Privacy Policy
Last updated: June 1, 2026
SunFade ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the SunFade mobile application.
1. Information We Collect
We collect the following types of information:
- Skin profile data — skin type, tone, spot type, goals, and routine preferences you provide during onboarding or in your profile.
- Photos — weekly progress photos you take within the app. These are stored locally on your device using Expo FileSystem and are not uploaded to our servers.
- Routine and check-in data — your daily routine completions, streaks, and weekly check-in responses. Stored locally on your device.
- AI conversation data — when you use the Ask SunFade feature, the following data is sent to Anthropic's servers to generate your response: (a) your skin profile (skin type, spot type, goals, and other assessment answers), (b) your chat messages, and (c) any insights you have saved to your profile. This data is transmitted solely to generate your personalized response and is not retained after the response is delivered. Your explicit consent is requested the first time you use this feature.
- Subscription data — managed by RevenueCat. We receive anonymized subscription status information. We do not store payment details.
2. How We Use Your Information
- To personalize your skincare routine and protocol recommendations.
- To provide AI-powered skin advice through Ask SunFade.
- To analyze your progress photos with AI when you request it (SunFade+).
- To manage your subscription and access to SunFade+ features.
3. Data Storage
Your photos and personal skin data are stored locally on your device using AsyncStorage and Expo FileSystem. They are not uploaded to or stored on our servers.
AI queries are processed through our backend (hosted on Railway) and the Anthropic Claude API. Queries are not retained after the response is delivered.
4. Third-Party AI Service — Anthropic
The Ask SunFade feature is powered by Claude AI, operated by Anthropic, PBC. Before using this feature, you are asked for explicit consent inside the app. If you decline, no data is sent and the feature is unavailable.
Data sent to Anthropic:
- Your skin profile (skin type, spot type, main goal, and assessment answers)
- Your chat messages within Ask SunFade
- Insights you have saved to your profile
How Anthropic uses this data:
- Data is processed solely to generate your AI response.
- Your data is not used to train Anthropic's AI models. SunFade uses Anthropic's API, which operates under a data processing agreement that prohibits training on customer data.
- Data is not retained by Anthropic beyond the processing of each request.
