What helps us fix things fast

• The tool's URL,
• what you entered and what you expected to see,
• your browser, if the tool misbehaved rather than miscalculated.

Because the tools run entirely in your browser, never email us the sensitive data itself — a description of the inputs is enough to reproduce any calculation.
