Baby Growth Tracker does not collect, store, or transmit any personal data to external servers. All data you enter — including your baby's name, date of birth, birth weight, birth length, and gender — is processed entirely within your browser and never leaves your device.
This app is designed to work fully offline. Once the page is loaded, no internet connection is required. There are no analytics, tracking pixels, or third-party scripts that monitor your usage. Your information stays on your device at all times.
We do not use cookies, local storage tracking, or any form of user identification. The app has no user accounts, no sign-up process, and no server-side component.

These libraries do not receive any of your personal data through this app.
The growth targets and ranges displayed in this app are not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider regarding your child's growth and development.
The growth standards and percentile ranges used in this app are derived from publicly available data on the internet, with the World Health Organization (WHO) Child Growth Standards being the primary reference. These standards represent statistical averages for healthy children and may not account for individual variations, genetics, or specific health conditions.
While we strive for accuracy, the target curves are generated through interpolation and mathematical modeling based on WHO monthly data points. Individual growth patterns vary significantly, and a child falling outside the displayed ranges is not necessarily unhealthy.
The app provides general reference targets, not clinical assessments. Factors such as prematurity, genetics, nutrition, and health conditions can all affect growth in ways that these generalized curves cannot capture.
The creators of Baby Growth Tracker accept no responsibility or liability for any decisions made based on the information provided by this app. Use of this app and its data is entirely at your own risk.
