Privacy Policy

Effective from 9 August 2026. Version: 1.0

This notice has been prepared in accordance with Regulation (EU) 2016/679 of the European Parliament and of the Council (GDPR) and Act CXII of 2011 on the Right of Informational Self-Determination and on Freedom of Information.

We do not process special categories of data. A name at birth and a date of birth do not in themselves qualify as special category data under Article 9 GDPR. Please do not provide health, religious, political or other sensitive data in your questions — we do not ask for such data, and even if it is provided we will not use it for any other purpose.

3. Source of the data

We collect the data directly from the data subject, during registration and use of the service. In the case of a relationship analysis, the other person's data is provided by the user; the user is therefore responsible for ensuring that they are entitled to do so.

4. Data processors and recipients

The data controller uses the following data processors:

Data processorActivityData concerned

Electronic invoicingName, billing address, e-mail address, purchase details

Bank card details are processed exclusively by the payment service provider; the data controller neither sees nor stores them.

5. Transfers to third countries

When the analyses are produced and when certain technical services are used, data may be transferred outside the European Economic Area, primarily to the United States of America. The lawfulness of such transfers is ensured by an adequacy decision of the European Commission or by the standard contractual clauses adopted by the European Commission and concluded with the service providers.

6. Automated decision-making

By its very nature, the service generates text automatically with the assistance of artificial intelligence. However, this does not produce legal effects concerning the data subject or similarly significantly affect them, as the service is provided for informational purposes only. Automated decision-making within the meaning of Article 22 GDPR therefore does not take place.

7. Cookies and local storage

The application does not use marketing or analytics cookies. For its operation it uses only the browser's local storage (localStorage, sessionStorage), in which it stores the sign-in session, the current result and the pending question. This data remains in the browser, is deleted when you sign out or close the application, and does not require separate consent.

To confirm registration, the data controller stores a single-use, randomly generated identifier, which is deleted at the moment of confirmation.

8. Data security

The data controller transmits data over an encrypted connection (HTTPS), protects the database with access restrictions (row level security), and stores passwords solely as salted, one-way hashes — passwords cannot be decrypted. The administration interface is password protected, and authentication takes place exclusively on the server.

9. Rights of the data subject

You are entitled at any time:

You can send your request to info@opusnumerology.com. The data controller will comply with the request within one month at the latest, or, in justified cases, will inform you of an extension of this deadline.

If the account is deleted, the personal data and analyses belonging to the account are permanently erased, with the exception of data that the data controller is required by law to retain (in particular accounting documents).

10. Remedies

If you believe that your rights have been infringed in connection with the processing of your data, we ask you first to contact the data controller directly. You may also lodge a complaint with the supervisory authority or bring an action before the courts.
