What you can do

Use the tools freely — for any project, commercial or personal, no attribution required.
Share the URL fragment links the tools generate.
Embed or screenshot the rendered output for your own work.
Read, fork, and contribute to the source on GitHub.

What you can't do

Mass-scrape the site or hit the rate-limited endpoints in a loop.
Repackage the tools as a paid product without giving notice and credit.
Upload illegal content, malware, or anything that violates a third party's rights.

No warranty

The tools are provided as-is. They run in your browser, so they depend on your browser working correctly. I make a reasonable effort to keep them stable but I don't promise uptime, backwards-compatible URLs, or persistence of any data you put into them. Don't use them as the sole storage for anything irreplaceable.

Privacy and data

The site has no backend that sees your code, no account system, and no tracking cookies. Read the privacy policy for the specifics on what stays on your device.
