1. Introduction
Hotify ("we," "our," or "the App") is a facial wellness application that analyzes facial features using artificial intelligence to provide personalized skincare and wellness insights. This Privacy Policy explains how we collect, use, store, and protect your information.
By using Hotify, you agree to the collection and use of information as described in this policy.
2. Information We Collect
2.1 Photos and Facial Data
- When you take or upload a photo for analysis, the image is temporarily held in device memory and transmitted securely (HTTPS/TLS) to our Firebase Cloud Function, which forwards it to OpenAI's API for analysis.
- The photo is never permanently stored — not on our servers, not in Firebase, and not on your device after analysis. OpenAI processes the image under their API data usage policy, which states that API inputs are not used for model training and are not retained after processing.
- The photo is held only for the duration of the API call (typically under 60 seconds) and is discarded from memory immediately after analysis completes.
- Only the derived results (numerical scores, text insights, color analysis) are stored in your Firebase account to enable progress tracking.
- Facial analysis focuses on wellness metrics such as skin clarity, symmetry, and proportions — not facial recognition or identification.
- We do not use face data for advertising, profiling, or any purpose other than generating your wellness analysis.
- You can delete all stored results at any time via Settings > Delete All Data.
2.2 Account Information
- We use anonymous authentication (Firebase Authentication). We do not require your name, email address, or phone number to use the App.
- A unique anonymous identifier is assigned to your account.
2.3 Profile Information
Gender and age range (provided voluntarily during onboarding) to personalize analysis metrics.
2.4 Usage Data
- Scan history and scores
- Routine completion data
- Subscription status
- App interaction events (when analytics are enabled)
2.5 Device Information
- Device type and operating system version
- App version
- Crash logs and performance data (when crash reporting is enabled)
2.6 Purchase Information
Subscription status and billing period are managed through Apple's In-App Purchase system via RevenueCat. We do not have access to your payment method or billing details.
3. How We Use Your Information
We use collected information to:
- Analyze facial features and generate wellness scores
- Provide personalized skincare routines and recommendations
- Track your progress over time
- Manage your subscription status
- Improve app performance and fix bugs
- Send routine reminders (with your permission)
4. Data Sharing and Third-Party Services
We use the following third-party services:
| Service | Purpose | Data Shared |
|---|
| Firebase (Google) | Authentication, data storage | Anonymous ID, profile, scan results |
| OpenAI | Facial analysis AI processing | Photos (transmitted for processing only, not stored or used for training per OpenAI API terms) |
| RevenueCat | Subscription management | Anonymous ID, purchase status |
| Mixpanel | Analytics (when configured) | Anonymous usage events |
| Sentry | Crash reporting (when configured) | Crash logs, device info |
| Apple (App Store) | Payment processing | Managed entirely by Apple |
We do not sell, rent, or trade your personal information to third parties for marketing purposes.
5. Data Storage and Security
- Your data is stored securely using Firebase Cloud Firestore with appropriate security rules.
- Photos sent for analysis are transmitted over encrypted connections (HTTPS/TLS).
- We implement reasonable security measures to protect your data from unauthorized access.
- Scan results and routine data are associated with your anonymous account ID.
6. Data Retention
- Face photos: Retained only for the duration of the AI analysis API call (typically under 60 seconds). The photo is never written to disk or permanently stored on any server.
- Analysis results: Scores, insights, and color analysis are retained as long as your account is active.
- You can delete all your data at any time through Settings > Delete All Data in the App.
- Upon deletion, all scan results, profile information, and routine history are permanently removed from our servers.
7. Children's Privacy
Hotify is not intended for children under the age of 13. We do not knowingly collect information from children under 13. If you believe a child has provided us with personal information, please contact us immediately.
8. Your Rights
You have the right to:
- Access your data (visible within the App)
- Delete all your data at any time (Settings > Delete All Data)
- Opt out of notifications (via iOS Settings)
- Cancel your subscription at any time
9. Push Notifications
We may send push notifications for routine reminders. You can disable notifications at any time through your device's Settings.
10. Health and Wellness Disclaimer
Hotify provides AI-generated wellness insights and routine suggestions for informational purposes only. The app does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making changes to your skincare, diet, or exercise routine. Where health-related claims are made, citations from reputable sources (such as the American Academy of Dermatology, NIH, or WHO) are provided where applicable.
11. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last Updated" date. Continued use of the App after changes constitutes acceptance of the updated policy.
