That means passwords, tokens, personal notes, and documents you paste or load stay on your device. Clear the page or close the tab when you are finished on a shared computer.
You still need a network connection to load the page the first time. After that, the core processing for JSON Beautifier does not require sending your content to FileToolsHub.
