Privacy Policy
FastAstro.us is a static observational astronomy reference site. All interactive calculators and catalog searches execute locally in your browser without transmitting your inputs to our servers.
1. Local Browser Execution & Query Stripping
When you use our distance modulus, eyepiece magnification, limiting magnitude, angular separation, coordinate converter, or surface brightness calculators—or filter objects on our search page—all computations happen entirely in client-side JavaScript. Our analytics configuration strips non-campaign query parameters before sending page-view events so calculator inputs are never logged.
2. Your Privacy Choices & Consent Mode v2
For visitors in the European Economic Area (EEA), the United Kingdom, and Switzerland, analytics and advertising storage default to denied prior to any Google tag loading. Outside those regions, if your browser sends a Global Privacy Control (navigator.globalPrivacyControl === true) signal, ad_user_data and ad_personalization are automatically set to denied.
3. Privacy Inquiries
