Privacy Policy

Effective: April 12, 2026 · Last updated: April 17, 2026

KOLUP ("the Service") respects your privacy. This Privacy Policy describes what information the Service processes and how.

1. Information We Collect

The Service does not require sign-up or password-based login. However, to improve service quality, it uses Firebase Anonymous Authentication to generate a per-device anonymous identifier (UID). We do not request your name, email, phone number, date of birth, or any other personally identifying information. We collect anonymized usage analytics to improve the Service.

2. Information Processed On Your Device

To provide core functionality, the following information is processed on your device or transmitted to third-party APIs. None of it is stored on our servers.

• Location (coordinates): With your permission, the app reads your device location and sends the coordinates to the Open-Meteo weather API (open-meteo.com) in order to recommend outfits suitable for current weather. We do not store your location.
• Camera and Photos: The app accesses your camera and photo library only when you choose to take or pick a photo for color extraction. Images are processed on-device only and are not uploaded or stored anywhere.
• Preferences: Settings you enter (gender, style keywords, clothing categories) are stored in local device storage (AsyncStorage) and removed when you uninstall the app.
• Cloud sync of onboarding selections: To improve recommendation quality and prioritize new curations, your onboarding selections (fashion keywords, clothing categories, app version, platform, language) are stored in Firebase Firestore (Google, US/Asia regions) keyed by an anonymous identifier (Firebase Anonymous UID). No name, email, or other directly identifying information is included. This data is deleted when you uninstall the app or upon request via the contact in section 7.
• Usage Analytics: We use Firebase Analytics (Google) to collect anonymized usage data such as screen views, button taps, and feature usage frequency. This data does not include advertising identifiers (IDFA) and cannot be used to personally identify you. Collected data is stored on Google servers (United States). See Firebase Privacy Policy.

3. Third-Party Services

We do not sell or share your information with third parties. The Service communicates with the following external services to provide functionality:

• Open-Meteo (open-meteo.com) — weather data (receives location coordinates)
• Cloudflare Pages (color-codi-assets.pages.dev) — CDN for outfit assets
• Google Firebase Analytics (firebase.google.com) — anonymized app usage analytics
• Google Firebase Authentication / Firestore (firebase.google.com) — anonymous identifier issuance and storage of onboarding selections

4. Data Retention and Deletion

Local device settings are removed when you uninstall the app. Onboarding selections stored in Firebase Firestore (keyed by an anonymous identifier) are deleted when you use Settings > Data Management > Delete Account in the app, uninstall the app, or upon request via the contact in section 7. We do not retain any other personal data.

5. Your Rights

You may revoke location, camera, or photo permissions at any time through your iOS Settings. Uninstalling the app removes all locally stored data. You can delete your cloud-synced onboarding selections and anonymous authentication data directly from the app via Settings > Data Management > Delete Account. Alternatively, contact us using the email in section 7 and we will erase them without undue delay.

6. Children's Privacy

The Service does not knowingly collect information from children under 13 (or 14 in Korea).
