Made from two things that are a hundred years old.

The cards were drawn by Pamela Colman Smith in London in 1909. She hand-lettered every title and signed every card, and went uncredited for most of a century. The scans here are from a printing of that era, not from a modern reprint.

The sky comes from an ephemeris, the same arithmetic astronomers use. Every numbered card was assigned ten degrees of the zodiac by the Golden Dawn in 1888, so when the site says the Moon is on your card tonight, that is a fact you can check, and it prints when it stops being true.

The reading is written from the cards in their positions, and then you can reopen it from whatever caught your eye, because working from what the person noticed is how a reader works. Readings never predict dates, never give medical, legal or financial specifics, and never claim a track record.

How a draw is sealed

Before you touch the deck the order of the cards is fixed and a fingerprint of it is shown. After the turn, the seed is revealed under the card so the draw can be recomputed by anyone. Nobody, including the engine, sees the card before you do. Reversals are decided in the same shuffle, so the card was already that way up when you reached for it.

What is kept, and where

A reading you keep stays on your device. The draw, the reading and the sky are computed on the page. If you leave an address when you keep one, that reading is sent to you and filed under your address so it opens anywhere; nothing else ever leaves the page. What is stored, and where.

All seventy-eight cards are scans from a 1909 printing, in the public domain.
