Privacy Policy

What this site is

Wernzi Tools is a free collection of online developer tools. All tools run entirely in your browser (client-side): the text, files and data you enter into a tool are processed locally on your own device and are not sent to our servers.

Information we collect

We do not require an account and we do not collect personal information directly. Your browser may store preferences locally (for example your favorite tools, theme and language) using local storage — this data stays on your device and is never transmitted to us.
