About Dozofy

The Dozofy Team

Dozofy is built by a small team that got tired of sleep websites cluttered with pop-ups, endless ads and accounts you never asked for. We wanted something simpler: type a time, get a clear answer, and get on with your evening.

Why we built this

We're genuinely interested in sleep science — how cycles work, why waking up at the wrong moment leaves you groggy even after a full night, why a consistent schedule matters more than most people realize. Most of the sleep calculators we found online were slow, ad-heavy, or available only in English. So we built our own: fast, free, and translated into seven languages (English, French, Spanish, German, Russian, Arabic and Chinese), with a dark, calm interface that doesn't fight you at 11pm.

How we handle your data

Dozofy doesn't require an account. There's nothing to sign up for and nothing to log into. Where we offer a feature that needs to remember something — like your sleep diary entries — that data is stored locally in your own browser (via localStorage), on your device. It is never sent to our servers. If you clear your browser data or switch devices, that local history goes with it; we don't keep a copy.

What we are (and aren't)

We're not doctors, and nothing on Dozofy is medical advice — our calculators and guides are built from widely accepted, publicly available sleep science, meant to help you plan better nights, not to diagnose or treat anything. If something about your sleep feels seriously off, please talk to a real clinician.

Keep in touch

Dozofy is a work in progress, and we keep adding tools based on what people actually search for and ask about. If you have feedback or found something broken, we'd like to hear about it.
