1. Introduction
Welcome to Gainzi ("we," "our," or "us"). This Privacy Policy explains how we collect, use, store, and protect your information when you use the Gainzi iOS application and related services (collectively, the "Service").
By using Gainzi, you agree to the collection and use of information in accordance with this policy. If you do not agree, please do not use the Service.
If you have questions about this policy or your data, contact us at GainziApp@gmail.com.
2. Information We Collect
We collect the following categories of information:
Account Information
If you create an account, we may collect an email address and any optional profile information you choose to provide (such as a display name). The specific information collected depends on how you sign up and what you choose to share.
Physique Photos
To provide the core analysis features of the Service, you voluntarily upload photos of your physique. These photos are transmitted securely to our servers for AI-powered analysis. Photos are associated with your account and stored to enable progress tracking over time.
Analysis and Fitness Data
We store the results of your physique analyses, including muscle scores, physique scores, symmetry ratings, and training recommendations, to enable progress tracking and provide historical comparisons.
Device and Usage Data
We may automatically collect information about your device (such as device model, operating system version, and unique device identifiers) and usage patterns (such as features accessed and session duration) for the purposes of improving the Service, diagnosing issues, and analytics.
Payment Information
Subscription purchases are processed through Apple's App Store. We do not collect or store your payment card information. Apple handles all payment processing in accordance with their own privacy policy.
Support Communications
If you contact us for support, we may collect your name, email address, and any information you provide in your message.

5. AI Photo Analysis & Third-Party Processing
The core feature of Gainzi analyzes photos of your physique using artificial intelligence. This section explains exactly what you provide, where your photos go, who processes them, and the limits we place on their use.
What You Provide
To use the analysis feature, you select existing photos from your device's photo library or capture new photos with your camera. A complete analysis uses front, side, and rear body photos that you choose to provide.
Where Your Photos Are Sent
When you request an analysis, your front, side, and rear photos may be securely transmitted, over encrypted connections, to Gainzi's backend infrastructure and to OpenAI. OpenAI is the third-party artificial intelligence provider that performs the visual analysis of your photos on our behalf.
How Your Photos Are Used
Your photos are processed solely to generate your analysis results, which include:
- Your overall physique score
- A muscle-by-muscle breakdown
- Symmetry ratios
- Identified strengths
- Identified weak points
- Personalized training recommendations
Limits On Use
- Your photos are used only to provide the physique analysis feature.
- Your photos are never sold to anyone.
- Your photos are never used for advertising.
- Your photos are not used to train AI models.
6. Data Storage and Security
Your data is stored on secure cloud infrastructure. We implement industry-standard security measures, including:
- Encrypted data transmission (TLS/HTTPS)
- Encrypted data storage at rest
- Access controls and authentication requirements
- Regular security monitoring and vulnerability assessments
No method of transmission over the internet is 100% secure. While we strive to protect your data, we cannot guarantee absolute security. If you believe your account has been compromised, contact us immediately at GainziApp@gmail.com.
We retain your data for as long as your account is active or as needed to provide the Service. You can delete your account and associated data at any time from within the app.
7. Third-Party Services
We use trusted third-party services to help operate the Service. These providers may process certain categories of your data on our behalf and are bound by data processing agreements:
- Apple App Store — subscription billing and payment processing
- Cloud infrastructure providers — secure storage and computation
- Analytics or crash reporting services (where used) — aggregated usage and performance data
We do not sell or rent your personal information to third-party advertisers or data brokers.
8. Subscriptions and Payments
Gainzi offers subscription plans that unlock premium features. All purchases are made through the Apple App Store and are subject to Apple's terms and conditions.
We do not directly process or store payment information. Apple handles all billing. For refund requests or billing issues, please contact Apple directly at reportaproblem.apple.com.
Subscription auto-renewal and cancellation are managed through your Apple ID settings. Cancelling a subscription does not delete your account or analysis history.
9. Children's Privacy
The Service is not directed to children under the age of 13 (or the applicable minimum age in your jurisdiction). We do not knowingly collect personal information from children under 13. If we learn that we have collected such information, we will promptly delete it. If you believe a child has provided us with personal information, please contact us at GainziApp@gmail.com.
