The short version
👍 All our calculators run in your browser. Your inputs (due dates, names you're checking, baby weights, etc.) are NEVER sent to our server.
👍 We do not require an account, login, or any personal information to use the tools.
👍 We use minimal analytics to know which tools are popular. No personally identifying data.
👍 We do not sell any data. Ever.
1. Who is the data controller
prenatalcalculator.com ("we", "us") is the data controller for the personal data we process on the Canada edition. You can contact us at hello@prenatalcalculator.com.
2. What data we collect
2a. Information you provide directly
If you choose to contact us by email or fill in a contact form, we receive:
- Your name (if you provide one)
- Your email address
- The message you write to us
2b. Information collected automatically
Like most websites, our hosting provider logs:
- Your IP address (anonymised after 30 days)
- Browser type and version
- Device type (mobile, desktop)
- Pages visited and time spent
- Referring website (which site sent you here)
This information is collected for security (to detect abuse) and analytics (to understand which tools are useful).
2c. Information you input into calculators
Critically: the data you type into our calculators (due dates, baby weights, names you're considering, salary figures, etc.) stays in your browser. We do not transmit this to our server. We do not save it. We do not see it.
3. What we do NOT collect
- We do not require you to create an account
- We do not ask for your phone number for tool access
- We do not ask for your full name, address, or government ID
- We do not store your medical history, pregnancy details, or family information
4. Cookies
We use minimal cookies:

- Analytics: we may use privacy-respecting analytics (no third-party tracking pixels by default)
You can disable cookies in your browser settings. Most tools will continue to work without cookies.
5. Third parties
Our website is hosted by Hostinger, who processes web server logs as a data processor on our behalf. We do not sell, rent, or share your data with marketing companies, data brokers, or advertisers.
