Privacy Policy for LiftZone Workouts

Last Updated: January 8, 2026

1. Introduction

LiftZone Workouts (the "App") is a biomechanical fitness platform providing two distinct training experiences: Dynamic AI Personalization and Workout-Ready Library Programs. We are committed to a "Privacy-First" architecture. This policy explains our "Developer-Blind" data model, which ensures that your personal training and health data remains under your exclusive control.

2. The "Developer-Blind" Data Model

Unlike traditional fitness applications that collect and store your data on their own servers, LiftZone Workouts utilizes Apple CloudKit technology.

• Zero Access Storage: Your workout history, profile metrics, and nutrition logs are stored in your private iCloud database.

• Encrypted Sync: Data is encrypted by Apple and synced only across your authorized devices.

• No Collection: We, the developers of LiftZone Workouts, do not have access to, nor do we store your personal information on any servers owned or managed by us. We cannot see your weights, photos, or health data.

3. Data Usage Distinction

While we do not "collect" your data, the App processes it locally and within your private iCloud container to provide functional intelligence:

• Dynamic AI Coaching: For users on the AI Plan, the App processes your AMRAP (As Many Reps As Possible)performance and exercise history locally. Our algorithm uses the Epley Formula to recalibrate your Estimated One Rep Max (e1RM) to ensure progressive overload in future sessions.

• Workout Library: For Library programs, the App processes your selection and custom scheduling preferences to overlay professional blueprints onto your calendar.

• On-Device AI Processing: Features such as the AI Meal Scanner process images locally on your device. We do not see or store the images you scan.

4. Optional HealthKit Integration

With your explicit permission, the App views specific data from Apple HealthKit (e.g., heart rate, steps) to populate your Activity Dashboard. This data is used for display purposes only and is never transmitted to us or any third party.

5. Third-Party Service Providers

We limit third-party involvement to essential infrastructure:

• Apple CloudKit: Provides secure, private data synchronization.

• RevenueCat: Manages subscription status anonymously. We do not collect or store your payment details; all transactions are handled securely by the Apple App Store.

6. Your Rights and Data Control

• Access & Modification: You can update your profile metrics directly within the App at any time.

• Irreversible Deletion: You maintain full ownership of your data. You may permanently delete your profile and all associated history through the "Reset App Data" option in the App Settings. This action immediately removes all records from both your local device and your private iCloud container.

7. Children's Privacy

LiftZone Workouts is not intended for use by children under the age of 13. We do not knowingly collect or have access to any personal information from children.

8. Legal Disclaimer

LiftZone Workouts provides fitness and nutrition information for educational purposes. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult with a healthcare professional before starting any new exercise program.
