The short version
Everything you type into our calculators — period dates, due dates, birth dates, measurements — is processed in your own browser. It is never sent to us, stored or shared.
Information we collect
- Calculator inputs: none. Calculations happen on your device.
- Server logs: our hosting provider, Cloudflare, processes standard technical data such as IP address, browser type and pages requested to deliver and secure the site. See Cloudflare’s privacy policy.
- Emails you send us: if you contact us, we keep your message only as long as needed to reply.
Cookies and analytics
We do not currently use advertising cookies or tracking cookies. If we add privacy-friendly analytics or advertising in the future, we will update this page and, where required, ask for your consent first.
Children’s privacy
CalcMyBaby is intended for adults. We do not knowingly collect personal information from children.
Your rights
Because we don’t store personal data from our calculators, there is usually nothing to access or delete. For any privacy question, email [email protected].
