Borealis Radar is a free, real-time aurora visibility tool. We collect the minimum data needed to make the forecast work and nothing more. This page explains what we use, what we store, and what we don't.
Location data
- If you grant browser geolocation permission, your coordinates are used only to fetch your local weather and aurora forecast. Coordinates are sent to our server for that single API call and are not logged or stored.
- If you deny location, the radar still works globally — no fallback tracking is performed.
- You can revoke geolocation at any time in your browser settings.
Feedback form
- The feedback form is optional. If you submit it, your message is delivered to the maintainer via email (Resend.com).
- Email address is optional — provide it only if you want a reply. We do not add it to any mailing list.
Server logs
- Standard request logs (IP, user agent, timestamp, path) are retained for security and abuse prevention. They are not shared with third parties.
- Cloudflare sits in front of the site as a CDN and DDoS shield; their privacy practices apply to traffic at the edge — see Cloudflare's privacy policy.
Cookies & tracking
- No analytics, no ad networks, no tracking pixels.
localStoragestores your language preference and last-known location only — locally on your device, never sent to us.
Third-party services
- NOAA SWPC & OpenWeatherMap — space weather and cloud cover data sources (server-side calls).
- Leaflet / OpenStreetMap — map tiles. Your IP is visible to OSM tile servers when tiles load.
- Google Fonts — fonts loaded from Google's CDN.
- Cloudflare — CDN and edge protection.
- Resend — transactional email delivery for the feedback form (only if you submit it).
