Privacy
Privacy policy
Short version: we don't collect personal data, don't use ad trackers, and don't sell anything.
What we collect
We collect nothing that identifies you. There's no signup, no email capture, no account system. The calculator runs entirely in your browser — the birthday or age you enter never leaves your device.
Analytics
If we run analytics, we use a privacy-friendly service (Plausible or Simple Analytics) that does not use cookies and does not collect personal information. You can browse the site with your preferred blockers without anything breaking.
Cookies
We use a single localStorage entry to remember your light/dark mode preference. That's it. You can clear it any time by clearing your browser's site data for this domain.
Third parties
The site loads a single web font (Cormorant Garamond + Inter) from Google Fonts. Fonts can be self-hosted in a future update to eliminate this dependency.
Children's privacy
This site is written for parents of babies. It is not directed at children under 13 and does not knowingly collect any data from children.
Changes
If we ever change how data is handled, we'll update this page. The policy last changed on 2025-09-01.
