Terms
Last updated 23 August 2026
What you are buying, who from, and what each of us is agreeing to do.
You buy a season of Conundrum Curriculum — eight weeks of material for a child aged roughly 8 to 11, delivered on this website and run at home by you. There is no live teaching and no class to attend.
Your purchase contract is with Paddle.com Market Ltd, which is the merchant of record. The material is provided by Chen-kuo Chou (ABN 12 167 336 639). Both of those matter and both are explained below.
Who you are dealing with
Paddle.com Market Ltd is the merchant of record: the legal seller for the transaction. It runs the checkout, takes the payment, handles sales tax and appears on your card statement. Paddle’s own terms apply to the payment itself.
Chen-kuo Chou (ABN 12 167 336 639) — a sole trader in South Australia, Australia — writes and supplies the material, runs this website and answers your email.
In practice: ask Paddle about a charge, and ask us about the curriculum. Either of us can start a refund — see the refunds page.
What you are buying
A season is eight weeks of material. Each week has three to five short concept sessions, two conundrums, and one step of a physical project, together with a word-for-word script for the parent running it.
One season — US$99 (USD), a one-time purchase. Nothing recurs and nothing renews by itself.
One year — US$390 (USD), a subscription billed yearly. It covers 5 seasons, 40 weeks of material, with breaks between seasons. It renews once a year until you cancel.
There is no monthly plan, deliberately. A month does not divide into an eight-week season, and the point at which a monthly plan would end is the middle of a three-week project.
The first 100 families pay half price on either of those, on the terms set out on the refunds page.
Prices are in US dollars. What Paddle charges you may include sales tax or VAT depending on where you are, and Paddle shows that before you pay.
When you get it
As soon as your payment goes through: Week 0, and any past season that is already finished. You can work through those whenever you like and repeat them.
The season you bought unlocks one week at a time, starting on that season’s published start date. Seats can be bought before that date; the material does not appear before it.
Once a week has unlocked it stays available to you for as long as your access lasts.
Seasons run as cohorts on fixed dates, and there are gaps between them — a year is five seasons, not fifty-two weeks of material. The gaps are on purpose: they keep a season clear of the holidays.
Your account
The only account is a parent’s, and the only credential is an email address.
There are no accounts for children and no fields for a child’s personal information. A child is referred to by whatever name you type.
One account is for one family. Sharing your login outside your household is the one thing here that will get access withdrawn.
What you may do with the material
You get a personal, non-transferable right to use the material with the children in your own household, for as long as your access lasts.
Print it, write on it, take it to the kitchen table. That is what it is for.
Do not republish it, sell it, put it in a course, or use it to teach a class, a co-op or a school group. A version for teachers may exist one day; this is not it.
Do not use the material to train a machine-learning model.
What your child makes is your child’s: the writing, the recordings, the objects, the photographs. We claim nothing in it and we do not publish it.
What we do not promise
We do not promise exam results, grades or test scores, and we make no claim about them. This is not exam preparation and it is not designed to be measured that way.
There is no live teaching, no tutor and no marking. You run the activities. The material tells you exactly what to say, but the adult in the room is you.
We do not supervise your child, and nothing here substitutes for your judgement about what your child is ready for.
We do not promise that any particular activity will suit every child in the age range. Difficulty tiers exist for that reason, and skipping something is a legitimate use of the product.
Safety, and activities that involve other people
Projects use ordinary household materials, and some involve scissors, string, tape or a walk down a hallway. You decide what your child does unsupervised.
Some activities ask a child to talk to a real person — to explain something, to ask a question, to teach someone. Every one of those is arranged by you, from your own contacts, with you present. This product introduces no one to anyone, has no messaging, and has no way for one family to reach another.
Using AI
Activities state which of three levels of AI use applies: none, ask-then-justify, or collaborate. That is guidance for you to run, not something the software enforces, and it is a teaching design rather than a rule about right and wrong.
Where the product itself uses a model to generate follow-up questions about your child's work, it runs on our servers and the privacy page describes what is sent.
Changes
We improve the material between cohorts. A season you have already been through may read differently later.
If a start date has to move, we will tell you before the season begins.
We will not change the price of something you have already bought. A price applies from when it is published; a yearly subscription keeps the price it started on until you cancel it.
If we change these terms, the date at the top changes. Material changes will be emailed to anyone with an active purchase.
Ending it
You can stop at any time. A season is a one-time purchase, so stopping is simply not buying the next one; a yearly subscription is cancelled from your account or through Paddle.
Refunds are on their own page, and the promise there is part of these terms.
We can end access for sharing a login outside your household, for republishing the material, or for abusing the people who answer the email. We would write to you first in anything short of the last.
Liability
Nothing here excludes rights you have under consumer law — in Australia that means the consumer guarantees under the Australian Consumer Law, and elsewhere it means whatever your local law gives you, which we are not trying to contract out of.
Beyond those rights, our liability for anything connected with this product is limited to what you paid for it. We are not liable for indirect or consequential loss.
These terms are governed by the law of South Australia, Australia.
