What to include
- Reporting a bug or wrong result: the page address, the values you entered, the result you got and the result you expected. A screenshot helps.
- Suggesting a tool: what you want to do and where you looked first. Suggestions directly shape what we build next.
- Privacy questions: see our Privacy Policy first — it explains what is and isn’t collected.
Please don’t send personal financial documents or files you want processed. Our tools work in your browser precisely so that you never have to share them.
