ingimp automatically logs three types of information: command use, document characteristics, and interaction data.
ingimp records the names of commands used (e.g., "Paintbrush"), but not their parameters. For example, ingimp records when you use the text tool, but not the text you use. Similarly, it records that you use the Paintbrush, but not the colors used nor where you paint. It also records the names of scripts, so if you have custom scripts you have created, their names will be recorded for anyone to see.
Commands provide a picture of what you are doing, but don't tell us anything about the nature of documents on which you are working. Thus, ingimp logs general descriptions of the documents edited: Their size, number of layers, image histograms, and so on. These data give an indication of whether people generally work on large or small images, complex or simple images, and photographic images or graphic illustrations.
Finally, ingimp logs interaction data, or information regarding how you use the application in general. ingimp records keyboard and mouse activity, but not the actual keys or mouse location. That's worth repeating: ingimp does not record what keys are pressed nor where clicks, drags, or pointer movements happen when using a pointing device like a mouse or stylus. ingimp also records the sizes and locations of windows, when they gain "focus" (i.e., when they are in the front), the platform you use it on (e.g., Windows or Linux), the size(s) of your monitor(s), among other data.
