# Progress photos that never leave your phone.

*Photos · https://undiet.app/features/photos*

People photograph themselves half dressed. Undiet handles that the way a banking app would: the photos are processed on the phone, stored on the phone, locked on the phone, and there is no button anywhere that sends one out.

## On this device, and nowhere else

The vault is a folder inside the app, not your camera roll. Nothing is uploaded to our servers, nothing is backed up by us, nothing is used to train anything. Not even we can see them. Delete the app and the photos go with it, which is exactly the point.

## Cut out on the phone

The pose guide fires the shutter when you are lined up, and the background is removed on the device. Whatever room you stood in, every photo lines up the same way, which is what makes comparing two dates honest.

## Ghost compare

Pick any two dates. The earlier photo fades over the later one, anchored on the same landmarks, and a slider moves between them. It is the quiet kind of progress, the one you notice by looking rather than by reading a number.

## Never posted, by design

There is no share button for photos, no before and after post, no option to enable one. The community is text only. The free app keeps the last 30 days of photos; Undiet Plus keeps the whole history.

## Keep the photos. Keep them yours.
