Calculator for Sleep is being built. This page covers how the preview handles your data and how to reach us.
The sleep calculator runs entirely in your browser. The times you enter are never sent to a server and are not stored anywhere.
If you choose to leave your email for a launch notification, we store that single email address so we can send you one message when the full site goes live. We do not run a newsletter, and we never sell or share your address.
We use privacy-friendly, cookieless analytics to count visits and understand which pages are useful. Optional Google Analytics loads only after you interact, and in regions that require consent it loads only if you accept. You can decline without losing any feature.
Have a question or a correction? Send a message below and it reaches us directly. You do not need to share your email unless you want a reply.
