Several timing methods in one workspace
AstroStarCheck begins with a saved person profile and a natal chart, then keeps short- and long-range timing methods in the same workspace. The visible tools include daily, weekly, monthly, and yearly views; transits; secondary progressions; solar returns; solar arcs; Firdaria major and subperiods; annual profections; relationship comparison; and historical-event backtesting. The chart area separates calculated facts, astrological rules, and conditional interpretation instead of presenting one aspect as a guaranteed event.
Relationship work has its own synastry section, while backtesting compares earlier life events with the active periods around them. The score system ranks relative activity inside the same person's timing baseline. It does not claim that a score is the probability of a specific event.
Chart calculations stay in the browser
Person profiles, birth details, historical events, and AI connection settings are stored in this browser until the user deletes them or clears site data. Natal charts, transits, progressions, solar arcs, Firdaria, synastry, and backtests are calculated in a browser worker with Swiss Ephemeris data. The site does not require an account for the local chart path.
Local-first does not mean every optional action is offline. Automatic place search sends the place name and interface language to a geocoding service. Requesting an AI reading sends the relevant question and chart context through the site's proxy to the provider selected by the user, and server-generated PDFs send report content for file creation. Analytics and advertising are controlled by the site's consent choices.
Eleven language routes and an optional AI layer
The official site links Simplified Chinese, Traditional Chinese, English, Japanese, German, French, Spanish, Russian, Portuguese, Italian, and Turkish versions. Public guides cover Firdaria, timing methods, synastry, uncertain birth times, backtesting, privacy, and interpretation limits.
Core chart calculations are presented as free. The AI layer is optional and depends on a provider configured by the user. Astrology is described as a symbolic interpretive tradition rather than a scientifically reliable way to predict specific events, so medical, legal, financial, and safety decisions still require real-world evidence and qualified advice.
