Privacy
Short version: the calculators run in your browser, we don't have accounts, and we don't sell anything about you.
What stays on your device
Some tools remember your last inputs (for example your last-period date, your baby's birth date and sex, measurements you've entered, name favourites and your wake-up time) so you don't have to retype them. These are stored in your browser's localStorage under keys starting with bb:. They never leave your device.

What is sent to a server
Only when you press the button in the baby name generator or ask a question in the sleep schedule helper is your text sent to our server, which passes it to an AI model through Vercel AI Gateway to produce the reply. We don't store these requests or link them to you. Please don't include full names, dates of birth or medical details you wouldn't want processed by a third-party AI service.
Analytics
We use Ahrefs Web Analytics, a cookieless analytics tool, to count page views and see which calculators are useful. It doesn't use cookies or build profiles of individual visitors.
