How do I calculate my estimated due date (EDD)?

Enter your Last Menstrual Period (LMP) and we apply Naegele's rule (LMP + 280 days). If you know conception date, choose that (conception + 266 days).

Can I save vaccination reminders in my browser?

Yes — the Vaccination Reminder stores schedules in your browser's local storage and allows viewing/deleting saved schedules.

Is my data sent to the server?

No. These tools run client-side for privacy. Nothing is sent to the server unless you explicitly share it (e.g., newsletter signup).
