Privacy Policy

FastCosmos is a static educational astrophysics and cosmology reference. Interactive calculators run locally in your browser.

Calculator Inputs & Local Computation

Parameters entered into our Interactive Explorers or Search are evaluated in your browser. When analytics are enabled, query parameters carrying calculator inputs are stripped before page views are recorded.

Analytics & Regional Consent Defaults

We use Google Consent Mode v2. For visitors in the European Economic Area (EEA), the United Kingdom, and Switzerland, all advertising and analytics storage parameters (ad_storage, ad_user_data, ad_personalization, and analytics_storage) default to denied prior to any tag loading. Outside those regions, if your browser sends a Global Privacy Control (Sec-GPC: 1 / navigator.globalPrivacyControl === true) signal, ad_user_data and ad_personalization are automatically denied.

Your Privacy Choices

You can control cookies through your browser settings, enable Global Privacy Control (GPC), or contact us at contact@fastcosmos.us with any privacy questions.
