How to send a useful report

If possible, include the page URL, what you entered, what the tool returned, what you expected, and the browser or device used. For calculations, sharing dates, values, and assumptions usually speeds up analysis a lot.

Response time

We aim to reply within 2 business days. Commercial requests and critical corrections may be prioritized, especially when they affect interpretation, user trust, or important workflows.
