Time and place are used for the Ascendant and whole-sign houses.

No sign up required. Raw birth inputs are not persisted for session-only charts; a redacted, authorized server record of derived chart facts and this browser session keep the workspace functioning.

How it works

ChartLumen resolves birth place, timezone, and chart facts first. Optional generated wording receives a minimized allowlist of derived chart facts, not raw birth inputs.

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.
