How these tools treat your information
The tools are plain pages with a small script. What you type stays in your browser: it is not sent to Niva, not saved in cookies or storage, and not measured. Close the tab and it is gone.
A note on dates
Educational wellness support, not medical advice. Your care team confirms your dates and what fits your pregnancy.
