PixelAnalyzer

PixelAnalyzer analyzes photos entirely on your device. We do not collect, store, or transmit any personal data, images, or analysis results to any server or third party.

🚫 Data We Do Not Collect

PixelAnalyzer does not collect, transmit, or share any of the following:

• Photos or images
• Face data or biometric information
• Device identifiers or advertising IDs
• Location data
• Usage analytics or crash reports
• Any personally identifiable information

👤 Face Data

The app uses Apple's Vision framework to detect faces in images you select. The following applies to all face data:

• What is detected: Face bounding box, count, and pose angles (roll, yaw, pitch). No identity or biometric data is derived.
• Purpose: Results are displayed on-screen to you as part of the image analysis only.
• Storage: Face detection results are never written to disk. If you save an analysis to history, only a thumbnail image and basic metadata (date, source) are stored locally on your device.
• Sharing: Face data is never shared with any third party, uploaded to any server, or used for any purpose other than displaying the result to you.
• Retention: On-screen results exist only in memory and are discarded when you leave the screen. Saved history can be deleted at any time from Settings → Delete All Data.

⚙️ On-Device Processing

All analysis is performed locally on your device using Apple's built-in frameworks:

• Vision — face detection, object recognition, text recognition (OCR), barcode scanning
• Core Image / Accelerate — color analysis, histogram, quality metrics
• ImageIO — EXIF metadata extraction

This app makes no network requests of any kind. Your images never leave your device.

🤖 No Third-Party AI Services

PixelAnalyzer does not use any third-party AI or cloud service (such as OpenAI, Google Cloud Vision, AWS Rekognition, or similar). All intelligence features are powered exclusively by Apple's on-device frameworks.

💾 Local Storage

If you choose to save an analysis to history, the following is stored locally on your device using NSUserDefaults:

• A small thumbnail of the image (max 200 × 200 px, JPEG)
• Analysis date and image source label (e.g. "Camera", "Photo Library")
• Dominant color hex values

This data never leaves your device. You can delete all stored data at any time from Settings → Delete All Data.

🔐 Permissions

• Camera: Used only when you tap "Take a Photo". Not accessed at any other time.
• Photo Library (read): Used only when you tap "Choose from Library". Not accessed at any other time.
• Photo Library (write): Used only if you choose to export an annotated image.
• Clipboard: Read only when you tap "Paste from Clipboard". Not accessed automatically.
