Your date of birth is never sent to us. The calculator runs entirely in your browser. We do not receive it, store it, or log it.
What is stored on your device
One small setting: whether you chose the Playful or Cosmic look, kept in your browser's local storage so the site remembers next time. Nothing else. You can clear it any time by clearing your browser data.
Shared links
If you copy your link to send to someone, the birthday is written into that link so their page opens on your result. That link exists only where you paste it.
Email reminders
Milestone reminders are not switched on yet. Nothing is collected, and the form on the page says so. When they are enabled, this page will state exactly what is stored, who processes it, and how to unsubscribe — before any address is accepted.
Analytics and advertising
This section will be completed before launch, naming any analytics or advertising provider used and what each one sets. If you are reading this on a live site and it still says this, neither is in place yet.
