Overview

GĐ Công Giáo (Catholic Family) is a social platform designed for Vietnamese Catholic communities. The app provides community bulletin boards, direct messaging, friend connections, Catholic profile management, liturgical calendar, daily Bible verses, catechism resources, and family genealogy tools.

Account & Authentication

• Account required: You must create an account (via Google or Apple sign-in) to access the app's features.
• Data collected: Display name, email address, profile photo URL, gender, date of birth, diocese, parish, job, hobbies, and authentication provider identifier.
• Purpose: To identify you within the app, enable friend connections, community participation, and synchronize your data across devices.

Community Bulletin Board

GĐ Công Giáo provides a community bulletin board where members can share posts, photos, and interact through comments and reactions.

• Account required: You must sign in to post or interact with community content.
• Data collected: Posts (text, images), comments, reactions, timestamps, and user profile information are stored to provide the service.
• Content visibility: Posts are visible to all community members.
• Moderation: We may review content to ensure compliance with our Community Guidelines.
• Reporting: Users can report inappropriate content or behavior for review.

Direct Messaging

GĐ Công Giáo allows users to send text messages, images, and voice messages to friends within the app.

• Data collected: Messages (text, media files), timestamps, read receipts, and sender/receiver identifiers.
• Storage: Messages are stored on Firebase servers to enable real-time delivery and synchronization across devices.
• Media files: Images and voice messages sent in chat are uploaded to cloud storage and accessible only to chat participants.
• Encryption: All data is transmitted over encrypted connections (TLS/SSL). Messages are stored on secure cloud servers with access controlled by security rules.

Catholic Profile & Family Data

• Profile information: Your Catholic profile includes diocese, parish, occupation, hobbies, and personal introduction. This information is visible to other community members.
• Family tree: Family genealogy data (spouse, children, marriage information) is stored privately and only visible to you unless you choose to share it.
• Religious content: Liturgical calendar data, daily verses, and catechism resources are provided from public Catholic sources and do not require personal data.

Camera & Photos Access

• Purpose-limited: Camera and photo access is used for profile photos, community posts, and sending images in chat.
• Image compression: Images are compressed before upload to optimize storage and bandwidth usage.
• No identification: Images are not used for user identification or profiling.

Push Notifications

• Purpose: Push notifications are used to alert you about new messages, community posts, friend requests, and other important events.
• Data: Your device push notification token (FCM/APNs) is stored to deliver notifications. It is not shared with third parties.
• Control: You can disable notifications at any time through your device settings.

Friends & Contacts

• Friend system: You can add other users as friends using their nickname or search within the community. We do not access your device contacts.
• Data stored: Friend connections (user IDs) are stored to enable messaging features.
• Blocking: You can block users to prevent them from contacting you.

Location & Map (Explore)

• Purpose: The Explore tab displays a map of Catholic churches, parishes, and community places across Vietnam using Google Maps.
• GPS location: With your permission, we access your device's GPS to show your current location on the map and find nearby churches. Location access is only used while the app is open (foreground only).
• Location data: Your GPS coordinates are NOT stored on our servers or shared with other users. Location is used locally on your device only.
• Map data: Google Maps SDK may collect usage data according to Google's Privacy Policy.
• Community places: When you add a community place (church, parish, pilgrimage site), the place's coordinates, name, photos, and your profile info are stored and visible to all users.
• Permission: Location permission is optional. You can use the map without granting location access — the map will default to a general view of Vietnam. You can revoke location permission at any time through your device settings.

Data Storage & Retention

• Cloud data: Account information, chat messages, community posts, friend lists, and family tree data are stored on Firebase servers.
• Local data: App preferences and cached content are stored locally on your device.
• Media: User-uploaded media (avatars, post images, chat images/voice messages) are stored on secure cloud storage.
• Deletion: You may delete your account directly within the app (Profile → Settings → Delete Account). Upon deletion, all associated data will be removed from our servers within 30 days.
