1. Who we are, and these terms

These terms are an agreement between you and Salt and Code (솔트앤코드), a sole proprietorship registered in the Republic of Korea (business registration 373-24-02334; representative Junsu Lee (이준수); B1 4-S9, 306 Apgujeong-ro, Gangnam-gu, Seoul, Republic of Korea) — “we”, “us”. They cover the website at prefigure.net and the Prefigure connector used from AI assistants such as Claude (together, “Prefigure”). Our Privacy Policy and Refund Policy are part of them.

You accept these terms when you tick the box at sign-in or otherwise use Prefigure. If you use Prefigure for a company or other organization, you accept them for it and confirm that you may.

2. What Prefigure is — and is not

Prefigure runs a population of simulated people through a product you are building — screens, a prototype, an app or a website — and reports how many reach what they came for, where the others stop, why, and which change to try first. Simulated people are built from how people in your target groups typically behave, as AI models (see section 6) describe it from your product and its market; their behavior is produced by AI models and by rules we wrote. Some simulations also draw on short excerpts of public posts, which their reports then show with their source (section 5). Some results are also checked by AI models from two different companies.

• A simulation is not a measurement of real users and not a forecast. Numbers in a report describe the simulated people. They can be wrong, sometimes by a lot — in particular, how large an effect will be is less reliable than which way it goes.
• Use Prefigure to find problems early and to compare versions. Do not make it the only basis for business, financial, legal, medical or safety decisions; check what matters with real people.
• The simulated people are fictional. Any resemblance of a simulated person to a real one is a coincidence.

3. Your account and connections

• You sign in with a Google account — or, for an app that cannot sign in, make a private address on the set-up page, which works without signing in. Either way you must be at least 14 years old, and old enough to make a binding agreement where you live (or have your guardian’s consent).
• Your account has a workspace: your simulations, credits and connections. You are responsible for what happens in it.
• A connection lets an AI assistant (such as Claude) use Prefigure for your workspace. Anyone who controls a connection can run simulations on your credits — keep connection addresses private, and remove a connection you no longer use from My space.
• Tell us at once by email at support@saltandcode.net if you think someone else has access to your account or a connection.

4. Your content

• You keep all rights to what you hand over — screens, images, text, flows, product and audience descriptions, the answers to the test plan and the outcomes you report (“your content”).
• You give us a limited, non-exclusive, worldwide, royalty-free permission to store, copy and process your content only to run your simulations, show you and the people you share with the reports, keep the service secure and working, and meet the law. It ends when your content is deleted, except for copies the law requires us to keep and backups that expire on their own (see the Privacy Policy).
• We do not use your content to train AI models, and our AI providers may not either. We do not sell it or share it with anyone except the providers that run Prefigure for us.
• We may use statistics from simulations and the real outcomes you choose to report — combined, without your content and without saying which product they came from — to measure and improve how accurate Prefigure is.
• You confirm that you have the right to hand over your content, and that doing so breaks no one’s rights or confidentiality. Do not hand over other people’s personal information beyond what appears on an ordinary product screen, and never special categories of personal information (health, beliefs and the like) about real people.
• Screen images are deleted 30 days after they are handed over. Everything else stays until you delete it or your account.
• Reports are shared by link. Anyone with a report’s address can open it, unless you make it private. Share links with care.
• We do not look at your content except when you ask for help, to look into a failure or abuse, or when the law requires it — and then only the person responsible for Prefigure, and only as much as needed.

5. Reports and what the AI writes

• As between you and us, the reports and everything written for your simulations are yours to use as you wish, as far as the law allows.
• AI-written text can be wrong, incomplete, or similar to what is written for others. Check it before relying on it.
• Some reports — those whose simulated people also drew on public posts — show quotes as “what real people wrote online”: short excerpts of public posts, with their source, used to explain who the simulated people stand for. Their authors own them; do not republish them as your own.
• We keep a sealed copy of each report’s prediction so that, if you tell us what really happened, the prediction can be scored honestly. That copy is part of your simulation and is deleted with it.

6. AI providers

Prefigure sends your content to AI models run by Anthropic (Claude) and Google (Gemini) to read screens, describe the audience’s groups, play the simulated people, check results and write reports — on their paid business services, under terms that do not let them train on it. The Privacy Policy lists every provider, what each receives and where. When you use Prefigure from your own AI assistant, what you and your assistant say to each other is between you and that assistant’s provider; we receive only what the assistant sends to Prefigure.

7. Credits, plans and prices

• Running a simulation uses credits. Its price depends on how many screens are read for the first time and whether two versions are compared; it is shown before anything runs (the pricing page has the list).
• A simulation that fails, or that cannot use the AI models or read most of the screens and falls back to built-in rules, gives its credits back automatically.
• Your first simulation is free. A workspace without a plan may run one simulation without credits: the first visit, of up to 10 screens, with 300 simulated people, while the day’s free capacity lasts. Its report shows where people get to and where most leave; the rest of the report — why they leave and what to change first — opens with a plan. One free run per workspace and per product: the same product (the same web address or the same pictures) does not run free again under another connection, and using several connections or accounts to get more free runs is getting around our limits. If it fails, it is free again.
• A new workspace starts with no credits. Starter and Pro add their monthly credits with each paid month; a credit pack adds credits once. Unused credits stay in your workspace while your account exists. Credits have no cash value and cannot be transferred, sold or exchanged for money, except as our Refund Policy provides.
• Plans set the size of a simulation (people and simulated days), and comparing two versions is part of Pro. Without a plan, credits you bought run at Starter’s size, one version at a time. To protect the service, simulations may pause for the rest of a calendar month when overall capacity is used; nothing is charged for a simulation that does not run.
• We may change prices, plans and how many credits something uses. Changes apply to what you buy or run after they are published. A subscriber keeps the price of their plan for as long as they stay subscribed; any other change to a subscription you already have applies from a billing period that starts at least 30 days after we tell you.

8. Payments, renewal and refunds

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Paddle’s buyer terms also apply to your purchase. Prices are in US dollars (or Korean won where offered); Paddle adds the sales tax or VAT that applies where you are.

• Starter and Pro renew every month and are charged automatically until you cancel. Cancel any time from My space (Manage billing): your plan stays on until the end of the month you paid for, and your credits stay.
• Moving from Starter to Pro takes effect at once: the difference for the rest of the month is charged then, and Pro’s extra credits for the rest of that month are added (the whole month’s difference in credits, in proportion to the days left). To move from Pro to Starter, cancel Pro and choose Starter when it ends.
• Refunds: within 14 days of a payment you get back the share you have not used, with no reason needed — see the Refund Policy. Nothing in these terms takes away refund or withdrawal rights the law of your country gives you.

9. Acceptable use

Do not use Prefigure to:

• break the law or anyone’s rights, including intellectual property, privacy and confidentiality;
• hand over content you have no right to, or content that is illegal, hateful, sexually exploitative or meant to harm;
• test products whose purpose is to defraud, manipulate or harm people, or to design ways around people’s consent;
• attack, overload, probe, scrape or reverse-engineer the service, or get around its limits, credits or security;
• use its output to build or train a competing service or AI model;
• pretend that simulated people or results are real users or real data, toward anyone.

We may remove content, pause simulations or suspend a workspace that breaks this section — after telling you why where we can (section 14).

10. Our service and our rights in it

Prefigure — its software, engine, designs, texts and the name and owl mark — belongs to us and our licensors. These terms give you the right to use it as offered, nothing more. If you send us ideas or feedback, we may use them freely and without any duty to you.

11. Changes, interruptions and ending the service

We work to keep Prefigure available and correct, and to improve it. We may change, add or remove features, AI models and providers; when a change of provider changes where your information goes, the Privacy Policy says so first. The service can be interrupted for maintenance, failures or reasons outside our control. If we stop Prefigure entirely, we will tell you at least 30 days before, give you that time to save your reports, and refund unused paid credits in proportion.

12. Disclaimers

To the extent the law allows, Prefigure is provided “as is” and “as available”: we do not promise that a simulation matches what real people will do, that a change it suggests will work, or that the service will be uninterrupted or error-free. This does not limit anything the law does not let us limit, including your rights as a consumer.

13. Limits of liability

To the extent the law allows, we are not liable for indirect, incidental, special or consequential losses, lost profits, revenue, data or opportunities, or decisions made from a simulation. Our total liability for all claims in connection with Prefigure is limited to the greater of what you paid us in the 12 months before the claim and 100 US dollars. These limits do not apply to losses we cause on purpose or by gross negligence, to death or personal injury, or where the law does not allow them.

If you use Prefigure for a business, you will make good any loss we suffer from a claim by someone else caused by your content or by your breaking these terms.

14. Suspension and ending

• You can stop at any time and ask us to delete your account and everything in it (by email at support@saltandcode.net). Unused credits from payments older than 14 days are not refunded on deletion, except as the law requires.
• We may suspend or end your access if you seriously or repeatedly break these terms, if the law requires it, or to protect others or the service. Where we can, we tell you first and give you the chance to fix it and to take a copy of your reports.
• Sections 4 (your rights in your content), 5, 10, 12, 13, 16 and 17 survive the end of these terms.

15. Changes to these terms

We may update these terms. We will post the new text here with its date and, for changes that matter to you, tell you by email or in My space at least 7 days before they apply (30 days if a change is against your interests). If you do not agree, stop using Prefigure before the date; your Refund Policy rights still apply.

16. Law and disputes

These terms are governed by the laws of the Republic of Korea. Please write to us first (by email at support@saltandcode.net) — most problems are solved there. Disputes go to the Seoul Central District Court, unless the law where you live as a consumer gives you the right to bring them to your local courts or authorities.

17. The rest

• These terms, the Privacy Policy and the Refund Policy are the whole agreement between you and us about Prefigure.
• If part of them cannot be enforced, the rest still applies. Not enforcing a part at once is not giving it up.
• You may not transfer these terms; we may transfer them to whoever takes over Prefigure, and will tell you.
• These terms are also published in Korean. If the two differ, the English text prevails, except where the law of your country requires otherwise.
