How these tools handle your data
Each tool page carries a processing label. “Runs in your browser” means the work happens locally with JavaScript. “Public lookup” tools send only the value you type — such as a hostname or MAC address — to a documented third-party API. “Uses a KitJade API” means a small Cloudflare Worker performs the check so that browser CORS rules cannot be bypassed.
