1. Information We Collect

We collect the following types of information:

  • Account information: name and email address, collected during sign-up via Apple Sign In, Google Sign-In, or email registration
  • Profile data: age range, gender, skin type, skin concerns, and skincare goals, collected during onboarding questionnaire
  • Skin photos: photos of your face taken through the in-app camera for skin condition analysis
  • Skincare products: product names, brands, and ingredient lists, collected via product photo scanning or manual search
  • Lifestyle data: sleep quality, stress levels, water intake, and diet information, collected through daily check-ins
  • Routine data: your skincare routine steps and daily completion records
  • Usage data: app interactions and feature usage, collected via Google Analytics

2. How We Use Your Information

  • To analyze your skin condition using AI-powered image analysis
  • To audit your skincare routine for ingredient conflicts, safety issues, and gaps
  • To generate personalized skincare routines and product recommendations
  • To track your skin progress and identify correlations between lifestyle and skin health
  • To recognize skincare products from photos you take
  • To answer your skincare questions
  • To improve and develop the Service

3. Data Storage & Security

Your data is stored securely using Supabase (hosted on AWS). We use industry-standard encryption and security measures to protect your information.

4. Third-Party Services & AI Data Sharing

We use the following third-party services:

  • Supabase: authentication, account management, and data storage
  • Apple Sign In / Google Sign-In: optional social authentication providers
  • Apple/Google: in-app payment processing and subscription management
  • RevenueCat: subscription status synchronization between the App Store/Play Store and our servers (no payment card details are processed by us or RevenueCat)
  • Google Analytics: anonymous usage analytics

AI Services

To provide personalized skincare analysis, the following data is sent to third-party AI services:

  • Anthropic (Claude AI) — receives your skin photos, skin type, concerns, profile information (age range, gender, pregnancy status), skincare product and ingredient lists, lifestyle data (sleep, stress), and routine adherence data. Used for skin condition analysis, routine audits, skincare routine generation, and routine evaluation.
  • Google (Gemini AI) — receives product photos you take. Used for product recognition (identifying brand and product name from images).

Your data is sent to these AI services only when you actively use features that require AI analysis (e.g., skin scan, routine audit, care plan, chat). Data is encrypted in transit via HTTPS. Your data is not used by these providers to train their AI models. Both Anthropic and Google maintain enterprise-grade security and data protection standards. For details, see the Anthropic Privacy Policy and Google Privacy Policy.

5. Payment & Subscriptions

Premium features are available through an auto-renewing subscription. Payment is processed by the Apple App Store or Google Play Store. We do not collect or store your payment card details on our servers.

Subscription Plans

  • Monthly: $9.99 / month
  • Annual: $69.99 / year (≈42% savings vs. monthly)
  • Free trial: 7 days, available to new subscribers only

Prices may vary by region as set by the App Store / Play Store. The actual price for your region is shown at the time of purchase.

Auto-Renewal

Your subscription automatically renews at the end of each billing period (monthly or annual) at the then-current price unless you cancel at least 24 hours before the end of the current period. The renewal charge is billed to your Apple ID or Google Play account. You can manage and cancel your subscription at any time in your App Store or Play Store account settings.

Free Trial

If you start a free trial, you will not be charged during the trial period. If you do not cancel before the trial ends, your subscription will automatically convert to a paid subscription at the price listed above. Any unused portion of a free trial is forfeited if you purchase a subscription before the trial ends.

Cancellation & Refunds

You can cancel your subscription at any time through your App Store or Play Store account. Cancellation takes effect at the end of the current billing period — premium access continues until then. Refund requests are handled by Apple or Google in accordance with their respective policies. We do not process refunds directly.

Subscription Data

We receive subscription status updates (active, expired, cancelled) from the App Store or Play Store via secure server-to-server notifications, processed by RevenueCat (our subscription infrastructure provider). This is used solely to determine whether your account has access to premium features. We do not receive your payment card details.

6. Cookies & Tracking Technologies

We use cookies and similar technologies for:

  • Essential cookies: required for authentication and core functionality
  • Analytics cookies: used by Google Analytics to understand how users interact with the Service

You can disable non-essential cookies through your browser settings. Disabling essential cookies may affect the functionality of the Service.

7. Data Sharing

We do not sell your personal information. We share data with the third-party services listed in Section 4, solely for the purpose of operating the Service. All third-party service providers we work with are contractually required to provide the same or equal level of data protection as described in this policy. We do not share your personal data with other users.

By using the Service, you consent to the transfer of your data to the United States.
