Privacy Policy

Last updated: 19 July 2026

This Privacy Notice for Marinos Ventures (doing business as kimaboo) ("we," "us," or "our"), describes how and why we might access, collect, store, use, and/or share ("process") your personal information when you use our services ("Services"), including when you:

  • Visit our website at https://kimaboo.com or any website of ours that links to this Privacy Notice
  • Use kimaboo. Kimaboo lets you create personalised, illustrated children’s books. You provide details about the child (name, appearance as selections and descriptions, a story theme) and we use generative AI to produce a story and matching illustrations, delivered as a digital preview and, after purchase, as downloadable PDF files.
  • Engage with us in other related ways

Questions or concerns? Reading this Privacy Notice will help you understand your privacy rights and choices. We are responsible for making decisions about how your personal information is processed. If you do not agree with our policies and practices, please do not use our Services. If you still have any questions or concerns, please contact us at legal@marinos-ventures.com.

SUMMARY OF KEY POINTS

What personal information do we process? When you visit, use, or navigate our Services, we may process personal information depending on how you interact with us and the Services, the choices you make, and the products and features you use. Learn more about personal information you disclose to us.

Do we process any sensitive personal information? No — we do not collect or process sensitive personal information. "Sensitive" means information such as ethnic origin, sexual orientation or religious beliefs — none of which is relevant for kimaboo or collected.

Do we collect any information from third parties? Only if you sign in with a social login: then we receive basic profile data (name, email address, profile picture) from that provider. Otherwise, we do not collect information from third parties.

Who do we share personal information with? Only with the service providers we need to run kimaboo — our payment provider (Stripe), the AI providers that generate stories and illustrations (OpenAI, Google), our email delivery and hosting providers — and otherwise only where the law requires it. We never sell personal information. Learn more in "When and with whom do we share your personal information?"

What are your rights? Depending on where you are located geographically, the applicable privacy law may mean you have certain rights regarding your personal information. Learn more about your privacy rights.

How do you exercise your rights? The easiest way to exercise your rights is by visiting https://kimaboo.com/contact, or by contacting us. We will consider and act upon any request in accordance with applicable data protection laws.

TABLE OF CONTENTS

1. WHAT INFORMATION DO WE COLLECT?

Personal information you disclose to us

In Short: We collect personal information that you provide to us.

We collect personal information that you voluntarily provide to us when you register on the Services, express an interest in obtaining information about us or our products and Services, when you participate in activities on the Services, or otherwise when you contact us.

Personal Information Provided by You. The personal information that we collect depends on the context of your interactions with us and the Services, the choices you make, and the products and features you use. The personal information we collect may include the following:

  • email addresses
  • names
  • passwords
  • profile picture
  • preferred language
  • support messages
  • book input information
  • generated content

Sensitive Information. We do not process sensitive information.

Payment Data. Payments are processed by Stripe. Your payment card details are entered directly into Stripe’s payment form and are handled and stored by Stripe — they never reach our servers. We receive and store the payment amount, currency, payment method type, your email address, a payment reference, and — for fraud prevention and as evidence in payment disputes — the IP address used at checkout. You may find Stripe’s privacy notice here: https://stripe.com/privacy.

All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.

Information automatically collected

In Short: Some information — such as your Internet Protocol (IP) address and/or browser and device characteristics — is collected automatically when you visit our Services.

When you visit the Services, our servers and reverse proxy automatically record technical access data: IP address, browser type and version, operating system, referring URL, pages visited, and timestamps. In our analytics, IP addresses are anonymized; the raw server logs are used for security and troubleshooting and are retained only for a limited period (see section 8). We derive at most a coarse, country-level location from the IP address — we do not collect precise location data.

Like many businesses, we also collect information through cookies and similar technologies. You can find out more about this in our Cookie Notice: kimaboo.com/cookies.

2. HOW DO WE PROCESS YOUR INFORMATION?

In Short: We process your information to provide, improve, and administer our Services, communicate with you, for security and fraud prevention, and to comply with law. We process the personal information for the following purposes listed below. We may also process your information for other purposes only with your prior explicit consent.

We process your personal information for a variety of reasons, depending on how you interact with our Services, including:

  • To facilitate account creation and authentication and otherwise manage user accounts. We may process your information so you can create and log in to your account, as well as keep your account in working order.
  • To deliver and facilitate delivery of services to the user. We may process your information to provide you with the requested service.
  • To respond to user inquiries/offer support to users. We may process your information to respond to your inquiries and solve any potential issues you might have with the requested service.
  • To send administrative information to you. We may process your information to send you details about our products and services, changes to our terms and policies, and other similar information.
  • To fulfill and manage your orders. We may process your information to fulfill and manage your orders, payments, returns, and exchanges made through the Services.
  • To protect our Services. We may process your information as part of our efforts to keep our Services safe and secure, including fraud monitoring and prevention.
  • To identify usage trends. We may process information about how you use our Services to better understand how they are being used so we can improve them.

3. WHAT LEGAL BASES DO WE RELY ON TO PROCESS YOUR PERSONAL INFORMATION?

In Short: We only process your personal information when we believe it is necessary and we have a valid legal reason (i.e., legal basis) to do so under applicable law, like with your consent, to comply with laws, to provide you with services to enter into or fulfill our contractual obligations, to protect your rights, or to fulfill our legitimate business interests.

In concrete terms, we rely on the following legal bases of the GDPR:

  • Performance of a contract (Art. 6(1)(b) GDPR): your account, generating and delivering your books, processing payments and orders, and providing support.
  • Legitimate interests (Art. 6(1)(f) GDPR): security and fraud prevention, anonymized server logs, and cookieless, anonymous usage statistics (with the opt-out described in section 5).
  • Consent (Art. 6(1)(a) GDPR): optional session recording (section 5). You can withdraw consent at any time.
  • Legal obligation (Art. 6(1)(c) GDPR): retention of payment and invoicing records under tax and commercial law.

Providing your email address and payment data is required to conclude and perform the contract — without it, we cannot provide an account or paid books. All other information is voluntary.

4. WHEN AND WITH WHOM DO WE SHARE YOUR PERSONAL INFORMATION?

In Short: We share personal information only with the service providers listed below (as processors under Art. 28 GDPR), in the specific situations described here, or where required by law. We do not sell personal information.

We use the following service providers, who process personal data on our behalf and may use it only to provide their service to us:

  • Stripe (Stripe, Inc., USA / Stripe Payments Europe, Ireland) — payment processing and fraud prevention.
  • OpenAI (OpenAI, L.L.C., USA) — generation of the story text and content moderation. Receives the book inputs (child’s name, appearance selections, story theme).
  • Google (Google LLC, USA — Gemini API) — generation of the illustrations. Receives illustration prompts derived from the book inputs and internally generated reference images.
  • Resend (Resend, Inc., USA) — delivery of transactional emails (verification, password reset, order and book notifications).
  • Hetzner (Hetzner Online GmbH, Germany) — hosting of our servers and object storage for generated books and images. All book content is stored in the EU.
  • Cloudflare Turnstile (Cloudflare, Inc., USA) — bot protection on the registration and password-reset forms, where enabled.

Transfers to third countries. Where providers process data in the USA, the transfer is safeguarded by an adequacy decision under the EU–US Data Privacy Framework and/or the EU Standard Contractual Clauses (Art. 44 et seq. GDPR). Generated books and images themselves are currently stored on our own infrastructure in the EU.

We may also disclose personal information in the following situations:

  • Business Transfers. We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
  • Legal obligations. Where we are legally required to do so, for example to authorities on the basis of a binding request.

5. DO WE USE COOKIES AND OTHER TRACKING TECHNOLOGIES?

In Short: We may use cookies and other tracking technologies to collect and store your information.

We use cookies and similar technologies only where they are necessary for the site to function (authentication, form data, payment processing, your cookie choices) and — separately and optionally — for analytics. We use no advertising or tracking cookies of third-party ad networks.

For website analytics we use Umami, a privacy-friendly tool that we host ourselves. The anonymous reach measurement works without cookies and without storing any personal data; it stores nothing on your device and honors your browser’s "Do Not Track" setting. We rely on it under our legitimate interest in understanding and improving our Services, and you can opt out at any time in our cookie settings. Optional session recording (a sampled, masked replay of interactions) runs only if you give your consent. Separately, our servers and reverse proxy keep access logs — in which IP addresses are anonymized — that we use for security and aggregate traffic statistics under our legitimate interest, and which we retain only for a limited period.

Specific information about how we use such technologies and how you can refuse certain cookies is set out in our Cookie Notice: kimaboo.com/cookies.

6. HOW DO WE USE ARTIFICIAL INTELLIGENCE?

In Short: Your books are generated with AI models operated by third-party providers, who act as our processors and do not use your data for training.

To generate your book we send the book inputs (the child’s name, appearance selections and descriptions, the story theme) and internally generated reference images as prompts to our AI providers: OpenAI (story text, content checks) and Google (Gemini API — illustrations). These providers act as processors for us and may use the data only to provide their service. We use API offerings under terms in which the providers commit not to use the submitted content to train their own models. We may change or add AI service providers in the future; this notice will be updated accordingly.

The generated stories, illustrations and PDF files are currently stored on our own infrastructure in the EU. Should we use storage locations outside the EU in the future, we will ensure compliance with Art. 44 et seq. GDPR and update this notice. We do not upload photographs of children, and appearance is described only through the selections and text you provide.

7. HOW DO WE HANDLE SOCIAL LOGINS?

Where we offer registration or login with a third-party account (for example Google, Apple or Facebook), we receive from the provider only the profile information needed to create your account — typically your name, email address and profile picture. We do not access your contacts or friend lists. The provider’s own processing is governed by its privacy notice; we recommend reviewing it. You can disconnect a social login by deleting your account or contacting us.

8. HOW LONG DO WE KEEP YOUR INFORMATION?

In Short: We keep personal information only as long as needed for the purposes described here or as required by law. The concrete periods are:

  • Account and book data (including the child’s name and the generated books): for as long as you have an account. When you delete your account, your personal account data is removed immediately and your books are retained for a 30-day grace period (so an accidental deletion can be undone by contacting us), then permanently deleted.
  • Unverified accounts: registrations that are never email-verified and show no activity are deleted after 7 days.
  • Payment and invoicing records (including the checkout IP address stored with the payment): retained for the statutory retention periods of tax and commercial law (up to 10 years in Germany, Section 147 AO).
  • Support messages: up to 3 years.
  • Server logs and usage statistics (IP-anonymized): 90 days.
  • Records of your contractual declarations (acceptance of the Terms, consents to immediate performance): kept as long as needed to evidence the contract, at most as long as the associated payment records.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.

9. HOW DO WE KEEP YOUR INFORMATION SAFE?

In Short: We aim to protect your personal information through a system of organizational and technical security measures.

We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk. You should only access the Services within a secure environment.

10. DO WE COLLECT INFORMATION FROM MINORS?

Our Services are intended exclusively for adults; accounts may only be created by persons aged 18 or over — we do not create accounts for children. To create personalised books, however, we do process personal data about children (for example the name and selected characteristics), provided by parents or other adults entitled to provide it (details in section 14). If we learn that a minor has created an account themselves, we will deactivate the account and delete its data. If you become aware of such a case, please contact us at legal@marinos-ventures.com.

11. WHAT ARE YOUR PRIVACY RIGHTS?

In some regions (like the European Economic Area (EEA), UK, Switzerland, and Canada), you have certain rights under applicable data protection laws. These may include the right (i) to request access and obtain a copy of your personal information, (ii) to request rectification or erasure; (iii) to restrict the processing of your personal information; (iv) if applicable, to data portability; and (v) not to be subject to automated decision-making. If a decision that produces legal or similarly significant effects is made solely by automated means, we will inform you, explain the main factors, and offer a simple way to request human review. In certain circumstances, you may also have the right to object to the processing of your personal information. You can make such a request by contacting us by using the contact details provided in the section "How can you contact us about this notice?" below.

You also have the right to lodge a complaint with a data protection supervisory authority. The authority responsible for us is the Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen (LDI NRW), www.ldi.nrw.de. You can also contact the authority of your EU member state.

Withdrawing your consent: If we are relying on your consent to process your personal information, which may be express and/or implied consent depending on the applicable law, you have the right to withdraw your consent at any time. You can withdraw your consent at any time by contacting us by using the contact details provided in the section "How can you contact us about this notice?" below or updating your preferences.

However, please note that this will not affect the lawfulness of the processing before its withdrawal nor, when applicable law allows, will it affect the processing of your personal information conducted in reliance on lawful processing grounds other than consent.

Account Information

If you would at any time like to review or change the information in your account or terminate your account, you can:

  • Log in to your account settings and update your user account.

Upon your request to terminate your account, we will remove your personal account data immediately. Your books are retained for a 30-day grace period and then permanently deleted (section 8). We retain what the law requires us to keep — in particular payment records under tax law — and information needed to prevent fraud or enforce our legal terms.

Cookies and similar technologies: Most Web browsers are set to accept cookies by default. If you prefer, you can usually choose to set your browser to remove cookies and to reject cookies. If you choose to remove cookies or reject cookies, this could affect certain features or services of our Services. For further information, please see our Cookie Notice: kimaboo.com/cookies.

If you have questions or comments about your privacy rights, you may email us at legal@marinos-ventures.com.

12. CONTROLS FOR DO-NOT-TRACK FEATURES

Most web browsers include a Do-Not-Track ("DNT") setting that signals your preference not to be tracked. Our self-hosted analytics honors the DNT signal: page views from browsers with DNT enabled are not measured. We also honor the Global Privacy Control (GPC) signal as an opt-out where applicable law gives it effect. Beyond that, no uniform standard for responding to DNT signals has been finalized; if one is adopted, we will inform you about that practice in a revised version of this notice.

13. USERS OUTSIDE THE EEA

We voluntarily extend the rights and protections described in this notice (access, rectification, erasure, portability, objection) to all users worldwide — including outside the European Economic Area (EEA) — regardless of where you live. Depending on your country or state of residence, additional local rights may apply to you; to exercise any right, simply contact us via kimaboo.com/contact or legal@marinos-ventures.com. We do not sell personal information.

14. CHILDREN’S DATA

Kimaboo is used by adults to create books for children. The child’s name and the appearance details you select are treated as personal data of the child and are used solely to generate the book (section 6). Please enter only the details needed for the book, and only if you are entitled to provide them — as a rule, as the child’s parent or with the consent of the persons having parental responsibility. We do not request or process photographs of children.

15. DO WE MAKE UPDATES TO THIS NOTICE?

We may update this Privacy Notice from time to time. The current version is indicated by the "Last updated" date at the top of this notice. If we make material changes, we will inform you by a prominent notice on the website or directly, for example by email. We encourage you to review this notice regularly.
