

When you generate, plan credits are spent before top-up credits, so the credits that expire are used first.

Credits are not money. They have no cash value, they cannot be transferred between accounts, sold, or exchanged for currency, and they are usable only inside Prepaper.

5.Payment and cancellation

Payments are handled by Polar, which acts as merchant of record for your purchase. Your card details are entered with Polar and are never sent to or stored by Prepaper. Polar issues your receipt and handles applicable sales tax and VAT.

Plans bill monthly and renew automatically until you cancel. You can cancel at any time from your settings page, which opens the billing portal our payment provider hosts; you can also change plan or update your card there. Cancelling stops the next renewal; it does not end the period you have already paid for, and your plan credits remain usable until that period ends.

If a payment fails or a subscription is revoked, any unspent plan credits from that period expire.

6.Refunds

If a generation fails on our side, the credits it charged are returned to your balance automatically. You do not need to ask.

Credits that have been spent on a generation that produced sets are not refundable, because the work was done and the compute was paid for. This is why the free allowance exists: try the product before you buy a plan.

For anything else, including a charge you did not expect or a plan bought by mistake, write to us. We would rather sort it out directly than have you dispute it with your bank. Refunds of a purchase are processed through Polar.

If a purchase is refunded, any credits it granted are removed from your balance.

7.Free credits

Prepaper gives credits away in two ways: a grant when you sign up with GitHub, and a reward for letting us show your work as an example.

Free credits are a gift and not a purchase. There is a lifetime cap on how many unfunded credits one account can receive, and the signup grant is held for established GitHub accounts. We do not publish the exact eligibility thresholds, because publishing them turns a refusal into a set of instructions.

We may withhold, reverse or cap free credits where we see an account created to farm them, or several accounts controlled by one person. If we get this wrong for you, write to us and we will look at it.

8.What you own

You own the output. The generated sets, the cut-out objects, the slide layouts you compose and the exported component are yours to use however you like, including commercially, with no attribution requirement and no expiry. Prepaper claims no ownership in any of it, and whatever rights we do hold in it we assign to you, as far as the law allows.

One honest caveat. Whether a generated picture can be copyrighted at all is decided by the law where you are, not by us, and in some places a picture a model drew from a prompt cannot be. What is unambiguously yours is the work you do on top of it: which props you keep, how you arrange and sequence them into slides, and the words you write. That composition is the part of the output with the strongest claim to protection, and it is the part Prepaper exists to help you make.

You own what you put in as well: the briefs you write and anything you upload stay yours.

To run the service we need permission to store and process your content: to draw the props you asked for, cut them out, keep your projects so they open where you left them, and build your export. That permission is limited to operating Prepaper for you and it ends when you delete the content or your account.

We do not show your work to anyone else unless you choose to. Publishing and listing, in the next section, are the ways you can, and the showcase reward is the third. Each is something you turn on, never a licence we take by default.

9.Publishing a tour, and the gallery

From the studio or your dashboard you can publish a tour to a public page at a link nobody can guess, and, separately, list it in the gallery at /explore. Neither happens unless you choose it, and you can undo both from the same dialog at any time.

When you publish, you give us permission to host, copy, cache and display that tour, meaning its slides, its artwork, the project name and the brief you wrote, at that link and in the preview image that social networks draw from it. When you list, you give us the same permission for the gallery and for search engines, and permission to show the tour on Prepaper’s own channels (our site, our newsletter and our social media accounts) as an example of what people make, credited to the project name you gave it. This is a licence to show your work, not a transfer of it: it is non-exclusive, free of charge, and you still own everything.

Unpublishing ends that permission for the future. The page stops answering, the link stops working in everyone’s hands, and a listed tour leaves the gallery. It cannot recall copies already made elsewhere, such as a post somebody wrote or an image a network cached, and a copy may remain in our own caches for a short while after. If we have featured a listed tour on our own channels we will take it down when you ask, though a post already made may stay as it was.

By publishing you confirm that you have the right to make the tour public, including anything you uploaded and any names, logos or text in it. Published and listed tours are subject to Acceptable use below. The gallery is curated: we may decline to list a tour or unlist one, for that reason or for an editorial one, and we will tell you when we do. That says nothing about your account.

The brief is shown on the page as text. Do not publish a tour whose brief describes something you are not ready to have read.

10.Acceptable use

Do not use Prepaper to:

  • generate material that is illegal, that sexualises children, or that is designed to harass a specific person
  • infringe someone else at our expense, for example by prompting for a recognisable brand, logo or copyrighted character and shipping the result
  • resell or expose Prepaper generation as your own image-generation service
  • work around the credit system, the free-credit limits, or the rate limits, or automate the product in a way that degrades it for other users
  • probe, scrape or attack the service or the accounts of other users

Generation requests pass through automated moderation, and we may refuse a request that trips it. A refusal tells you what to change; it is not an accusation.

There is a rate limit on generation to keep one account from crowding out everyone else.

11.Third parties in the pipeline

Prepaper does not train or host its own image model. Your brief is sent to a model provider that draws the sets, and their own terms and acceptable-use policies apply to that step. We name who is involved in the privacy policy.

We are responsible for Prepaper. We are not responsible for a model provider changing what it will draw, or for a third-party service you connect the export to.

12.Availability and changes to the service

Prepaper is a young product and we ship changes often. We do not promise a particular uptime, and features may be added, changed or withdrawn.

If we withdraw something you paid for and cannot give you an equivalent, we will refund the unused part of what you paid.

Generative models are not deterministic. The same brief will not produce the same set twice, and we cannot promise a specific artistic result. What we promise is that a set you paid for is delivered or the credits come back.

13.Suspending or closing an account

You can stop using Prepaper at any time and ask us to delete your account. Export anything you want to keep first.

We may suspend or close an account that breaks these terms, that is being used to abuse the free-credit system, or where we are required to by law. Where it is reasonable to do so, we will tell you why and give you a chance to put it right.

If we close your account without cause, we refund the unused part of your current plan period.

14.Our responsibility, and its limits

We provide Prepaper with reasonable care and skill. Beyond that, the service is provided as it is: we do not warrant that it will be uninterrupted, error free, or fit for a particular purpose you have not told us about.

We are not liable for indirect or consequential loss, for lost profits, or for loss of data you had the ability to export and did not.

Where liability cannot be excluded, it is limited to the amount you paid us in the twelve months before the claim.

Nothing here limits liability for fraud, or for anything that cannot lawfully be limited.

15.Changes to these terms

We may update these terms. The date at the top tells you when they last changed.

If a change materially reduces what you get, we will tell subscribers by email before it takes effect, and you can cancel and be refunded for the unused part of your period if you do not accept it.
