Privacy Policy

1. Who We Are

JustCalories is an iOS application developed and operated by Ievgen Mykhailov ("we", "us", or "our"). If you have any questions about this policy, contact us at [email protected].

2. What Data We Collect and Why

Food Photos

When you log a meal, you can take a photo with your camera or choose one from your photo library. That image is sent to our AI service at justcalories.app solely to estimate the meal's calories and macronutrients. We do not store your photos on our servers beyond the time required to process the request. Photos you have already logged are stored on-device in the app's private container.

Apple Health Data

With your permission, JustCalories reads the following from Apple Health:

• Active and basal calories burned (to show your energy balance)
• Dietary calorie and macronutrient samples you have previously logged

JustCalories writes the following to Apple Health when you log a meal:

• Dietary energy (calories)
• Dietary protein, fat, and carbohydrate (grams)

This data stays inside Apple Health on your device and is governed by Apple's privacy framework. We never transmit your Apple Health data to our servers.

App Preferences

We store your goals, dietary preferences, and Apple Health toggle states in your device's local storage (UserDefaults). These preferences never leave your device.

3. Data We Do Not Collect

• We do not require account registration or collect your name, email address, or any identifier.
• We do not use advertising networks or analytics SDKs.
• We do not track you across other apps or websites.
• We do not sell, rent, or share your data with third parties for marketing purposes.
• We do not collect your location.
• We do not collect device identifiers (IDFA, IDFV) for tracking.

4. How Your Data Is Stored

All meal records and logged nutrition data are stored locally on your device using Apple's SwiftData framework. Meal photos you have logged are stored in the app's private on-device container. No meal records or photos are uploaded to or stored on our servers.

If you delete the app, all locally stored data is deleted from your device. Any nutrition samples written to Apple Health remain there and must be removed through the Health app if you wish to delete them.

5. Third-Party Services

JustCalories uses the following third-party service to process meal photos:

• OpenAI (via our backend at justcalories.app) — meal photos are analysed by an AI model to estimate nutritional content. OpenAI's data handling is governed by OpenAI's Privacy Policy. We operate our own backend that proxies requests; we do not pass any personal identifiers to OpenAI along with your image.

No other third-party SDKs, analytics services, or advertising networks are included in the app.

6. Children's Privacy

JustCalories is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.

7. Your Rights

Because JustCalories does not collect personal data on our servers, there is no account or profile to request access to or deletion of. All data the app generates lives on your device and in Apple Health, both of which you control directly.

If you have questions or concerns, contact us at [email protected].

8. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Continued use of the app after changes are posted constitutes your acceptance of the updated policy.
