What it looks for, and what it will miss

Findings below are covered already unless you untick them. To cover something it missed, turn on Draw a box and drag across it.

How it works: the picture is read in the page using the same text recognition that powers a scanner, then every word it finds is checked against the shapes that personal and secret information takes. A card number has to pass the checksum a real card passes. A social security number cannot start with the digits real ones never start with. A password only counts if what follows the label looks like an actual password rather than a placeholder. That is why the list below tends to be short and worth reading, instead of a hundred guesses. When you save, the covered areas are painted over the picture itself and the file is written fresh, so nothing survives underneath and no camera or location data comes along. Nothing is uploaded, and nothing here is sent anywhere.
