How it works
ChartLumen resolves birth place, timezone, and chart facts first. AI receives structured JSON, not raw birth details alone.
Example output
Inter-chart aspects become communication prompts, not relationship instructions.
Safety note
Interpretations stay reflective and do not provide medical, legal, financial, crisis, or certainty-based future advice.
FAQ
Will it tell me to break up?
No. ChartLumen avoids coercive relationship advice.
Can names be hidden?
Yes. Public sharing defaults to aliases and hides exact birth data.
