Store description excerpt

Lumen: Your Silent Guardian for Mental Health Lumen is a next-generation behavioral health tool that identifies the early warning signs of mental health risks—entirely through passive, on-device sensing. Unlike traditional apps that require you to manually log your mood every day, Lumen works silently in the background, allowing you to focus on your life while it watches your back. *** IMPORTANT: ACCESSIBILITY SERVICE API USAGE DISCLOSURE To support its core wellness features, Lumen makes use of Android’s AccessibilityService API: • Why We Use It: Lumen analyzes fine-grained digital interaction rhythms (psychomotor dynamics) to establish your personal behavioral baseline and detect subtle changes that can signal changes in your well-being. • Specific Features Enabled: We measure typing speed (characters typed per second), deletion patterns (backspace usage ratio), and scroll velocity. • Data Access & Privacy: - NO TEXT CONTENT IS READ: We strictly measure the speed, rate, and rhythms of your interactions. Lumen NEVER reads, records, or stores the actual text content of your keystrokes, messages, or input fields. - SECURITY GUARDRAILS: Password fields and sensitive inputs are automatically detected and completely skipped. - 100% ON-DEVICE & PRIVATE: All interaction metrics are processed entirely on-device and stored locally in your app's private sandbox. Absolutely no data accessed via the AccessibilityService API is shared, transferred, or uploaded off the device. *** How It Works: The "Idiographic" Advantage Most systems compare you to a population average. Lumen is different. It recognizes that everyone’s "normal" is unique. The Baseline: For the first 28 days, Lumen establishes your personal behavioral fingerprint—learning your unique patterns of sleep, mobility, and communication. Continuous Monitoring: Once your baseline is set, Lumen monitors for sustained deviations from your "personal normal". Texture Analysis: Beyond just counting steps or screen time, Lumen analyzes "behavioral texture"—the subtle ways you interact with your phone that can signal changes in mental well-being. Key Features: Fully Passive: No daily surveys, no mood logging, and no manual data entry required. Just install and forget. Privacy-First Design: All analysis happens on your phone. Your raw behavioral data never leaves your device. Sustained Evidence Engine: To prevent false alarms, Lumen only alerts you when it detects meaningful, multi-day shifts in your patterns. Tiered Observations: Receive gentle "pattern awareness" notifications or recommendations for professional consultation based on the level of behavioral drift detected. A Science-First Approach Lumen is built on established clinical research regarding digital phenotyping and behavioral biomarkers. By analyzing 29 distinct features—including sleep duration, mobility entropy, and social engagement—Lumen provides a comprehensive view of your behavioral health without ever being intrusiv
