What to Expect
Calculator errors are treated as the highest priority. If you report a formula that looks wrong, include the calculator name, the values you entered, and the result you expected. I investigate every report and fix confirmed errors within 1 to 2 business days.
General questions are answered within 2 to 3 business days. If you’re a finance professional, healthcare provider, or engineer and something looks technically wrong — I especially want to hear from you.
Tool suggestions are added to the development list. If a calculator you need doesn’t exist on the site, send a request and I’ll consider it for a future release. I’ll follow up when it goes live.
Advertising enquiries are managed through Google AdSense. I do not handle ad placements, sponsorships, or paid partnerships directly.
