Two-person synastry

Two charts, fully compared.

First calculate the complete facts: sky-relative score, every cross-aspect, both house overlays, composite chart and structural markers. This facts layer needs no sign-in and is not saved. The separate App interpretation turns it into direct answers; only then do we store the other person's minimal birth details.

Synastry compares two birth charts and may imply information about sexual orientation, so we ask for your explicit consent under GDPR Article 9. A calculation-only result is returned without saving the report or the other person's details. If you later save or unlock an interpretation, only a label and birth date, time and place are stored under your account; never a name, contact or photo. You may withdraw consent and erase stored synastry data at any time. Controller: Ying Yuet Fat, the individual operator of Anankeastro in Hong Kong.
