2. Scope and acceptance of these terms

These terms apply to every visitor and user of the Opus Calculator application. By using the application, the User accepts these terms. If you do not accept them, please do not use the application.

3. Content and nature of the service

Opus Calculator is a free application for informational and educational purposes, which performs numerology calculations based on the name and date of birth provided by the User, and displays number meanings, personal cycles and lesson material.

The application is for entertainment and educational purposes only. The content displayed does not constitute legal, medical, financial, psychological or relationship advice, and is not a substitute for consulting a professional. The User is solely responsible for any decisions made on the basis of the content.

The entire calculation runs in the User's browser; the application sends no data to the Service Provider. For details, see the Privacy Policy.

4. No registration and no fees

Use of the application requires no registration, no user account and no payment of any kind. The Service Provider charges no consideration for the use of the application and creates no payment obligation for the User. Since no contract for consideration is concluded, the question of a right of withdrawal under Hungarian Government Decree 45/2014 (II. 26.) does not arise.

5. Obligations of the User

6. Liability

The Service Provider makes the application available "as is" and gives no warranty of continuous, error-free operation, nor for temporary unavailability of the application. The Service Provider is not liable for decisions arising from the interpretation or use of the application's content, or for their consequences. The Service Provider's liability is excluded to the fullest extent permitted by law; this does not affect liability for breaches committed intentionally or causing harm to human life, physical integrity or health.

7. Intellectual property

The application, its source code, texts, lesson material and design elements are the intellectual property of the Service Provider. Copying, reproducing, adapting or publicly republishing them without the Service Provider's prior written consent is not permitted. Private use of the application and personal use of the results is of course permitted.

8. Data processing

The application collects and transmits no personal data: the name and date of birth entered are processed and stored exclusively in the User's browser. Details are set out in the Privacy Policy.

9. Complaints handling and enforcement of rights

The User may submit a complaint to info@opusnumerology.com. The Service Provider will examine the complaint and provide a substantive written response within 30 days.

The European Commission's online dispute resolution platform is available at: https://ec.europa.eu/odr
