Terms and conditions
Last updated 18 October 2026
Storybook is a small service for writing, illustrating, narrating and printing children's stories. These terms are the agreement between you and us, the people who run it (see section 1). By creating an account you agree to them, and by subscribing you agree to them as they stand on the day you subscribe, so please read them first.
1. Who we are
Storybook is run by Double Factorial AB (“we”, “us”), who is also the seller when you subscribe.

2. Your account
You must be at least 18 years old to open one — the stories are for children, but the account is for the grown-up choosing and reading them.
Keep your password to yourself. You are responsible for what is done with your account, and one account is for one person: please don't share it.
3. How stories are made
Stories, pictures and narration are generated by artificial intelligence. To make them, what you type — your story idea and the choices you make — is sent to our AI provider, OpenAI, and processed under their terms. Please don't put anything in a story idea that you would not want shared with them, such as a child's full name together with where they live or go to school.
AI can get things wrong. A story may contain mistakes, a picture may not match its page, and a result may occasionally be odd or unsuitable. Every story is checked against our content standards as it is made, but no check is perfect: please read a story yourself before sharing it with a child.
4. What you may not do
Storybook is for children's stories. You agree not to use it to:
- try to produce sexual, hateful, violent or otherwise harmful content, or anything involving the abuse of a child;
- make stories that harass, mock or impersonate a real person, or that use someone else's private information without their permission;
- copy characters, artwork or text that belong to someone else, or ask for work “in the style of” a living artist in order to pass it off as theirs;
- get around the content checks, the usage allowances, or any other limit, or use scripts or automated tools to drive the service;
- break the law, or interfere with the service or with anyone else's use of it.
The service may refuse a story idea that falls outside these rules or outside what it is for.
5. Your stories
Your story ideas are yours, and so are the stories made from them, as far as the law allows anyone to own AI-generated work. You may keep them, share them and print them for personal, non-commercial use.
You give us permission to store, process and display your stories only so far as we need to in order to run the service for you — keeping them on your shelf, making their pictures and narration, printing the books you order, and reading a story you report to us while we look into it. We do not publish your stories or use them for anything else.
You can download everything you have written, and delete your account and all of your stories, at any time from your account page.
6. Subscription and allowances
Making new stories, pictures and narration needs a subscription, unless we have given your account free access. Reading, listening to, downloading and ordering prints of the stories you have already made never does: they stay yours whether or not you subscribe.
A subscription comes with a monthly allowance of books and pictures. What it contains is shown on your account page before you subscribe, and how much of it is left is shown in the app as you use it.
- Your allowance comes back in full at the start of each month you pay for. What you do not use in a month does not carry over.
- A book is counted once it is finished and on your shelf, with its narration. An idea we turn away, or a story we do not finish or do not publish, is not counted.
- A picture is counted each time a page or cover is drawn or redrawn. Reference sheets we draw to keep characters consistent, and our own second attempts at a picture that did not pass our checks, are not counted.
- To keep the service from being misused, there are also limits on how much writing, narration and drawing one account can cause in a month. They are set well above what making your allowance of books needs; if you reach one, the app says so and when it lifts.
- What has been used stays used: deleting a story does not give its allowance back.
- If a picture or recording fails because of a fault on our side, tell us and we will put back what it used.
- We may make the allowances larger at any time. We will only make them smaller with at least 30 days' notice by email, from the start of a month you pay for, and you can cancel before the change applies to you.
- A subscription is for your account. It cannot be moved to another account, shared, or resold.
How you subscribe:
- On your account page, tick the box agreeing to these terms and to the payment, and press “Start free week, then 49 kr a month” (or “Subscribe for 49 kr a month”, if you have had a free week before). In the Android app, the box and the button show Google Play's price for your country instead (section 8).
- On the website, you are taken to Stripe's payment page, which shows the price and the date of the first payment. Enter your card there. Until you press the button at the bottom of that page you can correct anything you have typed, or go back to Storybook without subscribing, using the back link at the top of the page.
- In the Android app, Google Play's purchase sheet opens instead. It shows the price in your currency and when the first payment is taken, and you pay with a payment method on your Google account. Until you confirm in that sheet you can change the payment method, or close the sheet without subscribing.
- Pressing the button at the bottom of Stripe's page, or confirming in Google Play's sheet, makes the contract. You come back to your account page, which shows your subscription, and we email you a confirmation.
These terms, and the contract, are in English only. We keep a record of which edition of these terms you agreed to and when, and the confirmation email names that edition. This page always shows the latest edition, so save or print a copy if you want one; we will also email you the edition you agreed to if you ask. We have not signed up to any code of conduct.
7. Your free week
- Your first subscription begins with 7 free days, on a smaller allowance that is shown before you subscribe. There is one free week per person: if you subscribe again later, you pay from the start. In the Android app, Google Play also offers the free week only to a Google account that has not had a Storybook subscription before; the button, and Google Play's sheet, say whether it is included before you subscribe.
- You give a card or other payment method when you subscribe, but nothing is charged during the free week. We email you a reminder a few days before it ends.
- Unless you cancel before the free week ends, your subscription carries on by itself, and the first monthly payment is taken at the end of the week.
- If you cancel during the free week, you can go on using it until the week is up, and you pay nothing at all.
8. Price, payment and renewal
On the website, the subscription costs 49 kr a month. In the Android app, Google Play sets the price for the country of your Google account, in that country's currency. Either way, the price is shown on your account page and again on the payment page (in the Android app, Google Play's purchase sheet) before you subscribe, and it is final: it includes any VAT that has to be charged, and nothing is added at checkout. The exception is the United States, and any other country where prices are usually shown before tax: there, Google Play adds any sales tax due where you live at checkout, and its purchase sheet shows the tax and the total before you confirm. If your bank converts the price into another currency, it may charge its own fee for that.
- You pay a month at a time, in advance, on the same day each month as your first payment (or the last day of a shorter month). Your subscription renews each month until you cancel.
- Payments are handled by our payment provider, Stripe, when you subscribe on the website. In the Android app, Google Play sells the subscription on our behalf, as our agent: it takes the payment, its name is on your receipt, and the payment is also covered by Google Play's own terms, but the subscription is with us, under these terms. Your card details go to Stripe or Google and never reach us; we learn only that you paid, how much, and, from Stripe, the email address your receipts go to. Each sends a receipt for each payment.
- If a payment does not go through, Stripe tries your card again over the following days. Until it succeeds you cannot make new books, and you can update your card from your account page at any time. If you subscribed through Google Play, Google Play tries again instead: you can go on making books for the first 7 days while it does, then new books are paused until the payment goes through, and you update your payment method in the Play Store. Either way, if the payment cannot be collected, the subscription ends.
- We may change the price. We will email you at least 30 days before a new price applies to you, and it applies only from a payment date after that; you can cancel before then. A change never affects a month you have already paid for. If you subscribed through Google Play, Google Play tells you about a higher price as well, and usually asks you to accept it: if it asks and you do not, your subscription ends on the day the higher price would first have been charged, instead of renewing.
9. Cancelling
- You can cancel at any time on your account page, in two clicks, without giving a reason, or in the Play Store if you subscribed through Google Play. We email you to confirm.
- Cancelling stops your subscription renewing. It carries on to the end of the free week or month you are in — you keep your allowance until then — and nothing more is charged.
- We do not refund the rest of a month you have cancelled, except under section 10 or section 11.
- Changed your mind? You can keep your subscription from your account page at any time before it ends (from the Play Store, if you subscribed through Google Play).
- Deleting your account ends your subscription at once, and nothing more is charged. One bought through Google Play goes on being listed in the Play Store until the end of the free week or month you were in, but it will not renew.
10. Your right of withdrawal
If you are a consumer, you can withdraw from your subscription within 14 days of subscribing, without giving a reason. Because your subscription — and your free week — starts as soon as you subscribe, before subscribing you are asked to tick a box that says:
“I ask for my subscription to start straight away, during the 14 days in which I can still withdraw from it.”
- To withdraw, use Withdraw from contract here on your account page. It shows your name, the subscription and the email address the receipt will go to; check them, then send it with Confirm withdrawal here. Or tell us by email (section 1): a clear statement that you are withdrawing is enough. You may use the model withdrawal form at the end of these terms, but you do not have to.
- We email you a receipt straight away, saying what we received and when.
- Withdrawing ends your subscription on that day. We refund everything you have paid for it, in full, to the payment method you used, within 14 days of hearing from you — you pay nothing for the days you had.
- The 14 days are counted from the day after you subscribe, and end at midnight, Swedish time, at the end of the fourteenth day. If that day is a Saturday, Sunday or public holiday, they end at the end of the next working day instead. The free week does not move them, and your account page shows the last day.
11. Refunds and problems
- Something went wrong. If the service does not work as described, tell us and we will put it right — by fixing the problem, putting back what it used, or refunding some or all of what you paid for that month. This is on top of your rights under consumer law, which nothing in these terms takes away.
- How refunds are paid. To the card or payment method you used, through Stripe or Google Play, whichever you paid through, within 14 days of our agreeing to it. If you paid through Google Play, you can also ask Google Play for a refund, under its own refund policy.
- Disputed payments. Please talk to us before asking your bank to reverse a payment. If a payment is reversed, we may end the subscription it paid for.
12. Printed books
Asking for a printed book sends us a request; it is not a purchase. Nothing is printed, and you are not charged anything, until we have written to you with the price (including VAT and delivery) and when it will arrive, and you have agreed to them. We may decline a print request.
A printed book is made to order from your own story, so once you have agreed to an order there is no right of withdrawal for it. If a book arrives faulty or damaged, your rights under consumer law apply as usual.
13. Changes, suspension and ending
Storybook is a small service, and we keep improving it. We may change how it works — to fix problems, keep it secure, follow the law, or because a provider we rely on changes what it offers — and a change never costs you anything extra. If a change makes the service noticeably worse for you, we will email you about it in good time before it happens, and you can then end your subscription within 30 days of the change and have back what you paid for the rest of that month.
The service may be unavailable from time to time, and it may one day come to an end. If we plan to close it, we will tell you in good time so you can download your stories first.
We may suspend or close an account that breaks these terms. You can stop using the service and delete your account whenever you like.
If we close Storybook, or end your subscription for any reason other than a serious breach of these terms, we will refund the part of the month you have paid for and not had.
14. Your information and payments
We keep your name, email address, stories and a record of what you have generated and of your subscription, in order to run the service for you. Card details are held by Stripe, or by Google if you pay through Google Play, not by us. Records of payments are kept for as long as bookkeeping law requires — seven years in Sweden — even if you delete your account. How your information is used, who else sees it and what you can ask us to do about it is in our privacy policy.
15. Responsibility
We work hard to make Storybook good and safe, but we cannot promise it will always be available, error-free, or suitable for a particular purpose. As far as the law allows, we are not liable for any indirect loss, or for loss arising from generated content you choose to use or share. Nothing in these terms limits any right you have that cannot be limited by law.
16. Complaints and disputes
If something is wrong, please tell us first (section 1) and we will try to put it right.
If we cannot settle a complaint together and you live in Sweden, you can take it to the National Board for Consumer Disputes (Allmänna reklamationsnämnden, arn.se). If you live elsewhere in the EU, Konsument Europa (konsumenteuropa.se), the European Consumer Centre in Sweden, can advise you for free.
These terms are governed by Swedish law. If you live in another country, you also keep the protection of the consumer laws there that cannot be set aside by agreement, and you can bring a claim in the courts where you live.
17. Changes to these terms
We may update these terms. The date at the top shows when they last changed, and if a change matters we will let you know before it applies — for a change to your subscription, at least 30 days before — and you can cancel before it does. If you keep using Storybook after that, you are agreeing to the new version. A change never alters a month you have already paid for.
