Last updated: June 18, 2026

Thank you for choosing Nutrition Tracker - Food Diary (also known as Calibri) (referred to as “we,” “us,” or “our app”). We value your privacy and are committed to protecting your personal information. This Privacy Policy outlines the types of data we collect, how we use and protect it, your data retention timelines, and your rights regarding your information.

1. Information We Collect

To provide you with a seamless tracking experience and to synchronize your data across devices, we collect the following types of information:

  • Account & Authentication Data: When you create an account, we collect limited personal information necessary for secure access. This includes your email address or social login details (e.g., Google Sign-In, Apple ID) via Google Firebase Authentication.
  • App Usage Data (Calorie Tracking): We collect and store the data you directly input into the app, such as food logs, calorie consumption, and related nutritional metrics, to calculate insights and track your progress.
  • Analytical Data: We use third-party analytics tools—Google Analytics and Amplitude—to collect non-personal, anonymized usage statistics. This includes device info, operating system versions, and app event interactions (e.g., buttons clicked). This data helps us optimize app performance and fix bugs.

2. Use of Collected Information

We use the data we collect solely for the following purposes:

  • To provide, maintain, and improve the core functionalities of the app.
  • To authenticate your identity and keep your account secure.
  • To back up your food diary and sync your progress across your devices.
  • To analyze anonymous app performance metrics and troubleshoot crashes.

We do not sell, trade, or rent your personal data to third parties.

3. Data Retention and Deletion

We believe in giving you full control over your data. Our retention practices are as follows:

  • Account & Tracking Data: Your account credentials and calorie tracking data are stored securely in Google Firebase. This data is retained for as long as your account remains active so that you can access your history at any time.
  • User-Initiated Deletion: Your data is kept until you explicitly request its removal. You can delete your account and all associated data instantly at any time using the “Delete my account” feature located within the app’s settings. Alternatively, you can request account deletion by emailing us at [email protected]. Once an account is deleted, all associated user logs and personal credentials are permanently wiped from our active databases.
  • Analytics Data: Non-identifiable analytical data processed by Google Analytics and Amplitude is retained by those respective platforms in accordance with their standard, default data retention schedules.

4. Data Security & Limitations

We utilize industry-standard cloud infrastructure (Google Firebase) to host and secure your data. We implement reasonable administrative, technical, and physical measures designed to protect your information from unauthorized access, loss, or alteration.

However, please be aware that no method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your data, we cannot guarantee absolute security, and users acknowledge this inherent risk when using the app.

5. Data Breach Notification

In the event of a security breach that compromises your personal information, we will take immediate action to mitigate the impact. We are committed to notifying affected users and relevant regulatory authorities in a timely manner, in strict accordance with applicable local laws and regulations.
