Privacy policy

Last updated 10 November 2026

The tools run entirely in your browser. What you type or paste (JSON, passwords, connection strings, expressions) is not sent to us. Some tools keep their inputs in the page address so you can share a link; the connection string builders and JSON tools don't.

We may use Cloudflare Web Analytics, which does not use cookies, to count page views. Cloudflare processes standard request data (such as IP address) to deliver and protect the site.

We also record anonymous usage counts for each page view so we can improve the pages: the page path (never what's in the address after it), the referring site or campaign tag, your country and device type, whether you used the tool, which buttons you pressed, how far you scrolled and how long the page was open. This uses no cookies and no identifiers that last beyond the page. Add ?notrack=1 to any page address to turn it off in your browser.

If we add advertising in future, this page will be updated before any advertising cookies are used.

Runs in your browser: nothing you paste is sent anywhere. Not affiliated with Microsoft, the .NET Foundation or the library authors.
