Privacy Policy

Marczell Klein Corp · Last updated: March 13, 2026

Marczell AI ("we," "us," or "our") operates the Marczell AI mobile application and website (collectively, the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service.

1. Information We Collect

Personal Information

When you create an account, we collect:

Name, email address, and phone number
Age and timezone
Authentication credentials (stored securely via our authentication provider)

Behavioral and Wellness Data

Our Service collects and processes behavioral and wellness-related data to provide personalized coaching and audio experiences. This includes:

Self-assessment responses: Answers to onboarding questions about your goals, limiting beliefs, emotional patterns, and self-ratings across life areas (wealth, health, relationships)
Behavioral profile data: AI-generated identity scores across six dimensions — identity, emotional stability, confidence, execution, decision clarity, and self-awareness — derived from your self-reported responses
Coaching conversation content: Messages exchanged during daily coaching sessions and open-ended coaching conversations
Behavioral analysis: AI-generated insights including cognitive patterns, behavioral loops, and psychological narratives, all based on your voluntary responses
Progress tracking: Changes in your identity scores over time, session streaks, and milestone achievements
Instagram profile analysis: If you use this optional feature, screenshots you upload and the resulting personality analysis

Important: Marczell AI is not a medical or mental health service. The behavioral data we collect is based entirely on your voluntary self-reported responses and AI-generated coaching insights. It is not clinical, diagnostic, or medical data.

3. How We Share Your Information

Operate under their respective privacy policies and data processing agreements
Do not use your data for model training when accessed via their API services

Legal Disclosures

We may disclose your information if required by law, legal process, or government request, or to protect the rights, property, or safety of Marczell Klein Corp, our users, or others.

4. Data Security

We implement industry-standard security measures to protect your data:

All data is encrypted in transit (TLS/HTTPS) and at rest
Database access is protected by row-level security — users can only access their own data
Administrative access is restricted to authorized personnel with role-based access controls
API endpoints are rate-limited to prevent abuse
User input is sanitized to prevent injection attacks

No method of transmission over the internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your data, we cannot guarantee absolute security.

Behavioral profiles and coaching conversations: Retained for the duration of your active subscription to provide continuity in your coaching experience
