Privacy

The photos people colourise are family history — irreplaceable and personal. This tool is built so those images never have to leave your device to gain colour.

How a photo flows through it: you pick or drop an image; a real colourisation model (DDColor) runs inside the tab via WebAssembly; the predicted colour is recombined with your photo's own brightness; and you download the result. There is no server in that path — the site is static files plus a model the browser fetches once, so a photo has nowhere to be sent.

What survives the session: nothing at all. The image sits in this tab's memory while you work and is dropped the instant the tab closes — never written to a server, never logged.

The offline proof: after the model has cached on first use, turn off your network and colourise — it still works completely. That is the whole privacy claim, and you can check it in one step.

The model download comes from a static file host on first run and is then cached; it carries no data about you either way.

Measurement: a bare visit count from the host, nothing more. No analytics library, no advertising pixel, no login, no cookie planted to recognise you, and not even a web font request — the type is whatever your system already has.
