The public site stays static on purpose.
Science Wonders is a static, browser-run reference site. The accelerator, detector, and gravitational-wave models use local source data bundled with the site. There are no accounts, payments, analytics dashboards, advertising systems, or form submissions.
Current data processors
Cloudflare Pages
Cloudflare Pages hosts and serves the static site. Cloudflare may process standard request metadata such as IP address, user agent, URL, timestamp, and security signals to deliver files, apply HTTPS, and protect the edge network. Science Wonders does not use Cloudflare analytics inside the page.
External source sites
Science Wonders links to public source material from institutions such as CERN, LIGO, Virgo, KAGRA, EGO, and related documentation sites. Those links open outside Science Wonders. Once you follow an external source link, that institution's own privacy and data-processing terms apply.
Browser storage
The site may store a theme preference in your browser through localStorage. That value is used to restore the light, dark, or automatic theme choice. It is not sent to a Science Wonders account system because there is no account system.
Data-processing boundary. There is no production database of visitors, no user profile, no payment processor, and no email-marketing subprocessor for this site. The models run in the browser from static files. The DPA-style disclosure here is intentionally short because the service list is intentionally short.
