Your data comes from your account. Another person can be used once or saved separately. Source data is fixed before interpretation.
Search uses OmenHall's local GeoNames cities500 copy, CC BY 4.0. No metered external geocoder is called for each search. GeoNames
Precise place coordinates (advanced)
Coordinates are needed for exact houses, angles, and synastry overlays. They are not fetched again for every calculation: OmenHall stores the resolved place in the Person Passport. The local GeoNames gazetteer supplies coordinates and IANA timezone without a paid API; manual entry remains a fallback for rare places.
Without a birth time, OmenHall must not show an exact Ascendant, MC, or houses. The result will be marked limited precision.
Without sign-in, data is not saved: you can use a one-time profile. After sign-in, Me and Saved Person become available.
