1. Introduction

NestMate ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclosure, and safeguard your information when you use our mobile application and website (collectively, the "Service").

By using NestMate, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect

2.1 Personal Data

We may collect personally identifiable information, such as:

  • Email address (for account creation and authentication)
  • Baby's name and birthdate (for growth tracking and age-appropriate insights)

  • Sleep sessions
  • Diaper changes
  • Growth measurements (height, weight, head circumference)

2.3 Voice Data

When you use our AI Voice features ("NestMate, log a wet diaper"), audio is processed to convert speech to text. We leverage on-device processing where possible. If cloud processing is required for specific intents, transient audio data is encrypted and discarded immediately after transcription.

3. How We Use Your Information

We use your data to:

  • Provide, operate, and maintain the Service.
  • Calculate growth percentiles based on WHO/CDC standards.
  • Generate personalized insights (e.g., "Your baby sleeps best after a 6 PM feed").
  • Authenticate users and manage shared family access.

4. Data Storage and Security

We use Google Firebase (a Google Cloud Platform service) to securely store your data. Your data is encrypted in transit and at rest.

While we strive to use commercially acceptable means to protect your Personal Data, remember that no method of transmission over the internet or method of electronic storage is 100% secure.

5. Third-Party Services

We may employ third-party companies and services to facilitate our Service:

  • Google Analytics: To analyze Service usage.
  • Google Firebase: For backend services, authentication, and database hosting.
  • OpenAI / Vertex AI: For generating natural language summaries and blogs.

These third parties have access to portions of your Personal Data only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.

6. Your Rights

You have the right to:

  • Access the personal data we hold about you.
  • Request correction of inaccurate data.
  • Request deletion of your account and all associated data ("Right to be Forgotten").
  • Export your data in a machine-readable format.

While our Service is designed to track information about children, it is intended to be used by parents and guardians. We do not knowingly collect personal identifiable information directly from children under 13. If you become aware that a child has provided us with Personal Data, please contact us.

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
