Contact
Questions, bug reports, and tool suggestions are all welcome. We read everything and reply to most messages within a few days.
What to Include
- Bug reports — which tool, what you did, what happened, and what you expected. Your browser and device help a lot.
- Tool suggestions — describe the problem rather than the solution. What were you trying to do when you needed it?
- Corrections — if a tool gives a wrong result, tell us the inputs so we can reproduce it.
What We Cannot Help With
We cannot provide medical, legal, financial, or engineering advice, and we cannot recover data — the tools never receive your data in the first place, so there is nothing on our side to retrieve.
Privacy
Emails you send are used only to answer you. See our Privacy Policy for details.
