The short version
COSMOS does not collect your personal information. We do not require you to create an account. We do not sell data. We use privacy-preserving analytics that do not track you across sites.
What we collect
- Anonymous page views — via Cloudflare Web Analytics. No cookies, no cross-site tracking, no fingerprinting.
- Location (optional) — only if you grant browser permission for Tonight's Sky. We do not store or transmit your coordinates to any server. All calculations happen in your browser.
- Session settings — sound on/off, motion preference. Stored in your browser's sessionStorage only. Gone when you close the tab.
Third-party services
COSMOS fetches data from these external APIs. Their privacy policies apply to their services:
- NASA APIs (api.nasa.gov) — public data, no personal info sent
- Open Notify (open-notify.org) — ISS position, no personal info sent
- TheSpaceDevs / Launch Library 2 — launch data, no personal info sent
Cookies
We use one functional cookie: whether you've seen the intro animation. This is strictly necessary for site function, not tracking. No consent banner needed under GDPR for functional-only cookies.
