Contact

ImageDup is a small, focused tool. Get in touch about any of these:

A bug, or a CSV that the tool handles incorrectly.
A question about how the URL and hash matching works.
A privacy question about how the site handles data.

Before reporting a matching problem, it may help to read what counts as a duplicate — some results that look wrong are the conservative matching rules working as intended.

For what happens to your data, see the Privacy Policy.
