Terms & Conditions

Last updated: August 31, 2026

The short version

Anything you create is yours — we claim no ownership of it.
Your content never leaves your device and is never used to train AI models.
You are responsible for having the rights to any content you use in the app.
The trial is free forever, but its exports are obfuscated — a license unlocks clean exports.
A license is a one-time purchase for life, tied to your account, with free updates until the next major version.
Back up your work — the app helps with recovery, but we are not liable for lost content.

This summary is for convenience only and is not part of the Terms. Please read the full Terms below.

These Terms & Conditions ("Terms") govern your access to and use of the Byte Binding desktop application (the "Service") and the bytebinding.com website (the "Site"), operated by Byte Binding ("we", "our", or "us"; see the Legal identification section below). By installing, accessing, or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

The Service

The Service is an offline desktop application for creating and editing digital publications. Your work is processed entirely on your device: we do not receive, store, or have access to the contents of your projects or exported files, as described in our Privacy Policy. The Site provides related functionality such as account management, purchases, downloads, and license management.

Eligibility

You must be at least 16 years old (or the minimum age required in your jurisdiction) to use the Service.

Your account

Some features of the Site and the Service require an account. You sign in through a third-party identity provider (such as Google or Amazon); we do not issue or store any passwords of our own. You are responsible for maintaining the security of the third-party account you use to sign in, for all activity that occurs under your Byte Binding account, and for notifying us promptly of any unauthorized use of it.

Trial Mode

The Service is available for evaluation free of charge in a trial mode ("Trial Mode"), which is enabled by default. You understand and agree that:

Trial Mode is not limited in time or functionality;
files exported in Trial Mode are intentionally obfuscated and are provided solely so that you can evaluate the Service. They are not suitable for commercial use, publication, or distribution of any kind;
Trial Mode ends only when you purchase a License (defined below) and activate it in the Service;
you may not remove, reverse, or circumvent the obfuscation applied to Trial Mode exports;
we may change the parameters of Trial Mode at any time.

License

Upon completion of a one-time purchase, we grant you a perpetual ("lifetime"), personal, non-exclusive, non-transferable license to install, activate, and use the Service on devices you own or control (the "License"). "Lifetime" means that your right to use the versions of the Service covered by your License does not expire; it is not a commitment to develop, update, or support the Service indefinitely.

Your License covers:

the major version of the Service that is current at the time of your purchase; and
all updates we release for that major version (including fixes, improvements, and new features), at no additional charge, until we release the next major version.

A "major version" is a new generation of the Service involving a substantial rework or redesign of the application, identified by an increase of the leading version number (for example, from version 1.x to version 2.0) and announced by us as a new major release. Routine improvements, fixes, and feature releases within the same version line are not major versions. New major versions may be offered as separate purchases or paid upgrades. If you choose not to purchase a new major version, your License and the versions it covers continue to work indefinitely, subject to these Terms.

A License is activated from within the Service through your account; there are no license keys to enter or manage. Activation requires an internet connection and a downloaded copy of the Service. Once activated, the Service does not require an internet connection for regular use.

The License is personal to you and tied to your account. You may not sell, rent, lend, sublicense, assign, or otherwise transfer the License, or share your account to extend the License to any other person or entity. We may apply reasonable technical limits on the number of concurrent activations of a single License.

License restrictions

Whether you use the Service in Trial Mode or under a License, you may not:

sell, rent, sublicense, redistribute, or otherwise make the Service available to any third party;
circumvent or attempt to circumvent the Service's licensing, activation, or Trial Mode mechanisms;
reverse engineer, decompile, or disassemble the Service, except to the extent permitted by applicable law;
remove or alter any proprietary notices;
use the Service for any unlawful purpose or in violation of these Terms.

We retain all rights, title, and interest in and to the Service, including all intellectual property rights. No rights are granted to you except as expressly set out in these Terms. We claim no ownership of the output you create with the Service, which is Your Content as described below.

Purchases and payment

Purchases are processed by a third-party payment provider acting as merchant of record. Your purchase is additionally subject to that provider's own terms and privacy policy, presented at checkout. Prices are stated at checkout and may include applicable taxes; we may change prices at any time, but price changes do not affect Licenses already purchased.

Because the Service can be fully evaluated in Trial Mode before purchase, purchases are generally final. If you are a consumer in the European Union, you may have a statutory right to withdraw from a distance purchase within 14 days. For digital content that is delivered immediately, the checkout may ask for your express consent to immediate delivery and your acknowledgment that you thereby lose this withdrawal right, as permitted by applicable law; where the withdrawal right applies and has not been lost in this way, it remains unaffected. Refunds are otherwise handled in accordance with the payment provider's refund policy and applicable law. Nothing in this section limits any statutory rights you have as a consumer.

Updates and support

We may release updates to the Service at our discretion. Updates are provided "as available": we do not commit to any particular update, feature, roadmap, or release schedule. We provide support on a reasonable-efforts basis via the contact address below and do not guarantee response times or issue resolution.

Pre-release versions

We may designate the Service, or certain builds or features, as alpha, beta, early access, or otherwise pre-release. Pre-release software is made available for evaluation, is incomplete and under active development, may contain errors or cause data loss, may change or be discontinued at any time without notice, and is provided without any warranty or support commitment. Access to pre-release software is personal to you and may be revoked at any time.

Your content

We claim no ownership of the books, files, and other content you create, edit, or otherwise process with the Service ("Your Content"). These Terms do not transfer any rights in Your Content to us — and they do not grant you any rights in Your Content, or in any third-party materials it incorporates, that you do not already hold. Your Content is processed entirely on your device and is not collected by us, as described in our Privacy Policy. We do not use Your Content to train artificial-intelligence or machine-learning models (including large language models), and we do not permit others to do so on our behalf.

The Service includes reasonable safeguards against content loss, such as project backups and recovery features. These safeguards are provided as a convenience: they are not guaranteed to prevent or reverse every loss, and they are not a substitute for your own backups. You remain solely responsible for Your Content and for maintaining independent backups of any important files. Although we take reasonable care to make the Service stable, no software is free of defects. To the maximum extent permitted by applicable law, we accept no responsibility or liability for any loss of, damage to, or corruption of Your Content, or for any damages arising from such loss, damage, or corruption, however caused.

Your Content may incorporate materials that you did not create yourself. You are solely responsible for ensuring that you hold all rights, licenses, and permissions required to use, reproduce, and distribute Your Content and any materials it incorporates, and that Your Content and your use of it comply with applicable laws and with the terms of any third-party licenses. We do not review Your Content, and we assume no responsibility or liability for Your Content, for the materials it incorporates, or for any claims arising from your failure to secure such rights or to comply with such requirements.

For the avoidance of doubt: we bear no responsibility or liability for any content that is unlawful or infringes the rights of others, whether such content is used with or produced by the Service. The availability of the Service does not constitute any review, endorsement, or approval of Your Content, and responsibility for the lawfulness of Your Content and of your use of the Service rests solely with you.

Feedback

We always welcome your feedback. If you submit ideas, suggestions, bug reports, or other feedback about the Service ("Feedback"), you grant us a perpetual, irrevocable, worldwide, royalty-free license to use, modify, and incorporate that Feedback into our products and services without any obligation or compensation to you.

You are welcome to talk about the Service publicly, including sharing screenshots, reviews, and your impressions. We only ask that, when talking about pre-release software, you make clear that it may change before release.

Third-party services and components

The Site and the Service rely on third-party services (such as payment processing and error monitoring) that are governed by their own terms and privacy policies. The Service may also include open-source software components; such components are governed by their respective licenses, which are not affected by these Terms.

Disclaimer of warranties

The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, secure, or free from data loss, or that files produced by the Service will meet the technical or legal requirements of any marketplace, distributor, or platform.

Limitation of liability

To the maximum extent permitted by applicable law, we will not be liable for any indirect, incidental, special, consequential, or exemplary damages, or for any loss of data, profits, or goodwill, or for any claims relating to Your Content (including its lawfulness, your rights to use it, or its loss, damage, or corruption), arising out of or relating to your use of or inability to use the Service, even if we have been advised of the possibility of such damages. To the same extent, our total aggregate liability arising out of or relating to these Terms or the Service will not exceed the amount you paid us for the Service in the twelve months preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, or any statutory rights you have as a consumer.

Indemnification

To the extent permitted by applicable law, you agree to indemnify and hold us harmless from any claims, damages, and reasonable expenses (including legal fees) arising from Your Content or from your breach of these Terms.

Termination

We may suspend or terminate your access to the Service, or revoke your License, if you materially breach these Terms. You may stop using the Service and uninstall it at any time. Upon termination for breach, the rights granted to you under these Terms, including any License, end immediately. Sections that by their nature should survive termination (including Your content, Feedback, Disclaimer of warranties, Limitation of liability, and Indemnification) will survive.

Governing law

These Terms are governed by the laws of the Czech Republic, without regard to its conflict-of-law rules. If you are a consumer, this choice of law does not deprive you of the protection of mandatory consumer-protection provisions of the law of the country in which you reside.

If you are a consumer and a dispute between us cannot be resolved directly, you are entitled to submit it for out-of-court resolution to the Czech Trade Inspection Authority (Česká obchodní inspekce, Štěpánská 796/44, 110 00 Praha 1, www.coi.cz; online submission at adr.coi.cz).

General

If any provision of these Terms is found unenforceable, the remaining provisions remain in full effect. Our failure to enforce any provision is not a waiver of it. You may not assign these Terms; we may assign them in connection with a merger, acquisition, or sale of assets. These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the Service.

Changes to These Terms

We may update these Terms from time to time by posting them on this page and updating the "Last updated" date. Updated Terms apply prospectively: to the Site, to new purchases, and to versions of the Service released after they take effect. They do not diminish the rights of a License you have already purchased — the versions it covers remain governed by the terms in effect at the time of your purchase. If you do not agree with updated Terms, stop using the Site and do not install further updates; you may continue using the versions your License covers under the prior terms.
