3.1. Calculations for unregistered users ("Guests"): The User understands and accepts that calculations are performed exclusively on the client-side (in the browser) using URL hash parameters (after the hash symbol #). Technically, this data is not transmitted to the Owner's web server, nor is it retained by us.

    • To guarantee privacy, the browser's address bar is automatically cleared using the replaceState method immediately after the calculations are loaded on the screen.
    • To share the results obtained, the User undertakes to exclusively use the integrated "Share" button, which dynamically generates a hash link from the active screen state.

3.2. Personal Area (Registered Users): When saving calculations in the Personal Area, the data is recorded in a secure database.

    • Activation Procedure (Double Opt-In): Upon creating an account, it is registered in an inactive state. An email with a confirmation link will be sent to the address provided by the User. Logging in and using the functions of the Personal Area will only be permitted after clicking on the link. Inactive accounts will be automatically and irreversibly deleted from the system 14 (fourteen) days after the email is sent.
    • Sharing via UUID: When using the calculation sharing feature, the Platform generates a unique link with an anonymous key such as https://qichart.com/?share=UUIDv4, which does not contain any personal data (such as name or date of birth) in the URL string.
    • SEO Protection: The data of the share=UUID link is protected against search engine indexation (Google, Bing) through technical HTTP headers and meta tags (noindex, nofollow, noarchive, nosnippet).
    • Access Control: Access to the calculation via the UUID link is provided by the server only if the User has manually changed the map's status to "Public" in their Personal Area.

3.3. Third-Party Data: When entering the birth data of third parties (friends, family members, acquaintances) into the Platform to perform calculations, the User warrants under their sole responsibility that they have obtained prior, express, and informed consent from such persons for the processing of their data.
