Who runs Photo Signals, and why it works this way

A privacy tool asks you to trust it. Here is what there is to check.

There is no server to trust
The site is static files on a CDN, and the code that reads your image runs on your device. It ships unbundled at /assets/engine/. Search it for fetch and you will find the word only in a comment saying there is none.
Why it says what it cannot do
Most tools in this space promise removal of things nobody can verify from outside. We report three classes instead. Someone may rely on this for their safety, and a false assurance is worse than a missing feature.
Who builds it
AIErudit, which runs a small group of browser-local tools sharing one rule: the file never leaves the tab. If something here is wrong, say so — and describe the file rather than attaching it.
