You settle yourself through the senses: food, comfort, routine, one unhurried evening.
You register as warm and slightly luminous; people assume confidence even on your worst day.

Is it free?
Yes. Every calculator and guide is free, with no account and no paywall. Charts are computed in your own browser, so there is nothing to sell you.
How accurate are the charts?
Planetary positions come from a professional-grade astronomical engine, tested automatically against NASA JPL reference data to within a few hundredths of a degree. Time zones are resolved against the complete historical database, including pre-1922 local mean time. Every chart lists its computed UTC instant, so you can check it.
What happens to my birth data?
The calculation runs entirely in your browser. Saving a chart stores it on this device first; if you choose account sync, your saved charts upload to your Supabase account so they can follow you across devices.
What is Astrofolio?
Astrofolio is the optional companion app for the Twelve. The astrology tools here stay free and private; Astrofolio is where your saved charts and the signs you care about become a cosmic identity you keep — shelves, share cards, and a profile. It starts on this device, free, with account sync when you want it.
What is the Registry?
The collector’s wing of the site: a museum-style catalogue of the twelve signs as canonical records, with its own archive and thesis. It is deliberately separate from the astrology tools. Visit it if collecting interests you, or ignore it entirely.
