Lumi Privacy Policy
Last Updated: May 25, 2026
📱 Summary: Lumi uses a local-first architecture. Your clothing photos and AI analysis results are stored on your device and are not uploaded to our servers.
Overview
Lumi (the "App") is developed by an individual developer ("we," "us," or "our"). This Privacy Policy explains how we collect, use, and protect information when you use our App.
Information We Collect
1. Account Information (Google Sign-In)
When you sign in with your Google account, we receive:
- Your Google account email address
- Your display name
- Your Google account ID (for identification purposes)
This information is used to create your Lumi account and is stored in Firebase Authentication and Google Firestore (basic profile data only).
2. Clothing Photos
Photos you take or select from your library are stored locally on your device only. Photos are NOT uploaded to our servers or any third-party cloud storage. You can delete the app and all local data at any time.
3. AI Analysis (Gemini)
When you add a clothing item, the photo is sent via Google Cloud Functions to Google Gemini AI for analysis to identify the item's type, color, and material, and to generate vector embeddings for similarity matching.
Photos are not permanently retained on Google servers after analysis. Results (type, color, material, vectors) are stored locally on your device.
4. Crash Reports (Firebase Crashlytics)
The App uses Firebase Crashlytics to collect crash reports to help us improve stability. Reports include device model, OS version, and error traces. They do NOT include personally identifiable information or your clothing data.
Information We Do NOT Collect
- Precise or approximate location
- Device advertising IDs (IDFA / GAID)
- Browsing history or third-party app usage
- Contacts or call logs
- Biometric data
- Payment or financial information
Data Storage
| Data Type | Storage Location | Retention |
|---|---|---|
| Account information | Google Firebase (encrypted) | While account exists |
| Clothing photos | Device local storage | Until you delete them |
| AI analysis results | Device local storage | Until you delete them |
| Crash reports | Firebase Crashlytics | 90 days |
