Muscle Code

Smart fitness app where you are not the product.

Smart fitness—without the surveillance

Get science-based fitness guidance while keeping full control of your data. This app turns peer-reviewed research into practical insights—without accounts, ads, or tracking. Everything happens on your device, and your information never leaves it.

Why it’s different
• Privacy-first: No sign-up, no cloud sync, no trackers. Your data stays on your phone.
• No model training on your data: We don’t use your information to train AI—ever.
• Evidence-based: Features and recommendations are grounded in published studies; we cite sources where relevant.
• Free to use: Built to be useful and accessible from day one.

What you can do
• See research distilled into plain language so you can make informed choices about training, recovery, and habits.
• Track only what you want (workouts, metrics, notes) and keep it local—enable/disable modules anytime.
• Review clear trends and progress summaries computed on-device.
• Export or back up your data whenever you like, under your control.

What we don’t do
• No accounts or logins
• No ads, pushy prompts, or dark patterns
• No data collection, selling, or sharing
• No background uploads or analytics
• No training of models on your data

Who it’s for

Anyone who wants smart, research-backed fitness tools without giving up their privacy—athletes, beginners, coaches, and privacy-conscious users alike.

Transparency & control
• View exactly what’s stored and delete it at any time.
