Privacy

What is collected

Nothing. There are no accounts, no sign-up, no contact forms and no comment system. No personal data is requested, stored or processed.

Cookies and tracking

No cookies are set. No analytics package is loaded. There are no tracking pixels, no fingerprinting scripts, no advertising network and no third-party embeds of any kind. The pages request no external resources at all: no fonts, no scripts and no images from other domains. You can confirm this in your browser's network inspector.

One item is stored locally on your own device: your light or dark theme preference, kept in the browser's local storage so the site does not flash the wrong theme on your next visit. It never leaves your device and is not readable by anyone else. Clearing site data removes it.

Your calculations

Every figure on this site is computed by JavaScript running inside your browser. Constellation parameters are never sent to a server, because there is no server to send them to beyond the static file host. Configurations you share as a link contain only the parameter values you chose, in the address itself, and are shared only if you choose to send that address to someone.

Hosting logs

Static files are served by a hosting provider, which like any web server may keep short-lived operational logs containing request details such as IP address, user agent and requested path. These are the host's standard operational records rather than something this site collects, analyses or uses to build any profile.

Changes

If this ever changes, for example if a privacy-respecting usage counter is added, this page will say so plainly before it happens rather than after.
