Privacy

Ásar bardagi sets no cookies and loads no third-party scripts, fonts, images or trackers; everything, including photos and the astronomy library, is served from this site. Links to other sites take you to those sites, which have their own policies.

Your location

"Use my location" asks your browser for your position and computes the sky on your device with code served from this site. Your location is never sent to us or to anyone else. The page's security policy only allows it to talk to this site, and the calculation needs no network at all. If you tick "Remember on this device", the rounded coordinates are kept in your browser's local storage, where only this site's pages on your device can read them; untick it or clear your browser's site data to remove them. Your night-vision and clock preferences are stored the same way.

If this ever changes, for example if advertising or affiliate links are added, this page will say so before it happens.

Server logs

Like almost every website, the server keeps a log of requests: the time, the page requested, the referring page, the browser's user-agent string, and a shortened network address (the last part of the IP address is removed before anything is written, so the log cannot point to one connection). The log is used only to count visits and to stop abuse, is never shared or sold, and is deleted after 30 days. The legal basis under the GDPR is legitimate interest in running and securing the site.

The hosting proxy in front of this site (measured 2026-10-26): successful requests are not logged there. Requests that fail at the proxy are recorded with the visitor's IP address and browser user-agent, with cookies and authorization headers redacted, and are currently kept until the proxy is restarted. A retention limit for those records is under review.
