  • Wellness Context: Anonymized wellness metrics sent to Azure OpenAI to generate personalized nudges

How We Use Your Information

Important: Nalam does not operate any servers to collect or store your wellness data. We have no backend infrastructure, no cloud storage, and no database where your information could be stored.

Data Sharing

We do not sell, rent, or share your personal health data with third parties.

  • Azure OpenAI: If you provide your own API credentials, wellness context is sent to generate AI nudges. This is entirely optional and under your control.
