This policy explains what information DueNest collects, how it is used and the choices you have.
Last updated: October 2, 2026
DueNest (https://duenest.site) is operated by [OWNER OR COMPANY NAME], [ADDRESS, COUNTRY]. For privacy questions, contact us at [CONTACT EMAIL].
Our calculators run entirely in your web browser. Dates, cycle lengths, measurements and other details you type into a calculator are not sent to our servers and are not stored by us. When you close or reload the page, they are gone.
If you use our contact form or email us, we receive your name, email address and message. We use this only to reply to you and keep it for up to [12] months, unless we need it longer to deal with a complaint or a legal obligation.
If you sign up for our newsletter, we store your email address, your language and, if you give it, your due date on our website server. We use them only to send the newsletter, and we may use an email service provider to send it. You can unsubscribe at any time using the link in every email, and we delete your details on request.
Like most websites, our hosting provider records basic technical data such as IP address, browser type and pages visited, to keep the site secure and working. We may use analytics tools, such as Google Analytics, to understand how visitors use the site. These tools use cookies; see our Cookie Policy.
We may show ads provided by third parties such as Google AdSense. These partners may use cookies to show ads based on your visits to this and other websites. Where the law requires it, we ask for your consent first. You can manage personalised ads in your Google ad settings.
We do not sell your personal information. We share it only with service providers who help us run the site (for example hosting, email and analytics), and only as needed for them to provide their service, or when the law requires it.
Depending on where you live, including under the GDPR in the UK and EU and privacy laws in US states such as California, you may have the right to access, correct or delete your personal information, to object to or restrict how we use it, and to withdraw consent. To make a request, email [CONTACT EMAIL]. You can also complain to your local data protection authority.
This site is intended for adults. We do not knowingly collect personal information from children under 13 (or under 16 where local law requires).
We may update this policy from time to time. The date at the top of the page shows when it last changed.
