Overview
At Azulheim, your privacy is our highest priority. This Privacy Policy explains how Nail Shape AI handles your data — specifically the photos of your hands and nails that you submit for AI-powered analysis.
The short version: We process your photos temporarily to generate your nail analysis, then immediately and permanently delete them. We collect no personal information, create no user accounts, and store nothing on our servers.
Zero Photo Storage: Your hand/nail photos are never saved to any server or database
No Personal Data: We collect no names, emails, or identifying information
Device-Only Results: Your nail analysis results are stored only on your device
No Accounts Required: The app works without registration or login
No Ads, No Tracking: We do not use advertising networks or behavioral tracking
Photo & Image Data
This section explains exactly how we handle your photos in compliance with privacy regulations and Apple App Store requirements.
What Image Data We Process
Temporary Image Processing Only: When you voluntarily upload or capture a photo for nail analysis, we temporarily process the image to extract visual features such as nail shape, nail length, finger proportions, skin tone, nail health indicators, and hand characteristics.
No Biometric Database: We do NOT collect, store, or create any biometric databases, unique identifiers, or recognition templates from your photos.
No Identity Recognition: We do not use facial recognition or any technology to identify you as an individual. Analysis is purely focused on your nail and hand characteristics.
Voluntary Upload: You explicitly choose which photos to upload, and photo library or camera access requires your permission through iOS settings.
How We Use Your Photos
Purpose: Photos are used exclusively to generate a personalized nail shape analysis and style recommendations.
Processing Flow:
1. You select or capture a photo within the app
2. Image is optimized for transmission (compressed for efficient processing)
3. Image is sent via encrypted HTTPS to third-party AI providers
4. AI analyzes nail and hand features and returns results in text/JSON format
5. Analysis results are displayed on your device
6. Image is immediately and permanently deleted from all systems
Processing Duration: Images exist in temporary memory for approximately 5–15 seconds during active analysis only.
No Secondary Use: Images are NEVER used for advertising, marketing, AI model training, biometric recognition, or any purpose other than your requested nail analysis.
Where Your Photos Are Stored
On Your Device: Images exist only in temporary device memory (RAM) during the active analysis session. They are NEVER written to device storage, cached, or saved to the file system.
On Our Servers: We operate NO backend servers. We have no infrastructure to store, archive, or retain your images.
Third-Party APIs: Images are transmitted via encrypted HTTPS directly from your device to AI APIs. They process images transiently and do not permanently store them on our behalf.
iCloud/Backups: Images are never saved in a way that would be included in device backups or iCloud sync.
Photo Retention Period
Retention Duration: ZERO — No retention whatsoever
Timeline Breakdown:
• 0–3 seconds: Image selected and loaded into device memory
• 3–8 seconds: Image transmitted to AI provider via HTTPS
• 8–15 seconds: AI processing and analysis completion
• 15+ seconds: Image completely cleared from all memory
After Analysis: When you exit the analysis screen or close the app, iOS automatically deallocates all memory, including any temporary image data.
No Persistence: Images are never saved to UserDefaults, CoreData, the file system, or any persistent storage mechanism.
Third-Party Retention: Images are not permanently stored by third-party providers. Any temporary caching is handled according to their respective policies.
Your Rights & Control Over Your Photos
Photo Library Permission: You control whether the app can access your photo library via iOS Settings → Privacy & Security → Photos
Camera Permission: You control whether the app can access your camera via iOS Settings → Privacy & Security → Camera
Voluntary Upload: You choose which specific photos to analyze — we never access your library automatically
No Data Requests Needed: Since we don't store images, there are no photos for us to provide, modify, or delete upon request
Immediate Exit: You can close the app at any time during analysis to immediately stop processing and clear memory
Revoke Permissions: You can revoke camera/photo access permissions at any time in iOS Settings
Security Measures for Photo Data
Transport Encryption: All image transmission uses HTTPS with TLS 1.3 encryption
No Man-in-the-Middle: Direct device-to-API communication prevents intermediary data capture
Memory-Only Processing: Images never touch persistent storage layers (disk, database, file system)
Automatic Deallocation: iOS automatically clears memory when objects are no longer referenced
What Data We DO NOT Collect
We want to be absolutely clear about what we do not collect:
Your hand and nail photos are deleted immediately after AI analysis — we never store them
We don't collect names, emails, phone numbers, or any identifying information
Your past nail analyses are saved locally on your device for your reference — never on our servers
No device identifiers, location data, or usage analytics are collected
Our app doesn't require accounts, logins, or any registration process
We do not create biometric templates, hand recognition databases, or unique identifiers
