Visual Snow Simulator

**Decode Your Vision. Quantify Your Data.**

The Visual Snow Data Project is an advanced, open-source tool designed for individuals living with Visual Snow Syndrome (VSS). This application moves beyond subjective descriptions, providing a clinical-grade simulation engine and a comprehensive symptom-tracking suite to help patients and researchers find patterns in the noise.

#### 👁️ CLINICAL-GRADE SIMULATION ENGINE
Recreate your exact visual experience with 30+ adjustable parameters.
* **Dynamic Static:** Tune opacity, grain size, and flicker speed.
* **Noise Patterns:** Choose between Random, Circular, Brownian, and Linear motion patterns.
* **Entoptic Suite:** Accurate models for Floaters (physics-based) and the Blue Field Phenomenon (Scheerer's).
* **Complex Distortions:** Replicate Photopsia (flashes), Diplopia (double vision), Glare (starbursts), and Visual Vibration.
* **Neural Anomalies:** Simulate Migraine Aura (Scotoma) and Palinopsia (afterimages).

#### 📊 THE CORRELATION ENGINE (Symptom Logging)
Standardize your daily tracking by correlating visual noise with lifestyle variables.
* **Standardized Scales:** Integrated PHQ-9 depression scale, energy levels, and anxiety tracking.
* **Lifestyle Variables:** Track sleep duration (hours), stress intensity, and personal triggers to find patterns in your symptoms.
* **Clinical Exports:** Generate professional PDF reports of your visual configurations and symptom trends to share with your neurologist.

#### 👂 AUDITORY SYMPTOMS
* **Tinnitus Matcher:** Synthesize audio frequencies to match the pitch and volume of your ringing, helping you document your multi-sensory experience.

#### 🛡️ PRIVACY FIRST: ZERO-KNOWLEDGE
Your journey is yours alone.
* **No Data Collection:** We do not collect, transmit, or store any of your data on external servers.
* **No Internet Access:** The app does not request internet permissions—it is technically incapable of sending data off your device.
* **Local Storage:** Your logs stay strictly in your device's private storage. You remain in full control of your exports.
* **Complete Deletion:** You can delete all your data at any time using the "Delete All Data" feature. Uninstalling the app permanently removes all associated health logs from your device.

#### 🚀 MISSION: STANDARDIZATION
Visual Snow remains a puzzle because subjective descriptions vary. By using this tool, you are choosing to standardize your data. Whether you’re using it for personal symptom management or contributing anonymized reports to research, you're helping us turn "noise" into "knowledge."
