Location
Readings are location-based, and here is exactly how location works:
- By default we do not ask for your location. We pick a representative city from your device's timezone setting — no permission prompt, nothing sent anywhere.
- If you search a city, the text you type is sent to a geocoding service (Open-Meteo for suggestions, OpenWeatherMap for lookup) to turn it into coordinates.
- If you tap the location button, your browser asks for permission first. The coordinates are used in your browser to compute the sky and are sent to OpenWeatherMap to fetch current weather and a place name.
- Storage: your chosen location (coordinates and place name) is saved in your browser's
localStorageso your next visit opens where you left off. It is not stored on our servers — the site is static and has no database.
Preferences
Your theme choice (light/dark) and, as planner features grow, your saved filters are stored in localStorage on your device. Clearing your browser storage removes them.
Analytics
We currently run no analytics — no page-view trackers, no advertising pixels, no fingerprinting. If we add privacy-respecting, cookieless analytics later, this policy will be updated first and the tool will be named here.
Email (waitlist and daily briefings)
If you give us your email address for the Premium waitlist or a daily briefing, we store it with our email provider, use it only for what you signed up for, and every message includes an unsubscribe link. We never sell or share addresses.
Third-party services
- Cloudflare Pages hosts the site and, like any host, keeps standard server logs (IP address, request path) for security and operations.
- OpenWeatherMap receives coordinates (and city searches) to return weather and place names. Their policy.
- Open-Meteo receives city-search text to return suggestions. Their terms.
- jsDelivr CDN serves the astronomy library file; your browser requests it like any script file.
Children
The site is a general-audience almanac and is not directed at children under 13. We do not knowingly collect personal information from anyone.
