FAQ

Frequently Asked Questions

Is Astro Engine free? ▾

Yes! Astro Engine offers a generous free tier that includes natal chart generation, daily horoscopes, and up to 5 saved charts. For advanced features like synastry, predictive tools, traditional techniques, and API access, we offer Pro ($9/mo) and Premium ($29/mo) plans.

How accurate are the calculations? ▾

Astro Engine uses the Swiss Ephemeris, the gold standard for astronomical calculations. Our calculations achieve accuracy to 0.001 degrees of arc, covering planetary positions from 5401 BC to 5399 AD. Every result is cross-verified against established ephemeris data.

What techniques are supported? ▾

We support 66 calculation modules spanning both modern and traditional astrology: natal charts, synastry, composite and Davison charts, transits, secondary progressions, solar arc directions, solar/lunar returns, zodiacal releasing, annual profections, firdaria, decennials, sect analysis, essential dignities, fixed stars, Arabic lots, Hamburg School (TNPs and 90-degree dial), and much more.

Can I use the API for my own app? ▾

Absolutely. Our REST API provides 121 well-documented endpoints with clean JSON responses. Pro and Premium plans include API access with generous rate limits. You can integrate natal chart generation, transit calculations, synastry analysis, and all other features directly into your own applications.

How is my data protected? ▾

Your privacy is a top priority. All data is encrypted in transit (TLS 1.3) and at rest. We never share or sell your birth data. You can delete your account and all associated data at any time. Our servers are hosted in secure, SOC 2-compliant facilities.

What's the difference between Free and Pro? ▾

The Free plan gives you natal charts, daily horoscopes, and 5 saved charts. Pro unlocks synastry and composite charts, predictive tools (transits, progressions, returns), API access, and unlimited saved charts. Premium adds traditional techniques (zodiacal releasing, firdaria, decennials), Hamburg School, electional astrology, and priority support.
