We read every message. Whether you've found a bug, spotted an error in an article, or have a privacy question, here's how to reach us.
General questions and feedback
Ideas for new features, questions about how the estimator works, or just want to tell us your result? Send us an email. Feedback has shaped almost every change we've made.
Corrections
If you believe an article contains a factual mistake or out-of-date information, please include the page link and, if possible, a source. We review every correction request and update pages where needed.
Privacy and data requests
Our calculator doesn't store your answers, so we usually hold no personal data about you. If you have questions about cookies, advertising, or wish to exercise rights under GDPR or CCPA, write to us with "Privacy request" in the subject line and we'll respond within 30 days.
Advertising and partnerships
We don't accept paid articles or sponsored reviews. For other business enquiries, email us with a short description of your proposal.
Please don't send medical questions — we're not able to give personal health advice. Contact a qualified healthcare provider instead.
