Your input never leaves your browser

Every tool on this site — the pattern extractor, the dedupe and sort tools, the case converter, and the JSON formatter — runs entirely as JavaScript inside your browser tab. The site itself is a collection of static files served from a CDN. There is no backend API that receives anything you paste or upload.

You can verify this by opening your browser's developer tools, switching to the Network tab, and using any tool. You will see no request that includes your input data.

What is collected

The site uses Google Analytics to count page views and understand which tools are used most, so we know where to invest. Google Analytics collects standard anonymous metrics — referrer, page path, country, device class — but never the contents of what you paste into a tool.

We use file-loading and clipboard APIs in your browser; these are local-only browser permissions and do not transmit data to us.

Cookies

Google Analytics sets its own cookies. The site itself stores a small handful of preferences (theme, "remove duplicates" toggle) in your browser's localStorage. None of that is transmitted anywhere.

Advertising

If we display third-party ads on this site, those ad networks may set their own cookies and collect device-level information per their own privacy policies. They never receive what you paste into our tools.
