Is my birth data stored?

No. All computation happens locally or via stateless server-side ephemeris. Birth data is never stored, sold, or shared.

What's the difference between Vedic and Western astrology?

We support both. Vedic uses sidereal zodiac (Lahiri/KP), Western uses tropical. You can switch in settings.

How accurate are the predictions?

Our engine aligns 81.9% of top-30 dasha windows across 3,445 permitted event records from 570 charts; a separate 793-event chart-disjoint blind test scores 81.8%. Exact-day and year-placeholder results are reported separately.

What is ayanāmśa and which should I use?

Ayanāmśa corrects for precession. Lahiri is India's government standard. KP practitioners should select KP.

Can I use this for professional consultations?

Yes. Pro tier includes export, PDF reports, and the full rules library. Many practitioners use it as a reference.
