AI Usage Policy

Last Updated: June 26, 2026

This AI Usage Policy describes how artificial intelligence is used within the GetFit mobile application operated by KeyZen.

1. AI Features in GetFit

GetFit incorporates the following AI-powered features:

A conversational AI fitness and nutrition coach available to Kyro Pro+ subscribers
Provides personalized workout advice, nutrition guidance, motivation, and answers to fitness-related questions
Adapts its communication style and recommendations based on your profile, conversation history, and stored memories

Generates personalized diet plans based on your health profile, fitness goals, dietary preferences, allergies, health conditions, cuisine preferences, cooking time, and budget
Calculates appropriate calorie targets and macro distributions

Identifies food items from photos captured by your device camera
Estimates nutritional content (calories, protein, carbs, fat) of identified foods
Supports identification of multiple food items in a single image

The AI Trainer extracts and stores factual information from your conversations (e.g., "has a knee injury," "prefers morning workouts," "is vegetarian")
Memories are categorized by type: injury, goal, preference, body stats, experience, limitation, achievement, routine, nutrition, progress
Memories have a hierarchical system:
- Level 1 (Core Identity): Very slow decay — allergies, chronic injuries, fundamental preferences
- Level 2 (Long-term Evolving): Medium decay — weight, routines, progress
- Level 3 (Short-term Context): Fast decay (24-72 hours) — temporary states like soreness, travel
- Level 4 (Session): Destroyed when the chat session ends

The AI maintains a "User State" that tracks inferred metrics such as energy, recovery, fatigue, motivation, adherence, injury risk, burnout risk, and plateau risk
These metrics are used to adjust AI coaching recommendations (e.g., suggesting deload periods when fatigue is high, simplifying plans when adherence is low)
The AI may predict behavioral patterns such as likely plan abandonment, motivation drops, or readiness for progression

GetFit uses a custom self-hosted AI model for all AI features
The AI service processes your data in real-time and does not share your data with third-party AI providers (e.g., OpenAI, Google, Anthropic)
Food recognition uses computer vision models to identify food items from images
The AI model is hosted on infrastructure controlled by KeyZen

The AI features use the following data to provide personalized responses:

Data Type	How Used
Your profile (name, age, gender, weight, height, goal, diet preference)	Personalizing recommendations
Your subscription tier	Determining available AI features
Chat messages you send	Generating relevant responses
AI-extracted memories	Providing context-aware coaching
Food images (camera captures)	Identifying food items
Exercise videos (user-submitted)	Analyzing exercise form
User state signals (workout logs, meal logs, feedback)	Adapting coaching intensity and tone

You have full control over your AI data:

View memories: See all facts the AI has stored about you
Delete individual memories: Remove specific facts you don't want the AI to remember
Confirm memories: Verify AI-extracted facts for higher accuracy
Reset all memories: Clear your entire AI memory profile
Export memories: Download all AI memories associated with your account
Delete chat sessions: Remove conversation history
Delete account: Removes all AI data permanently

⚠️ IMPORTANT: The AI is NOT a medical professional, licensed dietitian, certified personal trainer, or healthcare provider.

AI responses are for informational and educational purposes only
AI-generated diet plans, calorie recommendations, and fitness advice are estimates based on general formulas and may not be appropriate for your specific medical conditions
Always consult a qualified healthcare professional before making significant changes to your diet or exercise routine

AI food recognition may misidentify foods or provide inaccurate nutritional estimates
AI diet plans may not account for all medical conditions, medication interactions, or individual nutritional needs
AI exercise form analysis may miss critical form errors that could lead to injury
AI memory extraction may misinterpret or misremember facts from conversations

The AI Trainer is not a substitute for:

You are solely responsible for:

Verifying the accuracy of AI-generated information before acting on it
Disclosing relevant health conditions and allergies when interacting with the AI
Discontinuing any AI-recommended plan that causes adverse effects
Seeking professional advice for serious health, nutrition, or fitness concerns

Your conversations and data may be used to improve the AI model's accuracy for your own personalized experience
We do not use your personal data to train AI models that are shared with or used by other users
AI model improvements are focused on system-level quality, not individual user data exposure
You can opt out of AI data retention by deleting your AI memories and chat history

We implement the following safety measures:

Memory validation: AI-extracted memories are validated before storage to prevent erroneous facts
Memory quarantine: Uncertain or emotionally-driven facts are quarantined and require verification
Contradiction detection: The AI resolves conflicting memories to maintain accuracy
Truth decay: Memory confidence scores decay over time if not reinforced, ensuring outdated information fades
Rate limiting: AI endpoints are protected against abuse
Content filtering: The AI is designed to refuse requests for harmful, abusive, or medically dangerous advice

We may update, modify, or discontinue AI features at any time. We will notify users of material changes through the App.
