Terms of Use (EULA)

Last updated: 06.08.2026

This End User License Agreement ("Agreement") is a legal agreement between you and Fabian Thanner ("we," "our," or "us") governing your use of BookletPro. It covers the BookletPro applications for iPhone, iPad and Mac (the "App") as well as the BookletPro web version at web.bookletpro.app (the "Web App"), together the "Services". By downloading or using the Services, you agree to be bound by this Agreement.

1. License

We grant you a personal, limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices that you own or control, as permitted by the Apple Media Services Terms and Conditions and the Usage Rules set out therein, and to use the Web App in a web browser for your own purposes.

2. The Service

BookletPro reorders and imposes pages of PDF documents you provide into print-ready booklets. All document processing happens locally: on your device in the App, and inside your browser in the Web App. Your documents are never uploaded to us.

3. Accounts (Web App)

Using the Web App requires a free account. Sign-in is passwordless: we email a one-time sign-in link to the address you provide. You must provide an email address you control, and you are responsible for keeping access to your mailbox and to any device on which you remain signed in. Accounts are personal; do not share your sign-in links. We may suspend or delete accounts that are used abusively or unlawfully. You can request deletion of your account at any time at [email protected].

4. PRO Subscription and Lifetime Purchase

BookletPro offers optional paid features ("PRO") in two forms:

In the App: payment is charged to your Apple Account at confirmation of purchase. Subscriptions automatically renew unless auto-renewal is turned off at least 24 hours before the end of the current period, and your Apple Account is charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel subscriptions in your Apple Account settings after purchase. Where required by law, you may be entitled to a refund through Apple; we do not process payments or refunds directly.

In the Web App: purchases are processed by Stripe acting as merchant of record, which means Stripe is your contractual seller for the transaction and handles payment, invoicing and taxes. Yearly subscriptions renew automatically until cancelled; you can cancel at any time in your account, and access continues until the end of the paid period. Cancelling stops future charges and does not refund the current period. Buying Lifetime while a yearly subscription is active cancels that subscription automatically. Refunds are handled through Stripe in accordance with applicable law.

PRO purchased in the App and PRO purchased in the Web App are separate purchases: an App Store purchase does not unlock the Web App, and vice versa.

5. Right of withdrawal (consumers)

We are not the seller of either purchase, so a statutory right of withdrawal is exercised against the seller and not against us:

If you buy as a consumer in the EU, the law gives you fourteen days to withdraw from a distance contract. For digital content that is supplied immediately and not on a physical medium, that right lapses once performance has begun with your express prior consent and your acknowledgement that you thereby lose it (§18(1)(11) FAGG, implementing Art. 16(m) of Directive 2011/83/EU). PRO is unlocked as soon as payment is confirmed, so the seller will normally ask you for that consent during checkout.

Nothing in this Agreement limits or replaces that right, and we make no promise on the seller’s behalf about how a request will be decided. If a refund is owed to you and the seller does not resolve it, write to [email protected] and we will help where we are able to.

6. Free Tier Limitations

Without a PRO purchase, booklets are limited to a maximum number of pages. PRO removes that limit and unlocks combining several PDFs, page ranges, binding margins and page numbers. Paper format, the back cover and printing are available to everyone. The exact limits may change over time; the limits in effect are the ones shown in the Services.

The Services contain no advertising. Neither the App nor the Web App shows ads, with or without PRO. Versions of the App before 3.0 were partly supported by third-party advertising (Google AdMob); that was removed in version 3.0. See our Privacy Policy.

7. Acceptable Use

You agree not to: (a) reverse engineer, decompile or disassemble the Services except to the extent permitted by law; (b) use the Services to process content you do not have the right to use; (c) use the Services for any unlawful purpose; or (d) interfere with the Web App’s operation, circumvent its limits or access controls, or place automated or excessive load on our servers. You are solely responsible for the documents you process and for ensuring you hold the necessary rights to them.

8. Intellectual Property

The Services and all related intellectual property rights are owned by us. This Agreement does not grant you any rights to our trademarks or branding. You retain all rights to the documents you import; we claim no ownership over your content.

9. Availability and Changes

The Web App is provided as an online service. We may change, suspend or discontinue it, in whole or in part, and we do not guarantee uninterrupted availability. If we permanently discontinue a paid feature you purchased, we will arrange a pro-rated refund for any unused prepaid period through the seller of that purchase, or compensate you ourselves where the seller cannot make the payment.

10. Disclaimer of Warranties

The Services are provided "as is" and "as available" without warranties of any kind, whether express or implied, including fitness for a particular purpose and non-infringement. We do not warrant that the Services will be uninterrupted, error-free, or that generated booklets will meet every printing requirement. Always review the preview before printing.

If you are a consumer, this section does not exclude or restrict the mandatory statutory rights you have — in particular the conformity rights the law gives you for digital content and digital services. Those rights apply regardless of what this section says.

11. Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of data or profits, arising out of your use of the Services.

This limitation does not apply to damage caused intentionally or by gross negligence, to injury to life, body or health, to liability under the Austrian Product Liability Act (Produkthaftungsgesetz), or to any other liability that cannot be excluded or limited by law. If you are a consumer, an exclusion or limitation in this Agreement applies only so far as Austrian consumer protection law allows it, in particular §6 of the Consumer Protection Act (KSchG); where it does not, the statutory rules apply in its place.

12. Apple’s Standard EULA

If you obtained the App from the Apple App Store, this Agreement supplements, and where it does not conflict is supplemented by, Apple’s Standard End User License Agreement. Apple has no obligation to furnish any maintenance or support services with respect to the App. Apple, and Apple’s subsidiaries, are third-party beneficiaries of this Agreement and may enforce it against you. This section applies to the App only and not to the Web App.

13. Termination

This Agreement is effective until terminated. Your rights under it terminate automatically if you fail to comply with any of its terms. Upon termination you must stop using the Services; we may close your Web App account.

14. Governing Law

This Agreement is governed by the laws of the Republic of Austria, excluding its conflict-of-law provisions and the UN Convention on Contracts for the International Sale of Goods, and subject to any mandatory consumer protection laws of your country of residence. If you are a consumer, you may also bring proceedings in the courts of your place of residence.
