Only the information required to generate the requested response is transmitted.

We do not use your child's health information to train our own artificial intelligence or machine learning models.

AI-generated content may occasionally contain inaccuracies.

All AI-generated information is intended for educational and informational purposes only and should never replace professional medical advice.

Always consult a qualified healthcare professional for medical decisions.

5. AI-Powered Insights and Third-Party Processing

When you choose to enable AI Personalization (disabled by default), the app sends a limited set of your child's growth information to a third-party artificial intelligence service to generate personalized growth insights.

Who processes the data

AI requests are processed using Google's Gemini AI models through Firebase AI Logic, provided by Google LLC. Google processes this information solely to generate the requested AI response and return it to the app.

Google's handling of this information is governed by its own privacy policies:

Google is contractually required to protect this information to a standard consistent with this Privacy Policy. Firebase AI Logic operates under Google's Data Processing and Security Terms and, for applicable international transfers, Standard Contractual Clauses or equivalent legal safeguards (see Section 11) — providing the same or equivalent level of protection as described in this Privacy Policy.

Only the minimum information required to generate personalized insights is transmitted:

  • Child's age (in months)
  • Child's biological sex
  • Growth measurements:

    • Head circumference (when available)
  • Calculated growth metrics:

    • Growth trends
  • Selected growth standard (WHO, CDC, or IAP)

Information not shared

The following information is never sent for AI insight generation:

  • Child's name
  • Photos or uploaded images
  • Exact date of birth
  • Parent or caregiver name
  • Email address
  • Phone number
  • Home address

Your choice

AI Personalization is completely optional and is disabled by default.

Before any information is transmitted, the app presents an in-app disclosure explaining:

  • what information will be shared,
  • why it is needed,
  • which third party will process it, and
  • a link to this Privacy Policy.

AI requests are sent only after you explicitly consent.

You can disable AI Personalization at any time in Settings → Privacy Centre. Once disabled, the app immediately stops sending information for AI insight generation and removes any locally cached AI-generated insights.

Purpose of processing

The shared information is used only to generate personalized growth insights requested by you. We do not sell your information, use it for advertising, or share it with third parties for marketing purposes.

Processing, retention, and any additional handling performed by Google are governed by Google's applicable privacy policies and service terms linked above.
