The web tools process selected files locally and do not post photo bytes to the CleanMyGallery API. Browser extensions, the device, and downloaded files remain outside our control, so this is not a zero-risk security guarantee.
Before download
Selected image bytes are processed in your browser and are not posted to the CleanMyGallery API. When signed in, completion tracking sends the tool settings, counts, and byte totals needed for history and limits; original filenames and image bytes are excluded.
