Sources and responsibility
Transparency
The resources used by the card, how information is processed, and the role of artificial intelligence and human review.
Last updated: August 2026
Summary
The Digital Business Card is a personal and professional presentation of Alfonso Rodríguez. It organises authorship, contact and project information within a visual experience reviewed and published under human responsibility.
It is not an official service, a data platform, an emergency system or a professional advisory tool.
How it was created
The project was developed through concept definition, structuring, design, programming, bilingual review, mobile and desktop testing, and version validation before publication.
Resources and technical services
- Netlify: technical hosting and distribution of the experience.
- Browser and device: provide the date, time, language and functions such as sharing or installing the PWA when available.
- Local resources: Earth and Moon textures, procedural starfield, visual representation of the Sun, icons, social preview image and other files included in the project.
- External links: lead to published projects, X, LinkedIn, email and identified official resources.
The card does not query an astronomy API. Earth lighting, the Sun’s approximate visual direction and the Moon’s approximate orbital position are calculated locally from system date and time. The visible lunar phase is derived from Sun–Earth–Moon geometry. The Moon follows a complete visual orbit around Earth, but sizes and distances are not to scale, and the projection, depth and visual radii are adapted to the card composition.
Data, calculation and representation
- System data: system date and time and browser language.
- Derived calculations: approximate subsolar point, Earth day/night lighting, approximate ecliptic longitudes of the Sun and Moon, the Moon’s visual orbital position and derived lunar phase.
- Visual representation: peripheral sunlight, procedural starfield, a complete visual lunar orbit, and scale, depth and projection adapted to the card design.
The scene is not a certified astronomy simulator and does not reproduce distances, sizes, orbital inclinations or every physical phenomenon to scale.
Use of artificial intelligence
Artificial intelligence tools were used as support for programming, structuring, research, review, translation, testing and documentation.
The card does not run a generative model during the visit, does not converse with the visitor and does not generate personalised answers or recommendations in real time.
Selection, review, interpretation and publication remain under the supervision and responsibility of Alfonso Rodríguez.
Privacy and permissions
The card does not request geolocation, camera, microphone or other sensitive permissions. It contains no forms, analytics or first-party cookies. The PWA and Service Worker may store technical resources in the browser cache to support installation and loading.
The full explanation is available in the Privacy Policy.
Limitations
- Astronomical calculations are approximate and intended for visual representation.
- PWA installation and sharing functions depend on the browser and operating system.
- The cache may temporarily retain an earlier version until the browser updates its resources.
- External links and services depend on the availability and policies of their respective providers.
