Privacy Policy

No ordinary account

GreenHalos does not require registration and does not maintain a server-side aurora-viewing profile. Language, hemisphere, layer, reduced-data, reduced-motion and catalogue-location identifiers can be stored locally in your browser. GreenHalos cannot recover these preferences after you clear them.

Optional location

If you choose Use my location, the browser asks for permission. GreenHalos uses the coordinate to calculate local sky conditions and select relevant forecast data.

GreenHalos is designed not to retain precise coordinates on its server. If a backend cloud lookup is needed, coordinates are minimised or rounded and retained only as required for the forecast cache.

Technical and security data

Cloudflare processes ordinary network requests to deliver and protect the service. GreenHalos minimises custom logs. Minimal security records are normally retained for seven days or for up to thirty days during a documented incident.

GreenHalos uses Cloudflare Web Analytics to measure aggregate page visits and real-user performance. The cookie-free beacon sends page and navigation-performance measurements to the first-party /cdn-cgi/rum endpoint on greenhalos.com. Cloudflare reports aggregate dimensions such as page path, referring site, approximate country, device type, browser and operating system; GreenHalos does not use this service for cross-site or person-based tracking.

Operational and research data are retrieved through scheduled backend processes. Ordinary visitors do not contact NOAA, NASA or MET Norway directly through GreenHalos.

Advertising, transfers and rights

GreenHalos does not currently display third-party advertising and does not use Google Analytics, advertising pixels, session replay or cross-site tracking. Cloudflare Web Analytics is the only visitor analytics service currently enabled and is described above.

ZENIT GROUP S.A.S. is established in Colombia. Cloudflare can process technical delivery and security data internationally when providing the service, subject to its applicable privacy and data-protection terms. Depending on applicable law, you may have rights to access, correct, erase, restrict or object to processing, request portability, withdraw consent or complain to a supervisory authority.
