Contact: stephanchirinian@kornerstoneindustries.com

NutriCise AI is a nutrition, fitness, and wellness application that helps users track meals, exercise, goals, progress, and receive AI-powered nutrition and workout guidance. This Privacy Policy explains what information we collect, how we use it, when it may be shared with third-party services, and what choices you have.

NutriCise AI is not a medical device and does not provide medical advice, diagnosis, or treatment. The app is intended for general wellness, nutrition, and fitness support only.

1. Information We Collect

NutriCise AI may collect information that you provide directly, information generated through your use of the app, and information you choose to share through device permissions.

Account Information

When you create or use an account, we may collect:

  • Email address

This information is used to track nutrition, calculate progress, evaluate whether foods support your stated goals, and provide personalized nutrition guidance.

Exercise and Workout Data

When you log workouts or use exercise features, we may collect:

  • Exercise names

  • Calories burned

  • Duration

  • Workout type

  • Intensity

  • Sets and reps

  • AI-generated workout recommendations

This information is used to track fitness activity, recommend workouts, and personalize exercise plans based on your goals.

Goal and Profile Data

You may choose to provide information such as:

  • Fitness or nutrition goals

  • Weight

Health Data

If you choose to connect Apple Health, NutriCise AI may request permission to read certain HealthKit data, such as:

  • Workouts

  • Active energy burned

  • Resting energy burned

  • Resting heart rate

  • Respiratory rate

  • Sleep analysis

  • Body measurements, if enabled

Health data is used to personalize nutrition and workout recommendations, estimate energy balance, and provide progress insights. NutriCise AI only accesses Health data after you grant permission through Apple’s Health permission prompt. You can manage or revoke Health permissions at any time in the iOS Health app or Settings app.

NutriCise AI does not sell Health data.

Photos, Camera, and Image Data

If you use camera or photo library features, the app may access:

  • Photos you choose from your photo library

  • Images you capture with your camera

  • Meal or nutrition label images

  • Image-derived text or descriptions

Camera and photo library access is used only for features such as meal analysis, nutrition label scanning, or AI-based food description. The app does not access your full photo library unless you grant permission, and it only uses images you select or capture.

We may collect limited app usage and device-related information, such as:

  • App feature usage

  • Crash or diagnostic information

  • Device type

  • Operating system version

  • Notification preferences

2. AI Features and Third-Party AI Data Sharing

NutriCise AI includes AI-powered features that may help users with nutrition analysis, food ratings, meal suggestions, macro targets, exercise recommendations, daily summaries, and AI coaching.

When you choose to use an AI feature, NutriCise AI may send certain information to a third-party AI service in order to generate a response.

Third-Party AI Service Used

NutriCise AI uses OpenAI to provide AI-generated responses. User requests are routed through our secure Supabase Edge Function backend before being sent to OpenAI. OpenAI states that API data is not used to train its models by default for business/API customers unless the customer opts in.

Data That May Be Sent to OpenAI

Depending on the AI feature you choose to use, the following data may be sent to OpenAI through our Supabase backend:

  • Your written goal or fitness/nutrition objective

  • Food names, calories, protein, carbs, and fat values

  • Exercise names, duration, intensity, and calories burned

  • Meal descriptions

  • Food or nutrition label text recognized from images

  • Images or image-derived data when you choose to analyze a meal photo

  • Health-related context you choose to use for personalization, such as workout activity, sleep, or energy information

  • Your question or chat message to the AI coach

  • Relevant app context needed to generate a useful response

NutriCise AI does not intentionally send unnecessary personal identifiers to OpenAI. However, if you type personal information into an AI prompt, upload an image containing personal information, or include personal details in your goals, that information may be included in the AI request.

User Permission Before AI Sharing

Before NutriCise AI sends personal data to a third-party AI service, the app will explain:

  • What data may be sent

  • That the data may be sent to OpenAI

  • That the data is sent through Supabase Edge Functions

  • That the AI response is generated by a third-party AI provider

  • That the user can decline and avoid using AI features

AI features are optional. If you do not consent to AI data sharing, you should not use AI-powered features that require sending data to OpenAI.

Apple’s App Review Guidelines require apps to clearly disclose third-party AI data sharing and obtain permission before sharing personal data with third-party AI services.

3. How We Use Your Information

NutriCise AI uses collected information to:

  • Create and manage your account

  • Save and sync food, exercise, and goal data

  • Provide calorie and macro tracking

  • Generate nutrition targets

  • Generate workout recommendations

  • Analyze meal photos or nutrition labels

  • Provide AI-powered explanations and coaching

  • Display daily summaries and progress insights

  • Support reminders, notifications, and motivation features

  • Restore purchases and subscription access

  • Provide referral-code tracking

  • Improve app functionality and reliability

  • Prevent abuse, fraud, or misuse

  • Comply with legal and App Store requirements

4. Third-Party Services We Use

NutriCise AI may use third-party services to operate the app.

Supabase

We use Supabase for backend infrastructure, authentication, database storage, and Edge Functions. Supabase may process account data, saved app data, goals, food logs, exercise logs, and AI request routing. Supabase explains that its services involve the collection, use, and disclosure of personal information in connection with its platform.

Supabase Edge Functions are used to securely call OpenAI without placing the OpenAI API key inside the app.

OpenAI

We use OpenAI to generate AI-powered responses for nutrition, food, workout, and coaching features. Data is sent to OpenAI only when needed to provide AI functionality and after user permission is requested in the app.

OpenAI states that API data is not used to train its models by default for business/API users unless the organization explicitly opts in.

Firebase

NutriCise AI may use Firebase services, including Firebase Authentication and Firestore, for account authentication, cloud data storage, and syncing. Firebase provides privacy and security information for developers using its services.

Apple HealthKit

If you grant permission, NutriCise AI may read selected Apple Health data. HealthKit permissions are controlled by Apple’s system permission prompts and can be changed at any time in iOS Settings or the Health app.

StoreKit and App Store Purchases

NutriCise AI uses Apple StoreKit to process subscriptions, purchases, free trials, offer codes, and subscription entitlements. Payment information is handled by Apple, not directly by NutriCise AI.

Google Mobile Ads

If ads are enabled in the app, Google Mobile Ads may collect or process advertising-related data according to Google’s policies and your device settings. Ads may be personalized or non-personalized depending on your choices, device settings, and applicable law.

Open Food Facts

If you search for foods or scan barcodes, NutriCise AI may retrieve product and nutrition information from Open Food Facts or a similar public food database.

5. Data Sharing

We do not sell your personal information.

We may share data only in the following situations:

  • With Supabase to store and sync app data

  • With Firebase to support account and cloud-sync functionality

  • With OpenAI when you choose to use AI-powered features and consent to AI data sharing

  • With Apple to process subscriptions and purchases

  • With Google Mobile Ads if ads are shown in the app

  • With food database providers when searching or scanning foods

  • When required by law, legal process, or to protect app security

  • With service providers that help operate the app under appropriate privacy and security obligations

6. AI Consent and Control

AI features are optional. You can choose whether to use features such as:

  • AI food rating

  • AI meal analysis

  • AI macro generation

  • AI workout planning

  • AI coach/chat

  • AI daily summaries

  • AI image analysis

Before using AI features that send personal data to OpenAI, NutriCise AI will ask for your permission. If you decline, AI-powered features that require third-party AI processing may not function, but non-AI tracking features may still be available where supported.

You should avoid entering highly sensitive information into AI prompts unless you are comfortable with that information being processed to generate a response.

7. Health and Wellness Disclaimer

NutriCise AI provides general nutrition, fitness, and wellness information. It does not replace a doctor, registered dietitian, nutritionist, personal trainer, or other qualified professional.

You should consult a qualified healthcare professional before making major changes to your diet, exercise routine, medications, or health plan, especially if you:

  • Have a medical condition

  • Have a history of eating disorders

  • Are pregnant

  • Have an injury

  • Are taking medication

  • Have been advised to follow a specific medical diet or exercise restriction

8. Notifications and Reminders

NutriCise AI may send notifications if you allow them, including:

  • Meal logging reminders

  • Workout reminders

  • Motivation messages

  • Goal reminders

  • Daily summaries

  • Achievement notifications

You can manage notification permissions in iOS Settings.

9. Referral Features

NutriCise AI may include referral features that allow users to share invite codes or links. Referral codes may be used to track signups, rewards, badges, leaderboard status, or eligibility for Apple-approved promotional offers.

Referral codes do not directly unlock paid digital features unless redeemed through Apple-approved subscription mechanisms such as App Store offer codes or StoreKit promotional offers.

10. Subscriptions, Purchases, and Promo Codes

NutriCise AI may offer paid subscriptions or premium features through Apple In-App Purchase. Purchases are processed by Apple.

If NutriCise AI provides promo codes, offer codes, or subscription discounts, they must be redeemed through Apple’s official App Store or StoreKit redemption flow. The app does not use custom codes to directly unlock paid features outside Apple’s In-App Purchase system.

11. Data Storage and Security

We use reasonable technical and organizational safeguards to protect user data. However, no system can guarantee complete security.

Data may be stored locally on your device and/or synced to cloud services such as Supabase or Firebase. Supabase states that it provides tools such as access policies to help protect data, and Supabase reports SOC 2 Type 2 compliance for its platform.

You are responsible for keeping your account credentials secure.

12. Data Retention

We retain information for as long as needed to:

  • Provide the app

  • Maintain your account

  • Sync your data

  • Provide AI and tracking features

  • Comply with legal obligations

  • Resolve disputes

  • Enforce agreements

  • Maintain security

You may request deletion of your account or data by contacting us.

Some data may remain in backups, logs, or service-provider systems for a limited period as required for security, legal, or operational reasons.

13. Your Choices and Rights

Depending on your location, you may have rights to:

  • Access your personal data

  • Correct inaccurate data

15. International Data Processing

Your information may be processed in the United States or other countries where our service providers operate. These countries may have data protection laws different from those in your location.

By using NutriCise AI, you understand that your data may be processed by service providers such as Supabase, Firebase, OpenAI, Apple, and Google where they operate their services.
