Why we built PanaKit
Many people looking for these answers are anxious, hopeful, or both. Too often they end up clicking between apps that want an account, pages buried in pop-ups, or charts that assume every cycle is 28 days. We wanted one calm, fast place that gives a sensible estimate, explains it simply, and is honest about its limits.
Who's behind it
PanaKit is built and maintained by Panabotics, an AI and software company based in Lahore, Pakistan. It also makes PanaPDF. PanaKit isn't run by a clinic or medical organization, and our content isn't reviewed by doctors. That's why we stick to published methods and show our sources.
How our calculators work
Each calculator uses a standard, published method. For example, due dates are counted from the first day of your last period, and ovulation is estimated by counting back from your next expected period. Where a method comes from clinical guidance, we link to it on the page. Sources include the American College of Obstetricians and Gynecologists (ACOG) and the UK's NHS. We test each tool against worked examples before publishing, and we explain its limits. Cycles vary, so every result is an estimate, not a certainty.
Your privacy
What you type into a PanaKit calculator is processed in your own browser. It isn't sent to us or saved anywhere. We use analytics to see which pages are useful, and we show ads to keep PanaKit free. You can manage cookies at any time with Cookie Settings in the footer. Read our Privacy Policy for the details.
How PanaKit is funded
PanaKit is free to use and supported by ads from Google. Advertisers have no say in our calculators or content. We don't sell products and don't use affiliate links.
Important: educational, not medical advice
PanaKit is for general information and education. It can't confirm a pregnancy, diagnose a condition or replace care from a doctor, midwife or fertility specialist. We work hard to be accurate, but we're human and mistakes can happen. Please check important dates and decisions with a healthcare professional. If something feels urgent, contact your doctor or local emergency services right away.
