Terms of Use

Effective from: September 21, 2026 | Version: 1.1 | Česká verze

This is an English translation of the Terms. The Czech version is legally binding and prevails in the event of any discrepancy between the language versions (Art. 15.2). Read the Czech version.

1. Introductory provisions

1.1. These terms of use (the “Terms”) govern the mutual rights and obligations of the operator and the user when using the Kytario web application available at https://kytario.com (the “Service”).

1.2. The Service is operated by the natural person Robin Zounar, residing at Jundrov č.ev. 845, Brno-Jundrov, 637 00 (the “Operator” or “we”). The Operator runs the Service as a non-commercial private project outside the scope of any business activity.

1.3. A user is any natural person who uses the Service, whether as a registered user with a user account or as a visitor without registration (the “User” or “you”).

1.4. By registering a user account, or merely by using the Service without registration, you agree to these Terms and undertake to comply with them. If you do not agree with the Terms, please do not use the Service.

1.5. The processing of personal data is governed by a separate document, the Privacy Policy, which forms an integral part of the relationship between you and the Operator.

2. Description of the Service

2.1. The Service is an online tool for creating, managing and sharing digital songbooks with chord notation, creating songs, playlists and projects, and generating PDF documents from them.

2.2. The Service is provided “as is” (see Art. 9 and 10). The Operator may at any time change the scope, form and features of the Service, or restrict or discontinue its provision.

2.3. The Service is provided free of charge and the Operator does not display paid third-party advertising on it. The Service is a non-commercial community project; the Operator does not organise or promote content in the Service for profit-making purposes. Any voluntary contributions from supporters serve exclusively to cover the operating costs of the Service and give rise to no entitlement to any performance beyond ordinary use of the Service. Any acknowledgement of supporters in the Service is a voluntary expression of gratitude to which there is no entitlement.

2.4. The Service may contain links to third-party websites or projects (for example community or partner projects). The Operator is not responsible for the content or availability of those websites.

3. User account

3.1. Full use of the Service requires registering a user account. Registration and sign-in take place through a Google account.

3.2. A user account may only be created by a person who has reached the age of 15. By using the Service you declare that you meet this condition.

3.3. We obtain your account details (name, email address and profile picture) from your Google account. These details cannot be entered or edited in the Service; you manage them directly in your Google account. Details of how they are processed can be found in the Privacy Policy.

3.4. Access to your account in the Service is tied to your Google account. You are responsible for the security of your Google account and for all activity carried out under your account in the Service. Please notify us without delay of any unauthorised use of your account at info@zounar.me.

3.5. The Operator may cancel or restrict a user account, in particular if the User breaches these Terms, applicable law or the rights of third parties.

4. Rules for using the Service

4.1. You undertake to use the Service in accordance with these Terms, applicable law and good morals.

4.2. When using the Service, you must not, in particular:

• upload, store, share or otherwise make available content for which you do not have the necessary copyright or licence rights or the consent of the rights holders; for song lyrics and chords this applies especially when sharing them publicly (see Art. 6);
• upload content that is unlawful, defamatory, hateful, misleading or otherwise objectionable;
• compromise the security, availability or integrity of the Service, circumvent its technical restrictions, or gain unauthorised access to other people’s accounts or data;
• burden the Service with automated requests (bots, scraping) beyond ordinary use without our consent;
• use the Service to send unsolicited communications (spam) or malicious code;
• upload pornographic images, images of a sexually explicit nature or images depicting nudity;
• upload advertising, commercial communications or other promotional content unrelated to the purpose of the Service;
• create accounts or projects, or upload content, in bulk without genuinely using the Service (for example for the purpose of placing links).

4.3. A breach of these rules may result in the restriction, temporary blocking or cancellation of the account and, where applicable, in liability for any damage caused.

5. User Content

5.1. “User Content” means all content that you upload, submit or create in the Service - in particular songs, lyrics, chords, titles, songbooks, playlists, projects and images.

5.2. All User Content remains yours, or remains the property of the respective rights holders. The Operator claims no ownership of it.

5.3. By uploading User Content, you grant the Operator a free, non-exclusive licence to store, reproduce, display, process and make it available to the extent necessary for operating and providing the Service (for example to display your songbook, share it according to the settings you choose, or generate a PDF). This licence lasts for as long as the content is stored in the Service and expires upon its deletion, except for backups kept for a reasonable period. The licence also includes the Operator’s right to involve third parties in operating the Service (in particular providers of technical infrastructure, PDF generation and artificial intelligence processing) to the extent necessary to provide the Service.

5.4. You bear full responsibility for the User Content you upload to the Service, including for being entitled to upload it and make it available to others in accordance with Art. 6.

5.5. By uploading User Content, you represent and warrant that:

• (a) you are its author, or you have all the rights, licences and consents necessary to upload it to the Service, process it and make it available to the extent you choose in the Service (including any public sharing);
• (b) the User Content does not infringe copyright, related rights, trademarks, personality rights or any other rights of third parties;
• (c) you are entitled to grant the licence under Art. 5.3.

5.6. If you make User Content publicly available, you grant other Users a non-exclusive, free permission to use it within the Service in the ways the Service allows (in particular displaying it, including it in their own songbook, playlist or project, and generating a PDF for personal use). This permission does not cover use outside the Service and expires when the content is removed from the Service; songbooks and documents already created are not affected.

6. Copyright and third-party content

6.1. Song lyrics and chords may be copyright works protected by Czech Act No. 121/2000 Coll., the Copyright Act. Responsibility for obtaining the necessary permissions to upload, store and share such content lies solely with the User who uploaded it. This also applies to rights administered by collective management organisations (e.g. OSA or DILIA) - obtaining any licence for making the content available to the public is the obligation of that User.

6.2. In relation to User Content, the Operator acts as a provider of a hosting service within the meaning of Article 6 of Regulation (EU) 2022/2065 of the European Parliament and of the Council on a Single Market for Digital Services (Digital Services Act). In the Service, User Content is associated with the project that uploaded it, and the Service shows the name of that project with the content; the Operator is neither its author nor its publisher. The Operator does not actively monitor User Content, does not select it or organise it for profit-making purposes, and is not liable for it, unless the law provides otherwise; however, if it becomes aware of its unlawfulness, it will remove it or disable access to it without delay. The automatic conversion of song text using artificial intelligence (Art. 7) is a purely automated function triggered by the User and does not constitute content review or editorial oversight by the Operator over User Content.

6.3. The Operator provides a mechanism for notifying content that you consider unlawful or infringing the rights of third parties (a notice within the meaning of Article 16 of Regulation (EU) 2022/2065 - Digital Services Act). Send the notice to info@zounar.me and include:

• a sufficiently precise identification of the content concerned (e.g. a link / URL);
• an explanation of why the content is unlawful or infringes rights and, in the case of an alleged infringement of rights, where possible, evidence of your entitlement;
• your contact details;
• a statement that the information provided is accurate and complete.

We will confirm receipt of an electronically submitted notice without undue delay. We will assess a properly submitted notice without undue delay; content that appears to be unlawful or infringing will be removed or disabled. We will inform both the notifier and the affected User of the outcome of the assessment and the reasons for our decision. We handle notices in a timely, diligent, impartial and non-arbitrary manner; decisions on them are not taken solely by automated means (Art. 6.7).

6.4. The Operator may remove or disable access to any User Content that is contrary to these Terms or the law, even without prior notice. We inform the affected User of the removal or disabling of content and of the reasons for it, unless the law provides otherwise. The obligation to inform does not apply to deceptive high-volume commercial content (Article 17(2) of Regulation (EU) 2022/2065). If you disagree with a decision, you may contact the Operator at info@zounar.me; the Operator will consider your submission. This is without prejudice to your right to bring the matter before a court or, if you are a consumer, before an out-of-court dispute resolution body under Art. 13.2.

6.5. If a third party (in particular a copyright holder or a collective management organisation) asserts a claim against the Operator on account of your User Content, you undertake to reimburse the Operator for the costs reasonably incurred in dealing with that claim, including reasonable costs of legal representation and any damages awarded. This is without prejudice to consumer rights arising from mandatory provisions of law.

6.6. The Operator may restrict or cancel accounts that repeatedly upload content infringing the rights of third parties.

6.7. The Operator does not pre-approve or systematically check User Content (Art. 6.2). It reviews content on the basis of notices under Art. 6.3, or if it otherwise becomes aware of a possible breach of the Terms or the law; it takes decisions to remove content or restrict an account after an individual assessment and does not take them solely by automated means. The Operator may automatically standardise chord notation and other elements of the Kytario format across the Service; this does not change the text of User Content. When content is saved, the Service automatically checks whether the notation conforms to the Kytario format and rejects notation containing format errors; this check concerns solely the form of the notation, not the content of the text. The Service also automatically evaluates the technical quality of the notation (formatting of chords and sections) and allows Users to sort content by it. This evaluation assesses only the notation format, not the content of the text, and does not affect the default order of content or its availability.

6.8. If the Operator becomes aware of User Content indicating the commission of a criminal offence that threatens the life or safety of a person, it will notify the law enforcement authorities without delay; in doing so it fulfils its obligation under Article 18 of Regulation (EU) 2022/2065 and its obligations under Sections 367 and 368 of Czech Act No. 40/2009 Coll., the Criminal Code. It will also remove such content from the Service or disable access to it. For the purposes of the law enforcement authorities, the Operator retains only identification and operational data (in particular the account identifier, timestamps, IP address and the address of the content concerned), for as long as necessary for that purpose. The Operator does not separately retain the content itself for these purposes; it will make it available to the authorities only upon their lawful request.

7. Features using artificial intelligence

7.1. The Service offers a feature for automatically converting pasted song text into the Kytario format using artificial intelligence.

7.2. When you use this feature, the text you paste is sent for processing to the AI service provider (Anthropic, USA). Do not use this feature for content you do not wish to have processed in this way.

7.3. The output of the AI feature is generated automatically and may contain errors. We recommend checking it before further use. The Operator is not responsible for the accuracy or completeness of automatically generated content.

8. The Operator’s intellectual property

8.1. The Service as a whole, its source code, design, logo, the name “Kytario” and other elements are protected by intellectual property rights and belong to the Operator, except User Content (Art. 5.2), unless stated otherwise.

8.2. These Terms do not grant you any rights to these elements beyond ordinary use of the Service in accordance with its purpose.

8.3. For the avoidance of doubt, you may link to the Service, share links to content in the Service and use the name “Kytario” for the purpose of referring to or recommending the Service. When links to content in the Service are shared, the name and logo of the Service may be displayed; this does not give you any rights to these marks.

8.4. Without the Operator’s prior written consent, you are in particular not entitled to:

• use the name or logo of the Service in a way that creates the impression of an association, partnership or endorsement by the Operator where no such relationship exists;
• modify the logo of the Service or use it in your own materials or for your own commercial purposes;
• register confusingly similar marks or domain names.

9. Availability of the Service

9.1. The Operator makes reasonable efforts to keep the Service available and functional, but does not guarantee its uninterrupted availability or error-free operation.

9.2. The Operator may temporarily restrict or interrupt the Service, in particular for maintenance, updates, security measures or reasons on the part of third parties (for example hosting providers).

10. Limitation of liability

10.1. The Service is provided “as is” and “as available”, without any warranties beyond the mandatory provisions of law.

10.2. To the extent permitted by law, the Operator is not liable for damage arising in connection with the use of the Service, in particular for loss of data, loss of profit or damage caused by unavailability of the Service or by the actions of third parties. We recommend backing up important content.

10.3. This is without prejudice to consumer rights arising from mandatory provisions of law; nothing in these Terms limits any liability that cannot be limited under the law.

11. Termination of use and account cancellation

11.1. You may stop using the Service at any time and request the deletion of your account and related data by following the procedure described in the Privacy Policy.

11.2. The Operator may discontinue the Service or cancel your account for the reasons set out in these Terms; where possible, we will inform you of the discontinuation of the Service reasonably in advance.

12. Personal data protection

12.1. Information about what personal data we process and how can be found in the Privacy Policy.

13. Governing law and dispute resolution

13.1. These Terms and the relationship between you and the Operator are governed by the laws of the Czech Republic, in particular Act No. 89/2012 Coll., the Civil Code. If you are a consumer, this choice of Czech law does not deprive you of the protection afforded to you by those provisions of the law of the country of your habitual residence that cannot be derogated from by agreement.

13.2. If you are a consumer, you have the right to the out-of-court resolution of a consumer dispute. The body competent for out-of-court dispute resolution is the Czech Trade Inspection Authority (https://www.coi.cz).

14. Changes to the Terms and their effect

14.1. The Operator may change these Terms, in particular in response to changes in the Service or in the law. The current version is always available on this page.

14.2. We will inform you of material changes in an appropriate manner (for example by email or by a notice in the Service), and in that case we may ask you to consent again to the updated version. If you do not agree with a change, you may stop using the Service at any time free of charge (Art. 11).

15. Final provisions

15.1. If any provision of these Terms is or becomes invalid, ineffective or unenforceable, this does not affect the validity and effectiveness of the remaining provisions.

15.2. The Terms are available in Czech and English. In the event of any discrepancy between the language versions, the Czech version prevails. These Terms are available to you at any time on this page.

15.3. The point of contact under Articles 11 and 12 of Regulation (EU) 2022/2065 is the email address info@zounar.me; communication is possible in Czech and English.
