Privacy Policy
This Privacy Policy explains how Color Sistser for Android, also known as 색언니 ("Color Sistser" or the "App"), handles information. The App is developed and provided by SungHoon Lee (이성훈) ("Developer" or "Service Provider") as a free app and is provided as is.
Information the App Uses
Color Sistser helps users check personal color tendencies by using the device screen, the front camera, and on-device color and face-position analysis. The current version may process the following information locally on your device:
- front camera preview frames used for face positioning, lighting checks, and color measurement;
- temporary face and skin-region measurements, such as brightness, color response, pose, motion, and quality indicators;
- personal color result data shown in the App, such as season candidates, axis scores, measurement confidence, and recommended color previews;
- device and display condition information needed for measurement quality, such as device model prefix, Android version, display mode, brightness state, and related quality flags; and
- local privacy-safe measurement diagnostics and records used to support measurement reliability and App features.
Camera frames, face-position information, skin-color measurements, result summaries, and local records are processed on your device. The Developer does not receive this information, and the App is not designed to upload, sell, or share it.
The current App package does not request Android's Internet permission and is not designed to transmit your camera content, personal color measurements, usage data, or diagnostics to the Developer's servers.
Camera and Face Processing
The App requests camera permission so it can show a front-camera preview and perform personal color measurement. The App uses on-device face detection to help check whether one face is visible, centered, stable, and within the expected measurement range. The App does not use face recognition, does not identify who you are, and does not create a face template for identifying you.
The current release does not store raw camera photos or videos for the Developer. A temporary face image may be held in memory during the current app session only to show recommended color previews, and it is not uploaded to the Developer.
Local Storage
The App may keep local settings and privacy-safe measurement diagnostics or records on your device when needed for App features, measurement reliability, or user-controlled local history. These records are designed to avoid raw face images and direct contact identifiers. They may include measurement quality metrics, device calibration-related information, result summaries, retry or failure reason codes, and non-identifying session information.
Android backup and device-transfer rules for the App are configured to exclude the App's private files, databases, and shared preferences. The Developer does not operate or access any Android or manufacturer backup systems.
Information the App Does Not Request
The App does not require an account. The Developer does not ask you to provide your name, email address, phone number, account information, or other direct contact identifiers through the App.
The App does not request or send precise or approximate location, contacts, messages, call logs, microphone data, advertising ID, payment information, remote usage analytics, crash reports, IP address, or device diagnostics to the Developer.
Third-Party Services
The current version of the App does not use third-party advertising, analytics, or crash-reporting SDKs. It uses Android platform components and on-device libraries such as CameraX and Google ML Kit face detection to provide camera preview and face-position analysis. These are used to run App features on the device and are not used by the Developer to receive your personal information.
Your Choices
You can deny camera permission, but camera-based measurement features may not work without it. You can stop local processing by closing or uninstalling the App. You can remove locally stored App data by clearing the App's storage in Android settings.
Children
The App is not directed to children under 13. The Developer does not knowingly collect personal information from children through the App.
Security
The App is designed so camera and measurement information stays on the device unless a future version clearly asks for your permission for another use. No method of local processing or electronic storage is perfectly secure, but the current version avoids developer-server collection and does not request Internet permission.
Changes
This Privacy Policy may be updated from time to time. When it is updated, the effective date above will be changed. You are encouraged to review this page periodically.
Your Consent
By using the App, you acknowledge the handling of information described in this Privacy Policy.
