Dark Sky Planner uses the details you provide, such as observing location, dates, and observing window, to generate your plan. Location search is powered by OpenStreetMap Nominatim data, and the map picker uses Leaflet with third-party map tiles. The app does not require an account.

To help improve the planner, the site uses Google Tag Manager and Google Analytics. These tools may use cookies or similar browser storage. Analytics may include general usage information and coarse observing-location details such as city, region, country, and timezone, but it does not include exact coordinates, exact dates, raw search text, or full location names. Analytics data is not sold or used for unrelated commercial purposes.
