Coordinates and tool inputs

Location presets, manually entered coordinates, the selected date and time zone, time-slider position and checklist choices are processed within this page. The site does not submit those values to a server, put them in the address bar or add them to external links.

We do not request browser geolocation, camera, microphone, contacts or account access. We do not create accounts. Tool choices are not saved in cookies or local storage; reloading or closing the page resets them. A downloaded plan is a text file saved through your browser to your device, not uploaded to this site.

What a page visit still sends

Loading any website involves ordinary requests to its host. This site serves HTML, scripts, styles, photographs, licenses and a small orbital snapshot from its own domain. The hosting provider can receive normal request information such as your IP address, user-agent, requested URL and request time, and may keep access/security logs under its own policies. This site does not claim that hosting logs are absent or prescribe a retention period we have not verified.

Sun, Moon and station calculations take place locally after those files load. Fonts use your device’s system fonts. We do not embed remote maps, videos, social widgets, third-party fonts or external astronomy APIs.

No analytics or advertising scripts

The current version includes no analytics tags, advertising tags, tracking pixels or site-set cookies. There is no behavioral advertising or cross-site visitor profiling implemented by this site. No cookie banner is shown because this implementation does not set nonessential cookies or load those services.

If advertising, analytics, forms or other external services are added later, this statement must be reviewed before those services go live and appropriate consent or other controls must be implemented where required. This is a description of today’s build, not a blanket promise about future versions.

Some sources and reading suggestions link to independent websites, such as NASA and CelesTrak. Those sites are not loaded until you follow the link, and their own privacy policies apply. Ordinary browser behavior may send them a referrer identifying this site. We do not attach your planner inputs or coordinates to those links.

Security and privacy also depend on your browser, extensions, network and device. The red-light color button changes only the page’s appearance; it does not alter device settings or privacy permissions.
