What to get in touch about

Reporting a bug effectively

Because every tool runs client-side, results can occasionally differ between browsers. If you hit something odd, mentioning your browser and version alongside the input that triggered it usually makes the problem reproducible on the first try.

Please do not email sensitive data. If a bug involves confidential input, reduce it to a small non-sensitive example that still reproduces the problem. The tools never transmit your data — email very much does.
