Who we are

Fablum is developed and published by Mad Bunnies (eenmanszaak), Kometenstraat, 1223 CM Hilversum, The Netherlands. KvK: 42018802. Email: support@madbunnies.dev.

Acceptance

By downloading, installing, or using Fablum, you agree to these terms. If you do not agree, do not use the app.

You must be at least 16 years old to use Fablum, or have permission from a parent or legal guardian. Additional age and parental-consent rules apply to in-app purchases under Apple’s and Google’s account terms; you must comply with those as well.

The app

Fablum is an e-book reader and library manager for personal, non-commercial use. All processing happens on your device. We do not host or provide book content — the app connects to third-party catalogs to let you browse and download books (see “Third-party content” below).

Fablum is free to download and use, with a built-in limit on the size of your library. You may unlock an unlimited library through a one-time in-app purchase, as described in “Pricing and in-app purchases”.

Pricing and in-app purchases

Free tier

Fablum is free to download. Without any purchase you may add up to 5 books to your library across all supported sources (device files, direct URLs, or built-in catalogs). All core reading features — including offline reading, reading themes, search and sorting, metadata editing, text-to-speech for EPUB, and browsing built-in catalogs — are available in the free tier without any limit.

We reserve the right to adjust the size of the free tier in future versions of the app, including for users who have not purchased the unlock, with reasonable advance notice through the app or these terms. Books you have already added to your library will remain accessible even if the free-tier limit is later reduced. Where a change to the free tier materially and negatively affects your continued use of the app, you have the right to terminate the contract free of charge, without prejudice to your other statutory rights, including those under Directive (EU) 2019/770 on digital content and digital services and the law of your country of residence implementing it.

Fablum Unlimited (one-time in-app purchase)

You may remove the 5-book limit at any time by purchasing Fablum Unlimited, an optional one-time, non-consumable in-app purchase. The base price set for the Netherlands is €9.99, inclusive of Dutch VAT at the rate applicable at the time of purchase. In every other market, the price is set automatically by Apple or Google to the local-currency equivalent of that base price using their own price-tier tables, and may differ from a direct currency conversion because of platform pricing tiers, local taxes, and currency rounding. The exact price you will pay in your country, inclusive of all applicable taxes, is always shown to you by the App Store or Google Play before you confirm the purchase.

Fablum Unlimited:

• is a one-time purchase, not a subscription, and will not auto-renew;
• gives you a lifetime entitlement to add an unlimited number of books to your Fablum library on devices linked to the Apple ID or Google account that made the purchase, for as long as the app remains available on the relevant store and we continue to operate it (see “Discontinuation”);
• does not unlock any content. Fablum does not sell books; the unlock affects only the size limit of your personal library.

“Lifetime” here means the period during which Mad Bunnies continues to operate Fablum and the relevant app store continues to support the entitlement, as described in “Discontinuation”. It does not refer to the natural lifetime of the user, and it does not commit Mad Bunnies, Apple, or Google to operate the service indefinitely.

The product identifier is fablum_lifetime_unlock_03052026.

Sellers of record

The seller of record for Fablum Unlimited is:

• On iOS / iPadOS / macOS: Apple Distribution International Limited (Hollyhill Industrial Estate, Hollyhill, Cork T23 YK84, Ireland).
• On Android: Google Commerce Limited (Gordon House, Barrow Street, Dublin 4, Ireland) for users in the EU/EEA and the United Kingdom; Google LLC or another local Google entity in other regions.

Apple’s and Google’s own terms — including the Apple Media Services Terms and the Google Play Terms of Service — govern the contractual relationship between you and them for the payment, billing, taxation, and refund handling of the purchase. These terms only govern the relationship between you and Mad Bunnies as the developer of the app and the provider of the digital content delivered by the unlock.

Restoring purchases

Because Fablum has no user accounts, your unlock is tied to the Apple ID or Google account that made the purchase. After reinstalling the app on the same or a new device signed in to that account, you can re-apply the unlock at any time using the Restore Purchases function in Fablum’s settings.

Family Sharing and Family Library

Fablum Unlimited is configured as a non-consumable purchase. Where Apple Family Sharing or Google Play Family Library is enabled by you, the entitlement may extend to other members of your family group in line with Apple’s and Google’s family-sharing rules, which may change over time. Mad Bunnies does not control the conditions under which an unlock is shared between family members.

Pre-purchase library

Books you added to Fablum before buying the unlock remain in your library and remain readable, even if you never make a purchase. The 5-book limit applies only to adding new books in the free tier.

Price changes

Prices may change in the future. Any price change applies only to new purchases of Fablum Unlimited and will not affect users who have already bought the unlock at an earlier price. We may also adjust the Netherlands base price or any individual non-NL price tier independently — for example to follow App Store or Google Play tier changes in a specific country.

Refunds and your statutory rights

Refund requests for Fablum Unlimited are handled by the seller of record:

• On iOS / iPadOS / macOS: Apple, via reportaproblem.apple.com or your purchase history in the App Store.
• On Android: Google, via your Google Play purchase history or Google Play support.

We are not able to grant refunds directly because we do not process the payment. We will, however, in good faith assist Apple or Google with information they need to evaluate a refund request where applicable.

EU and EEA: right of withdrawal for digital content

If you are a consumer resident in the European Union or the European Economic Area, you normally have a 14-day right of withdrawal from a distance contract for digital content under EU Directive 2011/83/EU on consumer rights, as amended by Directive 2019/2161, and the corresponding provisions of Dutch law (Boek 6, Titel 5, Afdeling 2B BW).

For digital content delivered immediately, that right is lost in accordance with Article 16(m) of Directive 2011/83/EU once you have:

• given your express prior consent to the immediate performance of the contract, and
• acknowledged that you lose your right of withdrawal once performance has begun, and
• received confirmation of the contract on a durable medium.

The Apple App Store and Google Play purchase flows for non-consumable in-app purchases like Fablum Unlimited are designed to collect this consent and acknowledgement and to provide the confirmation as part of the standard checkout flow. Where those conditions have been met and the unlock has been delivered, the right of withdrawal may have lapsed by the time the unlock is active. If you believe these conditions were not met in your purchase flow, contact us at support@madbunnies.dev and we will work in good faith with Apple or Google to investigate your refund request. This does not affect any mandatory consumer rights you have under the law of your country of residence, including remedies for non-conformity of digital content under Directive 2019/770 and the implementing law in your country.

United Kingdom

If you are a consumer in the UK, equivalent provisions apply under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 and the Consumer Rights Act 2015 for digital content.

Other regions

Refund and consumer-rights frameworks elsewhere — including the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010), the Brazilian Código de Defesa do Consumidor, the U.S. state-level consumer protection statutes, and similar laws — apply on top of these terms to the extent they grant you non-excludable rights. Nothing in these terms limits any such non-excludable rights.

Your content

Books and files you import into Fablum remain yours. We do not access, store, copy, or transmit your files. You are solely responsible for ensuring you have the legal right to use, store, and read the content you import. We are not responsible for any content you add to the app.

Acceptable use

You agree not to:

• circumvent or attempt to circumvent the 5-book free-tier limit, the in-app purchase verification, the restore-purchases mechanism, or any other technical measure built into the app;
• use the app to download, store, or distribute content you do not have the legal right to use;
• use the app in any way that violates applicable law in your country, including copyright, export control, or sanctions law;
• use the app on behalf of, or for the benefit of, anyone whom you know or should reasonably know is subject to international sanctions that prohibit the supply of digital products to them.

Intellectual property

Fablum, including its design, code, and trademarks, is owned by Mad Bunnies. These terms grant you a personal, non-exclusive, non-transferable license to use the app on devices you own or control, in accordance with the applicable app store terms, and a personal, non-exclusive, non-transferable license to use any in-app purchase you have made on those devices. You may not copy, modify, distribute, or create derivative works from the app. You may not reverse-engineer or decompile the app, except to the extent that such restriction is prohibited by applicable law, including the right to decompile for interoperability purposes under EU Directive 2009/24/EC.

Disclaimer of warranties

Fablum is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. Nothing in this disclaimer affects any statutory rights that cannot be waived or limited under applicable law, including your rights under EU Directive 2019/770 on digital content and digital services, your conformity rights as a paying consumer for the unlock, and non-excludable consumer guarantees under the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010).

We do not guarantee that the app will be uninterrupted, error-free, secure, or free of bugs. We do not guarantee compatibility with any particular device, operating system version, or file format. We do not guarantee that any specific built-in catalog (including Project Gutenberg) will remain available, that any specific roadmap feature will ship, or that the app will continue to be distributed on every store on which it is currently available.

Limitation of liability

To the maximum extent permitted by applicable law, Mad Bunnies shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, goodwill, or other intangible losses, arising from or related to your use of or inability to use Fablum or any in-app purchase.

These limitations do not exclude or limit liability where it cannot be excluded or limited under applicable law, including liability for:

• intentional misconduct or gross negligence (opzet of grove schuld);
• death or personal injury caused by negligence;
• fraud or fraudulent misrepresentation;
• conformity defects in paid digital content under EU Directive 2019/770 and the implementing law in your country;
• any other liability that cannot be excluded under mandatory provisions of Dutch law or EU consumer protection law.

Third-party content

Fablum provides access to book catalogs operated by third parties, including Project Gutenberg (gutenberg.org). Books available through these catalogs are provided by their respective operators, not by Mad Bunnies. We do not own, host, curate, or verify this content.

Books in the Project Gutenberg catalog are in the public domain in the United States. They may still be protected by copyright in other countries. You are responsible for determining the copyright status of any work in your jurisdiction before downloading or using it.

We make no guarantees about the availability, accuracy, completeness, or legality of third-party catalog content. We are not liable for any claims arising from your use of content obtained through these catalogs.

“Project Gutenberg” is a trademark of the Project Gutenberg Literary Archive Foundation, used here for identification purposes only.

Data loss

We are not liable for any loss of data, including books, reading progress, bookmarks, highlights, library organization, or the locally stored unlock receipt, resulting from device failure, operating system updates, app updates, or any other cause. All data is stored locally on your device. We recommend keeping backups of your book files. The unlock itself can be re-applied at any time using “Restore Purchases” as long as you sign in with the Apple ID or Google account that made the purchase.

Third-party platforms

Fablum is distributed through the Apple App Store and Google Play, and any in-app purchase is processed through Apple StoreKit or Google Play Billing. Your use of the app and of any in-app purchase is also subject to the terms of service of the platform through which you obtained it, including the Apple Media Services Terms and the Google Play Terms of Service. In the event of a conflict between these terms and the applicable app store terms, the app store terms prevail to the extent required by that platform.

With respect to Apple:

• Apple Inc. and its subsidiaries are third-party beneficiaries of these terms. Upon your acceptance, Apple has the right to enforce these terms against you.
• Apple has no obligation to provide maintenance, support, or warranty for Fablum.
• Apple is not responsible for addressing any claims by you or any third party relating to the app, including product liability claims, claims that the app fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection or similar legislation.
• Apple is not responsible for the investigation, defense, settlement, or discharge of any third-party claim that the app or your use of it infringes a third party’s intellectual property rights.

Google is not a party to these terms and has no obligation to provide maintenance, support, or warranty for Fablum.

Changes to these terms

We may update these terms from time to time. When we do, we will revise the “Last updated” date at the top of this page. For material changes that affect your rights or obligations — including changes to the size of the free tier, the price or scope of any in-app purchase available to new buyers, or the consumer-rights provisions — we will notify you through the app or other appropriate means before the changes take effect. If you do not agree with the updated terms, you should stop using the app.

Changes to these terms do not retroactively reduce the entitlement of a user who has already purchased Fablum Unlimited.

Termination

You may stop using Fablum at any time by uninstalling the app. We may discontinue the app or terminate your license with reasonable notice, or immediately if you materially breach these terms. Upon termination, all rights granted to you under these terms cease, except for any rights that you cannot waive under applicable consumer-protection law and except for any rights you have under Apple’s or Google’s terms with respect to a previously purchased non-consumable in-app product. Sections that by their nature should survive termination (including intellectual property, disclaimer of warranties, limitation of liability, refunds and statutory rights, and governing law) will continue to apply.

Discontinuation

We may, at our discretion, stop distributing Fablum or remove specific features (including the in-app purchase). If we discontinue Fablum Unlimited as a sellable product on a store, we will, where reasonably practicable, continue to honor existing entitlements on devices that already hold a valid receipt. We are not, however, able to override any decision by Apple or Google to remove the app from their store or to prevent its continued operation on a particular device or operating-system version.

Governing law and jurisdiction

These terms are governed by the laws of the Netherlands, without regard to conflict-of-law principles. Any dispute arising from or related to these terms shall be submitted to the competent court in Amsterdam, The Netherlands.

If you are a consumer resident in the EU/EEA, you also have the right to bring proceedings in the courts of your country of residence, and nothing in these terms limits any mandatory consumer protection rights available to you under the laws of your country. You may also contact the consumer authority or a recognised alternative dispute-resolution body in your country to seek out-of-court resolution of a dispute — in the Netherlands, this includes the Autoriteit Consument & Markt (ACM) and De Geschillencommissie. We are not, however, obliged to participate in alternative dispute resolution.

Privacy

Your privacy is important to us. Our collection and use of data, including data related to your in-app purchase, is described in our Privacy Policy. By using Fablum, you acknowledge that you have read the Privacy Policy.

Severability

If any provision of these terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
