SKIN4U Privacy Policy

Last updated: October 2026

SKIN4U ("we", "our", "the app") is a skincare product and skin analysis application. This Privacy Policy explains what information we collect, how we use it, and the choices you have.

Information We Collect

• Account information: When you sign in with Google or Apple, we receive your name, email address, and profile picture.
• Skin profile: Information you provide in our questionnaire, such as skin type, concerns, goals, sensitivities, and city.
• Photos you choose to scan: Product photos and, if you choose to use it, face scan (selfie) photos. Both are sent to Google's Gemini AI service for one-time analysis and are not stored by SKIN4U, on your device or on any server, at any point. For product photos, only the resulting analysis (score, ingredients, description) is saved. For face scan photos, only the resulting text insights are saved (oiliness, hydration, redness levels) — never the photo itself. See "Face Scan Data" below for full detail.
• Usage data: such as products you save to your shelf, and your conversations with our in-app assistant, Mai.
• Purchase information: If you subscribe to SKIN4U Pro or Makeup4U Pro, we use RevenueCat and Apple to manage your subscription. We receive your subscription status and purchase history linked to your account, and no payment card details.
• Location: With your permission, we use your device location (or the city you entered) to show local weather-based skincare tips.

How We Use Your Information

• To provide personalized skincare product analysis and recommendations.
• To power our AI assistant, Mai, with context about your skin profile.
• To show weather-based tips relevant to your location.
• To manage your subscription and unlock the features you purchased.
• To improve and maintain the app.

How We Share Your Information

We do not sell your personal information. We use the following third-party services to operate the app:

• Google / Apple for sign-in authentication.
• RevenueCat and Apple for subscription and purchase management.
• Supabase for account management and secure backend functions.
• Google Gemini AI: We send scanned product photos, and your selfie photo if you choose to use the Face Scan feature, directly to Google's Gemini AI service (via our own secure backend) so it can generate the analysis you requested. We do not include your name, email, or other account information in this request — only the photo itself and, for product scans, your general skin profile (skin type, concerns, goals) so the analysis can be personalized to you. You are asked to consent to this before any photo is sent, either via the consent checkbox at sign-in or the Face Scan consent screen. See "Face Scan Data" below for additional detail specific to selfie photos.

Face Scan Data (Selfie Photos)

If you choose to use the optional Face Scan feature, here is exactly how that data is handled:

• What we collect: A single selfie photo you take within the app, only when you actively choose to use this feature.
• How it's used: The photo is sent to Google's Gemini AI service for one-time analysis, to generate general, non-medical insights such as oiliness, hydration, and redness levels. This is not a medical diagnosis.
• Third-party sharing: The photo is shared only with Google Gemini AI, solely for the purpose of generating this analysis. We do not share your face photo with any other third party, and it is never used for advertising or any purpose beyond generating your insights.
• Storage and retention: SKIN4U does not store the selfie photo itself, on your device or on any server, at any time. Only the resulting text insights (e.g. "oiliness: medium") are saved locally on your device, so the app can show your progress over time.
• Deletion: Because we never keep the photo, there is nothing further to delete after the analysis completes. You can delete the saved text insights at any time by deleting your account from Settings, which permanently removes all data associated with your account.

Data Storage

Most of your data (skin profile, saved products, face scan insights, scan history) is stored locally on your device. Your account authentication is managed securely by Supabase.

Your Choices

• You can edit your skin profile at any time from Settings.
• You can sign out at any time.
• You can permanently delete your account and data from Settings at any time.

Children's Privacy

SKIN4U is intended for users aged 18 and older. It is not directed at children or minors, and we do not knowingly collect information from anyone under 18. If you believe a minor has provided us information, contact us and we will delete it.
