Privacy policy

The short version: this site collects as little as possible, and the calculator runs entirely in your browser.

The calculator

The Sleep Regression Calculator runs completely in your browser. The birthdate you enter is used only to render your timeline on your screen — it is never transmitted to our servers, stored, or shared.

Analytics & cookies

This site currently sets no cookies of its own. If we add privacy-respecting analytics in future to understand which guides help most, this page will be updated first.

Embedded widget

The embeddable calculator behaves identically on third-party sites: it stores nothing and transmits nothing. Host pages may have their own privacy practices, which are outside our control.

External links

We link to medical sources (AAP, NHS, Cleveland Clinic and similar). Their sites operate under their own privacy policies.

Contact

A contact channel is being set up and will appear on the about page.
