Does Regex Tester upload my input?

No. DevQuickTools runs this testing tool in your browser. Static hosting receives normal page requests, but the values you type are processed locally.

Can I use Regex Tester for private work?

The tool is designed for local browser processing, but you should still avoid pasting secrets, passwords, private keys, or regulated personal data into any web page.
