Last Updated: November 2025

1. Introduction

NutriAgent Bot ("we," "us," or "our") is a personal project operated by an individual developer (the "Operator"). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Telegram bot service (the "Service").

By using NutriAgent Bot, you consent to the data practices described in this Privacy Policy. Please read this policy carefully to understand our practices regarding your personal information.

2. Information We Collect

2.1 Information You Provide

When you use NutriAgent Bot, we collect the following types of information:

  • Telegram Messages: Text messages you send to the bot describing your meals, snacks, or nutrition-related questions
  • Images: Photos of meals you send to the bot for image recognition and nutritional analysis
  • Telegram User Information: Your Telegram user ID, username (if available), and basic profile information necessary to identify your account
  • Google Account Information: When you connect your Google account via OAuth, we receive:
    • Your Google account email address
    • Basic profile information (name, if available)
    • Access tokens to create and manage Google Sheets in your Google Drive

We may automatically collect certain information when you use the Service:

  • Usage data and interaction logs (e.g., timestamps, message types)
  • Technical information about your device and Telegram client
  • Error logs and diagnostic information for troubleshooting

2.3 Information Stored in Google Sheets

All nutrition data derived from your messages and images is stored in Google Sheets that we create in your Google Drive. This data includes:

  • Meal descriptions
  • Estimated nutritional information (calories, macronutrients, etc.)
  • Timestamps of meals
  • Any additional information you provide through conversation

Important: This data is stored in your own Google Sheets that you own and control. We access this data only to write new entries when you interact with the bot.

3. How We Use Your Information

We use the information we collect for the following purposes:

3.1 Service Provision

  • To process your messages and images and provide nutritional information
  • To create and update your Google Sheets spreadsheet with nutrition data
  • To maintain and improve the Service's functionality
  • To respond to your questions and provide customer support

3.2 AI Processing

Your messages and images are processed using AI and machine learning technologies to:

  • Recognize ingredients from images
  • Extract nutritional information from text descriptions
  • Estimate calorie and macronutrient content
  • Understand natural language queries about nutrition

This processing may involve sending your messages and images to third-party AI service providers (such as OpenAI, Google AI, or similar services) for analysis. These providers are bound by their own privacy policies and terms of service.

We do not use your content to train our own machine learning models. Where available, we configure third-party providers so that content processed via their APIs is not used to train their models beyond what is necessary to provide the Service.

3.3 Service Improvement

  • To analyze usage patterns and improve the Service's accuracy
  • To fix bugs and technical issues
  • To develop new features and functionality

3.4 Communication

  • To send you important updates about the Service
  • To respond to your inquiries and provide support
