json-validator.org is designed to be private by default. All functionality of the JSON tools (viewer, formatter, diff, conversions) runs entirely in your browser. Your data is not uploaded to any server and is not stored remotely by these tools.
The core tools do not rely on cookies. If lightweight analytics are used, they are only to understand aggregate usage and improve the site. Such analytics, if present, do not include your JSON content.
This Chrome extension does not request access to any websites or user data. It only runs on JSON documents that your browser is already displaying and processes them locally to improve readability.
No additional permissions (such as tabs, activeTab, or broad host permissions) are required. The extension simply formats and highlights JSON responses directly in your browser. It does not collect, transmit, or store any of your data.
