Privacy

Astro Radar has no accounts, no sign in, no cookies, no advertising and no analytics or tracking scripts. The page's security policy lets it load scripts only from this site.

What stays in your browser

Only these, in your browser's local storage on this device: your home ZIP code and its place name, the reminders you set, and whether Nerd mode is on. They are never sent to Astro Radar. To remove them, clear this site's data in your browser's settings. A copy of the site's files and the last launch list is also kept on your device so the page works offline.

What leaves your browser

• Your ZIP code never does. The page looks it up in a table of US ZIP codes it downloads from this site.
• The National Weather Service (weather.gov) receives the latitude and longitude of your ZIP code's center, rounded to about a kilometer, to send back the forecast sky cover at launch time.
• The launch list comes from this site and, when the site uses one, from its own live feed server. Those requests carry nothing about you beyond what every web request carries.
• Live from space and Space news: while one of those pages is open, your browser asks NOAA's Space Weather Prediction Center (services.swpc.noaa.gov), NASA EONET (eonet.gsfc.nasa.gov) and the Spaceflight News API (api.spaceflightnewsapi.net) for their latest public data. Those requests carry nothing about you beyond what every web request carries. The ISS's next pass over your saved ZIP code is worked out in your browser; your ZIP code is not sent.
• Share to Astro opens astrosocial.io with the launch you chose (its name, time and link), only when you press it.
• Watch and other links open the provider's or streaming site, only when you press them.

The site is hosted on GitHub Pages, and the live feed, when used, on Cloudflare. Like any web host they receive the usual details of each request, such as your IP address and browser; Astro Radar adds no tracking to them.
