We respect your privacy and are committed to protecting your personal data.
Lumina ("we", "our", or "us") operates the Lumina mobile application (the "App"), available on Android with package identifier com.linko.social. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App. Please read this policy carefully. If you disagree with its terms, please discontinue use of the App.
When you register or sign in (including via Google Sign-In), we collect your display name, email address, and profile photo URL provided by your Google account.
Posts, photos, videos, captions, comments, and other content you share on Lumina are stored in our Firebase infrastructure.
We collect analytics data (via Firebase Analytics) such as screens viewed, features used, session duration, and device model/OS version. This data is aggregated and used solely to improve the App.
Firebase Crashlytics collects crash reports including device state, stack traces, and App version to help us fix bugs. No personally identifiable content from your posts is included in crash reports.
If you allow notifications, Firebase Cloud Messaging (FCM) assigns your device a registration token used only to deliver in-app notifications such as likes, comments, and follows. We do not share this token with advertisers.
The App requests the following Android permissions:
| Permission | Purpose |
|---|---|
| CAMERA | Capture photos and videos to post on Lumina |
| READ_MEDIA_IMAGES / READ_MEDIA_VIDEO | Access photos and videos from your gallery to share as posts |
| READ_EXTERNAL_STORAGE (Android ≤ 12) | Legacy access to media on older Android versions |
| INTERNET | Connect to Firebase services and load content |
| ACCESS_NETWORK_STATE | Detect offline status to show appropriate UI feedback |
| POST_NOTIFICATIONS | Deliver push notifications (likes, comments, follows) |
| VIBRATE | Haptic feedback for notifications |
You can revoke any permission at any time in your device's Settings → Apps → Lumina. Revoking a permission may limit certain features.

Anonymized analytics and crash-report data may be retained longer in aggregate form, but cannot be linked back to you after account deletion.
Lumina is not directed to children under the age of 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal information, please contact us immediately and we will delete it.
