Frequently Asked Questions
Include the calculator name or page URL, expected behavior, actual behavior, and steps to reproduce. Sample inputs and a description of what you saw help us prioritize and fix issues faster — the form takes text, so describe a screenshot rather than attaching one.
No account is required — you can submit feedback as a guest. The form does ask for an email address, so we can follow up when more details are needed.
