Places: Open-Meteo / GeoNames. No server birth-record database or analytics is used. Named charts and the latest working birth details are stored in browser localStorage; clearing browser data removes them.

Verification: all 120 values (7 planets, Total, Lagna and Rahu across 12 signs), and their row totals, match the supplied screenshot for its reference sign placements. This is a single-chart regression check, not proof that all settings of the unidentified original app match. The chosen Venus and Rahu rules are documented in the calculator.
