What we store

To calculate a chart we store the birth date, time and place you enter, the name or label you give the chart, the chart itself, and the readings we generate for it. We store the time zone your browser reports (a cookie named xpt_tz) so "today" is your today, and a cookie (xpt_guest) that remembers which charts you made on this device. If you buy a report, Stripe handles the payment; we receive the payment reference, the amount and the email you gave Stripe, never your card number.

What we do with it

Only what you see on the site: calculating charts, writing readings, generating reports, sending you the link you paid for. We do not sell or share personal data, and we do not use it to train models. Readings and reports are written by an AI model from the chart facts our engine computes; the model receives the chart facts and the label you chose, nothing else about you.

Who else sees it

Our hosting provider (the server the site runs on), Stripe (payments) and the AI provider that writes the readings (it receives chart facts, not your name or email). Place names come from GeoNames; positions from NASA JPL ephemerides. No advertising networks, no analytics that identify you.

How long

Charts and readings stay until you delete them (see Your data). Payment records are kept as long as accounting law requires.

Age

Stellunia is for adults. Do not use it if you are under 18. We do not knowingly keep data about anyone under 18; if you think we do, email us and we will delete it.
