Privacy

The short version: what you type stays in your browser.

The calculator runs entirely on your device. Your bedtime, your drinks, and your answers are never sent to us, stored, or shared — there is no account to create and no database to leak. Close the tab and it's gone.

Like nearly every website, our hosting provider (Cloudflare) keeps standard server logs — things like request times and IP addresses — for security and uptime. We don't use them to identify you.

If this site ever shows ads or adds analytics, this page will say so plainly, including any cookies involved, before it happens. Today there are none.
