AI-Powered Skin Analysis
When you use the skin analysis feature, your photos are processed as follows:
- On-device processing: Face detection is performed locally using Apple's Vision framework
- AI analysis: Photos are resized (max 800px) and temporarily sent to Claude AI (by Anthropic) for cosmetic analysis
- Secure transmission: All data is encrypted during transfer
- No permanent storage: Photos are not stored on AI servers after analysis
- No identity linking: Photos are processed anonymously without linking to your identity
- Cosmetic use only: Analysis provides cosmetic suggestions, not medical diagnoses
By using this feature, you consent to this processing. You can use the app without the AI analysis feature if you prefer.
Information Sharing
We do not sell, rent, or share your personal information with third parties for marketing purposes. Your data stays on your device and is not transmitted to external servers except for AI analysis as described above.
Your Photos
Photos you take for skin analysis are stored exclusively on your device. When you request an AI analysis, resized copies are temporarily processed by our AI provider (Anthropic) and immediately discarded after generating your results. Original photos remain only on your device and are never shared with third parties. Only you can view and access your stored photos.
