Privacy Policy

Last updated: May 2026

We respect your privacy. The following text describes our policies for collecting and handling data. If you have any questions, please contact us.

Throughout this policy, "the website" refers to the Global Child Health Database (also known as the Maventy Child Health Database), available at childhealth.maventy.org. "The app" refers to the Maventy Mobile app, available on Google Play. "We," "us," and "our" refer to Maventy, the operator of both.

Medical Disclaimer

The website and app are informational tools, not medical devices. They do not diagnose, treat, or prevent any medical condition. Growth scores and nutritional assessments provided are for reference purposes only. Always consult a qualified healthcare provider for medical advice.

Health and Personal Data We Collect

The core purpose of the website and app is to calculate WHO-standardized growth z-scores and nutritional status reports for children. To do this, we collect the following data about the children whose records are entered:

• Date of birth and sex
• Visit date
• Weight and height or length (and whether the child was measured standing or recumbent)
• Optionally: head circumference, arm circumference, triceps skinfold, and subscapular skinfold measurements

We also collect account information for registered users of the website, including name and email address.

We collect this information only as necessary to fulfill the purpose of calculating and storing growth assessments. We do not sell or share any health data or personal information with third parties for advertising or any other purpose.

How We Use Health Data

Child health measurements are used solely to calculate WHO-standardized growth z-scores and percentiles (weight-for-age, length/height-for-age, weight-for-length/height, BMI-for-age, and optional indicators such as head circumference, arm circumference, and skinfold measurements) and to store those results for the authorized users of the relevant account.

Data Retention

We retain data indefinitely unless you request deletion. If you would like your data or your patients' data deleted, please contact us and we will remove it.

Data Subject Rights

Regardless of your location, you have the right to access, correct, or request deletion of data we hold about you or your patients. To exercise any of these rights, please contact us.

Website Visitors

Like most website operators, the website collects non-personally-identifying information of the sort that web browsers and servers typically make available, such as the browser type, language preference, referring site, and the date and time of each visitor request. Our purpose in collecting non-personally-identifying information is to better understand how visitors use the website. From time to time, we may release non-personally-identifying information in the aggregate, e.g., by publishing a report on trends in website usage.

The website also collects potentially personally-identifying information like Internet Protocol (IP) addresses. We do not use such information to identify visitors, and do not disclose it other than under the same circumstances described in the section below.

Aggregated Statistics

We may collect statistics about the behavior of visitors to the website. We may display this information publicly or provide it to others. We do not disclose personally-identifying information other than as described below.

Protection of Personally-Identifying Information

We disclose potentially personally-identifying and personally-identifying information only to those employees, contractors, and affiliated organizations that (i) need to know that information in order to process it on our behalf or to provide services available at the website or app, and (ii) have agreed not to disclose it to others. Some of those employees, contractors, and affiliated organizations may be located outside of your home country; by using the website or app, you consent to the transfer of such information to them. We will not rent or sell potentially personally-identifying and personally-identifying information to anyone. Other than to our employees, contractors, and affiliated organizations as described above, we disclose personally-identifying information only when required to do so by law, or when we believe in good faith that disclosure is reasonably necessary to protect the property or rights of Maventy, third parties, or the public at large.

If you are a registered user and have supplied your email address, we may occasionally send you an email to tell you about new features, solicit your feedback, or keep you up to date. If you send us a request (for example via a support email or via one of our feedback mechanisms), we reserve the right to publish it in order to help us clarify or respond to your request or to help us support other users. We take all measures reasonably necessary to protect against unauthorized access, use, alteration, or destruction of personally-identifying information.

Cookies

A cookie is a string of information that a website stores on a visitor's computer, and that the visitor's browser provides to the website each time the visitor returns. The website uses cookies to help identify and track visitors, their usage of the website, and their access preferences. Visitors who do not wish to have cookies placed on their computers should set their browsers to refuse cookies before using the website, with the drawback that certain features may not function properly without cookies.

Privacy Policy Changes

Although most changes are likely to be minor, we may change this Privacy Policy from time to time, at our sole discretion. We encourage you to frequently check this page for any changes. Your continued use of the website or app after any change in this Privacy Policy will constitute your acceptance of such change.
