4. AI Model Transparency

MacrosGPT uses artificial intelligence ("AI") to help you track your nutrition, estimate calories, analyze your habits, and provide personalized insights. This section explains how your data interacts with AI systems.

A. AI Provider Independence

MacrosGPT is an independent product and is not affiliated with, endorsed by, or associated with OpenAI, ChatGPT, or any other AI company. The term "GPT" in "MacrosGPT" refers to the app's use of generative AI technology for nutrition coaching and does not imply any partnership or connection with OpenAI or its products.

B. How MacrosGPT Uses AI

Artificial intelligence is used throughout the app to provide:

• Calorie and macro estimation
• Food identification (via photo uploads)
• Personalized nutrition insights
• Progress analysis
• Habit recommendations
• AI chat interactions and coaching

C. What Data the AI May Access

To function properly, the AI may use:

• Age, height, weight, activity level
• Goal weight and progress metrics
• Nutrition logs (foods, macros, calories)
• Exercise logs
• Food photos (deleted after 24 hours)
• AI chat logs (stored locally on-device for up to 90 days)

D. Use of Data for AI Training

By using MacrosGPT, you agree that your data may be used to train and improve our AI models. This may include:

• Nutrition logs
• Weight and progress data

Training data helps improve calorie estimation, food recognition, and personalized recommendations. Whenever possible, training data is anonymized, aggregated, and stripped of personal identifiers. You may delete your account at any time to remove future use of your data in training.

E. Where AI Processing Occurs

AI models may run:

• On cloud servers (primary)

AI outputs may not always be accurate, complete, or reliable. You should independently verify all nutrition or health decisions.

In limited cases, anonymized data may be reviewed by a human solely to:

• Improve AI accuracy
• Evaluate training quality
• Fix system errors

No personal identifiers are shared during this process.

H. Photos & Camera Usage

• Food photos are deleted within 24 hours
• We do not store photos long-term
• Photos may be used for AI training only after being anonymized
• No biometric identification is performed
• No face recognition or identity tracking is performed
• The camera is used only for food logging
