Privacy
Your images are never uploaded, because there is no server here to upload them to.
What happens to a file you open
It is read into this browser tab and processed by code running on your device. It is not sent anywhere, not stored, and not retained — there is no upload endpoint in this site's code, and you can read that code: it ships unbundled, at /assets/engine/.
What we collect
Two anonymous counts, and they are named here because you should be able to check them against the shipped source: work_started and work_completed. That is the whole list — the code refuses any other name before it sends. Two anonymous counts: that a piece of work started, and that it finished. No file name, no format, no size, no findings, no result. A count of what your file contained would be a fact about your file, and this site does not learn facts about your file.
The analytics are cookieless, carry no identifier for you, and are not collected at all if your browser sends a Do Not Track signal.
What we do not have
No accounts, no sign-in, no email list, no advertising, no third-party scripts, no payment. Nothing to breach and nothing to hand over.
