We collect the following types of information to provide and improve our sunset glow effect services, including sensitive facial data as detailed below:
- Portrait photos and images uploaded or captured via the app (including facial feature data contained within these images, such as facial contours, eye position, nose shape, mouth position, and other biometric facial characteristics that are necessary for applying sunset glow effects)
- Account registration information (if applicable): email address, username
- Payment information (for premium subscriptions): transaction details, billing address
- Device information: model, operating system, unique device identifiers
- Usage data: app interaction patterns, feature usage frequency, session duration
- Log data: IP address, timestamps, crash reports, diagnostic information
- Location data (if permitted): approximate geographic location for personalized content
We collect facial data only from portrait photos/images voluntarily uploaded/captured by users for the sole purpose of applying sunset glow light effects. The specific facial data points collected include:
- Facial contour coordinates (to map the outline of the face for effect application)
- Key facial feature positions (eyes, nose, mouth, cheeks, jawline) to ensure precise effect alignment
- Facial skin tone and texture data (to adjust sunset glow effect intensity and color matching)
Facial data is extracted locally on the user's device first, and only transmitted to our third-party AI services if the user explicitly consents (see Section 3 for details).
Collection methods include:
- Direct user input: Upload/capture of portrait images containing facial data via the app's camera or photo library access
- Automated processing: Local extraction of facial feature data from uploaded/captured images using on-device computer vision algorithms
- Third-party service integrations: Only with explicit user consent (see Section 3)
