Everything stays on your phone.
Your birthday, your reflections, your photographs, your milestones — all of it lives on your device and nowhere else. The app has no accounts, no analytics, no advertising, and no servers. It never connects to the internet: the moon is computed, not fetched.
If you share something from the app — a poster, a picture of your moons — it goes only where you send it, and only when you choose to.
This website is the same. The "how many moons have you lived" calculator runs entirely in your browser; your birthday is never transmitted, stored, or seen by anyone. Arrive here on your own — typed, bookmarked, sent by a friend — and the site sets no cookies and uses no trackers.
Arrive from one of our ads, and the site loads Meta's measurement pixel so we can tell which ad worked. It learns three things and nothing more: that the page was seen, that a download badge was tapped, and whether an unlock was bought. Never your birthday, never your moons.
If you unlock your full calendar, payment happens on Stripe’s own secure checkout page — your card details never touch this site, and your birthday is never sent to Stripe. Afterwards your unlock lives in your browser; to restore it on another device we check the email from your receipt against the purchase record, and nothing more. Refund questions: write to the address below.
