Privacy

The short version: your birth data never leaves your device. Charts are computed locally in your browser. We don't run accounts, we don't ask for your name, and we don't sell anything to anyone.

What stays on your device

Birth date, time, timezone, and the computed chart. If you share your chart, the birth data travels inside the link's #fragment — fragments are never sent to web servers by browsers, so it goes only to the person you choose.

What we do collect

• Anonymous usage counts — page views, chart computations (type/profile only), purchases. These contain no birth data and no identifiers.
• Email, if you type it — for the chart-summary email or the Gene Keys launch list, stored only to send what you asked for.
• Checkout email — processed by Stripe under their privacy policy; we keep only what's needed to restore your purchase.

Cookies & local storage

We set one local entry remembering how you found us (a ref or campaign code, for 30 days) and, if you purchase, one unlock token on your device. No advertising cookies, no third-party trackers beyond optional analytics we may enable with the same anonymous events.
