Real astronomy, written to keep

About The Moon Knows

We turn the real sky from the moment you were born into a beautiful, useful record of who you are, what is moving now, and the patterns you share with other people.

The product

A Book that begins on your birth night.

Your free first page uses real ephemeris calculations to show the sky you arrived under. Volume One: Origin goes deeper with nine personalized synthesis chapters, exact placement and aspect evidence, reflection margins, and a printable PDF.

The free astrology layer includes your Cosmic Identity Card, birth chart, compatibility, daily sky, and shareable artifacts. Moon+ adds the daily return: deeper personal transits, the full Year Ahead, and full-resolution keepsake downloads.

Your Book

A one-time personalized Origin volume, followed by a free natal Daily Page and lunar cycle.

Your relationships

Exact synastry between two charts, with a free overview and an optional full synthesis.

Your keepsakes

Live editors for star, chart, moon, map, and relationship artwork. Paid files are high-resolution PNGs; each editor lists its pixel dimensions and matching print guidance.

How it works

The calculation stays close to you.

Private by defaultBirth-chart math, reading assembly, and artwork rendering normally happen in your browser. Anonymous state stays on your device.

Accounts are optionalA magic-link account stores the minimum needed to recover purchases, Moon+ status, and Book state across devices.

Sharing is deliberateNothing becomes public unless you create a share or gift link. Those features tell you what will be saved before you submit.

Analytics require permissionEssential storage always works. Google Analytics and Meta Pixel load only after you choose Allow analytics. You can change that choice from the footer.

Payments and delivery

A purchase is verified before anything unlocks.

Dodo Payments is our merchant of record. It handles checkout, tax, and receipts. Reading and keepsake access is granted only after Dodo confirms payment. Purchase ownership can follow your email across devices, and a refund removes the related entitlement.
