About Pregnancy Calculator
Pregnancy Calculator was created with a single focused goal: to provide expectant parents, partners, and health-conscious individuals with fast, reliable, privacy-first pregnancy calculators and evidence-based educational resources.
Our Principles
1. Scientific Rigor
We use exact obstetric formulas from governing perinatology institutions (ACOG, CDC) and clearly disclose all calculation assumptions.
2. Privacy-First
We do not store your personal dates, menstrual cycles, or calculations on any server. Everything executes locally and safely in your browser.
3. Zero Gimmicks
No paywalls, no forced email registrations, and no dark UX patterns. You get instant access to the information you need.
