Privacy

The short version: your photo never leaves your device, and we don't track you.

Your photo stays with you

Undertone runs entirely in your browser. When you choose a photo, it is read and analysed on your own device. It is never uploaded, never stored on a server, and never seen by us or anyone else. Close the tab and it is gone.

No accounts, no data collected

There is no sign-up and no login. We don't ask for your name, email, or anything else, because the tool doesn't need them and we have nowhere to put them.

One anonymous number, no tracking

Undertone keeps a single anonymous total on its own server: how many color reads have been completed, all-time. That is the whole of it. It sets no cookies, runs no advertising or third-party trackers, builds no profile of you, and cannot identify you or your device. Your photo is never part of it.

What does load from elsewhere

To work, your browser downloads a few standard files from public content networks: the web fonts (Google Fonts) and the on-device analysis models (Google and jsDelivr). Serving any file involves your browser's IP address by the nature of how the web works, and those providers have their own policies. We add no tracking on top of it, and none of these ever receive your photo.

Changes

If this ever changes, this page changes with it. As long as the tool works the way it does today, that won't be necessary.

Undertone is a personal project and a free tool. This page describes how it behaves, in plain language, rather than as legal boilerplate.
