Server logs
Like almost every website, the web server records standard access logs (IP address, user agent, requested URL, timestamp). They are used for security, debugging, and the aggregate visitor counter shown in the footer. The published counter contains only aggregate totals - never IPs or identifiers.
Local storage
Your theme preference (light/dark/auto) is stored in your browser's localStorage under the key 'exorbit-theme'. It never leaves your device. A service worker caches static assets for speed and offline reading.
Self-hosted assets
Fonts, math rendering (MathJax), icons, and 3D libraries are served from exorbit.space itself, so page views do not trigger requests to third-party CDNs.
Live data snapshots
News headlines, satellite summaries, and ephemeris data shown on pages are fetched server-side and republished as static JSON. Your browser only talks to exorbit.space.
Live chat
If you use the live-chat widget where available, the messages you type are transmitted to the site's own chat backend so the team can respond. Do not share sensitive personal data in chat.
Subdomains
Apps hosted on subdomains (for example the Grade 4 space course at g4.exorbit.space, which offers optional accounts) publish their own notices in-app.
