An independent compilation
Facts like a date and a place aren’t owned by anyone, but copying another site’s database is a different matter. So we compile independently from ordinary public sources: encyclopedias, biographies, interviews, official registries where they’re public. We deliberately do not use astrology databases as a reference, so the independence of this base can be verified.
Dates and places come from public reference data. Birth times, the hard part, are curated by hand, each with a documented source, and never invented.
