Privacy policy: Due Date Calculator
Last updated 2026-10-21
What this tool does with your dates
- The dates you type are about your health, so they stay with you: they are used by code running in your browser on your own device, are never sent to us or anyone else, and are not stored.
- There is no account and no cookie. We count visits with a code that changes every day and cannot identify you, plus the site that linked you here and your device type, and how many times a result is read: only which starting point was chosen (last period, conception, IVF, ultrasound or due date), never a date.
This page covers Due Date Calculator only. The site-wide Privacy Policy covers everything else, and the Terms of Use apply to every tool.
