About Period Calculator
Empowering women with privacy-first health tools
Our Mission
We believe every woman deserves access to accurate, private menstrual health tools. Our mission is to provide a reliable period calculator that respects your privacy while helping you understand your body better.
Why We Built This
Many existing period tracking apps require you to create an account, share personal data with third parties, or worry about data breaches. We wanted to create something different.
- Privacy First - All your data stays on your device. We never see or store your personal information.
- No Account Required - Start using immediately without registration or login.
- Accurate Predictions - Our algorithms are based on established medical research.
- Completely Free - No premium features, no subscriptions, no hidden costs.
Our Approach
We are committed to providing accurate, evidence-based information. All our content is:
- Reviewed by professionals - Our content is reviewed by qualified healthcare professionals.
- Based on authoritative sources - We reference ACOG, NHS, WHO, and other authoritative medical organizations.
- Regularly updated - We review and update our content quarterly to ensure accuracy.
