What to include in your message
How we can help
Write to us about calculator errors, content corrections, source updates, accessibility problems, privacy requests, or relevant partnerships. For a calculator problem, include enough detail for us to reproduce it.
Calculator or content correction
Include the page URL, sample inputs, the result received, and the expected result. Use a made-up birth date whenever it can demonstrate the same issue.
Accessibility or source question
For accessibility, include the browser, device, assistive technology, and difficult step. For a data update, link to the authoritative provider or dataset.
Privacy or general support
Identify the page or email involved without repeating sensitive information. Privacy requests may require reasonable verification before contact records are changed or deleted.
Partnerships
Relevant, transparent proposals are welcome. We do not sell followed links, publish guest posts solely for SEO, arrange fake reviews, or guarantee promotion or search visibility.
