About Soulio

Soulio creates personalized birth chart, numerology and compatibility readings. Our goal is simple: accurate calculations and clear, thoughtful texts that help you reflect on yourself — without fatalism, fear or subscriptions.

Who is behind Soulio

Soulio is operated by MAXX CICLO LTDA (CNPJ 42.153.960/0001-31), a technology company registered in Brazil since 2021. You can reach us at support@soulio.site.

How we calculate your birth chart

Planet positions are calculated with an astronomical model (astronomy-engine) and checked against the Swiss Ephemeris, the reference used by professional astrologers: in our tests, the positions differ by less than 0.01°. We use the tropical zodiac, Placidus houses (equal houses at extreme latitudes), the true lunar node and the mean Black Moon Lilith. Historical time zones and daylight saving time are applied automatically for your city.

How we calculate numerology

We use the Pythagorean system, the most widely used in the world, and keep the master numbers 11, 22 and 33. Your core numbers come from your full name at birth and your date of birth.

Where the texts come from

Every interpretation on Soulio was written specifically for Soulio, based on traditional astrological and numerological meanings, in English, Spanish, Portuguese and French. Readings describe tendencies and potentials — never a fixed destiny.

Your data

Free readings are calculated in your browser, so your birth data is not sent to us. For paid reports, your data travels encrypted with the payment and becomes unreadable after about 60 days. We never sell your data. City data comes from GeoNames (CC BY 4.0).

For reflection, not prediction

Astrology and numerology are offered for entertainment and personal reflection. They do not replace medical, psychological, legal or financial advice.
