Rynox - Privacy Promise

💻

Our Local-First Philosophy

Unlike most fitness applications that require constant internet connectivity and store your sensitive information on remote servers, Rynox takes a radically different approach. We have designed every aspect of the application to function entirely on your device.

📈 Training Sessions

Every jump count, duration, pace calculation, and calorie estimate is stored locally in an encrypted SQLite database on your device. This information never leaves your phone.

📸 Body Photos

Your transformation photos are stored in your device's private app directory with restricted access. We do not upload these images to any cloud service, server, or third-party storage platform.

🏅 Achievements & Progress

Your unlocked moves, earned points, and achievement badges are all recorded locally. Your milestones belong to you alone.

This local-first architecture means that even if our company ceased to exist tomorrow, your data would remain safely on your device, fully accessible to you.

🛠

What Information We Handle

When you use Rynox, the application processes the following types of information entirely on your device:

Workout Metrics: Jump counts, session durations, rest intervals, pace calculations, and estimated calories burned based on your input.
Physical Markers: Optional records including weight, body fat percentage, heart rate readings, fatigue levels, mood indicators, and muscle soreness notes.
Visual Records: Photos you choose to take or upload to track your physical transformation over time.
App Preferences: Your customized settings including daily goals, notification preferences, and display options.
Progress Data: Statistics used to generate charts, streak calculations, and achievement unlocks.

What We Absolutely Do Not Do

Zero Data Collection Policy
We want to be crystal clear about what separates Rynox from other fitness applications. Here is our commitment to you:

We do not collect personal identifiers such as your name, email address, phone number, or location data.
We do not operate servers that store your workout history or body photos.
We do not track your app usage patterns, screen time, or feature interactions.
We do not share, sell, rent, or trade any information with third parties, advertisers, or data brokers.
We do not use analytics tools that transmit your behavior data to external services.
We do not require account creation, social login, or authentication credentials.

How We Protect Your Data

Your privacy is protected through multiple layers of security built into the application:

🗂

SQLite Encryption

🎨

Secure Storage

🔒

No Network Calls

✅

Local Processing

All data processing happens on your device. The app does not make network requests to transmit your workout data. Your photos are compressed and stored using your device's native security protections.

💡

Your Control Over Your Data

We believe you should have complete autonomy over your information. Rynox provides you with full control:

📤 Export Your Data

Generate comprehensive summaries of your training history, complete with statistics and progress charts, saved directly to your device storage.

📥 Backup & Restore

Create encrypted backup files of your entire Rynox database that you can store in your preferred cloud storage or transfer to a new device.

🗑 Complete Deletion

Permanently erase all stored data with a single action in the settings menu. Uninstalling the app also removes all associated data from your device.

🔧

Optional Features & Permissions

Rynox requests certain device permissions only when specific features are used:

Camera Access: Requested only when you choose to take a body progress photo within the app. You can deny this permission and still use all other features.
Photo Library Access: Requested only when you choose to import a photo from your gallery. This permission can be revoked at any time.
Storage Access: Used solely for saving exported data files or backup files to your chosen location.

All permissions are optional. Rynox functions fully as a workout tracker without granting any permissions, though photo tracking features will be unavailable.

Updates To This Promise

As Rynox evolves, we may update this Privacy Promise to reflect new features or improvements. Any changes will be communicated through app update notes. Our core commitment to local-only data storage and zero collection will never change.

By continuing to use Rynox after updates, you acknowledge the revised privacy terms. We encourage you to review this document periodically to stay informed about how we protect your information.
