FitLock: The Active App Blocker

Overview
FitLock is an innovative mobile productivity and digital wellbeing application designed to help users reduce their screen time and build healthier habits in a completely unique way. Instead of relying solely on traditional time limits, PIN codes, or simple willpower to restrict unproductive app usage, FitLock introduces a physical requirement: users must perform physical exercises to unlock their chosen applications. By transforming the impulse to mindlessly scroll into a mandatory opportunity for physical activity, FitLock effectively combats smartphone addiction while simultaneously promoting fitness.

How It Works
* App Selection: Users can proactively choose which applications on their device they find distracting or want to limit their time on (such as social media, games, or entertainment platforms).
* The Lock Screen: When a user attempts to open one of these protected apps, FitLock seamlessly intercepts the app launch and presents a professional lock screen.
* Exercise to Unlock: To bypass the lock screen and regain access to the application, the user must activate their device's camera and successfully complete a designated physical exercise challenge.
* Real-Time AI Verification: FitLock utilizes standard camera access alongside advanced, real-time AI motion tracking to verify that the required body movements are being performed correctly before granting access to the locked app.

Strict Privacy Guarantee
Because FitLock requires camera access to verify physical exercises, ensuring total user privacy is the foundational pillar of the app's architecture.
* 100% On-Device Processing: All camera feed analysis, pose detection, body tracking, and exercise verification occur strictly locally on the user's own device.
* Zero Data Collection: FitLock does not record, store, collect, process remotely, or upload any video footage, images, personal data, or biometric information to any external servers, cloud databases, or third parties. What the camera sees never leaves the phone.
* Transparent Notices: The app features a dedicated clear notice section inside the user profile, transparently explaining to users that no personal data is collected and all processing is handled purely on-device.

App Features and Monetization
FitLock offers a balanced feature set designed to be accessible while supporting ongoing development:
* Free Tier: The core functionality of FitLock is available for free, supported by the integration of standard mobile advertisements.
* Premium Subscription: Users looking for an enhanced experience can upgrade to a premium subscription. This tier removes advertisements and unlocks advanced app features.
* Device-Specific Subscriptions: To further protect privacy, FitLock does not require users to create personal accounts or log in. As a result, premium subscriptions are processed securely through Google Play Billing and are linked specifically to the user's device ID. This means the premium status is device-specific and functions securely without needing cross-device cloud synchronization.
* Streamlined UI: The user interface is heavily optimized for performance and fast load times (including lazy-loaded icons), providing a snappy, responsive experience right from startup.
