MiniLog – Feed Tracker - Privacy Policy

Last Updated: November 21, 2025 Effective Date: September 3, 2025

Overview

MiniLog is designed with privacy as a core principle. We believe your baby's feeding data is sensitive health information that should remain under your complete control.

Data Collection and Storage

What Data We Collect

MiniLog collects only the information you explicitly enter:

Feeding Data:

  • Date and Time - When the feeding occurred
  • Volume - Amount of milk/formula consumed (in mL)
  • Formula Type - Type of milk or formula used
  • Waste Amount - Amount of milk wasted (when advanced features enabled)

Pumping Data:

  • Date and Time - When the pumping session occurred
  • Volume - Amount of milk pumped (in mL)

Where Your Data is Stored

Google Sheets Storage:
  • All feeding and pumping data is stored directly in Google Sheets within your own Google account
  • MiniLog acts only as a client to write data to your spreadsheets
  • We have no access to your Google account or spreadsheet data
  • Your data never passes through our servers

Local Device Storage:

  • App settings (daily volume goals, formula types, spreadsheet ID)
  • Google OAuth tokens (managed by Google's SDK)
  • Last used formula type (for Siri convenience)
  • Haptic feedback preferences
  • Quick volume button configurations
  • Advanced features toggle state

Data We Do NOT Collect

  • Personal identifying information
  • Contact information (email, phone, address)
  • Location data
  • Device identifiers
  • Usage analytics or crash reports
  • Any data outside of what you explicitly enter

How We Use Google User Data

MiniLog's use of information received from Google APIs will adhere to Google API Services User Data Policy, including the Limited Use requirements.

Specific Uses of Google User Data

Google Sign-In (Authentication):

  • Data Accessed: Your email address and basic profile information
  • Purpose: To authenticate you and identify your Google account
  • Usage: Email is displayed in Settings to show which account is connected; not stored on our servers or shared with third parties
  • Storage: Authentication tokens are stored securely on your device by Google's official SDK

Google Sheets API:

  • Data Accessed: Contents of spreadsheets you explicitly select or create with our app
  • Purpose: To read existing feeding data and write new feeding/pumping entries
  • Usage: Data flows directly between your device and Google's servers; we never store or access your spreadsheet data on our servers
  • Storage: Spreadsheet data remains in your Google account; we only store the spreadsheet ID locally on your device for quick access

Google Drive API (drive.file scope):

  • Data Accessed: Files created by MiniLog in your Google Drive
  • Purpose: To create new tracking spreadsheets with proper column headers
  • Usage: Limited to creating and accessing only files that MiniLog creates; cannot access other files in your Drive
  • Storage: Files are stored in your Google Drive; we have no server-side storage

Google Drive API (drive.readonly scope - optional):

  • Data Accessed: List of spreadsheets in your Google Drive (filename and modification date only)
  • Purpose: To help you find and connect to existing tracking spreadsheets shared by other users (e.g., shared between two parents)
  • Usage: Read-only access for browsing only; filtered to show spreadsheets with "tracker" in the name; you must explicitly select which spreadsheet to connect
  • Storage: Spreadsheet list is not stored; only the ID of your selected spreadsheet is saved locally on your device

Data Use Limitations

We use Google user data ONLY for the following purposes: 1. Authenticating you to access Google Sheets 2. Writing feeding and pumping data you enter to your selected Google Sheet 3. Reading your existing feeding data to display totals and analytics 4. Creating new tracking spreadsheets in your Google Drive when requested 5. Browsing your spreadsheets to help you connect to shared tracking sheets

We do NOT use Google user data for:

  • Advertising or marketing purposes
  • Training machine learning models
  • Sharing with third parties (except as required to provide the service via Google's APIs)
  • Any purpose not directly related to the core feeding tracking functionality

Third-Party Services

Google Services

MiniLog integrates with Google services for core functionality. All Google services are governed by Google's Privacy Policy and Google Cloud Privacy.
