Privacy Policy

The dates you type into our calculators never leave your device. The calculations happen in your web browser, and there is no account to create and no form that sends your dates to us. We cannot see, store, or share information we never receive.

Calculator inputs: nothing. Your last-period, conception, scan and cycle dates are processed locally in your browser only.

Basic technical data. Like almost every website, our hosting provider (Cloudflare) processes standard request data — such as IP address, browser type and the pages visited — to deliver the site, keep it secure, and produce aggregate, anonymous statistics. This data is not used to identify you personally.

Email. If you contact us by email, we receive your email address and the contents of your message, and use them only to reply to you.

This site does not set advertising or tracking cookies of its own. When you click a product link to Amazon, Amazon's own cookies and privacy policy apply on their site — Amazon uses cookies to attribute purchases so that affiliate commissions can be paid. You can decline or delete cookies in your browser settings at any time; the calculators will still work.

Because we hold no personal data about calculator users, there is normally nothing for us to disclose or delete. If you have emailed us and would like that correspondence deleted, write to us at abdulazeem3255@gmail.com and we will delete it. Depending on where you live (for example under the UK GDPR or California law), you may have additional rights over personal data — we will honour any valid request.

If this policy changes, the new version will be posted on this page with an updated date at the top. Significant changes will be noted in the page content.
