Terms of Service
Version 1.1 · prepared 13 August 2026 · effective when published
Orientation only — this box is not part of the agreement.
You see a real chapter and a real illustrated page of your child's book before you pay anything. A book is then a one-time purchase. The finished book, its print-ready file and every copy you download are yours permanently — no membership can take them away, and we do not build anything that could. Every picture and chapter comes with three attempts; more are €5 for the whole book. We write and paint with AI, openly, and nothing enters your book that you have not approved. You must have the right to every photograph and story you upload — that is the one obligation we cannot soften, because it concerns other people's children. If something we sold you is broken, you have full statutory rights and we would rather just fix it.
Where this box and the clauses below differ, the clauses below govern (§§1–23).
1.1 In these Terms:
1.2 Headings are for navigation and do not affect interpretation. References to a "§" are to a clause of these Terms.
2.1 These Terms govern your use of the Service and every contract you conclude with us through it. By creating an Account or making a purchase you accept them.
2.2 Martym turns a family's own story into an illustrated book. You supply the story and the decisions; the Service drafts prose, paints illustrations, assembles the pages, and can narrate the result.
2.3 The Service uses artificial intelligence, and we say so plainly. Chapter text, illustrations, translations and narration are generated by automated models operated by us and by third-party providers. You direct the work and you approve each result; nothing is placed into a finished book without a decision by you. Books carry a statement of AI provenance in their imprint.
2.4 Because the models are probabilistic, output varies between runs and cannot be specified exactly in advance. §6 (attempts), §7.4 (taste and conformity) and §10.6 (rights in generated material) describe the consequences of this, and you should read them before you buy.
2.5 The Service is family entertainment and storytelling. It is not medical, psychological, therapeutic, diagnostic or educational advice or treatment, and it must not be relied upon as any of those. Where our marketing describes what a story can help a child rehearse — courage at night, a first day at school, a hospital visit — that is a description of storytelling, not a clinical claim about your child, and it does not replace advice from a qualified professional.
2.6 You decide what is suitable for your own child. The Service gives you approval over every chapter and every picture for exactly that reason. Generated drafts may occasionally be unexpected or unsuitable; that is why they are drafts, and why the decision is yours.
2.7 AI transparency. We disclose AI generation in three places: in the Service while you work, in these Terms, and in the imprint of every finished book. We do not present AI-generated material as human-authored anywhere, and we do not generate content designed to depict a real, identifiable person as doing or saying something they did not do or say. Where Regulation (EU) 2024/1689 (the AI Act) requires synthetic content to additionally carry a machine-readable marking, we will apply it.
3.1 You must be at least 18 years old and have full legal capacity to conclude a contract with us. The Service is not offered to children, and children must not create Accounts. A child may of course be read to, and may be the hero of the book.
3.2 An Account is created through a passwordless link sent to your email address or a supported external sign-in provider where enabled. We do not store a password for your Account. One Account represents one family or household.
3.3 You are responsible for keeping access to your Account secure, for everything done through it, and for every person to whom you give access. Tell us promptly if you believe your Account has been compromised.
3.4 Devices may be linked to your Account for reading. A linked device receives read-only access to your family's own shelf; it can never author, purchase or delete. You may revoke any device at any time, and signing out everywhere revokes all of them.
3.5 You may not sell, rent, share or transfer your Account or access to it outside your household, use the Service through automated means, scrape it, attempt to circumvent its limits or metering, or reverse engineer it except to the extent that such a restriction is void under mandatory law.
4.1 Before any payment we offer a first look: the first chapter written with you, your child painted to match the reference photographs you gave us, and one real illustrated page.
4.2 An Account is required for the first look. Creating one starts the 30-day Basic Trial described in §14a. The first look is free of charge, requires no card, never converts automatically to a paid service, and creates no payment obligation of any kind.
4.3 Our public promise — "if the first look doesn't melt you, you owe nothing at all" — means precisely this: you are never charged before you have seen the first look. It is a promise about the order of events, not a post-purchase money-back entitlement. It does not limit your statutory rights under §§7–9.
4.4 Material shown in a first look may be watermarked or reduced in resolution until purchase.
4.5 The first look is offered per family, in a reasonable quantity, so that it remains free for everyone. We may decline or limit free generation where we have reasonable grounds to believe it is being used to obtain the paid product without paying, to resell output, or to circumvent this clause through multiple Accounts.
5.1 A Book is a one-time purchase, priced by Book Shape. There is no subscription required to make or to keep a book. Buying a Book Shape entitles you to make one Book of up to the number of chapters published for that shape, and includes the attempts described in §6, the assembled book and the print-ready file. Buying a Book does not extend the Trial or Membership shelf period.
5.2 The following are separate, separately-priced items: narration (voice) for a Book; additional attempts (§6.4); a translated edition of a finished Book; and the Membership. The current price of every item is published on our pricing page and shown again before you confirm payment.
5.3 Prices are stated in euro (EUR). The price shown before you confirm is the price you pay. VAT is applied according to your country of residence and is shown at checkout. We will issue a VAT invoice on request.
5.4 Payment is processed by Stripe. We do not receive or store your card details. A purchase takes effect when our payment provider confirms it; a confirmation displayed in your browser before that confirmation arrives is provisional and is marked as such.
5.5 Where a discount is offered (for example for a further book in a world you have already built), it applies as described at the point of sale and cannot be combined with another discount unless we say so.
5.6 We may change our prices at any time. A change never affects a purchase already made, and for the Membership it takes effect only from the next renewal after we have notified you (§14.7).
5.7 Purchases are tied to your Account. Attempts and translated editions are not transferable between Accounts, have no cash value, and cannot be exchanged or redeemed for money.
5.8 If a payment is reversed or charged back, we may suspend paid functions of the Account until the position is resolved. §18.5 (what you keep) applies regardless.
5.9 Price reductions. Where we announce a price reduction, we also state the lowest price we charged for that item in the 30 days before the reduction, as required by law. A structural discount that is part of the offer itself — for example a reduced price for a further book set in a world you have already built — is not a price-reduction announcement and is stated as what it is.
5.10 Customer reviews, if and when we show any. We publish no invented, bought or incentivised reviews, and we do not publish a review as genuine unless we have taken reasonable steps to verify that it comes from a customer who actually made a book. Where we display reviews we state next to them how they are collected and verified. We do not suppress unfavourable reviews to raise an average.
5.11 We do not personalise prices to an individual using automated profiling. Everyone sees the same published price for the same item, subject only to VAT by country and any discount stated openly at the point of sale.
5.12 When you get it. Everything you buy is supplied immediately once payment is confirmed — access to the paid stage of the Service opens at once, and each Deliverable appears in your Account as it is generated (§7.1). There is no dispatch and no waiting for post.
5.13 We ask for no deposit and no financial guarantee of any kind, at any point.
6.1 Generating a chapter, a picture, a translation or narration consumes real computing resources that we pay for. Each paid point in the Service therefore carries three attempts: the first making and two redos.
6.2 Two rules are in your favour, and we state them contractually:
6.3 Attempts are counted per item and per Book, automatically. The Service shows you how many remain before you spend one.
6.4 If you want to keep exploring past the included three, you can buy a pocket of additional attempts for the whole Book at the price published on our pricing page. A pocket is scoped to the Book you bought it for, does not expire, and is subject to §5.7.
6.5 Some operations draw more than one attempt from a pocket where they perform more than one generation; the Service states the draw before you confirm.
6.6 Attempts are a mechanism for creative preference, not a remedy for defects. If something we supplied is genuinely not as described, §7 applies and exercising rights under §7 costs you nothing.
7.1 The Service is supplied as digital content and digital services. Delivery happens continuously as you work: each Deliverable is made available in your Account when it is generated and approved, and the print-ready file is made available when you build it. We do not ship physical goods and we do not print books.
7.2 We owe you conformity with the contract under Chapter 5b of the Consumer Rights Act (implementing Directive (EU) 2019/770). Where a Deliverable or the Service does not conform, you may require us to bring it into conformity; and where we fail to do so, refuse to, or the non-conformity is material, you may demand a proportionate price reduction or withdraw from the contract, on the statutory terms. Nothing in these Terms excludes or limits those rights.
7.3 Conformity is measured against what we described and what you bought: the Book Shape's chapter maximum, the illustrations you approved being present, the assembled book being readable, the print-ready file being produced to the stated specification, purchased narration existing for the chapters it was bought for, and the Service being fit for the purpose for which such a service is ordinarily used.
7.4 A creative outcome you do not like is not a lack of conformity. Prose style, a picture's composition, a colour, a likeness you find imperfect or a voice you would have cast differently are matters of taste, and taste cannot be specified in a contract. Your remedies for taste are the free first look (§4), which exists so that you judge before you pay, and the attempts (§6), which exist so that you can keep trying. This clause allocates taste to those mechanisms; it does not restrict your statutory rights where something is genuinely not as described.
7.5 We will supply updates, including security updates, necessary to keep the Service in conformity for as long as is required by law. Functional changes are governed by §17.
7.6 Our records of what the Service generated, when, and for which Account — including the attempt ledger — may be relied upon as evidence of what was supplied. You remain free to prove the contrary by any means.
7.7 Technical requirements. To make a book you need a device with a current version of a mainstream web browser and a working internet connection. To read a book you need the Reader in a browser, or the Martym Reader app on a supported device. To use the print-ready file you need a PDF reader, and to have it printed you need a printer or print shop that accepts a print-ready PDF. Uploading reference images requires common image formats (JPEG, PNG). Narration is delivered as standard audio files.
7.8 Formats and interoperability. The print-ready file is a standard press-ready PDF. Downloaded books and audio use standard, widely readable formats. We do not use proprietary formats that would lock your book to us.
7.9 No technical protection measures. We apply no DRM and no copy protection to the book, the print-ready file or the narration audio. There is no licence check, no activation and no phone-home. This is deliberate, and it is what makes the guarantee in §18.5 mean something. The only technical measure we use is a watermark on pre-purchase first-look material (§4.4).
7.10 Cost of communicating with us. Using the Service costs you nothing beyond your own internet access, charged by your own provider at your own rates. We operate no premium-rate numbers and charge nothing for contacting us.
7.11 So that you know this before you buy rather than after: generated illustrations sometimes distort faces, hands, teeth and small details; a likeness can drift between pictures; and text drawn inside a picture is never reliable, which is why every word in your book is typeset by us instead. Your child will be recognisable and consistent across the book — that is the product, and it is the hard part we solved — but a painted likeness is an interpretation, not a photograph. "It is not exactly my child's face" is therefore a matter for §7.4 and for your attempts under §6, not a defect. We would rather say this plainly here than have you discover it at the end of an evening.
7.12 We are liable for a lack of conformity that existed when we delivered and that comes to light within two years of delivery; for anything supplied continuously, for the whole period of supply. A lack of conformity that shows up within the first year is presumed to have existed at delivery, so you do not have to prove that it did — we have to prove that it did not. And where you are entitled to withdraw for non-conformity, the non-conformity is presumed to be significant: it is on us to show it was trivial, not on you to show it was serious.
7.13 That presumption does not apply where the problem is caused by your own device or software being incompatible with the technical requirements in §7.7, which we told you about before you bought. We will ask you to help us work out which it is before either of us concludes anything.
8.1 If you are a Consumer, you have a statutory right to withdraw from a distance contract within 14 days of concluding it, without giving a reason. To withdraw, tell us — an email to the complaints address above is enough. You may use the form in Annex 1, but you do not have to. We will confirm receipt and refund you, using the same means of payment, within 14 days.
8.2 The statutory exception. Our product is digital content made to your order and delivered immediately, because that is the point of it. Under art. 38(1)(13) of the Consumer Rights Act, you lose the right of withdrawal once we have fully delivered the digital content, provided that before delivery you expressly consented to us beginning delivery, and acknowledged that you would thereby lose the right of withdrawal, and we confirmed that to you.
8.3 We may rely on that exception only after checkout has asked for your separate, express consent to immediate delivery, recorded your acknowledgement that the right will be lost upon full delivery, and sent confirmation on a durable medium. The current checkout does not collect that complete consent, so we do not rely on the exception: your statutory withdrawal right remains. We will update the checkout and these Terms before relying on the exception.
8.4 For the Membership (a digital service rather than content): if you ask us to begin before the 14 days expire and then withdraw, you owe a proportionate amount for the period actually supplied, in accordance with art. 35 of the Consumer Rights Act. Otherwise you owe nothing.
8.5 The free first look involves no payment, so §8 does not apply to it; you may stop, or delete your Account, at any moment (§18.2).
8.6 Where you withdraw effectively, we may prevent further use of the withdrawn Deliverables, and you must stop using them; the guarantee in §18.5 does not extend to material for which you have received a refund.
8.7 You get your own material back. If you withdraw, or if a contract ends for any other reason, then on your request and at our cost we will make available to you, within a reasonable time and in a commonly used machine-readable format, the content other than personal data that you provided or created using the Service — your manuscripts, your answers, your uploads and your approved chapter text. We will not otherwise use that content after the contract ends, except as §10.2 permits while we still hold it. Personal data is handled under our privacy policy and your rights there are wider still.
8.8 You may withdraw by sending any clear statement to hello@martym.com; the Annex is optional. We acknowledge receipt on a durable medium. If we add an electronic withdrawal function to the Account, it will be an additional route and never the only one.
8.9 Where you withdraw, we do not charge you for any period during which what we supplied was not as described, and we refund the part of the price attributable to what was not delivered or was not conforming.
9.1 Send complaints to the complaints address in the identity block above. Please describe what happened, what you expected, and which Book it concerns — it makes a real fix faster.
9.2 We will respond to a Consumer complaint within 14 days of receiving it. If we do not respond within that period, the complaint is deemed accepted as submitted.
9.3 A Consumer may use out-of-court dispute resolution. In Poland these routes include the permanent consumer arbitration courts and the mediation services of the Trade Inspection (Inspekcja Handlowa), the municipal or district consumer ombudsman (rzecznik konsumentów), and the information services of the Office of Competition and Consumer Protection (UOKiK), which maintains a register of entities competent to resolve consumer disputes out of court. Using these routes is voluntary for both sides.
9.4 A Consumer resident elsewhere in the EU can find their national body through the European Commission's Consumer Redress in the EU information portal. We deliberately do not point you to the EU "ODR platform": the Regulation behind it was repealed and the platform stopped operating on 20 July 2025, and sending you to a dead service would be worse than saying nothing.
9.5 Nothing here prevents you from going to court.
10.1 You keep every right you already hold in your Input. We claim no ownership of your story, your manuscript, your notes or your photographs.
10.2 You grant us a licence to your Input that is limited to what making and delivering your book actually requires: to store it, process it, display it back to you, transmit it to the providers listed in our privacy policy for the purpose of generating your Deliverables, and keep the backups our systems make. The licence is non-exclusive, royalty-free, worldwide for technical reasons only, and lasts as long as we hold the Input. It ends when you delete the Input or your Account, save for backups pending deletion in the ordinary course and records we must keep by law.
10.3 We do not use your Input, your photographs or your books to train AI models, and we contract with our providers on terms intended to prevent them from doing so. We do not sell your Input and we do not publish it. Reference photographs of children are never published anywhere, in any circumstances.
10.4 On full payment for a Book, we transfer to you, to the fullest extent that such rights exist and are legally transferable, the economic copyright in the Deliverables of that Book — the chapter text, the illustrations, the cover, the assembled book and the print-ready file — without limitation as to territory, time or manner of use (subject to §10.5), including the right to reproduce, print, adapt, translate and distribute copies. Where those rights cannot be transferred, we grant you instead a perpetual, irrevocable, worldwide, royalty-free and sublicensable licence to the same effect, and we undertake not to assert against you any right that would restrict your use of your own book.
10.5 That transfer is for your personal and family use, which expressly includes: reading it, printing it as often as you like at any printer you choose, giving printed or digital copies to family and friends, and keeping it forever. Commercial exploitation — publishing your book for sale, distributing it commercially, or licensing it to others — requires our prior written agreement, which we do not unreasonably withhold and for which we may charge. Nothing in this clause restricts your use of your own pre-existing Input.
10.6 What we cannot promise about AI-generated material, stated openly. The models are probabilistic and are used by many customers:
10.7 Moral rights (author's personal rights) are inalienable under Polish law. To the extent any arise on our side in a Deliverable, we undertake not to exercise them against you and authorise you to make the book public and to alter it.
10.8 The Service itself — the software, the Studio, the Reader, the interfaces, our name, logo, typography, page designs, sample books, prompts and the methods by which we make books — remains ours or our licensors'. Buying a Book gives you the book, not the machinery that made it, and grants no right to our trade marks.
10.9 Sample and demonstration books shown on our website and in the Reading Room remain the property of their owners and may not be copied.
10.10 If you send us suggestions about the Service, we may use them freely and without obligation. We will not treat such suggestions as confidential.
10.11 We never use your book or your family in our marketing unless you opt in. Not by default, not buried in this clause, and never as a condition of any price or discount. If we would like to show a page, a dedication or a quotation, we will ask for that specific thing, you may say no with no consequence, and you may withdraw permission later — after which we stop using it in anything new. A photograph of a child is never used in our marketing, even with permission.
11.1 This is the most important obligation you take on, and we cannot soften it, because it concerns other people and their children. You represent and warrant, for every Input, that:
11.2 Do not upload photographs of a child who is not in your care. Do not build a book about a real person who has not agreed to it. If you are not certain you hold a consent, obtain it first.
11.3 We may refuse, pause, remove or delete any Input or Deliverable where we have reasonable grounds to believe §11.1 is not satisfied, or where a person identifiable in it asks us to and their request appears well founded. Where we can, we will tell you why.
11.4 If you are a Consumer, you are liable for loss you cause us by breaching §11.1 on general principles of civil liability (art. 471 of the Civil Code); nothing in these Terms imposes on you a liability broader than the law provides. If you are not a Consumer, §22.4 applies instead.
12.1 You must not use the Service to create, request, store or publish:
12.2 You must not attempt to defeat the Service's safety measures, prompt it into producing prohibited material, or use it to generate material for someone else who intends any of the above.
12.3 Consequences. Breach of §12.1 entitles us to remove the material and to suspend or terminate your Account immediately and without notice. In the case of the first two bullets of §12.1 we will do so, we will preserve the material and the associated records for as long as that purpose requires, and we will report the matter to law enforcement or the competent authority where the law requires or permits it. No refund is due for an Account terminated under this clause, and the guarantee in §18.5 does not apply to unlawful material.
12.4 We are not obliged to monitor Inputs generally and we do not do so; we act on what we detect and on what is reported to us.
13.1 Publishing is always a separate, explicit choice, made for each Book, and nothing is ever published by default or by inaction. Before a Book is published we ask you, in plain words on the control itself, who will be able to read it. Which answers are available to you depends on your Membership (§14): with Premium you may keep a Book to your Account or publish it to the Reading Room; with Basic, a Book you publish goes to the Reading Room, and we say so on the button before you press it.
13.1a Nothing you did not do publishes a Book. A Membership that lapses, a payment that fails, a change of tier and the end of a free trial never publish a Book that was not published, and never change who can read one that was. If you move from Premium to Basic, a Book you kept to your Account stays unpublished (§14.9).
13.1b Reading the Reading Room requires a Membership; putting a Book into it does not. Publishing is free at either tier, and nothing about your own Books depends on anyone else paying.
13.2 If you publish, you grant us a non-exclusive, royalty-free, worldwide licence to host, store, reproduce, display and transmit that Book so that it can be read by others through the Service, and to show its cover and title in listings. The licence lasts while the Book is published and ends within a reasonable time after you unpublish it, save for copies already lawfully downloaded by readers and our backups pending deletion.
13.3 You may unpublish at any time. Reference photographs are never part of a published Book, and we do not publish anything else from your Account.
13.4 Before publishing, consider carefully what a published book reveals about a child — a name, a face, a place, a school, a family situation. Publication is optional and nothing in the Service requires it.
13.5 Reporting illegal content. In respect of the Reading Room we act as a hosting service provider. Anyone may notify us of content they consider illegal, at the illegal-content address in the identity block above. A notice should identify the content, explain why it is said to be illegal, and give contact details for the notifier. We will handle notices in a timely, diligent, non-arbitrary manner and inform the notifier of our decision, in accordance with art. 16 of Regulation (EU) 2022/2065 (the Digital Services Act). We may remove or disable content, and suspend a publisher, where a notice is well founded or where content breaches §12.
13.6 If your Book is removed from the Reading Room, you keep the Book itself and everything §18.5 guarantees; removal affects publication only.
13.7 If we restrict something of yours, we tell you why. Where we remove or disable access to content you published, suspend publication, or restrict your Account, we will give you a statement of the reasons — what was restricted, the ground for it, whether a notice or an automated check triggered it, and how to disagree with us — unless the law forbids us from telling you. You may reply to any such decision at the complaints address, and we will look again.
13a.1 With a Premium Membership you may share one of your Books with another Account, by giving us the email address of the person you want to give it to. Sharing is per Book and never automatic.
13a.2 What a share gives is reading. The recipient sees that Book on their own shelf, with its pictures and its narration. A share never gives them the print-ready file, and never lets them edit the Book, publish it, or share it onward.
13a.3 For as long as a share lasts you grant us a non-exclusive, royalty-free licence to host and display that Book to the recipient you named, for that purpose and no other.
13a.4 You may take a share back at any time. Doing so removes the Book from the recipient's shelf. It does not reach a copy they have already downloaded, or a link they have kept — for the same reason your own downloads can never be revoked (§18.5). We say this on the control itself, because a promise we cannot keep would be worse than the limitation.
13a.5 If the address you give has no Account yet, we hold the invitation until an Account is opened with that address and the sign-in provider confirms the address belongs to that person. An address that has not been verified, and a provider's private relay address, never claim an invitation.
13a.6 We record when a shared Book was last opened and show that to you, so you know whether the gift arrived. We show you nothing else about the recipient.
13a.7 Sharing a Book about a child gives another household its contents. §11 applies to sharing exactly as it applies to publishing: share only what you have the right to share, and consider what the Book reveals.
13a.8 Shares end when your Premium Membership ends (§14.9). Ending a share never affects the Book itself, and never affects anything under §18.5.
14.1 The Membership is the only subscription we sell. It comes in two tiers — Basic and Premium — priced per Account, monthly or yearly, as published on our pricing page. There is no per-reader charge and no seat count: one Membership covers your Account and the devices you read on.
14.2 Basic covers the living shelf — reading across devices, reading progress that follows you, child profiles, read-along narration playback, adding new devices, and streaming or synchronising your library from our servers — and reading every Book that other families have published to the Reading Room.
14.3 Premium covers everything in Basic and adds two things: keeping a Book to your Account instead of publishing it (§13.1), and sharing a Book with another Account (§13a).
14.4 What no Membership covers, ever: the ownership of your Books. See §18.5.
14.5 A Book purchase is separate from the Membership. It does not start, renew or extend a Membership period or shelf deadline.
14.6 The Membership renews automatically for successive periods until cancelled. You may cancel at any time, in the Account, with effect at the end of the period already paid for. We do not refund unused parts of a period except where the law requires it.
14.7 We will notify you at least 14 days before any increase in the Membership price or any material reduction in what it covers. The change applies from your next renewal, and if you do not accept it you may cancel before then.
14.8 If the Membership lapses, the shelf rests: the server-side library view and synchronisation stop, and nothing is deleted. Reactivating restores the shelf. Cancelling the Membership never changes anything about the Books you have bought.
14.9 Changing tier. You may move between tiers at any time; an upgrade takes effect immediately and our payment provider adjusts the price for the part of the period remaining. Moving from Premium to Basic never publishes anything. A Book you had kept to your Account stays unpublished — it simply stops being listed on your shelf until you return to Premium, and your downloads and print files are unaffected throughout. Shares you had made end.
14.10 Duration, plainly. The Membership runs for the period you chose — one month or one year — and renews for further periods of the same length until you cancel. There is no minimum term, no notice period and no cancellation fee. Cancelling takes effect at the end of the period already paid for. A Book purchase, by contrast, has no duration at all: it is a single payment for a single book.
14a.1 Every new Account begins with a free Basic Trial lasting 30 days. It includes the shelf and the free first look. No card is required to start it and starting it costs nothing.
14a.2 Nothing renews automatically out of a trial. A trial never turns itself into a paid Membership: it becomes one only if you choose a tier and pay.
14a.3 At the end of the Trial, if you have not started a paid Membership, the shelf rests: its server-side listing and synchronisation stop. Your Account, projects and Books are not deleted, and downloads and print files remain usable.
14a.4 Starting a paid Membership reactivates the shelf for the paid period. Buying a Book does not extend the Trial or the shelf deadline.
14a.5 A Book purchase ends the Trial marker so the Account is no longer described as being on trial. It does not create a Membership or change the existing shelf deadline. The permanent rights in §18.5 apply to every Book you buy.
14a.6 You may download everything you have made at any time during the trial, and we recommend doing so before it ends. §8.7 (getting your own material back) applies to a trial exactly as it applies to a paid contract.
14a.7 The trial is one per person. We may decline a further free trial where an Account appears to have been opened in order to obtain one again.
14a.8 The trial involves no payment, so §8 (withdrawal) has nothing to operate on. You may stop, or delete the Account, at any moment (§18.2).
15.1 Every Book includes a print-ready file. We supply the file; we are not a printer and we do not print, bind or ship anything. Choosing a printer, placing the order and paying for it are your responsibility.
15.2 The file is produced to the specification stated in the Studio at the time you build it — page size, binding allowance, bleed and colour conversion. We are responsible for the file conforming to that specification.
15.3 We are not responsible for what a third-party printer does with it. Printed colour differs from a screen; paper, press, ink and finishing all change the result; trimming has physical tolerances. Differences of this kind are inherent to printing and are not a lack of conformity of the file. If your printer requires a different specification, tell us and we will help where we reasonably can.
15.4 We recommend ordering a single proof copy before any larger print run. We cannot reimburse the cost of a print run you ordered without one.
16.1 Narration is optional and separately priced. It is produced with synthetic voices licensed from a third-party provider.
16.2 The narration audio for your Book is supplied for your personal and family use on the same basis as §10.5. You may not extract, re-use or redistribute the voice itself, use the audio to train or clone a voice model, or present the voice as that of a real identified person.
16.3 Synthetic narration mispronounces things, particularly names and invented words. We will re-generate a chapter within your attempts (§6) to try to improve it; a pronunciation you dislike is a matter of §7.4.
16.4 We do not clone the voice of a real person, and we will not do so on request.
17.1 We take reasonable care to keep the Service available but do not guarantee uninterrupted operation. Maintenance, updates, and failures of networks, devices or third-party providers can interrupt it. Where we can foresee a significant interruption we will try to give notice.
17.2 We develop the Service continuously and may add, change or remove features. We will not make a change that materially reduces what you have already bought for a Book you have already paid for.
17.3 Dependency on AI providers, honestly stated. We rely on third-party models. A provider may change, degrade, re-price or withdraw a model at any time. Where that happens we may substitute a model we reasonably consider equivalent or better, which may produce visibly different results. Where a capability you have paid for becomes permanently unavailable and no equivalent exists, we will bring the contract into conformity or, if that is impossible, refund the part of the price attributable to the unavailable capability. A provider's failure is our supply risk, not force majeure, and §19 governs anything beyond this clause.
17.4 We may set fair technical limits — file sizes, upload counts, request rates, storage — and change them, so that the Service works for everyone.
17.5 Changing something you already bought — the rules we hold ourselves to. A Book, once delivered, is not modified afterwards: it is a one-off supply and it stays as you approved it. For anything supplied continuously (the Membership, the Reader, the Studio) we may make changes only for a justified reason — keeping the Service secure, adapting it to a change in law, a technical necessity, or adding to what it does — and never at extra cost to you.
17.6 If such a change would negatively and materially affect your access or use, we will tell you in advance on a durable medium, explaining what changes, when, and what you may do about it. You may then terminate, with no notice period, within 30 days of the change or of being told about it, whichever is later — and we refund the unused part. That right does not arise if we keep the unchanged version available to you, working and at no extra cost.
18.1 The Account relationship is concluded for an indefinite period and is free of charge in itself.
18.2 You may stop at any time, by cancelling the Membership (§14.6) and, if you wish, deleting your Account in the Account settings. Deleting the Account deletes your data as described in our privacy policy — download everything you want to keep first, because deletion is irreversible. The end of a Trial does not delete the Account; it only rests the shelf as described in §14a.3.
18.3 We may suspend or terminate your Account, or refuse a transaction, if: you materially breach these Terms and do not remedy the breach within 14 days of our request (or immediately, where §12.3 applies or where waiting would be unreasonable); you fail to pay; you use the Service unlawfully or in a way that endangers it or other users; or we are required to by law.
18.4 Except where §12.3 applies, we will give you reasonable notice and, where the law provides for it, refund the unused part of anything you have prepaid.
18.5 The guarantee that survives everything. A Book you have bought, its print-ready file, and every copy already downloaded to your devices remain yours and usable:
We will not build any technical measure that revokes access to a copy already delivered to your device, and we will not use one. This guarantee does not apply to material that is unlawful (§12.3), or for which you have received a refund (§8.6).
18.6 If we ever discontinue the Service, we will give Consumers at least 90 days' notice, keep the download and print-file functions working for that period, and refund the unused part of any Membership.
18.7 §§7–12, §18.5, §19, §21 and §22 survive termination.
19.1 We are liable for failing to perform this contract with due care, on the terms below and subject always to §19.6.
19.2 To the fullest extent permitted by law, we are not liable for: loss of profit, revenue, goodwill or anticipated savings; loss of or damage to data beyond our duty to keep the Service in conformity; a third-party printer's output (§15.3); a third-party AI provider's output beyond §17.3; anything caused by your breach of §11 or §12; or consequences of your own device, network or third-party software.
19.3 Cap. To the fullest extent permitted by law, our total liability arising from or in connection with a Book is limited to the amount you paid for that Book and its add-ons in the 12 months before the event; and in connection with the Membership, to the Membership fees you paid in the 12 months before the event.
19.4 We are not liable for delay or failure caused by an event beyond our reasonable control — natural disaster, war, civil unrest, epidemic, a general failure of internet infrastructure, a legal prohibition, or an act of a public authority. This does not cover a supplier's ordinary failure (§17.3).
19.5 You must tell us about a problem within a reasonable time of noticing it, so that we can limit the damage. This does not shorten any statutory time limit.
19.6 Nothing in §19 or anywhere in these Terms excludes or limits: liability for damage caused intentionally (art. 473 §2 of the Civil Code); liability for death or personal injury caused by our fault; a Consumer's statutory rights on non-conformity (§7.2) and withdrawal (§8); or any other liability that cannot lawfully be excluded or limited. Where any limitation in §19 is void as against a Consumer, it does not apply to that Consumer, and the rest of §19 continues to apply.
20.1 We process personal data as controller, as described in our privacy policy, which forms part of the information we give you but is not a contractual term. In case of conflict about how we handle data, the privacy policy governs.
20.2 In summary: we process what we need to make your book and run your Account; reference photographs of children are used only to paint your child in your own book and are never published, shared or used for training; you may delete them, a child's profile, or the whole Account at any time; and you can complain to the President of the Personal Data Protection Office (PUODO).
20.3 This website stores nothing on your device for measurement unless you agree to it, and refusing leaves the site exactly as it was. What may be stored, who receives it, and how to change your answer are set out in full in the Privacy Notice.
21.1 We may amend these Terms for a valid reason — a change in law, a change in the Service, a new payment method, security, or correcting an error. We will notify Consumers at least 14 days before a change takes effect, by email and in the Service. If you do not accept a change you may terminate before it takes effect, without cost, and cancel the Membership with a refund of the unused part. A Book you have already bought remains governed by the version of these Terms in force when you bought it, except where a change is required by law or is purely in your favour.
21.2 These Terms exist in English and Polish, and both are authentic. For a Consumer habitually resident in Poland, the Polish version is binding and prevails. For anyone else, the version in the language in which you concluded the contract prevails; if that cannot be established, the English version prevails. The Polish version is at martym.com/pl/regulamin.
21.3 Polish law applies. If you are a Consumer, this does not deprive you of the protection of any mandatory rule of the law of your country of habitual residence (art. 6 of Regulation (EC) No 593/2008, Rome I).
21.4 If you are a Consumer, jurisdiction is determined by Regulation (EU) No 1215/2012: you may bring proceedings in the courts of your own domicile or ours, and we may bring proceedings only in the courts of your domicile. If you are not a Consumer, §22.5 applies.
21.5 If a provision of these Terms is or becomes invalid, the rest remains in force, and the invalid provision is replaced by the applicable statutory rule — or, where none applies and you are not a Consumer, by a valid provision closest to the intended economic purpose.
21.6 You may not transfer your rights under these Terms without our consent. We may transfer ours to a successor in the business, provided your rights are unaffected; we will tell you if we do, and you may terminate if you object.
21.7 Our not enforcing a right immediately does not waive it.
21.8 We communicate with you by email and in the Service; you communicate with us at the addresses above. Keep your email address current.
21.9 These Terms, the pricing page and the purchase confirmation are the whole of the agreement between us, and the privacy policy is the notice we give you about personal data (§20.1); together they replace any earlier understanding. Marketing copy on our website describes the Service but does not add terms beyond these; where marketing appears to promise more than these Terms, tell us — we would rather fix the promise than argue about it.
22.1 This §22 applies only where you are not a Consumer (§1.1) — for example a company, an institution or a school. It replaces the clauses it names.
22.2 §§7.2, 8 and 9.2–9.3 do not apply. There is no right of withdrawal, no statutory consumer conformity regime and no consumer complaint deadline. Our statutory warranty for defects is excluded to the fullest extent permitted (art. 558 §1 of the Civil Code). The Service is supplied as is.
22.3 Our total liability to you is limited to the fees you paid us in the three months before the event, and we are not liable for lost profits or any indirect or consequential loss. §19.6's first two limbs (intentional damage; death or personal injury) continue to apply.
22.4 You will indemnify us and hold us harmless against all claims, proceedings, damages, penalties and reasonable legal costs arising from your Input, your breach of §11 or §12, or your commercial use of a Deliverable.
22.5 Disputes are subject to the exclusive jurisdiction of the Polish court having jurisdiction over our registered office.
22.6 Commercial use of Deliverables requires a separate written agreement under §10.5. Nothing in §22 grants it.
23.1 You can keep a copy of this agreement. These Terms are available free of charge, before you buy anything, on a page you can print, save or download, so that you can store and reproduce them. If you would like them as a file, ask and we will send one.
23.2 No geo-blocking. We do not refuse or restrict access to the Service, or apply different conditions of access, because of your nationality, your place of residence or where you happen to be in the EU. Prices differ only by the VAT your own country requires (§5.3).
23.3 Accessibility. We aim to make the Service perceivable, operable, understandable and robust, including keyboard operation, sufficient contrast, text scaling and reduced motion. We monitor and improve accessibility in line with the laws that apply to the Service. If a barrier prevents you from using it, write to hello@martym.com; we will provide reasonable help and treat the barrier as a defect worth fixing.
23.4 We follow no external code of conduct that would add obligations beyond these Terms.
You may, but need not, use this form. Sending any clear statement is enough.
