How ReColor Colorizes Photos On-Device on iPhone

TL;DR

ReColor's AI model runs entirely on your device, so photos are colorized without any upload, with no account required, and it works offline — your pictures never leave your phone.

Why it’s on-device

The colorization model runs on your iPhone, not a server.
Photos are never uploaded to be processed.
There’s no account and no sign-up.
It works offline, and results are auto-saved locally.

Why it works this way

Old family photos are about as personal as images get, and shipping them to a colorization server means handing your archive to someone else. ReColor keeps the AI on your device, so there’s no upload, no account, and nothing retained elsewhere — and no server round-trip means results appear in seconds. Private and fast are the same design choice.

Tips & edge cases

Airplane mode works — proof nothing is sent.
No sign-up means nothing tied to your photos.
Fast and local — on-device AI keeps it quick.
