Privacy
What these pages do with your data: nothing that leaves your browser.
Your input stays on your device. Every tool on this site computes in your browser. What you type into a tool is never sent to this site or to anyone else; there is no form submission, no upload and no account.
Nothing is stored about you. The site keeps no log of who used which tool. The only thing written to your device is a copy of the tool's own files, so that it keeps working when you have no connection; your browser lets you clear it like any other site data.
No analytics and no advertising run on these pages today. If an advertising slot or a traffic measure is ever added, this page will name the provider, what it receives, and the consent it asks for first — before anything is switched on.
Links out. The explanatory text links to public standards documents. Following a link takes you to that site, under its own policy.
