Privacy Policy for Hunger App

Last Updated: October 28, 2026

1. Introduction

This Privacy Policy applies to the Hunger App ("the App"), a mobile application available for Android via Google Play and for iOS via the Apple App Store. The App is developed and published by Volodymyr Smirnov, operating as an individual developer registered on the Google Play Developer Console (personal developer account, United Arab Emirates).

This Privacy Policy is linked on the App's Google Play Store listing and within the App itself. By using the App, you acknowledge that you have read, understood, and agree to the practices described in this Privacy Policy.

2. Information We Collect

The App collects the following categories of user data:

2.1 Health-Related Data

As a nutrition tracking application, the App collects health-related metrics that you provide, including but not limited to dietary intake, nutritional information, calorie counts, meal logs, and other health and wellness metrics you choose to enter.

2.2 User-Generated Content

The App stores all content you create within the App, such as custom meals, recipes, food entries, notes, preferences, and any other data you generate through your use of the App.

2.3 Device and Usage Information

The App may automatically collect certain technical information, including device type, operating system version, app version, language settings, and general usage statistics to improve performance and user experience.

2.4 Health Data (Health Connect and Apple Health)

Data the App reads. With your permission, the App reads the following data from Health Connect (Android) or Apple Health (iOS):

  • Weight
  • Height
  • Body-fat percentage
  • Active calories burned
  • Basal metabolic rate (resting energy)
  • Sex and age, where available

Data the App writes. With your permission, the App writes each meal you log to Health Connect or Apple Health as nutrition data: calories, protein, carbohydrates, fat, meal type, and time. If you edit or delete a meal in the App, the corresponding record is updated or removed.

How health data is used. Health data is used only to provide the following features to you:

  • Showing your weight in your profile.
  • Personalizing the suggested calorie goal and the daily "Hunger AI" insight, including your BMI and your energy balance (calories eaten compared with active and resting energy burned).
  • Showing your weekly energy balance and weight change in Weekly Progress.

Storage. Your latest body metrics and your daily energy totals (for the last 14 days synced) are sent over HTTPS to the App's servers and stored with your account.

AI processing. To write your insights, these metrics are sent to Google Gemini, which processes them on the App's behalf (see Section 4).

Limited Use. Health data is never used for advertising, never sold, and never used to build profiles for third parties. It is shared only as needed to provide the features described above. Hunger's use and transfer of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements. Information received from Apple HealthKit is not used for advertising and is not sold.

Your choices. You can deny or revoke the App's access at any time in Health Connect (Android) or the Health app (iOS). If you do, the App works from your food log alone. To delete health data already synced to the App's servers, see Section 8.

3. How We Use Your Information

Your information is used for the following purposes:

  • App Functionality: To provide, operate, and maintain the core features of the App, including tracking and displaying your nutrition data.
  • Content Storage: To store and retrieve the content you create within the App so it is available to you across sessions.
  • Improvement and Analytics: To analyze usage patterns, diagnose technical issues, and improve the App's performance and user experience.
  • Error Monitoring: To identify, diagnose, and resolve bugs, crashes, and other technical problems.

4. Third-Party Services

The App uses the following third-party services:

  • Sentry — Used for error tracking and crash reporting to help identify and fix technical issues. Sentry may collect device information, app state data, and error logs. For more information, see Sentry's Privacy Policy.
  • Cloudflare — Used for analytics, content delivery, and security purposes to improve the App's performance and user experience. Cloudflare may collect IP addresses, device information, and usage data. Meal photos are stored on Cloudflare R2. For more information, see Cloudflare's Privacy Policy.
  • Neon — Hosted Postgres database in which your account data is stored. For more information, see Neon's Privacy Policy.
  • Google Gemini (Google LLC) — Used for AI processing of meal photos, voice notes, typed meal descriptions, and health metrics to analyze your meals and write insights. Voice recordings are processed only to produce the analysis and are not stored by Hunger. For more information, see Google's Privacy Policy.
  • Auth0 (Okta) — Used for sign-in and account authentication. Auth0 processes your email address, name, and user ID. For more information, see Okta's Privacy Policy.
  • Google Play Services — Required for distribution through Google Play. Google may collect certain data as described in Google's Privacy Policy.

5. Data Sharing

Your personal data is not sold to third parties. Data may be shared only in the following limited circumstances:

  • With the third-party service providers listed above, solely for the purposes described in this policy.
  • When required by law, regulation, legal process, or enforceable governmental request.
  • To protect the rights, safety, or property of the developer, users, or the public as required or permitted by law.

6. Data Retention

Your health-related data, including health data synced from Health Connect or Apple Health, and user-generated content are retained for as long as you maintain your account. If you delete your account or request deletion of your data, your information will be removed in accordance with the procedures described in Section 8. Aggregated and anonymized analytics data may be retained for a longer period for the purposes of improving the App.

7. Data Security

We take reasonable measures to protect your information from unauthorized access, alteration, disclosure, or destruction. These measures include encryption of data in transit and secure storage practices. However, no method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.
