Reporting a calculation or content issue
Include the page name, the steps you followed, the result you expected and the result shown. For calculator issues, an invented example with the same behavior is enough; you do not need to include a real client’s details.
For an outdated source or factual correction, include a link to the relevant source and explain which statement needs attention.
Keep client information private
Please leave out client addresses, contact details, private business records, passwords and payment information when preparing feedback. JanitorMath’s tools can be used without sending us that information.
