- Is a blurred face really anonymous?
- A strong pixelation or a solid box removes the information; a light blur does not, it can be partially reversed. Use strength 6 or more, or the solid box, when it matters. Also remember that clothing, surroundings and the file's metadata can identify people too.
- Why was a face missed?
- Very small, turned-away, heavily shadowed or partly covered faces can slip past the detector. That is why every region is editable: drag on the picture to add one. Always check the result before sharing.
- Does it work on licence plates or text?
- The detector only finds faces, but hand-drawn areas work on anything: plates, name tags, screens, documents. Draw a rectangle over it and pick the rectangle shape.
- Is the photo uploaded?
- No. Detection (YuNet, Apache 2.0, running via onnxruntime) and the rendering happen entirely in your browser. Nothing is sent anywhere.
- Does the download keep EXIF data such as GPS location?
- No. The image is re-encoded from pixels, so camera metadata including the location is not carried over.
